When my users register for an event that I setup in Wix events, they receive a confirmation email message. Some of my users are complaining that they do not receive the confirmation email. I’ve narrowed it down to Comcast users. I have a Comcast account so testing is easy. The message isn’t in any folder (Junk/SPAM/Inbox, etc.) There is not bounceback message. I’ve done a message trace and the messages come from mailer.wix.com then to sendgrid.net
(Message trace done on received confirmation from my gmail email address). Then delivered. This all worked a month ago. Nothing has changed, but I am using the new Events module. I put in a support ticket with Wix and they said I need to contact Comcast and have the IP/site unblocked. I did contact Comcast and they say the site isn’t block. Any thoughts on how I should proceed?
Thanks.
