  2. any errors when sending other types of emails, such as the Welcome Email?
    yes, same issue.

  3. what happens if you click on Try under the Verification Email (using link) and enter a valid email?
    it shows Email was successfully sent. But according to log:

"error": "Message failed: 554 5.0.0 Error: transaction failed, blame it on the weather:  ##SES-response-json:{\"Response\":{\"RequestId\":\"488dbec0-03da-43a8-8aed-0afb1c66aa12\",\"QcloudError\":{\"Error\":{\"Code\":\"FailedOperation\",\"Message\":\"msg.From is null\"}}}}"

And I found that even if I close Use my own email provider, I still can’t send emails
