SendAs Bridge – Send as your domain in Gmail nga Cedar Labs

Gmail is removing "Send mail as" for addresses it doesn't host: Google's help page says it ends in January 2027. If mail to you@yourdomain.com is forwarded into Gmail, it keeps arriving, but replying as yourself stops working.

SendAs Bridge brings the sending half back, inside Gmail.

HOW IT WORKS
• Every Gmail compose window gets a From row. Pick your own address.
• Write as usual and click Send (or Cmd/Ctrl+Enter).
• SendAs Bridge sends the message through your own email provider's API — Resend, Amazon SES, Postmark and other providers — and removes the Gmail draft.
• A copy is Bcc'd to your Gmail, so it appears in the conversation you replied to.

A REAL EMAIL, NOT A WORKAROUND
• Replies stay in the same conversation: In-Reply-To and References headers, the "Re:" subject and the quoted history, like Gmail.
• Attachments, pasted screenshots and pictures from the quoted message are sent properly.
• Replying to mail sent to your domain picks that address automatically.
• Undo send, a signature per address, and clear errors that say how to fix them. Your draft is never lost.

SET UP IN ABOUT 10 MINUTES
• Step-by-step setup for each provider. Most providers have a free plan that covers personal mail.
• A domain check reads your SPF, DKIM, DMARC and MX records and says in plain words what to add.
• Send yourself a test email, and get a ready-made Gmail filter for your sent copies.

PRIVATE BY DESIGN
• No SendAs Bridge servers: Firefox talks directly to your email provider.
• Never asks for your Gmail password or Google tokens.
• Your provider API key stays in this browser, optionally encrypted with a passphrase (AES-256).
• Permissions: Gmail, plus only the provider you connect (asked when you connect it).
• No analytics, no tracking, no remote code.

FREE AND PRO
• Free: one address, with every sending feature.
• Pro ($19 once, for up to 5 browsers): unlimited addresses and domains, more than one provider, and catch-all addresses (*@yourdomain.com).

GOOD TO KNOW
• You need a domain you own and an account with an email provider.
• Works in Gmail on the web in Firefox for desktop. Not in Gmail's mobile apps or Firefox for Android, and not in private windows.
