Your mailing list, run from Claude.

A form on your site, a confirmation email, one-click unsubscribe. Then you ask Claude: how many signups this week, write this month’s letter, send it.

Clean signups

Double opt-in, proof of consent kept for every address, an unsubscribe link and the one-click header in every email.

From Claude

An MCP connector: subscribers, stats, CSV export, draft, test send, then the real send when you say go.

Your data

Addresses stay with you, stored in the European Union. Export everything as CSV whenever you want.
