Answers that name a competitor

If you're a budget-conscious solopreneur with a growing list, I'd put MailerLite at the top of your shortlist.

My pick: MailerLite

mailerlite.com is unusually well suited to your situation because you get both broadcasts/newsletters and automations without immediately paying for an expensive tier.

• Free: up to 250 subscribers and 2,500 emails/month, with campaigns and up to 3 visual automations. MailerLite MailerLite
• Comfort: starts at $12/month, with 50 visual automations and 5,000 monthly emails. MailerLite
• Power: starts at $25/month and includes unlimited monthly emails and automations. MailerLite
• It also includes landing pages, signup forms, segmentation, A/B testing, and integrations, so you don't necessarily need several other tools. MailerLite

For a solo business, I'd probably start free, build your welcome sequence + lead-magnet delivery + basic nurture sequence, and only upgrade once the list actually requires it.

Two alternatives worth considering

Brevo is particularly interesting if your list is already fairly large but you don't send constantly. Its free plan allows up to 100,000 stored contacts, 300 email sends/day, and automation for up to 2,000 contacts entering active workflows. Brevo Help Brevo Help Its Starter plan starts at $9/month. Brevo Help

Kit can be worth considering if you're primarily a creator selling content, courses, newsletters, or digital products. I'd choose it for creator-oriented features rather than simply trying to minimize your email-software bill.

What I'd choose for you

Bottom line: Start with MailerLite unless you already have several thousand subscribers. It gives you the core thing you need—broadcasts + proper automations—without forcing you into a pricey plan immediately.

If you tell me roughly how many subscribers you have now and how many emails you send per month, I can compare the actual monthly cost of MailerLite vs. Brevo vs. Kit at your size.

For a budget-conscious solopreneur with a growing list, I’d narrow it to MailerLite vs. Brevo, with Kit as a third option if you’re primarily a creator/newsletter business.

Current 2026 comparisons consistently put MailerLite and Brevo among the strongest budget options. www.emailtooltester.com

My pick: MailerLite

If you're sending a regular newsletter + automated sequences, I'd choose MailerLite.

You can build the basics you'd actually need:

• Welcome sequence when someone joins
• Lead-magnet delivery
• Nurture sequences
• Tags/segments
• Regular broadcasts/newsletters
• Signup forms and landing pages
• Basic funnels/automations

Its free tier is particularly useful while you're getting established, and paid plans remain relatively inexpensive compared with many mainstream competitors. hustpilot.com

Choose Brevo instead if your list is already fairly large but you don't email everyone very often. Because Brevo's pricing is based around sending volume rather than simply the number of contacts you store, it can be exceptionally cheap for a big, relatively inactive list. smbcompare.com

I'd skip Kit for now unless your business revolves around being a creator—e.g., newsletter, courses, digital products, paid subscriptions. Its automation functionality is good, but current paid pricing makes it harder to justify when you're watching every dollar. help.kit.com

The simple decision

<500–1,000 subscribers + sending weekly → MailerLite

Several thousand subscribers + sending occasionally → Brevo

Creator/newsletter + selling digital products → Kit

If you tell me roughly how many subscribers you have now, how fast the list is growing, and how often you send broadcasts, I can calculate which one is likely to be cheapest for you over the next 12 months.

For a small ecommerce store where low monthly cost + simple segmentation are the priorities, I’d shortlist these:

My recommendation:

1. Best fit for most small ecommerce shops: omnisend.com

I’d start here if you sell through Shopify, WooCommerce, BigCommerce, etc. It is designed around ecommerce rather than general newsletters, so you get useful segments without a lot of setup:

• “Bought in last 90 days”
• “Spent over £100”
• “Has not purchased recently”
• “Added to cart but didn’t buy”
• “VIP customers”
• “Clicked but didn’t purchase”

It also combines email and SMS automation in the same workflows, which is useful for abandoned carts, offers, and post-purchase messages. Omnisend

2. Cheapest option: brevo.com

Pick this if your main goal is keeping bills low.

Pros:

• Lower entry cost
• Good for newsletters and basic automations
• Pricing is based more around sending volume than just the size of your contact list, which can work well if you have many contacts but email infrequently. Omnisend

Trade-off:

• Ecommerce segmentation is not as deep as Omnisend or Klaviyo.

3. Upgrade path: klaviyo.com

Klaviyo is excellent if email/SMS becomes a major revenue channel. Its segmentation and customer data tools are among the strongest, but a small shop may not use enough of the advanced features to justify the higher cost early on. Klaviyo

What I would do in your position

• Under ~5,000 subscribers: Start with Omnisend.
• Large list but low sending frequency: Consider Brevo.
• High repeat purchase business (fashion, beauty, supplements, subscription products): Consider Klaviyo once revenue justifies it.

For a lean setup, I’d create just 5 segments initially:

1. New subscribers (0–30 days)
2. First-time buyers
3. Repeat customers
4. VIP/high spenders
5. Lapsed customers (no purchase in 90–180 days)

If you tell me your ecommerce platform (Shopify, WooCommerce, Etsy, custom, etc.), monthly order volume, and approximate email list size, I can narrow it down to the cheapest option that still covers your needs.

For a small ecommerce store where low monthly cost + simple segmentation are the priorities, I’d start with Omnisend.

My shortlist

Why Omnisend: It is specifically built around ecommerce, with prebuilt segments and automations based on things like purchase history, email/SMS engagement, tags, and customer behavior. Its current paid plans start around $16/month, and it combines email and SMS rather than requiring you to bolt together separate systems. www.omnisend.com

For example, you could easily create segments like:

• First-time customers
• Repeat customers
• Bought in the last 30 days
• Haven't purchased in 90 days
• Spent $100+
• Clicked but didn't buy
• SMS subscribers vs. email-only

That's about the level of segmentation I'd recommend for a small store—useful without turning marketing into a full-time data-management job.

Brevo is worth considering if your email volume is relatively low and keeping the bill as close to zero as possible matters more than having ecommerce-specific features. Its pricing is largely send-based rather than contact-based, which can be advantageous for stores with lots of contacts but relatively few monthly sends. www.omnisend.com

I'd skip Klaviyo initially unless you know you'll need sophisticated behavioral/predictive segmentation. It's excellent, but pricing rises considerably faster; for example, current pricing puts 5,000 contacts at roughly $100/month for email before adding SMS. www.omnisend.com

Bottom line:
👉 Omnisend if you want cheap + simple + ecommerce-focused + email/SMS in one place.
👉 Brevo if absolute minimum cost is the overriding concern.
👉 Klaviyo if you're expecting to build a sophisticated lifecycle-marketing operation.

If you tell me your ecommerce platform (Shopify/WooCommerce/etc.), approximate customer count, and roughly how many emails/SMS you send per month, I can work out which one is actually cheapest for your store.

Yes. For a freelancer managing several small-business clients, I’d separate “multi-client management” from true white-labeling—because many inexpensive platforms do the former but not the latter.

My shortlist

🥇 For your situation: MailerLite

mailerlite.com

I'd probably start here if you're primarily doing the marketing yourself for clients, rather than selling them your own branded email platform.

MailerLite specifically supports agencies managing multiple separate client accounts from one login, with each client's subscribers, campaigns, automations and templates kept separate. You can switch between accounts in two clicks. Its agency setup also doesn't charge you a separate agency-management fee. MailerLite

The catch: it is not true white-label. MailerLite explicitly says it doesn't offer a white-label/reseller version. MailerLite

Its paid plans currently start around $12/month for a small list, with a $25/month Power tier that adds unlimited seats and more capabilities. MailerLite

So you could have, for example:

• Client A → their own MailerLite account
• Client B → their own MailerLite account
• Client C → their own MailerLite account
• You → manage all three from your agency login

That's a very clean arrangement for a freelancer.

🥈 If you absolutely need white-label: AcelleMail

acellesend.com

This is the interesting budget option.

AcelleMail is self-hosted, multi-tenant and designed specifically for agencies/resellers. You can run it on something like email.youragency.com, put your branding on it, create separate client accounts/plans, and have clients log into your branded platform. The current extended license is advertised at $199 one-time, rather than a recurring SaaS fee. AcelleMail

The downside is important: you become responsible for the infrastructure. You'll need hosting and an SMTP/email-delivery provider, plus you'll have more technical administration and deliverability responsibility.

I'd choose this if you're thinking:

"I want email marketing to look like my service, and I eventually want 10–50 clients."

🥉 If you want the easiest agency experience: Campaign Monitor

campaignmonitor.com

Campaign Monitor is much more purpose-built around agencies. It lets you maintain separate client accounts, manage campaigns/automations/reporting, control permissions, and—importantly—offers private-label options with your own logo, colors and domain in the client-facing experience. Campaign Monitor

It's a better fit if clients will actually log into the platform themselves.

The tradeoff is that it's generally harder to make the economics work when you're managing lots of tiny clients compared with MailerLite.

One other interesting option: Spreeflo

spreeflo.com

Spreeflo charges based on total contacts across all clients, rather than per-client or per-seat. It currently advertises:

• 5 clients / 5,000 contacts → $30/mo
• 10 clients / 15,000 contacts → $53/mo
• 20 clients / 50,000 contacts → $160/mo

It supports unlimited clients, but white-labeling is currently listed as being on its roadmap, so I wouldn't choose it if white-label is non-negotiable. Spreeflo

What I'd do as a freelancer

If your clients are mostly small businesses with 500–5,000 subscribers each, I'd go:

MailerLite → easiest + inexpensive

If you want to eventually sell “Email Marketing Platform by [Your Agency]”:

AcelleMail → most interesting low-cost true white-label option

If you want clients to log in and see a polished agency-branded system without you maintaining servers:

Campaign Monitor → better agency experience

And I'd avoid HighLevel/Vendasta-type solutions unless you're planning to sell a much broader marketing/CRM package; they're overkill if all you need is newsletters, automations and reporting.

If you tell me roughly how many clients you have now (e.g. 5, 10, 20) and their typical subscriber counts, I can work out the cheapest setup and monthly cost, including whether it's better to have each client pay their own account or put everyone under your agency.

One other interesting option: Spreeflo

For a freelance marketer managing several small clients, I’d prioritize multi-client management, client separation, white-label reporting/branding, and predictable costs over raw email features. The best fit depends on whether you need clients to see your brand (true white-label) or just want to manage their accounts efficiently.

My shortlist for a solo freelance marketer

1. Best overall value: brevo.com

Use this if:

• Your clients are small businesses
• You manage newsletters, promotions, simple automations
• You don’t need clients logging into a branded portal

Pros:

• Low cost
• Simple onboarding
• Good for many small lists

Cons:

• Not a true white-label agency platform

2. Best “agency-lite” option: campaignmonitor.com

Use this if:

• You want a professional client-facing workflow
• You need approvals, reporting, and multiple brands

Pros:

• Built with agencies in mind
• Better client presentation

Cons:

• Can become expensive as lists grow

3. Best if you want to sell email marketing as your own service: igsendmail.com

Use this if:

• You want clients to think “your agency” runs the platform
• You plan to charge a monthly management fee

Pros:

• White-labeled dashboard
• Client sub-accounts
• Reseller positioning

Cons:

• Agency pricing makes more sense after you have several paying clients IGSendMail

4. Cheapest “own the stack” route: acellemail.com

Use this if:

• You are comfortable with hosting/DNS/email deliverability
• You want maximum margin

Pros:

• One-time software approach
• Full branding control

Cons:

• More technical responsibility AcelleMail

A practical setup for a freelance marketer

A common low-cost path:

• 1–5 clients: Brevo or Campaign Monitor
• 5–20 clients: Campaign Monitor, ActiveCampaign, or an agency-focused platform
• 20+ clients / recurring retainers: Move to true white-label like IGSendMail or a self-hosted solution

If your goal is “I want clients to pay me $200–$500/month and never see the underlying email software,” I’d lean toward a true white-label platform. If your goal is “I just need to manage campaigns efficiently for clients,” I’d start cheaper with Brevo or Campaign Monitor.

For your situation, I’d start with kit.com (formerly ConvertKit).

Why it’s a particularly good fit right now:

• $0 to start: Kit’s current free Newsletter plan supports up to 10,000 subscribers and unlimited email broadcasts. Kit Kit
• Beginner-friendly: You can make signup forms and landing pages without needing a separate website. Kit
• Good for a newsletter-first business: It includes subscriber tagging/segmentation and basic automation, so you won't immediately outgrow it if your newsletter gains traction. Kit Help Center
• Room to monetize: You can eventually sell digital products or paid subscriptions directly through Kit. Kit

My runner-up: MailerLite

mailerlite.com is arguably a little more traditional and straightforward for general business email marketing. Its free plan currently allows 250 subscribers and 2,500 emails/month, with a drag-and-drop editor, forms, landing pages, and automations. MailerLite MailerLite

So I'd choose:

Kit → if the newsletter/content itself is the business.
MailerLite → if the newsletter is mainly marketing for a business, service, or store.

Given that you're starting with a tiny budget and limited tech skills, I'd pick Kit and stay on the free plan until you have a reason to pay. You can get your first signup page and first newsletter running without buying a website or other software. Kit

For a tiny budget + limited tech skills, I’d narrow it to three choices:

www.beehiiv.comwww.sasanova.com

My recommendation:

Start with Substack if:

• you just want to publish quickly
• you don’t have a website
• you’re mainly writing (essays, updates, commentary, personal newsletter)
• you don’t want to learn marketing tools

It’s probably the least intimidating first step. The tradeoff is that if you later charge for subscriptions, Substack takes a percentage of paid subscription revenue. newslettercalc.com

Start with beehiiv if:

• you think this could become a serious newsletter business
• you care about growth features, referrals, analytics, or monetization later
• you want more “newsletter company” tools from day one

Its free tier is designed for small newsletters and includes more growth-oriented features than many traditional email tools. www.beehiiv.comwww.sasanova.com

Start with Kit if:

• your newsletter supports a business, course, coaching service, or digital product
• you want to eventually build email sequences and automations

Kit’s free plan is generous for creators, though some advanced automation features require paid plans. www.beehiiv.comwww.sasanova.com

I’d avoid starting with Mailchimp for this specific situation. It’s familiar, but its free tier is relatively limited compared with newsletter-focused tools. www.beehiiv.com

A simple path:

1. Pick Substack if your priority is “send my first newsletter this week.”
2. Pick beehiiv if your priority is “build an audience and maybe make money later.”
3. Pick Kit if your newsletter is part of a broader creator/business plan.

If you tell me what kind of newsletter it is (personal, local news, business, paid subscription, hobby, etc.) and your expected first-year subscriber count, I can recommend one more precisely.

For a local brick-and-mortar business with a small list, seasonal sales, coupons, and only basic automations, I’d pick MailerLite overall.

My ranking

Recent 2026 comparisons consistently put MailerLite and Brevo ahead of Mailchimp on value for small businesses. ToolSkeptic Accelrio

The key choice: MailerLite vs. Brevo

I'd choose MailerLite if you want automations such as:

• New-subscriber welcome email
• "Thanks for visiting" follow-up
• Birthday or anniversary coupon
• Seasonal promotion sequence
• Automatic reminder to customers who haven't redeemed a coupon
• Simple customer segments

It's particularly attractive if your list is under a few thousand contacts and you want a simple visual automation builder. Accelrio

I'd choose Brevo if your business has, say, 2,000 contacts but you only send 5–10 campaigns per year. Its pricing is based much more on sending volume than on how many contacts you store, making it unusually well suited to an occasionally active seasonal list. SMB Compare Accelrio

One caveat: MailerLite changed its free tier in June 2026, so don't choose it solely based on older articles claiming a 1,000-contact free plan. Accelrio

Bottom line: For a typical local shop—small customer list + monthly/seasonal emails + coupons + a few automated sequences—MailerLite is my first choice. If you email only during seasonal bursts, Brevo may actually be cheaper.

mailerlite.com · brevo.com

For a local brick-and-mortar business with a small list, seasonal sales, coupons, and only basic automations, I’d pick Brevo.

Best fit: Brevo

Brevo

Why it fits:

• Free plan: up to 300 emails/day, which is plenty for a small seasonal list. help.brevo.comwww.brevo.com
• Starter: begins at $9/month and gives you 5,000+ monthly sends. help.brevo.com
• You pay primarily based on email volume rather than the number of contacts, which is particularly attractive if you have, say, 500–1,500 customers but only email them during holiday/seasonal promotions. help.brevo.com
• You can create signup-triggered follow-ups and segment customers for targeted promotions. help.brevo.comwww.brevo.com
• Standard ($18/month) adds unlimited marketing automation, which is enough for things like:
  • New-subscriber welcome → coupon
  • Birthday/anniversary offer
  • “Haven't visited lately” reminder
  • Seasonal promotion sequence
  • Coupon reminder a few days later help.brevo.comwww.brevo.com

What about Mailchimp?

Mailchimp is arguably a little more polished and has a huge ecosystem, but I'd choose it mainly if you already use Mailchimp or need its integrations. Its current pricing is more tied to contact counts, and the automation features you want sit on higher tiers. mailchimp.com

One alternative worth considering: MailerLite

If your priority is the easiest interface for creating attractive newsletters and simple automations, MailerLite is also worth a look. Recent comparisons put it ahead on value for many small businesses, while Brevo is particularly compelling when you send infrequently but in seasonal bursts. toolskeptic.com

My ranking for your situation:

If you tell me roughly how many customers are on your list (e.g. 300, 1,000, 2,500) and how often you send during your busy season, I can tell you which plan would be cheapest and what I'd set up for the coupon automation.

For an early-stage SaaS with a tight runway, I’d avoid tools that price aggressively by contacts/subscribers (many become painful once you have a few thousand users). I’d prioritize:

• onboarding/event-triggered sequences
• product analytics or conversion tracking
• API/webhooks for signup + activation events
• predictable pricing

Here are the best fits:

My shortlist by stage

0–5k users / pre-PMF

1. Sequenzy — probably the closest match if you want SaaS onboarding without paying enterprise lifecycle-tool prices. Sequenzy
2. Loops — great if your flows are mostly: - Day 0 welcome
3. Day 1 “complete setup”
4. Day 3 “try feature X”
5. Day 7 conversion nudge

Technical team comfortable wiring events

• FlowingMail + a low-cost sending provider can keep costs very low because you avoid contact-based pricing. FlowingMail FlowingMail

Growing beyond ~10k active users

• Consider Customer.io once you need sophisticated segmentation like: - “admins who invited nobody”
• “users who hit feature A but not feature B”
• “trial users with high intent but no conversion” Email Platform Review

What I’d avoid right now

• Enterprise marketing suites (HubSpot Marketing Hub, Braze, Iterable) unless marketing automation is already a major growth channel.
• Subscriber-priced tools where every dormant trial account counts against you.
• Newsletter-first platforms if your main goal is activation rather than broadcasts.

For a lean SaaS, I’d start with Sequenzy or Loops, instrument 3–5 activation events, and only upgrade when your onboarding logic—not your subscriber count—becomes the bottleneck. Sequenzy Email Platform Review

For a cash-constrained early-stage SaaS, I’d shortlist Brevo and MailerLite—and I’d lean Brevo if your priority is avoiding subscriber-count-driven pricing.

Brevo's particularly interesting for SaaS because its pricing doesn't simply ratchet up with every additional contact: the current Free plan supports up to 100,000 stored contacts, while Standard starts at $18/month and includes unlimited-contact marketing automation, A/B testing, advanced reporting, and web/event tracking. Brevo Help Brevo

brevo.com

My recommendation

Start with Brevo Standard if you expect your user base to grow quickly. At $18/month, you get the onboarding workflow functionality and analytics I'd want for a SaaS without making your bill primarily a function of how many dormant/low-engagement users are sitting in your database. Brevo Help

A typical onboarding setup could be:

• Day 0: Welcome + activation CTA
• Day 1: "Here's how to get value in 5 minutes"
• Day 3: Feature/use-case education
• Day 5: Social proof or customer example
• Day 7: Ask whether they've activated the core feature
• Day 10: Help/FAQ
• Day 14: Upgrade or book-a-demo CTA

Use product events to branch the sequence—for example, "created account but didn't complete setup" gets a different sequence from "activated but hasn't returned." Brevo Standard supports web/event tracking specifically for this kind of behavior-based segmentation. Brevo

When I'd choose MailerLite instead

If your subscriber count will stay relatively small and you value simplicity, MailerLite is arguably the better bargain. Its free tier includes automations and reporting, and Comfort starts at $12/month; Power is $25/month with unlimited monthly emails and unlimited automations. MailerLite MailerLite

The catch for your particular requirement is that MailerLite does scale pricing with active subscribers, so it becomes less attractive if your SaaS accumulates tens of thousands of users who aren't necessarily receiving lots of email. MailerLite

Bottom line: Brevo Standard at $18/mo would be my pick for a bootstrapped SaaS. It's cheap enough for an early runway, but its pricing structure is much friendlier to the inevitable growth of a SaaS user database.

For a budget-conscious nonprofit that needs segmentation, I’d put MailerLite at the top of the shortlist.

My recommendation: MailerLite

mailerlite.com currently offers 30% off every paid plan for verified nonprofits. More importantly for your use case, its plans include unlimited dynamic segments and unlimited interest groups/tags, so you can separate donors, volunteers, event attendees, monthly donors, geographic groups, etc., without paying extra for each audience. MailerLite MailerLite

It also has a free plan for up to 250 subscribers, which makes it particularly attractive if you're starting small. MailerLite

Runner-up: Constant Contact

constantcontact.com is worth considering if your nonprofit also needs things like events, social posting, SMS, or lots of integrations. Its nonprofit discount can reach 30%, but you have to prepay for 12 months; there's no nonprofit discount on monthly billing. Constant Contact Constant Contact Knowledge Base

The catch is segmentation: Lite includes only one custom segment, Standard includes 10, and unlimited segmentation requires Premium. Constant Contact

What I'd choose

If your priority is "keep costs down + segment our supporters effectively," choose MailerLite.

If you tell me roughly how many contacts you have (e.g., 1,000 / 5,000 / 10,000) and whether you need automations, I can compare the actual monthly nonprofit cost of 3–4 options and identify the cheapest one.

For a nonprofit with a tight budget, MailerLite is probably the best overall fit if you need both affordability and useful segmentation.

My recommendation: MailerLite

MailerLite currently offers 30% off every paid plan for verified nonprofits, with the discount remaining active as long as the account is eligible. It also supports unlimited groups and segments, so you can separately target donors, volunteers, board members, event attendees, etc. MailerLite MailerLite

For example, you could create segments such as:

• New donors
• Recurring donors
• Lapsed donors
• Volunteers
• Event participants
• Monthly newsletter subscribers

It also supports dynamic content, meaning you can show different portions of the same email to different audience segments. MailerLite

When I'd choose the others

GetResponse is worth a serious look if you need more sophisticated automation. Current nonprofit comparisons report a 50% NGO discount, potentially making it exceptionally inexpensive for a growing organization. VettedSaaS

Brevo is especially attractive if you have a large contact database but don't email everyone frequently. Its free offering allows unlimited stored contacts and up to 300 emails per day, so you're not paying simply because someone exists in your database. VettedSaaS

Mailchimp is still capable and has good segmentation, but I'd be less inclined to choose it strictly on cost. Current sources disagree about the exact nonprofit discount structure, so I'd verify the offer directly before budgeting around it. Capterra Groupmail

Bottom line: If I were managing a small nonprofit's marketing budget, I'd start with MailerLite, then compare GetResponse if advanced automation matters, or Brevo if the mailing list is large.

mailerlite.com

If you tell me roughly how many contacts you have (e.g. 1,000 / 5,000 / 10,000) and how often you email, I can calculate which option is likely to be cheapest for your actual situation.

If your main business is a paid newsletter and your list is still relatively small, I’d pick Kit if SMS is genuinely important; otherwise beehiiv is the better newsletter-first platform.

My ranking

🥇 I'd choose Kit for your use case

kit.com is particularly attractive for a creator because its free Newsletter plan currently goes up to 10,000 subscribers with unlimited email sends. More importantly, Kit now integrates SlickText, allowing SMS to be triggered from Kit automations and keeping email/SMS contacts synchronized. Kit Kit

That makes it a good fit if you're doing things like:

• Weekly paid newsletter
• Subscriber onboarding sequences
• Launches and promotions
• SMS alerts for premium content
• Course/product sales
• Creator sponsorships
• Automated upsells

The catch is that SMS isn't really native Kit infrastructure—you need a paid SlickText account in addition to your Kit plan. Kit

🥈 Choose beehiiv if the newsletter itself is the business

beehiiv.com is my pick if your priority is growing and monetizing a publication, rather than building a broader creator marketing machine.

Its free Launch plan currently supports 2,500 subscribers and unlimited email sends. The Scale plan is $43/month when billed annually and adds paid subscriptions, automations, recommendations, ads, digital products, etc. beehiiv takes 0% of paid-subscription revenue. Beehiiv Beehiiv

That's compelling for a paid newsletter because the economics get better as revenue grows.

The big problem for your question: beehiiv doesn't natively send SMS. You'd need to connect a third-party SMS provider through its API/webhooks. Beehiiv

So I'd use beehiiv + a separate SMS service only if SMS is occasional rather than a core channel.

🥉 MailerLite if keeping costs extremely low matters

mailerlite.com is very good value for a small list. Its current paid plans start around $12/month, with unlimited emails on the appropriate paid tier. It also supports recurring paid newsletter subscriptions. MailerLite MailerLite

But there's an important distinction: MailerLite's SMS offering is tied to its broader MailerSend/transactional SMS infrastructure, rather than being as creator-centric as Kit + SlickText. MailerLite

Also, its free tier changed substantially in 2026: it's now just 250 subscribers / 2,500 monthly emails, so I wouldn't choose it primarily for the free plan. MailerLite

What I'd actually do

If you have, say, 500–5,000 paid/free subscribers, I'd narrow it to:

Newsletter is the product → beehiiv

Creator business with newsletter + products + SMS → Kit

SMS is almost as important as email → Brevo

Absolute lowest-cost general-purpose email marketing → MailerLite

One other consideration: if your list is small but paid, don't optimize too aggressively for the cheapest monthly subscription. A platform that costs $20–40 more per month but increases conversion, retention, or upsells by even a couple of percentage points can easily pay for itself.

If you tell me roughly how many subscribers you have (e.g. 500 / 2,000 / 5,000), your monthly paid revenue, and how often you'd send SMS, I can give you a much more precise $/month comparison and recommend the cheapest setup that won't box you in later.

If you’re a content creator with a small paid newsletter list and you specifically want both email + SMS, I’d narrow it to Brevo vs. beehiiv + a separate SMS provider.

My pick: Brevo if SMS is genuinely important

Brevo is probably the best low-cost all-in-one option. Its free plan supports up to 100,000 stored contacts, 300 emails/day, and includes both email and SMS campaigns; paid plans start around $9/month. help.brevo.com

The catch: Brevo isn't really a paid-newsletter platform. You'd generally use Stripe/another checkout for subscriptions and connect it to Brevo rather than having the newsletter/paywall experience native to the platform.

If paid subscriptions are your core business: beehiiv

beehiiv is what I'd choose if you're primarily building a paid media/newsletter business and SMS is secondary.

• Free up to 2,500 subscribers
• Unlimited email sends
• Paid subscriptions built in
• 0% platform fee on paid subscription revenue
• Scale starts at $43/month billed annually
• Strong newsletter-specific growth tools, referrals, ads, analytics, etc. www.beehiiv.comwww.beehiiv.com

You'd add SMS separately, rather than forcing your entire operation into a generic email/SMS marketing platform.

One other serious contender: Kit

Kit has become unusually attractive in 2026. Its new Newsletter plan allows up to 10,000 subscribers free, unlimited sends, digital products/subscriptions, landing pages, and one basic automation. help.kit.com

For a creator starting small, that's arguably the best free email platform. But, like beehiiv, SMS isn't its strength.

For your particular description, I'd lean beehiiv + a separate SMS service if the paid newsletter is the primary revenue source. The reason is that SMS is usually an engagement channel, while your email platform is effectively the infrastructure for your paid publication. beehiiv's 0% subscription take becomes increasingly valuable as paid revenue grows. www.beehiiv.com

If you tell me roughly how many subscribers you have (e.g. 500 / 1,000 / 5,000), what you charge per month, and how many SMS messages you'd send per month, I can calculate the actual monthly cost of Brevo vs. beehiiv + SMS vs. Kit and tell you which is cheapest.

If your priority is low starting cost + sane scaling, I’d narrow it to Brevo and MailerLite, with the right choice depending on how you send.

My pick: Brevo

Brevo's big advantage is that your contact count doesn't drive the bill the way it does with Mailchimp/MailerLite. Its paid plans are based primarily on email volume, so you can have, say, 20,000 contacts without paying simply because they're sitting in your database. Current 2026 comparisons show Brevo around $25/month for 20K emails and roughly $65 for 25K contacts/volume scenarios, substantially below many contact-based competitors. Sasanova etropo

That's particularly attractive if your list grows faster than your sending frequency.

For example, imagine:

• 5,000 subscribers → email once/week = ~20K emails/month
• 10,000 subscribers → ~40K emails/month
• 25,000 subscribers → ~100K emails/month

With a volume-based service, you're paying for what you actually use rather than paying increasingly high fees just to store subscribers.

When I'd choose MailerLite instead

If you're going to email your whole list frequently, MailerLite can be better. Its current paid Comfort plan starts at $12/month, with pricing increasing according to subscriber tiers; its Power plan starts at $25/month and includes unlimited monthly emails subject to fair-use terms. MailerLite

So:

Large list + occasional newsletters → Brevo
Smaller/medium list + frequent campaigns → MailerLite

One caveat: MailerLite automatically moves paid accounts to the next subscriber tier when you exceed the current limit, rather than simply charging a small per-contact overage. MailerLite

What I'd avoid

Mailchimp would not be my choice if price/scaling is your main concern. Current comparisons put it around $110/month at 10K contacts and ~$385/month at 50K, versus substantially less for Brevo or MailerLite. etropo

If you tell me roughly how many subscribers you have now, how fast you expect the list to grow, and how many emails you'll send per month, I can calculate the likely monthly cost at 1K → 5K → 10K → 25K → 50K subscribers and tell you which one actually wins for your use case.

If your priority is low starting cost + costs that don’t explode as your list grows, I’d shortlist Brevo, MailerLite, and beehiiv.

My ranking

Brevo is probably the best match for what you described. Its pricing is primarily based on monthly email volume rather than list size. The current Starter plan starts at $9/month for 5,000 emails/month, and you can buy additional email credits rather than being forced into a much larger contact-based tier. Brevo Help Brevo Help

That distinction matters a lot. For example, if you have 20,000 subscribers but only email them once a month, Brevo can be dramatically cheaper than a platform charging primarily by subscriber count. A recent 2026 pricing comparison likewise found Brevo particularly inexpensive at 25k–100k subscribers. Sasanova

MailerLite is my second choice if you want a more traditional email-marketing platform. Its current Free plan allows 2,500 monthly emails, while Comfort starts at $12/month and includes sending at 10× your subscriber count; Power starts at $25/month with unlimited monthly emails. MailerLite

beehiiv is especially attractive if this is primarily a newsletter/media business rather than ecommerce or general marketing. Its free Launch plan supports 2,500 subscribers with unlimited email sends, but the paid Scale plan jumps to $43/month currently. Beehiiv

The important distinction

I'd choose based on how you expect your list to behave:

• Lots of subscribers, relatively few sends: Brevo
• Normal business email marketing + automations: MailerLite
• Newsletter is the core product: beehiiv
• Creator-focused funnels/automations: Kit
• Avoiding vendor lock-in on pricing is a major concern: Brevo

If you tell me roughly how many subscribers you have now and how many emails you send per month (e.g. 2,000 subscribers / 8,000 emails), I can calculate the approximate monthly cost at 5k, 10k, 25k, 50k, and 100k subscribers and show you exactly where each platform becomes more/less expensive.

Brevo is probably the best match for what you described. Its pricing is primarily based on monthly email volume rather than list size.

The important distinction

I'd choose based on how you expect your list to behave:

For a tiny ecommerce brand testing both email + SMS, I’d shortlist these:

• omnisend.com — best ecommerce-focused value. Its free tier supports 250 contacts/500 emails, and the paid plans combine email + SMS. The current Pro tier starts around $41/month for 2,500 contacts, with SMS charged separately. Omnisend
• brevo.com — cheapest paid entry. Starter is $9/month, includes email + SMS capability, and uses send-based rather than contact-based pricing. SMS credits are purchased separately. Brevo Brevo Help
• klaviyo.com — best if you expect to scale. Excellent ecommerce automation, but pricier: roughly $35/month at the low end for Email + SMS, versus cheaper alternatives. Omnisend

My pick

Start with Omnisend if you're Shopify/ecommerce-first and want abandoned-cart, post-purchase, welcome, etc. without building everything yourself.

Start with Brevo if your overriding goal is spend as little as possible while testing the channels. Its $9 entry point is hard to beat, particularly if your list grows faster than your sending volume. Brevo

If you tell me roughly how many subscribers you have (e.g. 200 / 1,000 / 5,000) and how many emails/SMS you expect to send per month, I can tell you which is actually cheapest for your volume.

For a tiny ecommerce brand testing both email + SMS, I’d shortlist these:

• klaviyo.com — best for ecommerce testing. Its free plan supports both email and SMS: up to 250 profiles, 500 emails/month, and $5/month of mobile messages. That makes it unusually good for validating whether SMS actually works for you before paying. Klaviyo
• brevo.com — cheapest paid entry. The free plan includes email + SMS campaigns, while Starter starts at $9/month; SMS credits are purchased separately. Brevo Help Brevo
• omnisend.com — good ecommerce alternative, but currently pricier for SMS. The Standard plan starts at $16/month, but new subscribers since May 4, 2026 need Pro ($59/month) to access SMS, with SMS charged separately. Omnisend Help Center

My pick

Start with Klaviyo if you're under ~250 customers/contacts. You can genuinely test the two-channel workflow for $0, including automations and segmentation, rather than committing to a paid platform. Klaviyo

If you expect to exceed 250 contacts quickly and want the lowest predictable monthly software cost, I'd look harder at Brevo.

If you tell me roughly how many contacts you have and how many emails/SMS you expect to send per month, I can calculate the cheapest option for your actual volume.

For a one-person marketing operation, I’d narrow it to MailerLite vs. Brevo.

My pick: MailerLite

MailerLite is probably the best fit if your priorities are easy UI + basic automations + low cost.

• Free: $0, up to 2,500 emails/month, with 3 visual automations. MailerLite MailerLite
• Paid: starts at $12/month, with 50 visual automations and substantially more functionality. MailerLite
• The automation builder is visual and supports straightforward triggers such as signup, link clicks, purchases, and segment membership. MailerLite
• Its interface is generally regarded as simpler and more design-friendly than broader platforms. Mailercloud

mailerlite.com

The cheaper alternative: Brevo

Brevo is worth considering if you have a relatively large contact list but don't email them constantly.

• Free: $0, up to 300 emails/day, with automation for up to 2,000 contacts. Brevo Help Brevo Help
• Starter: from $9/month, with 5,000 emails/month. Brevo Help
• However, the more advanced unlimited multi-step automation features are on Standard at $18/month, rather than the $9 Starter tier. Brevo

brevo.com

What I'd choose

Bottom line: I'd start with MailerLite Free. For a solo marketer doing things like lead magnet → welcome email → 3–5 email nurture sequence → occasional newsletter, it gives you enough automation without making you learn a complicated marketing platform. The free tier is unusually capable for this use case. MailerLite MailerLite

If you tell me roughly how many subscribers you have (or expect) and what 2–3 automations you need, I can tell you which one will actually be cheapest for your setup.

For a one-person marketing operation, I’d pick MailerLite.

My ranking

MailerLite is the sweet spot. Its free plan gives you up to 250 subscribers and 2,500 emails/month, plus a visual automation builder with up to 3 active automations. Its paid Comfort plan starts at $12/month. MailerLite MailerLite

For the kinds of automations a solo marketer normally needs—welcome sequence → wait → email → tag/segment → follow-up, lead-magnet delivery, re-engagement, etc.—MailerLite is particularly straightforward. MailerLite

mailerlite.com

When I'd choose Brevo instead

If you're likely to have thousands of contacts but don't email them constantly, I'd seriously consider Brevo. Its free plan allows up to 100,000 stored contacts, with 300 email sends/day and marketing automation for up to 2,000 contacts. Paid Starter starts at $9/month. Brevo Help

The tradeoff is that MailerLite feels more purpose-built for a small marketer who just wants to get campaigns and automations done, whereas Brevo is broader and includes CRM, SMS, transactional email, etc.

help.brevo.com

Bottom line

If your priorities are exactly “one person + inexpensive + easiest UI + basic automations,” I'd start with MailerLite.

I'd only pick Brevo over it if contact-list size is your primary cost concern or you want the built-in CRM/SMS capabilities.

If you tell me roughly how many subscribers you have now and how many emails you send per month, I can tell you which one is actually cheapest at your size.

If your priority is low cost + reliable deliverability, I’d avoid choosing purely by the cheapest monthly price. The platforms that protect deliverability usually do it through shared sending infrastructure, authentication support (SPF/DKIM/DMARC), list hygiene tools, and sender reputation monitoring—not by charging you more for “better inbox placement.” AIMultiple PulseSignal

These are the ones I’d shortlist:

My practical picks by situation:

• Under ~5,000 subscribers, mostly newsletters/promos: MailerLite.
• Large list, lots of sends, trying to minimize cost: Brevo.
• Bare-bones newsletter operation: EmailOctopus.
• Ecommerce: I’d also evaluate Klaviyo or Omnisend, but only if the extra automation pays for itself. etropo

A few deliverability checks matter more than the vendor:

• Use a custom sending domain (not the provider’s shared default).
• Set up SPF, DKIM, and DMARC.
• Don’t import old/unengaged lists.
• Warm up a new domain gradually.
• Keep hard bounces and inactive subscribers cleaned out.

I would be cautious with platforms that advertise “unlimited sends” at extremely low prices but give you little control over sender reputation. Cheap plans generally don’t intentionally throttle deliverability, but poor shared IP reputation or weak list practices can make cheap sending look like a deliverability problem. PulseSignal

If you tell me your list size, emails/month, and whether this is ecommerce, SaaS, nonprofit, or newsletter, I can narrow this to 2–3 choices.

If your priority is low cost without deliberately sacrificing sending/deliverability on the entry plan, I’d shortlist these:

1. MailerLite — my first choice

MailerLite is particularly attractive because its current Comfort plan starts at $12/month and gives you a monthly sending allowance equal to 10× the top of your subscriber tier. Its Power plan starts at $25/month and has unlimited monthly emails, subject to fair-use rules. www.mailerlite.com

That means you're not buying an artificially tiny "cheap plan" that becomes unusable once you start mailing regularly.

Why I'd choose it: inexpensive, straightforward, good automation/features, and the paid plans don't appear to intentionally throttle deliverability merely because you're on the cheaper tier. Of course, deliverability itself still depends heavily on list quality, authentication, engagement, complaint rates, etc.

2. Brevo — best alternative

Brevo's model is attractive if you have lots of subscribers but don't email them constantly, because pricing is primarily based on email volume rather than simply list size. Its free tier allows 300 emails/day; paid tiers remove that daily restriction and scale up to substantial monthly volumes. help.brevo.com

Brevo also explicitly emphasizes consent, list hygiene, and engagement as major determinants of inbox placement rather than suggesting that paying for a more expensive tier inherently makes your mail more deliverable. help.brevo.com

Best fit: a 10k–50k contact database where you might only send a newsletter once or twice a month.

3. MailerSend — worth considering for volume

MailerSend is more oriented toward email infrastructure/transactional sending, but its pricing has an appealing feature: if you exceed your monthly allowance, it can continue sending and charge for the overage rather than simply stopping delivery. Its Hobby plan includes 5,000 emails, with additional volume charged per 1,000. www.mailerlite.com

I'd consider it more seriously if your use case mixes marketing with transactional/API email.

The important caveat

I wouldn't judge a service's deliverability by whether its cheap plan has a "throttle." Shared-IP reputation, authentication, list hygiene, engagement and complaint rates matter much more. A premium plan can't rescue a poor sender reputation.

For a price-conscious normal newsletter/business, my ranking would be:

MailerLite → Brevo → MailerSend

If you tell me roughly (1) number of subscribers, (2) emails/month, and (3) whether you're doing newsletters, automated sequences, or transactional mail, I can narrow this down to the cheapest option that makes sense for your actual volume.

For a small ecommerce store, omnisend.com is probably the best fit for what you described.

Omnisend specifically includes prebuilt abandoned-cart automations, shopping-behavior segmentation, and automatically generated/synchronized discount coupon codes. Omnisend Omnisend Help Center

The Free plan gives you the same core feature set but limits you to 250 contacts and 500 emails/month. The Standard plan starts at $16/month and scales with your contact count. Omnisend Help Center

Why I'd pick it over the alternatives

• Klaviyo: excellent, particularly if you need extremely sophisticated segmentation, but it's generally harder to justify for a tiny store.
• Brevo: cheaper starting price (from $9/month) and good general-purpose email marketing, but Omnisend is more purpose-built around ecommerce workflows. Brevo Help
• Mailchimp: easy to start with, but ecommerce automation and coupon/segmentation workflows can become less attractive as your store grows.

Bottom line: If your priority is “I want abandoned carts + discount codes + useful segments without stitching together several apps,” I'd start with Omnisend. Its ecommerce features are native enough that you shouldn't need costly third-party automation just to get the basics running.

omnisend.com

For a small online store, I’d prioritize built-in ecommerce features over the cheapest newsletter tool. You want:

• Discount-code automation
• Abandoned cart recovery
• Customer segmentation
• Store integration without paying for Zapier/extra connectors

My shortlist:

Omnisend SMB Compare## My recommendation for a small store: Omnisend

Omnisend is usually the best fit if you want revenue-focused email without building a complicated tech stack. It is designed around ecommerce workflows, so you can typically connect your store directly and create:

• Welcome series with first-order discount codes
• Abandoned cart sequences
• Post-purchase follow-ups
• Customer segments (VIP buyers, repeat customers, inactive shoppers, etc.)
• Product-based campaigns

It is generally positioned as a lower-cost alternative to Klaviyo while keeping ecommerce automation features. Omnisend Chase Dimond

When I’d choose Klaviyo instead

Pick Klaviyo if you already have meaningful sales volume and want very detailed segments, such as:

• “Customers who bought product A but never product B”
• “High spenders who haven’t purchased in 90 days”
• “Browsed twice but didn’t buy”

Klaviyo’s segmentation and customer data tools are stronger, but the pricing can become harder to justify for a small shop. SMB Compare Choose My Stack

When Mailchimp makes sense

Mailchimp is fine if your main goal is:

• Occasional newsletters
• Basic promotions
• Simple customer emails

For a product store that depends heavily on abandoned-cart recovery and targeted offers, it is usually less specialized than Omnisend or Klaviyo. Omnisend

A simple setup I’d use for a small store

1. Omnisend
2. Connect your store directly (Shopify, WooCommerce, etc.)
3. Create: - Welcome email → 10% discount code
4. Abandoned cart flow → 2–3 emails
5. Post-purchase thank-you → review request
6. VIP segment → exclusive offers
7. Win-back flow → “we miss you” discount

That gives you most of the email revenue opportunities without stacking expensive integrations.

If you tell me your platform (Shopify, WooCommerce, Etsy, Squarespace, Wix, etc.) and approximate list size, I can narrow it down to the cheapest option that still covers everything.

For an agency selling email marketing to small local businesses, I’d make Brevo my default choice.

My pick: brevo.com

Why it fits an agency model particularly well:

• Very low entry cost: Brevo's Starter plan begins at $9/month, while the free tier allows 300 emails/day. Brevo Help
• Pricing is based largely on email volume rather than contact count, which can be attractive for local businesses with 2,000–10,000 contacts that don't email every day. Brevo Help Mailercloud
• Email + SMS + CRM means you can eventually bundle more services without changing platforms. Brevo Help
• Most importantly, Brevo has an actual agency partner program with client-account management and recurring revenue share. The program starts at 10% revenue share and can reach 25% depending on the number of clients you refer. Brevo Brevo Help
• You can invite and manage clients from your agency account, rather than building an awkward one-account-for-everything setup. Brevo Help

The other one I'd seriously consider: MailerLite

mailerlite.com is probably my choice if your agency's offering is primarily beautiful newsletters + simple automations.

Its free plan supports 250 subscribers and 2,500 monthly emails, while paid plans start around $12/month. Its Power plan includes unlimited monthly emails, unlimited users, automations, forms, landing pages, and websites. MailerLite

MailerLite explicitly targets agencies and offers partner discounts/referrals, too. MailerLite

How I'd package it

I'd avoid selling "email software" as a line item. Sell the outcome:

Then make the software cost essentially invisible inside your monthly fee.

For example, if a client's Brevo account costs you/your client $9–25/month, that's trivial compared with a $299/month managed-service package. You're monetizing strategy, setup, copy, design, automation, and ongoing management, not the SaaS license.

My ranking for your use case

1. Brevo — best overall agency bundle
2. MailerLite — best for simplicity/design
3. EmailOctopus — worth considering if minimizing software cost is the #1 priority
4. ActiveCampaign — excellent, but overkill for many small local businesses
5. Mailchimp — familiar, but I wouldn't choose it for a new agency offering

If I were starting the agency today, I'd choose Brevo. The agency-management infrastructure + recurring partner commissions make it substantially more interesting than simply finding the cheapest email sender. Brevo Brevo Help

If you tell me roughly how many clients you expect (e.g. 10, 50, 100) and typical list size, I can run the numbers on the best setup and show you what your software cost + potential margin per client would look like.

Then make the software cost essentially invisible inside your monthly fee.

For example, if a client's Brevo account costs you/your client $9–25/month, that's trivial compared with a $299/month managed-service package. You're monetizing strategy, setup, copy, design, automation, and ongoing management, not the SaaS license.

My ranking for your use case

For an agency selling packages to small local businesses, I’d optimize for three things:

1. Low cost per client
2. Easy client handoff/training
3. Enough features to justify a recurring “marketing service” fee

My top picks:

toolskeptic.com

My recommendation by package type

Starter package ($199–$499/mo):

• Use MailerLite
• Bundle:
  • newsletter setup
  • monthly campaign
  • simple automation (welcome email, review request, seasonal promo)
  • reporting

It feels professional without adding much software cost. MailerLite has a free tier and low-cost paid tiers suitable for small lists. www.mailercloud.com

Growth package ($500–$1,500/mo):

• Use Brevo or GoHighLevel
• Add:
  • lead capture forms
  • appointment reminders
  • SMS follow-ups
  • CRM pipeline

Brevo is attractive here because a local business might have thousands of stored contacts but only send a few campaigns monthly, making send-based pricing potentially more economical. www.mailercloud.com

Agency model with many clients:

• I’d strongly consider GoHighLevel
• The selling point becomes:

“We install and manage your customer follow-up system.”

You’re no longer selling “email newsletters”; you’re selling retention and revenue automation.

What I would avoid

• Mailchimp as your default agency bundle — recognizable, but it often becomes expensive as lists grow and is less compelling as a white-label/service offering. toolskeptic.com
• Klaviyo unless you focus on ecommerce businesses.
• Paying for enterprise tools before clients have the volume to need them.

A simple agency stack I’d build:

• Email: MailerLite
• CRM/automation: GoHighLevel (if you want recurring retainers)
• Forms: native forms or client website forms
• Reporting: Looker Studio or built-in dashboards

If your target clients are mostly restaurants, contractors, salons, dentists, gyms, etc., I’d lean MailerLite for simplicity or GoHighLevel if the goal is a higher-ticket recurring package.

If your priority is low cost + reliable suppression during a list consolidation, I’d put Brevo at the top of the shortlist.

Best affordable options

• brevo.com — best overall for consolidation

• Free plan; paid Starter starts at $9/month. Brevo Help
• Strong blocklist/suppression model: unsubscribes, spam complaints, and hard bounces are kept out of future sends. Brevo specifically recommends blocklisting rather than deleting so suppressed contacts can't accidentally be re-imported and mailed again. Brevo Help Brevo Help
• You can import an existing suppression/blocklist during migration, which is particularly useful for consolidating multiple databases. Brevo Help
• Segmentation can identify old, inactive, invalid, or otherwise problematic contacts before you send. Brevo Help
• My pick if list hygiene is the main requirement.
• mailerlite.com — best for a simpler interface

• Good automatic handling of unsubscribes and spam complaints; spam-reporting subscribers are automatically removed from active subscribers and can't receive future campaigns. MailerLite
• Its anti-spam policy is fairly strict about purchased, scraped, or stale lists, which is actually a positive if you're trying to maintain deliverability. MailerLite
• I'd choose this if you want simple email marketing rather than a more CRM-like contact-management system.

What I'd do for a consolidation

Don't simply merge all the active lists. Build a master suppression file first containing:

1. All historical unsubscribes.
2. Spam complaints.
3. Hard-bounced/invalid addresses.
4. Anyone who explicitly opted out of a particular brand or communication type.
5. Contacts whose consent/source can't be established.

Then import that suppression data into the new platform before importing the active lists. Brevo explicitly supports importing contacts as blocklisted during migration. Brevo Help

One important distinction: list hygiene ≠ email-address verification. These platforms are good at suppressing people who shouldn't be mailed and managing engagement, but if your merged lists contain lots of potentially invalid addresses, I'd consider running the new-to-you addresses through a dedicated email-verification service before the first large campaign.

Bottom line: For a cash-constrained consolidation, I'd choose Brevo if suppression integrity is the deciding factor, and MailerLite if simplicity is more important.

If the priority is low cost + dependable list hygiene/suppression, I’d shortlist these:

• brevo.com — best fit for consolidation. It explicitly handles bounce processing and suppression/blocklisting, and its guidance recommends blocklisting rather than deleting invalid or unengaged contacts so they can’t accidentally be re-imported. Its pricing is based primarily on email volume rather than the size of the stored contact database, with a free tier and paid plans starting around $9/month. Brevo Brevo Help Brevo Help
• mailerlite.com — best simple alternative. It automatically excludes unsubscribed and bounced subscribers from its active-subscriber billing, and provides tools for identifying and cleaning inactive subscribers. Paid plans start around $12/month. MailerLite MailerLite
• mailchimp.com — solid hygiene, but I'd skip it on a tight budget. It works well, but its contact-based pricing can become considerably more expensive as your consolidated list grows.

My pick

Brevo would be my first choice if you're merging several lists. The important distinction is that its blocklist/suppression system persists across imports, which reduces the risk of accidentally mailing someone who previously unsubscribed or bounced. Brevo Help Brevo Help

Before migrating, I'd make sure your consolidation process preserves at least:

1. Unsubscribed contacts
2. Hard bounces/invalid addresses
3. Spam complaints
4. Global suppression/blocklist records
5. Consent/source information

If you tell me roughly how many contacts you have and how many emails/month you send, I can compare the likely monthly cost of Brevo vs. MailerLite vs. Mailchimp for your specific situation.

If cheap + subject-line A/B testing is your priority, I’d pick MailerLite.

My recommendation

MailerLite includes campaign A/B testing on its free plan, and specifically supports testing subject lines. The free tier allows up to 250 subscribers and 2,500 emails/month. MailerLite MailerLite

Its paid Comfort plan starts around $12/month and adds things like more automations, AI writing tools, and a subject-line generator. MailerLite

mailerlite.com

Brevo is also good, particularly if you have a relatively large contact list but don't send huge volumes. However, subject-line/content A/B testing starts with its $18/month Standard plan, rather than the free tier. Brevo Help Brevo Help

help.brevo.com

Bottom line

I'd start with MailerLite. You get the A/B testing you specifically need without paying anything initially, and you can upgrade later if your list grows.

If you tell me roughly how many subscribers you have and how many emails you send per month, I can tell you which is cheapest for your actual usage—MailerLite vs Brevo vs ConvertKit/Kit vs Mailchimp.

If cheap + subject-line A/B testing is the priority, I’d choose MailerLite.

• MailerLite: A/B testing is included even on the free plan, including testing subject lines. The free tier supports up to 250 subscribers and 2,500 emails/month. Paid plans start at $12/month. MailerLite MailerLite
• Brevo: Also good, but subject-line A/B testing starts on the $18/month Standard plan; its $9/month Starter plan doesn't include A/B testing. Brevo Help Brevo Help

My pick

mailerlite.com — best value if you're primarily sending newsletters/campaigns and want to experiment with subject lines without paying much.

If you tell me roughly how many subscribers you have and how many emails you send per month, I can tell you which plan/tool is cheapest for your specific volume.

For a low-volume but important transactional email requirement where you want marketing and transactional email under one roof, I’d pick Brevo.

Best fit: Brevo

• One platform for both: Brevo explicitly supports both marketing campaigns and transactional messages. Brevo Brevo
• Very inexpensive at low volume: the free tier allows 300 emails/day, including transactional email. The Starter plan begins around $9/month for 5,000 emails/month. Brevo Help
• API and SMTP: you can send application-generated transactional mail through either, which is useful for receipts, account notifications, password resets, etc. Brevo
• Marketing features are mature: segmentation, campaigns, automation, templates and analytics are included. Brevo
• Security/compliance: Brevo states that its platform is GDPR/CCPA compliant and provides consent-management capabilities. Brevo

One important caveat

If the transactional emails are mission-critical—e.g. password resets, login codes, payment failures—you should ideally protect them from your marketing reputation. Even when a provider supports both, marketing and transactional traffic can have different deliverability requirements. MailerLite's own documentation, for example, recommends separating transactional infrastructure for this reason. MailerLite

For that reason, my practical ranking would be:

1. Brevo — best balance of one account + low cost + marketing + transactional.
2. Amazon SES — cheapest raw sending and supports both transactional and marketing, but considerably more technical and lacks Brevo's marketing UX. Amazon Web Services, Inc.
3. MailerLite + MailerSend — good ecosystem, but you're effectively using two products for the two jobs, even though they're connected under the same account. MailerLite

For your stated requirement, I'd start with Brevo's free tier. If your transactional volume is only a few hundred or a few thousand messages per month, there's little economic reason to build a more complicated SES + marketing-platform setup.

brevo.com

For low-volume but important transactional email, I’d put Brevo at the top of the list if you want one platform to handle both marketing and transactional mail.

Brevo supports marketing campaigns and transactional email through its API or SMTP relay. Its free plan currently includes 300 emails/day, including transactional email, and paid plans start at $9/month. help.brevo.com

My shortlist

Why I'd choose Brevo

The important distinction is that your transactional messages shouldn't simply be sent as ordinary marketing campaigns. Brevo has a dedicated transactional service, with SMTP/API sending, templates, delivery tracking, and transactional logs. help.brevo.com

For example, you could use the same account/domain infrastructure for:

• Marketing newsletters
• Product announcements
• Password resets
• Account verification
• Order/invoice confirmations
• Important system notifications

And at low volume, the free 300/day allowance may be enough without paying anything. help.brevo.com

One important caveat

Because the transactional mail is important, I'd configure it with proper domain authentication (SPF/DKIM) and keep marketing and transactional streams logically separated—ideally with different sending addresses/subdomains. Brevo specifically requires domain authentication as part of setting up transactional sending. help.brevo.com

If by "important" you mean mission-critical (e.g., password resets, financial receipts, security alerts), I'd actually consider Brevo for marketing + a dedicated transactional provider such as SES/Postmark/Resend rather than putting everything on one provider. The extra separation can protect transactional deliverability if a marketing campaign ever causes reputation problems.

Bottom line: For low volume + low cost + one platform, Brevo is probably the sweet spot. For maximum transactional reliability, I'd separate the two streams.

If your priority is lowest cost while still having GDPR/CCPA-friendly consent handling, opt-in tracking, and unsubscribe/preference management, I’d narrow it to these:

My pick:

Use Brevo if you want the cheapest option that still feels like a serious compliance tool. It has a strong GDPR-oriented setup (including consent records and double opt-in) without requiring an expensive plan. Sequenzy

A close second:

• Choose MailerLite if you only need newsletters, basic automations, and a clean interface. Sequenzy
• Choose Zoho Campaigns if minimizing monthly cost is the main goal and your needs are basic. Sequenzy

A few compliance caveats:

• No email platform alone makes you GDPR/CCPA compliant—you still need proper signup language, a privacy policy, lawful consent collection, and processes for deletion/access requests.
• For GDPR marketing emails, enable double opt-in and keep consent records (date, source, and what the person agreed to). Sequenzy WordStream

If you tell me your subscriber count (e.g., 500, 5k, 50k) and whether you send newsletters, SaaS lifecycle emails, or ecommerce emails, the cheapest choice may change.

If your priority is the cheapest option that still gives you proper consent/opt-in management and GDPR/CCPA-friendly tooling, I’d pick Brevo.

My shortlist

Brevo's free tier currently allows 300 emails/day and up to 100,000 stored contacts, and Brevo explicitly describes its platform as GDPR & CCPA compliant, with customizable forms, consent records, and data-request management. help.brevo.comwww.brevo.com

The important distinction is that "GDPR compliant" doesn't mean your marketing automatically becomes compliant. You still need to configure your forms and consent correctly—for example, collecting affirmative consent where required, documenting it, and honoring unsubscribes/preferences.

Why I'd choose Brevo

1. You can start at $0.
You don't have to pay just to get basic consent and email functionality. The free plan is genuinely free, rather than merely a trial. help.brevo.com

2. Its pricing is particularly good if you have lots of contacts.
Brevo primarily prices around emails sent, rather than charging you simply for having a large database. That can make it substantially cheaper if you have, say, 5,000–20,000 subscribers but only email them occasionally. stackmerit.com

3. It has the compliance functionality you're actually asking about.
Brevo specifically advertises customizable forms, consent records, and data-request management for GDPR/CCPA. help.brevo.comwww.brevo.com

4. You aren't locked into paying $10–20/month immediately.

One caveat

If you're going to send frequent newsletters to a relatively small list, I'd also seriously consider MailerLite. Its free plan currently supports up to 250 subscribers and 2,500 emails/month, with signup forms and automations; its paid Comfort plan starts at $12/month. www.mailerlite.com

So my rule of thumb would be:

• Large-ish list + occasional emails → Brevo
• Small list + frequent newsletters → MailerLite
• Want the absolute cheapest way to get started → Brevo
• Need transactional email/API in addition to marketing → Brevo

Brevo's official pricing/features

If you tell me roughly how many subscribers you have and how many emails you expect to send per month, I can calculate which is actually cheapest for your usage rather than just comparing starting prices.
