How to troubleshoot MemberStack password reset emails returning success but not arriving?

Hi Memberstack team, we're experiencing an issue with password reset emails and were hoping you could help investigate.
We're using Memberstack's transactional email sender with the verified sender.
Previously, password reset emails were working, but recently no password reset emails are being delivered to any members.
We've verified:

memberstack.sendMemberResetPasswordEmail() returns HTTP 200 with the standard success message.
It affects all email addresses.
The sender is verified.
Emails aren't arriving in Inbox, Spam, Junk, or Promotions.
No application code changes were made before this started.

We also noticed the sender is marked as being on the Legacy provider. Could that be related? could you check whether password reset emails are actually being generated and sent from our project on your side?

Muhammad Shahshan sharing solution here to see if it helps.

Ken Jones yes! I just found your app and see that you are on our old email service.

I highly recommend, deleting your custom email domain, and then adding it back. It will give you new DNS records to add.
