The messages don't appear in any folder, and I have reverb.com on my contacts
Reverb.com appears to have all the DMARC, SPF and DKIM config required by Microsoft. So if the mail to you is getting bounced, it's probably because Reverb's "reputation" with Microsoft has dropped below the threshold to allow delivery.
Did you ever get anything from Reverb? When did it stop?
Reverb acknowledges that there are problems delivering to Microsoft Domains. Do a search for:
Managing your Reverb account Why am I not receiving emails from Reverb?
We see some email domains being more problematic than others, such as Hotmail. In these situations, we recommend changing your Reverb email to a more reliable email domain, such as Gmail.
Ask Reverb to do a test and trace.
Contact Reverb Support via their Live Chat. Ask them to send a test email to your account and look for any Non-Delivery Reports on their end.
