I don’t totally understand what this topic is about, but DO has big amount X e-commerces as a customer and every single one uses some service for theirs emails. I’m using Amazon SES.
And reason for that is it has been impossible to host your own mailserver in the meaning you can send directly to receivers. If they have closed the last hole that allowed it I’m fine with that.
But again, I don’t even know if I’m talking about same thing.
