Gmail is one of the shoddiest of the ultra-cheap email providers. If you use Gmail, a significant number of messages will disappear. They don't go to junk, they just disappear. Gmail will reject messages for obscure technical reasons. They recently decided that they would no longer accept messages signed with 1024 bit RSA DKIM. So, with no public announcement they just turned on the restriction. I found out about this from a random Mastodon poster who wasn't really sure what was going on. The error message returned to the sender gave no indication at all.

Gmail is the email provider for people that like to claim they never got the email. Google has somehow made the most reliable messaging medium, unreliable.

It is obvious that Google simply doesn't care about email. So it makes perfect sense for them to use Gmail to promote something that they do care about.
