I work for a public library, and we are also experiencing the same issue. Our domain is wblib.org, we use GSuite for Nonprofits for email. Audit logs show successfull deliveries: Nov 24, 2020, 09:00 0.47 seconds
Delivered to an SMTP server with IP address: 2001:558:fe16:1b::15 (TLS enabled) But the patron does not receive the message in their inbox, spam, etc. We have had multiple patrons complaining about this issue and it's impacting our (opt-in) notices, as well as things like registrations for virtual programs. We have only received complaints from patrons with comcast.net email addresses. @ComcastCSAEmail is this something that you can look into? Thank you.
