Assuming you are using SmartZone webmail to access your email, you can check the SPAM folder to see if there's anything in there from Sears. If it's being blocked by Comcast, I believe it will show up in the spam folder, but I'm not an email expert. I'm assuming "blocked" emails would appear in the spam folder. The spam folder is near the top-left side of the screen.
I have signed up multiple times for email from sears.com and haven't received any within two weeks. Is there anyway to find out if Comcast is blocking them from my email account?
Have you been able to receive emails from them in the past? If yes... Do you have one of those old emails? If you do, copy/paste the header from an old message and post it for review. Do remove the beginning of all email addresses from the header, but leave the domain. (email@example.com) If you need help with viewing posting a header, let us know.
