About Lumail

Lumail is an email platform where AI drafts, segments and schedules while you keep the final click. A document-style editor handles variables, buttons and an inbox-style preview, and AI tightens a paragraph on request without rewriting your voice. It supports campaigns, subscriber segmentation, workflows that handle enrollment, timing and exits, analytics and an API, and a transactional email SDK for receipts and login codes with a priority lane so a campaign never delays a one-time code.

It exposes its functions to AI agents such as Claude and Codex through MCP, with more than 100 tools, so an agent can query subscribers, tag them and enroll them in workflows, and a migration prompt lets an agent move a list, tags and sequences from tools such as Mailchimp, Brevo, MailerLite, Kit, beehiiv, ActiveCampaign, Systeme.io or Resend in under ten minutes.

Lumail is a hosted service where you pay for emails sent and never for subscribers stored. The free plan allows 3,000 emails per month with no card, and the site includes docs, a changelog and an option to book a call.
