Plainmail

ClaudeCommunityby Plainmail

Plainmail is email hosting for people with many domains: $5 a month, flat, for up to 50 domains and 100 mailboxes. With this connector Claude can: - Add a domain and set up its MX, SPF, DKIM and DMARC records. On Cloudflare, Vercel and Porkbun the records are written for you; you approve once at your DNS host and never paste a token into chat. - Check DNS health until the domain is ready, then create mailboxes and aliases. - List, read and search mail, mark it read or move it, and send or reply from any of your addresses. Every mailbox is a normal IMAP/SMTP account, so the same mail shows up in Apple Mail, Outlook or the Gmail app. Safety: Claude never sees a mailbox password; new passwords are shown once through a reveal link. Email content is marked untrusted so Claude doesn't follow instructions inside messages. Deleting a domain requires typing its name. You choose read, send and manage permissions when you connect, and can revoke access in Plainmail settings. Plainmail is for normal mail between people. Bulk and marketing email is not allowed.
