Hi Andy0000,
Thanks for reaching out and welcome to the Community Forum.
Sorry to hear about the email bounce back. I understand how important it is that emails get sent, especially pay slips. There are a lot of possible reasons why an email gets undelivered, but regardless of the reason after the email failed to be delivered, you should receive an email within 10 hours of the failed email regarding why the pay slip has failed to be sent. I would suggest checking the email address associated with the account for any information regarding the undelivered email.
Let us know if you require any further assistance with this. We're happy to help.
Cheers,
Genreve
