You're spot on about Google; they've moved forward from this approach and lean more heavily on domain-based information now. But they're a rare exception, and they have very little to go on when the domain is just "sendgrid.com" (i.e. the customer hasn't set up whitelabel yet). So we want to make sure we're always giving customers new or cooled IPs!
- linkregister 9y agoI'm surprised you willingly burn your own domain's reputation. Other email-as-a-service companies require a validated domain with SPF and DKIM in the DNS TXT records or use a burnable subdomain, e.g. freeaccount12345.sendgrid.com; or even better, 12345.sendgridfreeaccount.com.
- etjossem 9y agoYep, we use burnable subdomains if you haven't whitelabeled.
