Answers that name a competitor

For a small ecommerce shop on a tight budget, I’d look first at Omnisend.

• Free plan: Yes.
• Abandoned-cart emails: Included in the free tier, with prebuilt ecommerce workflows. Omnisend Omnisend
• Segmentation: Included, including behavioral/customer segments. Omnisend
• Free-tier scale: Current comparisons put it around 250 contacts and 500 emails/month. Omnisend
• Ecommerce focus: It integrates with platforms such as Shopify, WooCommerce, and BigCommerce and is designed around cart, purchase, and lifecycle events. Omnisend

omnisend.com

My budget ranking

1. Omnisend — best fit if abandoned-cart automation + segmentation are must-haves on $0.
2. Klaviyo — stronger/deeper segmentation, but its free tier is also limited to roughly 250 profiles/500 emails, so I'd choose it if advanced customer-data targeting matters more. Omnisend
3. Brevo — attractive if you have a large contact list but relatively low sending volume, though its free tier isn't as straightforward for ecommerce abandoned-cart automation. Nexa
4. Mailchimp — I wouldn't pick it specifically for this use case; its free automation capabilities are much more restricted. Omnisend

Bottom line: If you're starting small and want to spend nothing, Omnisend is probably the best match because the free plan actually gives you the two features you care about rather than making abandoned-cart automation a paid-only feature.

If you tell me whether you're on Shopify, WooCommerce, Wix, or something else, I can narrow it down to the cheapest option for your exact setup.

For a new newsletter for indie creators, I’d start with beehiiv.

My shortlist

• 🥇 beehiiv — best overall for you. Its free Launch plan supports up to 2,500 subscribers, unlimited sends, a newsletter website, analytics, custom domains, and a recommendation network. That gives you plenty of runway without paying while you're building. Beehiiv
• 🥈 Kit — best if you want the simplest creator-focused setup. Its free tier is especially generous—up to 10,000 subscribers—and it's designed around creators rather than traditional email marketing. Newsletter Math Sasanova
• 🥉 Substack — best if you literally want zero setup. It's free regardless of subscriber count, but takes 10% of paid-subscription revenue, so I'd be less inclined to build a serious monetized business there. LetterDuck

What I'd choose for your specific situation

Go with beehiiv if:

• You're serious about growing beyond 1,000 subscribers.
• You want a proper newsletter publication rather than just an email list.
• You might eventually make money through sponsors, paid subscriptions, or other newsletter monetization.
• You don't want to migrate platforms when you hit 1,000.

Go with Kit if:

• You're primarily an individual creator building an audience.
• You want something particularly straightforward.
• You expect to sell courses, digital products, coaching, etc. later.
• The 10,000-subscriber free ceiling is more attractive than beehiiv's 2,500.

I'd skip Mailchimp for this. It's more of a general-purpose marketing platform, and for a tiny creator newsletter you're likely paying for complexity you don't need.

My vote: beehiiv. The free plan is unusually capable, and you're not going to immediately run into a "congratulations, you have 1,001 subscribers, now pay us" problem. Beehiiv

beehiiv.com

If you tell me what kind of indie creators you're targeting (writers, indie hackers, artists, YouTubers, etc.), I can also recommend the best newsletter + landing page + analytics stack that stays $0/month.

Yes — brevo.com is probably the best fit for what you described.

• Free email marketing: 300 emails/day, with a large contact allowance. Brevo Help Brevo
• SMS campaigns: SMS marketing is built into the same platform. The catch is that SMS itself isn't free; you purchase SMS credits/pay as you send. Brevo Help
• Good for a solopreneur: You get email campaigns, SMS, transactional messaging, and a drag-and-drop editor without needing a separate SMS platform. Brevo Help
• No credit card required to start on the free plan. Brevo

One important alternative

mailerlite.com is arguably nicer if your priority is selling digital products and building email automations. Its current free plan includes 250 subscribers, 2,500 emails/month, visual automations, landing pages, and digital-product selling. MailerLite MailerLite

However, Brevo wins if SMS is a requirement, because SMS is native to the platform.

My pick for you: Start with Brevo if you want email + occasional SMS in one place. Start with MailerLite if SMS is only a "nice to have" and you care more about email funnels/digital-product selling.

If you tell me roughly how many subscribers you have and how often you'd send SMS, I can tell you which one I'd choose for your specific setup.

For a cash-strapped nonprofit, I’d put Sender and Brevo at the top of the list, with MailerLite as another strong option.

Sender specifically markets its platform to nonprofits and currently advertises 2,500 subscribers, 15,000 emails/month, responsive templates, automation, segmentation, and a 25% nonprofit discount. Sender

My recommendation

Try Sender first. For a nonprofit with limited funds, its combination of a relatively generous free allowance, donor-oriented positioning, templates, and automation is hard to beat. Sender

Choose Brevo instead if you have a very large donor/contact database but don't email everyone frequently. Its free model is based heavily on sending volume rather than the number of contacts, making it attractive for large lists. Capterra MailToolFinder

One important caveat: deliverability isn't determined by the platform alone. Maintaining permission-based lists, authenticating your domain (SPF/DKIM/DMARC), removing inactive addresses, and avoiding spammy fundraising language will matter enormously.

If you tell me roughly how many donors you have and how often you send, I can narrow this down to the cheapest option that should work well for you.

Best fit: MailerLite. For an early-stage SaaS with a tiny list, it gives you onboarding sequences without requiring a credit card: its free plan includes up to 250 subscribers, 2,500 monthly emails, and 3 automations. MailerLite

Other solid options:

• Brevo — better if you expect the list to grow quickly; free plan has no credit card requirement, unlimited contacts, and automation features (with sending limits). Brevo Help
• Kit (ConvertKit) — good for creator-style onboarding, but less SaaS-focused.
• HubSpot Free — useful if you want CRM + email basics, though automation depth is limited.

For SaaS onboarding, I’d set up:

1. Signup trigger → welcome email immediately
2. Day 1 → “quick start” guide
3. Day 3 → feature tip
4. Day 7 → activation check-in
5. Inactive users → re-engagement email

For a tiny SaaS list, I’d start with MailerLite and switch only when you need advanced behavioral events (e.g., “created project but didn’t invite teammate”). MailerLite

If you’re an agency testing CRMs before migrating real client lists, I’d prioritize platforms with a genuine free tier, contact import, enough workflow functionality to run a realistic pilot, and—critically—an easy exit.

My agency shortlist

1. HubSpot — best first pilot.
It supports importing existing contacts and gives you a broad ecosystem around CRM, sales, service and marketing. HubSpot's current site advertises a free-forever core CRM with no credit card required, although its public pages currently show somewhat inconsistent contact/user limits, so I'd verify the limits presented during account creation before loading a client database. HubSpot HubSpot

2. Zoho — best if you want to test actual CRM depth.
The free edition is particularly attractive for an agency because you can test leads, deals, fields, tasks and basic workflow without immediately paying. Current comparisons put it at 3 users and roughly 5,000 records on the free plan. InterObservers Free Alternatives To

3. Brevo — best if the migration is really CRM + email marketing.
It is worth testing when your clients' contact lists are primarily used for campaigns and follow-ups rather than complex sales pipelines. Current comparisons report a free plan supporting a very large contact database, while limiting daily email volume. Tajo Deliver by Make Sense

4. Freshsales — good specialist pilot.
I'd test this when phone/email interaction is central to the agency's workflow. Its free tier is aimed at small teams and includes contact, account and deal management plus communication capabilities. InterObservers

5. Bitrix24 — test cautiously.
Its combination of CRM, projects, chat and collaboration can be compelling for an agency, but free-tier restrictions around exports and other functionality make it less attractive if your priority is easy migration back out. Dupple

How I'd run the agency evaluation

Don't immediately upload an entire client list. Take 100–500 representative records and test:

• CSV import and field mapping
• Duplicate detection
• Custom fields
• Multiple pipelines/client types
• Tags, segments and saved views
• Email/calendar integration
• Automations and follow-up tasks
• User permissions
• Client-by-client separation if you're managing multiple accounts
• API/Zapier/Make connectivity
• Full data export back to CSV
• Deletion of the test data

The export test is especially important. A platform can be "free forever" yet still make leaving painful. Independent 2026 comparisons specifically flag export restrictions as a potential source of lock-in, particularly with Bitrix24. InterObservers Dupple

For an agency, I'd start with HubSpot + Zoho, put the same anonymized 200-record dataset into both, and have your team perform the same 5–10 workflows. That will tell you far more than feature-comparison tables.

Yes. If tag-based segmentation and custom fields need to be genuinely free, I’d shortlist these:

• mailerlite.com — best overall for traditional email marketing. Its free plan currently supports interest groups (tags), dynamic segments, and custom fields, with up to 250 active subscribers and 2,500 emails/month. MailerLite MailerLite
• beehiiv.com — best if you manage multiple newsletters/publications. Its free Launch plan supports up to 3 publications, subscriber tagging, custom fields, and segmentation. Beehiiv Beehiiv
• buttondown.com — excellent lightweight newsletter option. It supports tags and subscriber metadata for segmentation, and lets you create multiple newsletters. However, its tags are listed as available on the Basic plan, so I wouldn't choose it if "free forever" is the strict requirement. Buttondown Docs Buttondown
• brevo.com — good for large lists with low sending volume. The free plan allows unlimited contacts and 300 emails/day, while segmentation can use contact attributes/custom data. Brevo Brevo Help

My pick for your use case

If you have multiple newsletters and want to tag the same subscriber according to interests, I'd pick beehiiv if the newsletters are publications, or MailerLite if they're more like marketing/email campaigns.

For example, you could have:

Subscriber → Tech + AI + Weekly Digest

and send Newsletter A only to Tech, Newsletter B to AI, etc.

If you tell me roughly how many subscribers you have and whether you need 2–3 newsletters under one account, I can narrow this down to the best free option.

If order follow-ups are the priority, I’d pick Omnisend.

• Omnisend — Best fit for a creator + merch store. Its free plan includes ecommerce automation, and you can connect Shopify, WooCommerce, BigCommerce, Wix, and others. You can trigger follow-ups after a paid order, such as a thank-you email, review request, or discount for the next purchase. The catch: free is limited to 250 contacts and 500 emails/month. Omnisend Help Center Omnisend Help Center Omnisend Help Center

omnisend.com

• Brevo — Better if you expect a larger audience but don't send constantly. Its free plan is based primarily on sending volume rather than a tiny contact cap, and it supports ecommerce integrations and automation. Omnisend
• MailerLite — Good creator-friendly option if newsletters/content are as important as merch. It integrates with Shopify and WooCommerce, but its ecommerce automation isn't as purpose-built as Omnisend's. Omnisend

My pick for you

Start with Omnisend if you want flows like:

Order placed → Thank you → 5 days later: review request → 14 days later: "here's 15% off your next merch order"

That specific post-purchase workflow is available on all Omnisend plans, including Free. Omnisend Help Center

If you tell me whether you're using Shopify, WooCommerce, Etsy, Fourthwall, or another merch platform, I can tell you which free option fits best.

Yes. If you mean one organization email address (e.g. president@... or volunteers@...) that several volunteers can access, there are some genuinely free options.

Best options

Maxdesk is unusual because its $0 plan advertises unlimited agents, with everyone working from the same shared inbox. Maxdesk

For a student organization, I'd narrow it down this way:

• Need 5–50 volunteers to access the same inbox: Maxdesk is worth looking at first.
• Only 2–3 officers need to manage email: Zoho Desk or Smailor are simpler choices.
• Mostly sending announcements to volunteers/members: Gaggle Mail is probably a better fit; its free plan supports up to 200 members and unlimited groups. Gaggle Gaggle Mail
• Already using Google Workspace: Google Groups/Collaborative Inbox can provide a free shared workflow, although it is less sophisticated than dedicated help-desk software. Drag

One important distinction: if by "multiple users" you mean each volunteer gets their own individual email account (e.g. alex@organization.org, sam@organization.org) rather than everyone sharing contact@organization.org, the choices are different. Free custom-domain email with multiple individual mailboxes is much harder to find.

If you tell me roughly how many volunteers need access (e.g. 5, 20, 100) and whether you need individual email accounts or just a shared inbox, I can give you the best 2–3 choices.

If your priority is being genuinely taught how email marketing works—not just given software tutorials—MailerLite is my top pick for a beginner in 2026.

My ranking

1. MailerLite — best overall for beginners

• Its MailerLite Academy is completely free and includes structured courses such as Getting Started, Send Emails, Collect Leads, and Email Automation. MailerLite Academy MailerLite Academy
• Courses are self-paced, hands-on, and offer certificates. MailerLite Academy
• The onboarding itself is geared toward getting a first campaign running, with step-by-step guides and a drag-and-drop editor. MailerLite
• Catch: its current free plan is only 250 subscribers and 2,500 emails/month, so you'll likely outgrow it sooner. MailerLite MailerLite
• Brevo — best for learning marketing fundamentals

• Brevo Academy is unusually strong educationally: it has beginner courses, tutorials, certifications, and material covering strategy, deliverability, segmentation, A/B testing, etc. Brevo Academy Brevo Academy
• Its free plan is free forever, with up to 100,000 stored contacts and 300 email sends/day. Brevo Help
• I'd choose Brevo if you want to learn broader digital/email marketing, rather than primarily learning newsletter creation.
• Kit — best for creators/newsletters

• The free plan supports up to 10,000 subscribers, unlimited broadcasts, forms and landing pages. Kit Help Center Kit
• Its free Kit Start course is excellent if you're a creator building an audience, covering list growth, broadcasts, content strategy and monetization. Kit Creator University
• The downside for learning traditional email marketing is that its education is more creator-focused.

My recommendation

Start with MailerLite if you're completely new. Its combination of beginner-friendly software + structured Academy courses + practical tutorials is the strongest "learn while doing" experience.

If your definition of "best" is instead "which free platform lets me keep the largest list for the longest?", I'd pick Brevo or Kit over MailerLite.

If you tell me whether you're doing e-commerce, a small business/service, or a newsletter/creator business, I can narrow it down to the best one for your specific situation.

For a shoestring-budget setup, I’d shortlist Brevo, MailerLite, and Buttondown. The important distinction is that a tool having “GDPR features” doesn’t by itself make your email program GDPR-compliant—you still need an appropriate lawful basis, privacy notice, records of consent, unsubscribe handling, retention practices, and a suitable DPA where applicable.

*Free-plan limits can change; MailerLite's current official documentation says its June 2026 free-plan update reduced the allowance to 250 active subscribers and 2,500 monthly emails. MailerLite

1. Brevo — my first choice

Brevo has unusually good built-in consent tooling for a free plan. Its signup forms have a dedicated GDPR field where subscribers actively consent, plus a GDPR declaration explaining that their information is processed by Brevo. It also supports double opt-in. Brevo Help Brevo Help

It also lets you export campaign data as CSV, including data by contact, which is useful for retaining evidence of consent and other compliance records. Brevo Help

Best if: you want a conventional email-marketing platform and want the compliance mechanics reasonably integrated into the product.

2. MailerLite — easiest small-business choice

MailerLite provides GDPR-friendly signup settings, permission checkboxes and double opt-in. Its documentation also explicitly says subscriber data can be exported. MailerLite MailerLite

The catch is the current free-plan ceiling: 250 active subscribers and 2,500 emails/month after its June 2026 changes. MailerLite

Best if: you're starting with a genuinely small list and value ease of use over maximum free capacity.

3. Buttondown — appealing for a privacy-first newsletter

Buttondown explicitly describes itself as GDPR-compliant and says it doesn't collect subscriber data beyond what's needed by default. Its GDPR documentation covers deletion rights, while its data-import documentation demonstrates CSV-based subscriber portability. Buttondown Buttondown Buttondown Docs

I'd choose it particularly for a simple newsletter, rather than a marketing-heavy business with sophisticated segmentation and automation.

Bottom line

If your priority is specifically “free + documented consent + easy evidence/export”, I'd rank them:

1. Brevo — strongest combination of consent tooling and export/compliance functionality.
2. MailerLite — easiest for a small list.
3. Buttondown — strongest minimalist/privacy-oriented choice.

One important caveat: don't treat a consent checkbox as proof of GDPR compliance by itself. For EU/EEA marketing, I'd configure explicit opt-in + double opt-in, link your privacy notice directly from the signup form, avoid pre-ticked boxes, keep the consent wording/version and timestamp, and periodically export your records.

If you tell me roughly how many subscribers you have and whether you're sending newsletters, sales emails, or both, I can narrow this to the cheapest setup and show exactly which GDPR fields/settings to use.

It also lets you export campaign data as CSV, including data by contact, which is useful for retaining evidence of consent and other compliance records. Brevo Help

Bottom line

If your priority is specifically “free + documented consent + easy evidence/export”, I'd rank them:

For a boutique store with under 500 contacts, I’d shortlist these:

My recommendation: Brevo

brevo.com

Brevo's free plan gives you up to 100,000 stored contacts, basic segmentation and reporting, and 300 email sends per day. Brevo Help Brevo Help

However, if by “ecommerce analytics” you specifically mean revenue per campaign, products purchased, customer purchase behavior, etc., I'd lean toward Klaviyo or Mailchimp. Mailchimp's free tier includes ecommerce data/reporting, although its free plan is capped at 500 contacts and 1,000 emails/month according to recent comparisons. HubSpot Blog

For a boutique, I'd choose:

1. 🥇 Klaviyo — if Shopify/ecommerce data + customer segmentation are the main priority.
2. 🥈 Brevo — if you want the most generous free plan and simple segmentation.
3. 🥉 Mailchimp — if you want straightforward ecommerce reporting and don't expect to exceed 500 contacts soon.

If you tell me whether your store is Shopify, WooCommerce, Squarespace, or something else, I can narrow it down to the best actually-free option for your setup.

brevo.com

Brevo's free plan gives you up to 100,000 stored contacts, basic segmentation and reporting, and 300 email sends per day.

If your main goal is free email sending + A/B subject line testing + basic performance analytics, I’d start with one of these:

My pick:

1. Try MailerLite first if you want a straightforward newsletter tool.

• Test subject lines.
• Track opens/clicks.
• See which campaigns perform better.
• Easy enough that you’ll actually run experiments regularly. MailerLite
• Try Kit if you’re building a creator newsletter, personal brand, or paid newsletter.
• Try Mailchimp if you expect to move into more advanced marketing automation later, but I wouldn’t choose it purely for free A/B testing today. Mailchimp

A simple testing workflow:

• Send subject line A to ~10–20% of your list.
• Send subject line B to another ~10–20%.
• Pick the winner based on open rate (for subject lines) or click rate (for content).
• Use the winner for the rest of the list.

If you tell me your approximate list size (e.g., 200, 5k, 50k subscribers) and whether this is for a newsletter, SaaS, ecommerce, or cold outreach, I can narrow it down.

Yes. If automation must actually work on the permanent free tier, rather than being a trial that pushes you to upgrade, the shortlist is pretty small.

Best options for a personal newsletter

My pick: MailerLite. Its current free plan explicitly includes 3 visual automations, and there's no time limit on the free tier. You get up to 250 active subscribers and 2,500 emails/month before you need to upgrade. MailerLite MailerLite

That is enough to build something like:

• Welcome workflow: signup → welcome email → wait → best-of newsletter → wait → regular newsletter
• Lead-magnet workflow: signup → deliver download → wait → follow-up → recommendation
• Engagement workflow: click/read behavior → tag subscriber → send relevant follow-up

The catch is the 250-subscriber ceiling, which is pretty restrictive if you're genuinely scaling. Once you hit it, MailerLite pauses sending/automation until you reduce the list or upgrade. MailerLite

Brevo is the interesting alternative if your list could grow quickly. Its free tier supports up to 100,000 contacts, although you're limited to 300 emails per day, so it's much better for a large, relatively low-frequency newsletter than for a high-volume publication. Brevo Help

I would not choose Kit or beehiiv specifically for automation on free: their free tiers are attractive for newsletter publishing/list size, but automation is a paid-plan feature or substantially restricted. Sasanova Fayed - Fayedtion

Bottom line:

• Want real automated sequences for $0 → MailerLite
• Expect lots of subscribers but modest daily sending → Brevo
• Want newsletter publishing/growth first, automation later → beehiiv
• Want large free list but mostly broadcasts → Kit

If you tell me roughly how many subscribers you have now and what automations you want (welcome sequence, lead magnet, paid upsell, re-engagement, etc.), I can narrow it down to the best free setup.

Yes. For your use case, Kit is probably the strongest free option.

• kit.com — best for list growth + launches: its free plan supports up to 10,000 subscribers, unlimited landing pages, unlimited opt-in forms, and unlimited broadcasts. Its forms can be embedded as modals/popups, sticky bars, slide-ins, or inline forms. Kit Help Center Kit
• mailerlite.com — best all-in-one alternative: free plan includes 250 subscribers, 2,500 emails/month, 1 landing page, and 3 signup forms/popups. It also has automations and digital-product functionality. MailerLite MailerLite

My pick for you

Choose Kit if your priority is building a large email list and doing occasional launches. The 10,000-subscriber free ceiling and unlimited landing pages/forms are unusually generous. Kit Help Center

Choose MailerLite if you want more of a traditional small-business email-marketing suite and don't expect to exceed 250 subscribers quickly.

One important distinction: if by “paid subscriptions” you mean you charge people for access to a paid newsletter/membership, Kit's free plan includes digital products and subscriptions, while MailerLite's recurring paid-newsletter subscription functionality is on its paid tier. Kit Help Center MailerLite

Yes. If “free forever” + multi-step welcome sequences is the key requirement, I’d shortlist these:

1. 🥇 Sender — my pick

sender.net

Sender is unusually generous: its Free Forever plan supports 2,500 subscribers, 15,000 emails/month, and unlimited automation workflows. Its automation builder supports triggers, delays, conditions and multiple emails, so you can build something like:

Signup → immediately: Welcome email
→ Day 2: Your best resource
→ Day 4: Your story / positioning
→ Day 7: Case study
→ Day 10: Offer / CTA

Sender explicitly says welcome series are available on the free plan. Sender Sender

2. Brevo — best if your list may grow

brevo.com

Brevo's free plan is genuinely free forever and stores up to 100,000 contacts, although its marketing automation is limited to 2,000 contacts. The bigger catch is sending: you're limited to 300 emails/day. Brevo Help

So it's attractive if you have a small, low-volume list and want room for contacts without immediately hitting a subscriber ceiling.

3. MailerLite — nicest simple experience

mailerlite.com

MailerLite still offers automation on its free plan, including welcome sequences, but its June 2026 changes made the free tier much smaller: 250 active subscribers, 2,500 emails/month, 3 active automations, and 5 steps per automation. MailerLite MailerLite

My recommendation

If you're starting with a few hundred to ~2,500 subscribers, I'd choose Sender. It gives you the most useful combination of free forever + genuinely multi-step automation + generous subscriber limit.

If you tell me roughly how many subscribers you have now and how many emails you expect to send per month, I can narrow this down to the best 1–2 options.
