Run your newsletter on autopilot with AI agents
Draft, segment, and schedule campaigns automatically to your whole list — then review and edit everything in a visual editor. Pay for emails sent, never for subscribers stored.

Tuesday · 09:00
A different kind of email tool. Built for people who write, ship and sell on their own — Lumail keeps the whole list in one system, and lets an agent drive it when you would rather not click.
One pipeline
Campaigns, sequences and transactional email leave through the same verified domain, with the same deliverability.
Every action is a tool
89 organization-scoped tools over MCP. Whatever the dashboard can do, your agent can do — with your permissions.
Runs without you
Welcome flows, drips, conditional branches. Build the sequence once and it keeps sending while you write the next one.
Write the email, not the layout
That is not a screenshot — it is the actual editor, running right here. Select a word for the formatting menu, type “/” to drop in a button. In the app, ⌘J tightens the paragraph you selected and never rewrites your voice behind your back.
- Variables and conditional blocks
- Plain-text and HTML from the same draft
- Preview across clients before you send

Your agent has the same keys you do
Connect Lumail to ChatGPT, Claude, Cursor or your own code, and 89 organization-scoped tools show up. Query subscribers, draft a campaign, launch a sequence, read the numbers — in the conversation, not in a dashboard.

- Scoped to one organization, revocable at any time
- Every agent action lands in the activity log

89 tools. Whatever the dashboard does, your agent does.

“Lumail made me like email — it turned email from a side thing into the main marketing channel for my Linkhub business.”
“I'm not a marketer, but email is powerful. Thanks to the Codex integration, Codex actually implements all the marketing for me.”
“I was using MailerLite and sending emails was a constant stress. Now my agent reviews it, fixes it, and sends it for me. I've sent over 3 million emails with Lumail.”
Creators, indie founders and small teams send with Lumail every day.

Do you charge per subscriber?
No. There is no subscriber limit on any plan, and no line on your invoice for list size. Import 50,000 contacts on day one if you want — the price only moves when you send.
So what will it actually cost me?
The first 3,000 emails each month are free, no card required. Premium is $20/month with 20,000 emails included, then $0.0006 per extra email. A 20,000-person list emailed four times a month is 80,000 emails — $20 plus $36 of overage, so $56. Run your own numbers in the calculator on this page.
How is this different from Mailchimp, Kit, or Beehiiv?
Some competitors now expose MCP too, so compare the real workflow instead of the AI label. Lumail's full catalog has 89 organization-scoped tools across campaigns, workflows, subscribers, analytics, and transactional email, with a visual app, CLI, SDK, and API beside them. The billing model is the other difference: Lumail prices emails delivered and stores unlimited subscribers, so a dormant record does not raise your bill.
Can Lumail send my app's transactional emails too?
Yes, and that's the point. Point your app at our SMTP relay (smtp.lumail.io:587, STARTTLS) or the API and your password resets, receipts, and OTPs ship from the same place as your newsletter. They travel in a separate instant lane, so a 50,000-recipient campaign can never make a login code wait.
Do I need to be a developer to use Lumail?
No. Everything runs from the dashboard: a visual workflow builder, a filter builder for segments, and an AI-assisted editor. The API and SDK are there when you want them, not a prerequisite.
Can my AI agent run my newsletter?
If you already work in Claude Code, Cursor, or another MCP client, add your API token and 89 organization-aware tools show up. Ask for a campaign, a segment, or last month's numbers and the agent does it. Entirely optional — the dashboard does the same job.
Don't take our word for it.
Pick the question you actually have. We hand it to the assistant you already trust — unedited, with our own site in scope.
“I run a newsletter and I'm considering Lumail (lumail.io) for it. Read their site and tell me honestly who Lumail is a good fit for, who it is a bad fit for, and what I should check before switching.”
