I fail to see the point: that we do the work that sendgrid should be doing, but
on a duplicative scale?
Why don’t they police themselves?
We’re effectively calling out spam that’s escaped after the fact. What’s the
point of that?
They should be scanning email as it leaves their infrastructure and using rules
and Bayesian filters to know if something is amiss and they need to have human
intervention.
Nothing is stopping them from doing the right thing.
Why should we enable their bad behavior?
