MailerLite review

MailerLite is email marketing and automation software built around a drag-and-drop campaign editor, automation workflows, landing pages, websites, and signup forms. It layers in AI features: a writing assistant inside the editor, AI-powered A/B testing, and an MCP server that lets tools like ChatGPT or Claude manage email marketing through prompts, according to the product page. It also supports selling digital products and running paid newsletters, so creators can monetize a list without bolting on a separate payments tool.

The homepage claims 1M+ creators and businesses use the platform. Pricing runs from a Free plan through two paid tiers (Comfort and Power) up to a custom Enterprise plan, plus a 14-day free trial on paid plans, per the pricing page.

MailerLite's paid tiers are built to scale with you rather than forcing an early upgrade to a much pricier plan. According to the pricing page:

• The Free plan includes 250 subscribers, 2,500 monthly emails, 3 automations, 1 website, 1 landing page, 3 forms, and 1 digital product or booking.
• Comfort starts at $10.80/month (billed annually) for 500 subscribers, with 50 automations, 10 forms, 10 sites, 5 digital products, and 3 user seats.
• Power starts at $22.50/month (billed annually) for 500 subscribers and removes most caps: unlimited automations, forms, sites, digital products, and user seats, plus unlimited monthly emails under a fair-use policy.

The AI writing assistant and AI-powered A/B testing are built into the same editor rather than sold as an add-on, and the MCP server for ChatGPT/Claude is a feature competitors in this price range generally don't list. Bundling landing pages, websites, forms, and digital-product sales into the core plans also means smaller senders don't need a second tool just to collect leads or sell an ebook.

The Free plan's subscriber cap was cut from 1,000 to 500, according to one Reddit thread where a user who'd just migrated their list got notified of the change mid-setup. One commenter summed up the reaction: "they have lost a customer". Free-tier users also only get knowledge-base support, per the pricing page — no email or chat access until you pay.

MailerLite enforces strict anti-spam thresholds that can trigger account suspension: more than 0.2% spam complaints, 5% bounces, 1% unsubscribes, or under 3% open rate, per the company's anti-spam policy quoted in a Reddit thread. In that thread, a startup reported its account was shut down after a single send to roughly 7,000 addresses, with commenters pressing on whether the list was properly opted-in and double-verified before the blast — a reminder that MailerLite polices list hygiene aggressively rather than just flagging it.

Plan prices also scale with subscriber count, so the $10.80 and $22.50 starting prices only apply at the smallest tier; costs climb as your list grows, and Enterprise pricing above 200K subscribers isn't published.

MailerLite's Free plan covers 250 subscribers and 2,500 emails a month, with only 3 automations and 1 landing page — fine for testing, not for running a real list.

The real jump is Comfort to Power. Comfort starts at $12/month billed monthly or $10.80 annually for 500 subscribers, but caps monthly sends at 10x your subscriber tier (5,000 emails at 500 subs) and limits you to 50 automations and 10 forms. Power starts at $25/month ($22.50 annual) for the same 500-subscriber base but removes the sending cap entirely (fair use still applies) and unlocks unlimited automations, forms, sites, and user seats.

Both Comfort and Power scale price with subscriber count up to 200K, after which you need an Enterprise quote — pricing not published. The pricing page doesn't list a dedicated IP cost either; that's an Enterprise add-on with price on request. If you're serious about automations or multiple team members, budget for Power, not Comfort.

MailerLite supports CSV import for subscriber lists, which covers most migrations from other email tools. The bigger friction is rebuilding automations and templates — these don't transfer between platforms and have to be recreated manually, per the docs.

List quality matters more than usual here. Free and Comfort plans cap monthly sends at a multiple of your subscriber count, so an unverified or purchased list can blow through limits fast or trigger deliverability flags. Businesses migrating a messy list should clean it before import, not after.

Exporting out of MailerLite is more straightforward: subscriber data, forms, and basic campaign content can be pulled via CSV or the API. Landing pages and website builds are platform-specific and won't migrate elsewhere, which is the main lock-in risk if you've built out MailerLite's site tools.

There's no phone support on any plan, including Power, so switching teams that expect a support line should factor that into the decision before signing an annual contract.
