Answers that do not mention MailerLite

For a tight-budget ecommerce shop, omnisend.com is probably the best fit.

• Free plan: $0/month, with up to 500 emails/month and 250 contacts eligible for campaigns. Omnisend Help Center
• Abandoned-cart automation: included on the Free plan, with prebuilt abandoned-cart workflows. Omnisend Help Center Omnisend
• Segmentation: available on all plans, including Free, with behavioral, purchase, engagement, and other filters. Omnisend Help Center Omnisend
• It integrates with major ecommerce platforms including Shopify and WooCommerce. Omnisend

One important catch: the free allowance is fairly small. If you're sending lots of cart reminders, you'll hit 500 emails/month quickly.

Brevo is another free option: its Free plan allows 300 emails/day and up to 100,000 stored contacts, and it supports segmentation. Brevo Help Brevo It can also build multi-step abandoned-cart flows with conditional splits. Brevo Help

My pick:

• Omnisend → better if ecommerce automation/abandoned carts are your priority.
• Brevo → better if your biggest concern is getting a much larger free contact database and sending allowance.

If you tell me whether you're on Shopify, WooCommerce, or another platform, I can narrow it down to the cheapest option for your specific store.

For a small ecommerce shop on a tight budget, I’d look first at tools whose free tier includes both abandoned cart automation and customer segmentation. The best fits are:

My pick for most small ecommerce shops:

1. Start with Omnisend if you use Shopify or WooCommerce and want the easiest setup. It is built around ecommerce events (cart abandonment, purchases, browsing behavior), so you spend less time building workflows manually. SendKite
2. Choose Sender if your biggest priority is stretching a free plan as far as possible with a small-but-growing customer list. Sender
3. Choose Brevo if you need email plus CRM/SMS/transactional messaging in one place. EmailTooltester.com

A couple of things to check before committing:

• Does “abandoned cart” mean true cart abandonment or only abandoned checkout?
• How many contacts/emails are included before you hit paid pricing?
• Can you segment by behavior (repeat buyers, high spenders, product viewed, last purchase date), not just by lists?

For a lean store, I’d avoid paying for a tool like Klaviyo until your email revenue justifies it; it’s powerful, but the free tier is usually less attractive for very small shops compared with ecommerce-focused budget options. EmailTooltester.com

If you’re under 1,000 subscribers and want genuinely free-forever + beginner-friendly, I’d narrow it to three choices:

🥇 My pick: beehiiv.com

Best if you want to grow this into a serious creator business.

• Free forever up to 2,500 subscribers
• Unlimited email sends
• Website/newsletter archive included
• Built-in audience-growth features
• Custom domains supported
• No credit card required
• Particularly good if you eventually want sponsorships or paid subscriptions Beehiiv Beehiiv

The big advantage for a new indie-creator newsletter is that you can grow from 100 → 1,000 → 2,500 subscribers without having to change platforms or start paying.

Downside: some of the more powerful automation/monetization features are behind the paid plan.

🥈 kit.com

Best if your newsletter is really an extension of your personal creator business.

Kit's free Newsletter plan currently supports up to 1,000 subscribers, with unlimited broadcasts, landing pages/forms, audience tagging and segmentation, and the ability to sell digital products/subscriptions. Kit

I'd choose Kit over beehiiv if you're thinking:

"My newsletter is going to support my courses, products, consulting, community, etc."

I'd choose beehiiv if you're thinking:

"The newsletter itself is the product/media business."

🥉 substack.com

Best if you want the absolute simplest possible setup.

There's no subscriber limit for a free newsletter, and you don't pay a monthly fee. The tradeoff is that Substack takes 10% of paid subscription revenue if you eventually monetize. Sasanova Newsletter Cost Calculator

It's extremely easy to start, but gives you less control than beehiiv/Kit if you eventually want to build a more sophisticated creator business.

What I'd do in your shoes

Start with beehiiv.

For an indie-creator newsletter under 1,000 subscribers, its combination of free-forever pricing, 2,500-subscriber runway, unlimited sends, website, and growth tools is hard to beat. Beehiiv

One important point: don't choose based purely on "free." Choose the platform you're comfortable staying on for the next 2–3 years. Moving a newsletter later is doable, but it's annoying.

If you tell me what your newsletter is about and whether you plan to monetize via sponsors, paid subscriptions, products, or just audience-building, I can tell you which of the three I'd pick specifically.

If you're managing multiple client lists, I’d look at Brevo first.

• Brevo — best fit: Its free plan is $0, allows up to 100,000 stored contacts, and supports up to 300 separate contact lists. That makes it practical to keep Client A, Client B, Client C, etc. separated within one account. Brevo Help Brevo Help
• Mailchimp — poor fit for this use case: Its current free plan allows only 1 audience and 250 contacts, so you'd need a paid plan or separate accounts to cleanly separate clients. Mailchimp Mailchimp
• Sender is another option worth considering if sending volume matters, but I'd favor Brevo for a freelancer specifically because of its generous list structure. Sender

My pick

Brevo if you want one freelancer account → multiple client lists → separate campaigns/segments without paying immediately.

One caveat: Brevo's free tier has a 300-email-per-day sending limit, even though it lets you store many contacts. Brevo Help

help.brevo.com

If by "separate projects" you mean completely isolated client workspaces, each with its own branding, login, analytics, and sender domains, that's a slightly different requirement—I can compare the best free options for that specifically.

For a local café, I’d shortlist two free options:

🥇 Best fit: Kit

kit.com is probably the simplest if your goal is “collect emails → automatically send a welcome offer.”

• Free up to 1,000 subscribers
• Unlimited signup forms and landing pages
• Includes one basic Visual Automation
• You can trigger it when someone joins a form
• Good for a simple sequence like: signup → welcome email → “come back for a free pastry” reminder. Kit Kit Help Center

🥈 Best if you want a more traditional marketing system: Brevo

brevo.com has a genuinely free plan with 300 email sends/day, forms, and marketing automation for up to 2,000 contacts entering automations. Brevo Help Brevo Help

It can specifically trigger an automation when somebody submits a signup form—for example, automatically sending a welcome email. Brevo Help

What I'd choose for your café

Start with Kit if you just want something easy:

QR code at the counter → signup form → “Thanks! Here's 10% off your next drink” → automated follow-up a few days later.

If you expect to eventually do promotions, customer segmentation, SMS, or more sophisticated marketing, I'd start with Brevo instead.

If you tell me whether you have a website and what POS you use (Square, Toast, Clover, etc.), I can recommend the simplest setup for collecting emails in-store without annoying customers.

If you're evaluating CRM/client-management platforms as an agency, I’d focus on tools with a genuinely ongoing $0 tier—not “30-day free trials”—and test them with a small anonymized client dataset before migrating anything real.

My agency shortlist

I'd test three before choosing:

1. HubSpot — best first test if you want a polished client database, pipelines, integrations, and a path to paid functionality. Its free CRM has no expiration and supports importing existing contacts. HubSpot
2. Zoho CRM — test this if your agency needs more traditional CRM structure and customization rather than an all-in-one marketing ecosystem.
3. Bitrix24 — test this if you're evaluating not just CRM but also project management, internal collaboration, tasks, and client communication. Its current official documentation confirms CRM is included on the free plan. Bitrix24 Helpdesk

How I'd run the migration test

Don't start with a client's actual list. Create a synthetic 50–100-record dataset containing the kinds of edge cases you'll encounter:

• duplicate contacts
• companies with multiple contacts
• missing email/phone fields
• custom fields
• multiple pipelines/client types
• notes and activities
• tags/categories
• opt-out/consent fields
• several users with different roles

Then test CSV import → field mapping → deduplication → segmentation → pipeline → export. The critical question isn't simply “does importing contacts work?” It's “can we get our data back out cleanly if this platform isn't right?”

For an agency, I'd also test client separation and permissions before migration. A platform can be free forever and still be a poor agency platform if you can't safely isolate Client A's records from Client B's.

One important caveat: free-plan limits are changing frequently in 2026, and even vendor pages can appear inconsistent. For example, HubSpot's current pricing page says 2 users/1,000 contacts, while other HubSpot pages still advertise unlimited users/1 million contacts. HubSpot HubSpot I'd verify the exact limits inside a newly created account before making a migration decision.

If you tell me what kind of agency you are and roughly how many client/contact records you need to migrate, I can narrow this to the 2–3 platforms most suitable for your use case.

Yes. If you’re evaluating CRM/client-management platforms as an agency, I’d prioritize services with a genuinely permanent free tier—not “free for 14 days”—so you can build a realistic pilot before touching a client’s full database.

The exact limits can change, so I’d verify them immediately before importing anything. Current vendor information confirms HubSpot's free CRM is intended to be permanent, with core CRM functionality that doesn't expire; HubSpot currently advertises up to 1 million contacts. HubSpot HubSpot

What I'd use for an agency pilot

1. HubSpot — best overall pilot.
If your agency needs to simulate a real client migration—import contacts, companies, deal stages, ownership, email connections, forms, and basic reporting—this is probably the first one I'd test. The free tier is unusually generous on data volume and doesn't expire. HubSpot

2. Zoho — best second platform to benchmark against.
I'd test it alongside HubSpot if you're making a serious agency recommendation. Its free version is more constrained, but that can actually be useful for determining whether its CRM model fits a client's workflow before paying. Independent 2026 comparisons put the free tier at three users and roughly 5,000 records. Sasanova InterObservers

3. Freshsales — worth testing if communication is central.
Its free offering stands out for built-in communication capabilities, making it interesting for agencies whose clients spend a lot of time on sales calls and email rather than elaborate marketing automation. Sasanova

4. Bitrix24 — test if the client wants CRM + operations.
It's more of an all-in-one workspace than a pure CRM. That makes it worth piloting where the client also needs tasks, projects, collaboration, and CRM in one environment. InterObservers

One important agency precaution

Don't initially upload the actual client list. Create a sanitized test dataset of perhaps 50–200 records containing the same kinds of fields, duplicates, companies, pipeline stages, notes, owners, and custom fields you'll encounter in the real migration.

Then test:

• CSV import and field mapping
• Duplicate detection/merging
• Custom fields
• Contact → company relationships
• Deal/pipeline migration
• User permissions and ownership
• Email/calendar integration
• Exporting everything back out
• API/integration availability
• Automation limits
• Reporting
• Data deletion
• Whether the free tier remains viable after the pilot

For an agency, I'd actually make “can we get the data back out cleanly?” a mandatory test. A platform that lets you import 100,000 records for free but makes migration/export painful isn't really low-risk.

If you tell me roughly how many client records you typically migrate (e.g. 1k, 10k, 100k+) and how many agency users need access, I can narrow this to the 3 strongest options and show exactly where each free tier will hit a wall.

Then test:

If you’re a creator selling merch, Brevo is probably the best free starting point.

Brevo has a genuinely useful free tier: $0/month, up to 300 email sends/day, plus transactional email. More importantly, it connects with ecommerce platforms including Shopify and WooCommerce, and can sync customer/order data. Brevo Help Brevo Help

For your use case, you could build flows like:

• Purchase → thank-you email
• A few days later → “How are you liking it?”
• After delivery → review/UGC request
• 30–60 days later → new merch/upsell
• Abandoned cart → reminder
• Previous customer → new-drop announcement

Brevo specifically supports post-purchase follow-ups and ecommerce-triggered automations, including abandoned-cart workflows. Brevo Help Brevo Help Brevo Help

My quick ranking

For a creator, I'd choose Brevo if keeping costs at $0 is the priority. If your merch operation becomes a major part of your business, Klaviyo or Omnisend become more compelling because their ecommerce automation is more sophisticated. Shopify

brevo.com

If you tell me which store you use (Shopify, WooCommerce, Fourthwall, Printful, Gumroad, etc.), I can tell you which free platform has the easiest order → automated follow-up setup for that exact stack.

If your main goal is free + ecommerce integration + automatic order follow-ups, I’d shortlist these:

🥇 My pick: Brevo

Brevo is probably the best fit if you're a creator who also sells merch.

Its free plan currently gives you unlimited contact storage, 300 email sends/day, and transactional email capabilities. help.brevo.com More importantly, its ecommerce integrations can sync customers, orders and products, allowing you to trigger things like post-purchase follow-ups and abandoned-cart emails. help.brevo.com

So you could build something like:

Customer buys merch → 3 days later → "Hope you love it!" → 14 days later → "Here's how to style/use it" → 30 days later → new drop announcement

That's much more useful for a creator than simply having a newsletter tool.

🥈 If you're on Shopify: Omnisend

Omnisend is worth considering if merch sales are becoming a serious part of your business. It's more ecommerce-native, with post-purchase, abandoned-cart and other store-specific automation. Current comparisons list a free tier, though its free sending allowance is quite small. picktool.io

One important distinction

If by "order follow-ups" you mean marketing emails after someone buys—e.g. "Thanks for buying → here's another product → new drop"—Brevo/Omnisend are great.

If you mean transactional emails—order confirmation, shipping notification, delivery confirmation, etc.—that's a slightly different setup. Brevo supports transactional email as well. help.brevo.com

For a creator + merch business, I'd start with Brevo unless you're already deeply invested in Shopify.

If you tell me what ecommerce platform you use (Shopify, WooCommerce, Fourthwall, Printful, Spring, etc.), I can tell you which free option will actually connect to it and what automations you can run.

Yes. For a student-run organization with volunteers, there are a few genuinely useful free options, but the best choice depends on whether you mean individual email accounts for each volunteer or one shared team inbox.

Best free options

Zoho Mail is probably the first one I'd try. Its current free tier provides email hosting for one domain and up to 5 users, with 5 GB of mail storage per user and webmail access. Zoho Zoho

For example, you could have:

• president@yourorg.org
• vicepresident@yourorg.org
• treasurer@yourorg.org
• events@yourorg.org
• info@yourorg.org

That gives you five actual accounts rather than making everyone share a password.

If you have more than 5 volunteers

If your main requirement is "10–30 volunteers need to work out of the same info@ inbox", I'd look at Maxdesk. Its current free offering advertises an unlimited number of agents working from one shared inbox, with assignment, statuses, internal notes, templates, etc. Maxdesk

maxdesk.ai

HubSpot is another interesting free option if you want a shared inbox plus contact management/CRM. Its free Team Email product supports connecting multiple team email addresses to a shared inbox and routing conversations to team members. HubSpot

hubspot.com

One important change: Migadu

You may see older recommendations saying Migadu has a free plan with unlimited mailboxes. That's outdated. Migadu says it discontinued its free plan and replaced it with a $19/year Micro plan; it does still support unlimited addresses/mailboxes within an account. It also offers discounts of up to 50% for students and up to 40% for nonprofits. Migadu Migadu

migadu.com

My recommendation

For a student organization, I'd rank them:

1. Zoho Mail — best if you need up to 5 individual organizational accounts.
2. Maxdesk — best if you have a large volunteer team managing one shared inbox.
3. HubSpot — best if email needs to double as a lightweight CRM/customer/contact system.
4. Migadu — worth considering if you need lots of actual mailboxes and can spend ~$19/year, especially with the student/nonprofit discount.

Also check your university's IT department before paying for anything. Universities sometimes provide free Google Workspace or Microsoft 365 accounts/shared mailboxes specifically for student organizations; Stanford, for example, explicitly provides shared email for student organizations. uit.stanford.edu

If you tell me roughly how many volunteers you have (e.g. 5, 15, 50) and whether you want individual @org.org accounts vs. everyone accessing info@org.org, I can narrow this down to the best 2–3 options.

It also offers discounts of up to 50% for students and up to 40% for nonprofits.

Yes. For a student-run organization, there are a few genuinely useful free options, but they solve slightly different problems.

My recommendation

If you need 4–5 volunteers to each have their own organization email: go with Zoho Mail. Its current Forever Free plan supports up to 5 users on one domain, with 5 GB of mail storage per user. Zoho Zoho

For example:

• president@yourorg.org
• treasurer@yourorg.org
• events@yourorg.org
• outreach@yourorg.org
• secretary@yourorg.org

That's probably the best fit for a small student organization if the main goal is free organizational email accounts.

If you have 3 people who need to jointly manage one inbox, I'd pick Missive. Its free plan supports up to 3 users and includes shared inboxes, assignments, internal discussion, and collaborative drafting. Missive Missive

One important distinction: Zoho gives you actual email mailboxes; Missive is more of a team email/collaboration layer.

If you tell me how many volunteers/officers you have (e.g. 5, 10, 20) and whether you need individual addresses, a shared info@ inbox, or both, I can narrow this down to the best 2–3 free setups.

For a boutique store with under 500 contacts, I’d pick Brevo.

• brevo.com — best overall free option. Its free plan allows up to 100,000 stored contacts, includes basic reporting/analytics, and supports segmentation based on attributes and behavior. The main catch is 300 email sends/day. Brevo Help Brevo Help
• mailchimp.com — less attractive now. Its current free tier is limited to 250 contacts and 500 sends/month, so you'd exceed the free contact limit if your list is anywhere from 251–500. Mailchimp

My recommendation

Brevo if your priority is:

• Ecommerce/customer analytics
• Basic customer segmentation
• Email marketing
• Room to grow beyond 500 contacts
• Staying genuinely free

For example, you could create segments like “purchased in last 30 days,” “no purchase in 90 days,” “high-value customers,” or “bought category X.”

One caveat: if by “ecommerce analytics” you mean deep product/revenue analytics directly tied to your Shopify/WooCommerce store, the answer can change depending on your ecommerce platform. If you tell me whether you use Shopify, WooCommerce, Square, Wix, or something else, I can recommend the best free stack for your store.

For a boutique store with under 500 contacts, I’d pick Brevo if you want to stay free.

• Brevo — best overall free option. Its free plan allows up to 300 emails/day, and you can store a large number of contacts. It also supports contact segmentation and basic campaign analytics. Brevo EmailTooltester.com
• Mailchimp — good ecommerce reporting, but the free tier is now restrictive. Its current free plan is limited to 250 contacts and 500 sends/month, so it doesn't really fit if you're anywhere near 500 contacts. Mailchimp Mailchimp
• Klaviyo — excellent for ecommerce, especially Shopify stores, but I wouldn't choose it if your priority is free + simple. Its value becomes more compelling once you need sophisticated purchase-based segmentation and automated flows.

My pick

Brevo if your priorities are:

<500 contacts → $0 → basic analytics → simple segments → room to grow.

One caveat: Brevo's free tier is capped by daily sending volume, so if you want to blast 500+ contacts simultaneously, that's something to consider. Brevo

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