One of my paid apps has recently hit the ridiculously low email quota of 100. So looking at the official docs - I followed the recommendation of moving to Sendgrid.
Guess what ? Each and every email sent through Sendgrid ends up in the spam folder on ... Gmail. The explanation to this, as appears in Gmail is that many emails sent through Sendgrid were previously identified as spam. So GCP recommends Sendgrid, but Gmail blocks it ???
