WorkMail is a bring-your-own-key mailbox built on Resend and Supabase. Paste an API key and you're in — no sign-up, no password, nothing to remember but a link. Compose rich HTML mail with bold, italic, headings, and color; send from any address on your verified domain; and receive replies straight to your inbox once you wire up one webhook. It's mobile-friendly, fast, and built for people who'd rather own their infrastructure than hand it to another SaaS.
