" I never signed up to receive any emails from this person." No you only signed up to receive email from AHS. He has violated that relationship. This is why it's better for any organization, especially with this group size, to use an email platform - it protects the group and it has ways to report inappropriate use. There are many free options (should anyone be considering this large type of communication).

1. Ask to be removed from the email list and hope that works.

2. Ask to be removed and report the email as spam. Because your original email was acquired for transactional purposes, not commercial, and it's now being misused, you can report it as violation of the CAN-SPAM Act. But the only place you can really report it to is your email provider (via your email system). If the originating email address receives too many spam reports, it could be shut down.

That is exceedingly irritating.
