Recently mail sent from my sendgrid account to Cox recipients is being blocked.  See the error message below.  My Sender reputation is 99%, I'm not sending spam, these are to recipients who have opted in .  All my emails contain unscubribe links.

I'm using sendgrid to send mail for membership@sandbridgecivicleague.org
