MailerLite is an email marketing platform, a hosted service that stores a business's list of subscribers and sends newsletters and automated emails to them. The company MailerLite started the product in 2010 and works as a fully remote team.
A business collects subscribers with signup forms, landing pages, pop-ups or an iPad app at events, then designs emails in a drag-and-drop, custom HTML or simple editor. Automations send timed and targeted emails when a subscriber does something, for example joins the list. The platform also builds websites and blogs, sells digital products and paid newsletter subscriptions, and books appointments. Other features are an AI writing assistant, A/B testing (two versions of an email sent to compare results), an API for developers, and an MCP server, a connector in the Model Context Protocol standard that lets AI assistants such as Claude and ChatGPT manage campaigns.
MailerLite is used in the browser. A Free plan covers up to 250 subscribers and 2,500 emails a month; the paid Comfort, Power and Enterprise plans are monthly subscriptions.
