Wonderful timing! I already have one domain approved and can confirm it's an awesome tool thanks :)

ps. I suspect that this will provide people a very simple way to migrate to using free Gmail as their email solution. (though in my case, I've taken the free Gsuite product closure as an incentive to fully de-Google).

Agreed. Time for me to move to something that I completely control myself and can keep it running as long as I want.

This is a very interesting option for handling incoming email from a personal domain or two (especially since it's from an established company, rather than a random individuals's email forwarding service :)

Does Cloudflare have any options for handling outgoing email? If not, I assume you still have to set up your actual email host in a way that can send through all the vanity domains, with appropriate DKIM records, etc.

If you were to use free Gmail, this allows you to send via other email addresses (so you could forward [email protected] to your Gmail and send emails as coming from that email address). See https://support.google.com/mail/answer/22370?hl=en

Can that completely hide that real sender ([email protected]) without setting up a SMTP server? Seeing "[email protected] on behalf of [email protected]" or ending up in spam would be a deal breaker.

No I don't think so

Actually, I was wrong: it looks like there's no longer an option to do that from Gmail :(

Does Cloudflare Email Routing support Sender Rewriting Scheme (SRS) https://en.wikipedia.org/wiki/Sender_Rewriting_Scheme ?
