Since last fall, we've been banging our heads against email delivery issues to our newsletter subscribers, seemingly automatically quashed by an AI-fueled process, despite our newsletters only being sent to confirmed subscribers; implemented with all best practices for email sending infrastructure, opt-out and sender disclosure; and never having problems like this before.
I think we've now tracked down the culprit and have mitigation measures ready, tied with our upstream support. We're going to give this another try today and then work through any issues we encounter, now that we have the proper support engaged.
I am anxious to get this key element of our publication going again and thank all our subscribers for your patience while we've been getting this worked out. Cheers!
