Plainmail
Real email on every domain you own, $5 a month flat
Plainmail gives you real mailboxes on every domain you own for $5 a month, flat. Sign up with GitHub, add a domain, and it writes the MX, SPF, DKIM and DMARC records at Cloudflare, Vercel or Porkbun for you. Mail arrives as a normal IMAP/SMTP account in Apple Mail, Gmail, Outlook or Thunderbird — no new app to learn.
