I got newsletter set up. 1 fake subscriber with bad email. I test welcome msg. I see it goes to error account.
I got bounce set up. Connects to error account that currently has 1 email error.
Run test and run now says 0 errors.
The 1 email error is deleted.
The newsletter still says subscriber confirmed.
Bounce plugin is not perfect an probably is not able to extract the erroneous email from the error message. You can try to send em the source of the error message so I can verify if it’s possible to extract the wrong email address.
