Yes absolutely this. I've put so much effort into making sure I tick all the boxes and yet I constantly wonder if my email is getting delivered. This feels anti competitive to me. It's Google constantly telling me, give up, you know deep down you should just use Gmail.
we switched email providers from our all-EU stack to gmail... just as a last desperate attempt at not being marked as spam for actually sending low volume (crazy, right).
well, now we're stuck with gmail for a year, and no, it haven't improved anything!
I think Gmail doesn’t want you to use their service for sending email; they want you to have to advertise ‘with’ them.
