OUR VERDICT

MailerLite is a simple, low cost email marketing tool with an AI writing assistant, AI subject lines and per subscriber send times on its $12 Comfort plan. It is the best value AI email tool for most small businesses. Some AI tools are still in beta and AI credits are limited on the cheaper plan, but the 14 day no card trial makes it easy to try.

What MailerLite is

MailerLite is an email marketing platform for sending newsletters and automated emails, with built in landing pages, pop ups and simple websites MailerLite pricing ↗. Its AI tools are grouped under the name HeyLite and appear inside the editors you already use HeyLite toolkit ↗.

It is aimed at small businesses that want a tool they can learn in an afternoon, at a lower price than larger platforms. Hands on testing is in progress. This review is based on MailerLite's pricing page and help center.

What it does well

The AI sits where you write. The AI writing assistant drafts text from a short prompt inside the campaign, landing page and pop up editors on paid plans HeyLite toolkit ↗. The subject line generator suggests several options based on your email, and it is available on every plan, including Free HeyLite toolkit ↗.

It can build an email from a description. On paid plans, an AI agent in the HTML editor creates a whole campaign from a plain English brief; MailerLite still labels it beta HeyLite toolkit ↗. AI landing pages are on paid plans, and free users can generate one HeyLite toolkit ↗.

Smart sending times each email. On paid plans, MailerLite picks a send time for each subscriber based on their past opens, clicks, sign up date and time zone HeyLite toolkit ↗.

It connects to AI assistants. An MCP server on every plan lets tools such as Claude or ChatGPT connect to your account and manage campaigns HeyLite toolkit ↗. On Free, MCP access does not include sending MailerLite pricing ↗.

The price is low for what you get. Comfort includes 50 active automations, 10 websites and landing pages and 24/7 email support from $12 a month MailerLite pricing ↗. Nonprofits get 30 percent off paid plans MailerLite pricing ↗.

Where it falls short

AI credits are not published. MailerLite says Comfort gets a limited amount of AI writing credits and Power gets the most, but gives no numbers HeyLite toolkit ↗. Heavy AI users should expect Power.

Some AI is still in testing. AI generated HTML emails are labeled beta, and HeyLite insights, which give personal recommendations on re-engaging subscribers, send times and deliverability, are in beta for a limited number of users HeyLite toolkit ↗.

The free plan is small. It allows 250 subscribers, and once you go over, campaigns and automations are locked until you upgrade or remove subscribers MailerLite pricing ↗.

The pricing page does not show how prices rise with list size, so check the calculator for your subscriber count before you budget MailerLite pricing ↗.
