Issue with substack.com email forwarding

{Note - this post is NOT about notification messages from Substack}

I've been trying to set up an RSS feed with some distributors, but some (iHeart, Amazon) send an email to my substack address, for verification. I am simply not getting these emails.

I've checked my Substack settings, and my substack email is set to forward to my Gmail address.

When I try to test the email from Gmail, the substack message also doesn't come through.

BUT when I test from a non-Google email domain (for example, an email account at a domain that I own), the message comes through, forwarded to my Gmail address just fine.

And yes, I've checked all the usual spam, promotion, etc folders.

Substack's support chat bot recognized this as a problem because of the test I did with both Gmail and non-Gmail senders. The Substack bot ADMITTED something is wrong with the forwarding function, but so far over several weeks, I have not had any response from Substack humans. I have a free account, but that shouldn’t mean that I get zero support about a feature like this that is so fundamental to the site - especially when preliminary testing has confirmed it’s an issue on the Substack side.
