MailerLite

MailerLite review: the easiest serious email tool, with a smaller free plan

MailerLite is an email marketing platform built for small businesses, creators and lean marketing teams. You collect subscribers with forms, pop-ups and landing pages, write newsletters in a drag & drop editor, and run welcome series, nurture flows and abandoned-cart sequences in a visual automation builder. Around that core it adds websites, paid newsletters, digital products and bookings, plus an MCP server so AI assistants like Claude, ChatGPT and Gemini can manage campaigns and subscribers for you.

Our current 361 score is 8.2/10. The product is the easiest genuinely capable email tool we have used — 9.0 for ease of use — and its paid pricing is fair. What holds the score back is commercial, not technical: the free plan shrank to 250 subscribers, the cheaper Comfort plan carries a send cap, and the compliance gate that keeps deliverability high also blocks some legitimate new accounts.

What changed in 2026: Free, Comfort and Power

MailerLite now sells three self-serve plans plus Enterprise. The old Growing Business and Advanced plans became Comfort and Power, and the free plan was cut back hard.

• Free — $0, up to 250 subscribers and 2,500 emails a month, 3 automations of up to 5 steps, 1 website and 1 landing page, 3 forms, 2 user seats, knowledge-base support only.
• Comfort — from $12/month ($10.80 billed yearly) for 500 subscribers. Monthly sends are capped at 10x your subscriber tier, with 50 automations, 10 sites, 10 forms, 5 digital products, 3 seats, email support and the MailerLite logo removed.
• Power — from $25/month ($22.50 billed yearly) for 500 subscribers. Unlimited monthly emails, automations, sites, forms, digital products and seats, multiple automation triggers, and live chat plus email support.
• Enterprise — custom pricing above 200,000 subscribers, with a dedicated IP, deliverability support and onboarding.

Every paid plan includes a 14-day free trial without a credit card, and annual billing saves 10%. Prices step up with each subscriber bracket: at 2,500 subscribers Comfort is $33 and Power $49 a month; at 10,000 it is $89 versus $129.

Core capabilities

• Newsletter editor — drag & drop blocks, a plain-text editor, custom HTML, reusable templates and a free stock image library.
• Automations — visual builder with templates, e-commerce triggers, RSS campaigns and auto-resend to non-openers.
• Audience tools — groups (tags), dynamic segments, preference centers and individual subscriber profiles.
• Growth — embedded forms, pop-ups, promotion pop-ups, form A/B tests and an iPad app for offline signups.
• Sites — landing pages and full websites with templates and an AI landing page builder.
• Commerce — sell digital products, paid newsletters and bookings without a separate checkout tool.
• HeyLite intelligence — AI writing assistant, subject line generator, smart sending and campaign insights.
• MCP & API — connect Claude, ChatGPT, Gemini or your own agents, plus 100+ integrations.

Deliverability and the approval gate

MailerLite is consistently placed near the top of independent inbox-placement tests, and the reason is not magic infrastructure. It is policing. New accounts go through an approval review of your website and signup method, and accounts that cross complaint, bounce or unsubscribe thresholds are paused automatically. Clean senders benefit from a shared reputation that stays clean.

The cost of that policy falls on new users. A missing website, a free email domain as sender, or an imported list with old contacts is enough to stall approval or trigger a pause after the first campaign. This is the most common complaint in public reviews. Authenticate your domain, publish a real website with a visible signup form, and never import a list you cannot prove opted in.

Where MailerLite wins

• Learning curve: a first campaign, form and welcome automation takes an afternoon, not a week.
• Price at small and mid list sizes: Comfort at $12 for 500 subscribers undercuts most comparable tools.
• Breadth for the money: sites, forms, digital products and bookings are included rather than upsold.
• Deliverability on clean, opt-in lists.
• AI readiness: an official MCP server means your assistant can draft, segment and report without copy-paste.

Where it falls short

• The free plan is now a sandbox: 250 subscribers and 2,500 sends run out fast.
• Comfort's 10x send cap punishes frequent senders — a daily newsletter needs Power.
• Strict approval and automated suspension can block a legitimate sender with an older list.
• E-commerce depth trails Klaviyo for revenue-based segmentation and predictive analytics.
• No SMS channel, so stores that want email and SMS together need a second tool.

How to test MailerLite properly in 14 days

1. Set up your sending domain with SPF, DKIM and DMARC before you import anyone.
2. Start the Power trial even if you expect to buy Comfort — you will see which limits you actually hit.
3. Import only contacts that opted in recently; leave older segments out until you have sending history.
4. Build a welcome automation and one landing page, then send two real campaigns.
5. Count your monthly sends per subscriber. If it is above 10, budget for Power.
6. Compare open and click rates with your current tool on the same audience before migrating the full list.

Final verdict

MailerLite is the right pick for a small business, creator or lean team with an opt-in list who wants newsletters, automations and landing pages in one clean tool at a fair price. It is the wrong pick for cold outreach, for large stores that live on revenue segmentation and SMS, or for anyone hoping to stay free beyond 250 subscribers. Run the trial on Power, measure your send frequency, then choose between Comfort and Power on that number.
