What "Free" Actually Means in Email Marketing
Every platform in this space offers a free tier. Most of them are designed to be just good enough to get you hooked, then limited enough to push you toward a paid plan. The difference between a genuinely useful free tier and a glorified trial is in the caps — contacts, sends, and features.
The four limits that matter: how many contacts you can store, how many emails you can send per month, what automation features are included, and whether they slap their branding on your emails. Some free tiers are sustainable for small senders. Others are trial runs with a deadline disguised as a free plan.
Here's the honest breakdown of all nine — ranked by how much they actually give you.
1. Brevo — Most Generous Free Tier by Volume
Free: 300 emails/day — unlimited contacts
Most generous free tier. No contact limit — you can store as many subscribers as you want. The catch is 300 emails/day (roughly 9,000/month), which is real volume for a small sender. Transactional emails, automation, and a landing page builder are all included. Brevo's free plan is the one that makes competitors look stingy.
2. beehiiv — Best Free Newsletter Platform
Free: up to 2,500 subscribers — no logo on emails
Best free newsletter platform. No beehiiv logo on your emails — that alone separates it from most free tiers. Up to 2,500 subscribers on the free plan, with a clean writing interface and a web archive for each issue. Built specifically for newsletters, not retrofitted. If you're starting a newsletter in 2026, this is where to start.
3. ConvertKit — Best Free Tier for Creators
Free: unlimited subscribers — basic features
Best free tier for creators. Unlimited subscribers on the free plan — no contact cap. You lose automation sequences and some segmentation features, but you can grow your list without paying for the privilege. If you're building an audience before you have a product to sell, this is the right starting point. Sends are also unlimited.
4. MailerLite — Best Free UI
Free: 1,000 subscribers / 12,000 emails/mo
Best free UI. Clean, simple, no credit card required to start. The drag-and-drop editor on the free plan is better than what most paid platforms offer. 1,000 subscribers and 12,000 emails/month is a real working limit for a small business. Automation is available on the free tier — limited to one workflow, but it's there. Worth using if UI friction is what's slowing you down.
5. Systeme.io — Most Generous All-in-One Free Plan
Free: 2,000 contacts — funnel builder, email, automation
Most generous all-in-one free plan. 2,000 contacts with funnel building, email automation, a course platform, and affiliate management — all included at $0. It's not just an email tool; it's an attempt to replace a stack of paid software. The free tier is legitimately functional. If you're selling something online and have no budget, Systeme.io is the most you can get for nothing.
6. GetResponse — Free Plan With Landing Pages
Free: 500 contacts — email + landing pages
Free plan includes landing pages too — which puts it ahead of tools that gate that feature. 500 contacts is a low cap, but the free plan is a genuine on-ramp to one of the stronger mid-market email platforms. If you're going to outgrow the free tier and want a platform with serious automation and AI features on the paid plan, starting here makes sense.
7. HubSpot — Free CRM With Email Included
Free CRM forever — email marketing included
Free CRM with email included. HubSpot's free tier is genuinely broad — contacts, deals, email, forms, and basic automation all exist at $0. The email send limits are tight (2,000/month) and HubSpot branding is on your emails. Worth it if you need a CRM more than a dedicated email platform. If email is your primary channel, the other options here give you more.
8. Mailchimp — The Famous One (Diminished)
Free: 500 contacts / 1,000 emails/mo
The famous one. The free tier got gutted — it was better before 2023. 500 contacts and 1,000 emails/month is hard to work with, and they cut automation from the free plan. Mailchimp's brand recognition still sends people here first, but there's no reason to choose it over Brevo, MailerLite, or beehiiv if you're starting from scratch on a budget. It's not bad software — it's just a bad free tier.
9. Moosend — Best Paid Trial
30-day free trial — then $9/mo
30-day free trial, then $9/mo. Moosend doesn't have a permanent free tier — this is an honest trial with a clock on it. It earns a spot here because the paid plan starts low and the trial is genuinely full-featured. If you're evaluating affordable paid tools, the 30 days is enough time to make a real decision. Don't confuse it with a free forever option.
How to Pick
What you're doing determines which free tier is worth your time:
beehiiv — no logo on emails, clean writing experience, 2,500 subscribers free.
ConvertKit — unlimited subscribers, no contact cap, pay when you need automation.
Brevo — 300 emails/day with no contact limit is the best raw volume you'll find at $0.
MailerLite — best editor on a free plan, no card required, automation included.
Systeme.io — 2,000 contacts with funnels, automation, and a course platform all free.
The Honest Ceiling
Free tiers are starting points — designed to be outgrown. The ones above are genuinely useful for small senders, early-stage businesses, and side projects. But once you're past a few thousand subscribers or you need real automation, segmentation, and deliverability tools, you'll pay for it.
The good news: most of these platforms keep paid plans under $20/month at the entry level. The move from free to paid isn't expensive — it's just a decision you should make intentionally, not because a cap wall forced you into it.
Pick the free tier that fits what you're building now. Migrate when you have the revenue to justify it.
