whats the domain of the email that is being blocked?
if the issue is with the same email you used to sign up for these forums - they arent sending you emails at all(or at least in the last 14 days). The domain itself overall is not being blocked or filtered by comcast.net servers.
Yes, these emails (which are automated class confirmation emails) are being sent to < removed>. The entire email address they are coming from is <redacted>@mindbodyonline.com . The last email I received in my inbox from this email address was on 6/28/20. However, it has been confirmed by "<redacted> @mindbodyonline.com" that 3 additional emails were sent to my email address between 6/28/20 and today. One specifically should have come through on 7/19/20 @ 10:00pm.
@itstracey I had to edit your post to remove violations to the Xfinity Forums Guidelines: https://forums.xfinity.com/t5/Guidelines/Xfinity-Forum-Guidelines/td-p/3115028
please dont post any personal identifiable information publicly in the forums.
From what i did see, it confirms that they never actually sent the email to you. The email never reached the comcast.net server indicating that they are sending you an email. The sender will want to audit their email logs to see what may have happened to the email when they attempted to send the email.
