Defining an email address from your custom domain at Cloudflare

A few weeks ago (so not really a Today I learned) I wanted to see if I could get an email address using my domain. Turns out I can - and someone already built the guide for that:

There were additional DNS tweaks I needed to do in order to get it working:

I changed my _dmark TXT entry to:

"v=DMARC1; p=none; asp=r; adkim=r;"

and hanged a root TXT entry to

"v=spf1 include:_spf.mx.cloudflare.net include:_spf.google.com ~all"

to include the Google spf address.

Then - I was able to use my custom email address from the gmail app / website seamlessly.

The end result is something like this:

Gmail allows to pick from which email address to send the emails from. Similarly, emails received to that configured address will show up in the inbox.
