Some of my messages are getting deferred when using sendgrid. I have a list of about 3000 emails but they all have the same domain name. What measures should I take when I send to lists that have the same domain. I have other lists too the have the same domain. Does MW treat deferred emails as bounced? In MW it says soft bounce but when I go to my sendgrid account it says deferred.
