Some email senders reporting bounced emails
For the past couple months I've been having a problem with UnitedHealthcare where they send me letters in the US Postal Mail saying "we tried to email you this information but your messages have been returned as spam." Just yesterday I had another company (Gameflip), where I was setting up an account, try to send me an email verification with a security code. That email never arrived, and now I see in their notifications that they got a bounce back.
I've seen some other threads on these forums where Xfinity employees have been able to investigate these cases and I'm wondering if that's possible to be done for my case? Specifically @XfinityCSAEmail and @XfinitySPAAbuse have replied in multiple forums so I'm hoping to get some help for my case, too.
To be clear, lots of other email to my account (the main email and one subaccount) are coming through fine, just select senders appear to be getting bounces back. Gameflip I could _maybe_ see as being considered spammy, but UnitedHealthcare?!? I think they're pretty legit. :-)
