Plainmail

Real email on every domain you own, for $5 a month flat

Get picks like this daily. Today's launch numbers, the top launches, AI and tech news, and a daily opportunity pick, straight to your inbox.

Real mailboxes on all your domains for $5 a month, flat: up to 50 domains, 100 mailboxes and 25 GB. Ask Claude for hello@yourdomain through the MCP server, or use the CLI or API. Plainmail writes the MX, SPF, DKIM and DMARC records at Cloudflare, Vercel or Porkbun, checks them and creates the mailbox. It's a normal IMAP/SMTP account, so it sits in Apple Mail, the Gmail app, Outlook or Thunderbird. Built for mail between people, not bulk mail.

Could you build this?

Partial DNS record automation through the Cloudflare, Vercel, and Porkbun APIs is vibe-codeable, but running reliable mail hosting with good deliverability is hard.

What it would actually take: The stack would be a mail server such as Stalwart or Postfix/Dovecot, DNS automation via provider APIs, and a billing and admin panel. The hard part is deliverability: IP reputation, warm-up, spam filtering, abuse handling, and blocklist management. That requires operations experience with email infrastructure, not just code generation.
