FAQ

Is Gmail really removing Send mail as?

Yes, for addresses Google doesn't host. Google's help page says: "You will no longer be able to send mail from third-party email accounts in Gmail on the web or in the Gmail mobile apps." It shows a notice in Q3 2026, may restrict new setups in Q3–Q4 2026, and fully removes Send as for third-party accounts in January 2027 (Gmail Help 17101213). Sending as another Gmail address or a Google Workspace alias isn't affected.

Which addresses work with SendAs Relay?

Any address whose provider lets mail apps sign in to SMTP on port 465, 587 or 2525: Yahoo, AOL, AT&T, iCloud, GMX, Web.de, Fastmail, Zoho, Purelymail, Migadu, Forward Email, ImprovMX, Brevo, SMTP2GO, Mailjet, Resend, Mailgun, Comcast/Xfinity, and most own-domain mail hosts. Setup has presets for these.

Why doesn't it work with Outlook.com or Hotmail?

Since 16 September 2024 Microsoft has accepted only Microsoft sign-in (OAuth) for Outlook.com, Hotmail and Live mailboxes, not passwords or app passwords. Support through Microsoft sign-in is planned. Until then, see options for Outlook and Hotmail.

And Proton Mail?

Proton offers SMTP only through Proton Mail Bridge, an app running on your own computer, which an online relay can't reach.

Do you see my emails or passwords?

They pass through the relay for the few seconds it takes to hand the message to your provider, over an encrypted connection, and are not stored. The relay has no database and its logs are switched off. You don't have to take our word for it: the relay is open source, and you can run your own so nothing goes through our servers. Details on the security page.

Why do I need an app password?

Yahoo, AOL, iCloud, Fastmail, Zoho and many others don't accept your normal password from mail apps once two-step sign-in is on. An app password is a separate password that only allows mail access, and you can revoke it at any time. The setup screen links to your provider's instructions and tests the password before saving.

Will my sent messages show up in Gmail's Sent folder?

If you choose "Save to Gmail Sent", yes: after sending, the relay saves a copy into Gmail's Sent Mail using a Gmail app password. You can choose a Bcc to your Gmail address or no copy instead. How it works.

Will replies stay in the same conversation?

Yes. For replies, the extension reads the original message's ID from your Gmail and adds the In-Reply-To and References headers, so the reply threads for you and for the recipient. If it can't read them, it still sends and tells you the reply may start a new conversation.

Do recipients see "via gmail.com" or "on behalf of"?

No. Your provider's server sends the message, so recipients see your address, exactly as if you'd used your provider's own webmail.

Can I keep my current Send mail as setup until January?

Yes. SendAs Relay doesn't touch your Gmail settings. Your Gmail address is the first option in the From menu and sends through Gmail as before; your other addresses go through SendAs Relay. You can switch per message.

Does it work in Chrome?

Not from the Chrome Web Store yet. It works in Microsoft Edge (version 137 or later), which runs Chrome extensions, and in Firefox 140 or later.

Does it work in the Gmail app on my phone?

No. It's a desktop browser extension for Gmail on the web. On a phone, add your other account as a separate account in the Gmail app, or use your provider's app.

What about attachments and pictures?

Attachments up to 14 MB in total and pasted pictures are included. Files you added with Gmail's paperclip are included when the extension can read them; if it can't, it doesn't send and asks you to attach them with its own Attach button instead. Google Drive links work like any link.

Can I schedule a message or undo send?

Not for your other addresses: the message goes out as soon as you click Send. Your Gmail address keeps Gmail's scheduled send and undo.

What if Gmail changes its layout?

If the extension can't recognise a compose window, it refuses to send and says so, rather than sending an incomplete message. You can send with Gmail and update the extension when a fix is out.

What does it cost?

Free for one address, with every feature. Pro adds unlimited addresses for $19 a year (planned; not on sale yet). Running your own relay is free. See pricing.

What happens if SendAs Relay shuts down?

Your settings are on your computer, and the relay is open source. Deploy it to your own free Cloudflare account, paste its URL in the settings, and keep sending.

Is SendAs Relay made by Google?

No. It's an independent extension by Adam Hale, not affiliated with or endorsed by Google.
