This is more widespread than just Sendgrid. We noticed an increase in various "postal service" phishing / scam attempts in the past couple of months, and they try to impersonate not only USPS, buth DHL (in German and English languages), Royal Mail, La Poste (French) and some others.
Most accounts that attempt this sort of scam are registered via various VPN services' ranges, however we noticed a few that were registered directly from IP addresses in Morocco. They are also trying email / password combinations from public leaks to try and take over legitimate accounts. If anyone is interested in sharing knowledge about this gang and working on prevention together, reach me off list, as these list messages are public.
