You can do this without masked email too. I have a wildcard alias setup so *@mydomain.tld are accepted, and I have a wildcard sending identity *@mydomain.tld

If you have a sending identity that matches with the address the email was received, on the app and webui it will reply from that address.

Disclaimer: I work at Fastmail, but not on the webui or app.

Fastmail does SUCH a great job managing multiple addresses and domains. My favorite feature is the auto-BCC so that when I'm sending from a joint e-mail address I share with my wife, she always gets a copy.

Thanks, I didn't know this was an option. Turning on now. :)

I am a Fastmail customer for 2-3 years. That was the reason, why I switched to you guys!

I've been trying to decide if I should switch from GApps to Fastmail. This is the killer feature I wanted along with unlimited domains, looks like I'll be transferring over soon.

Uh. Neat, I’ve been adding aliases individually as I needed them.

I did that too when I used Fastmail, was a right pain, wish I'd known!

It never occurred to me to try a wildcard. I was getting sick of adding sending identities in fastmail. Thanks for the tip!
