Types of email errors
Payt distinguishes between two types of email delivery failures:
Soft bounce: The email cannot be delivered temporarily, for example, due to a full inbox or a temporary issue with the mail server.
Hard bounce: The email cannot be delivered permanently, for example, because the email address does not exist or is misspelled. In this case, the email address will be blocked.
Handling undeliverable emails
In the 'Email' tab under your administration settings, you can define how Payt should handle undeliverable emails. There are three options:
Block the invoice
The invoice is blocked, and no further actions are taken.
Send a letter
The failed invoice step is resent by post.
Subsequent actions will be retried via email.
Block the invoice and send a letter
The failed invoice step is resent by post.
The invoice is then blocked, preventing further actions.
For both invoices where the invoice is sent by post, you can specify whether this should apply only if the bounced email address was in the 'To' field or also if it was in CC or BCC.
What happens when a large number of emails suddenly can't be delivered?
Sometimes many emails can't be delivered in a short period of time, for example, because something has changed in your email settings. To prevent a large number of backup letters from being sent, Payt will automatically pause backup letter sending if you have this configured.
This happens when at least 100 emails have been sent in one week, and at least half of them could not be delivered.
Have you received a notification that backup letters have been paused because many emails could not be delivered? Please contact the service desk. They'll help you check your email settings and resume letter sending afterwards.
