Email Bounce Definitions

Rosterfy utilises Amazon Simple Email Service (Amazon SES) for our email communications and as such, are informed of email Statuses which will typically include 'Hard' and 'Soft' Bounces - outside of traditional email statuses.

A 'Hard' Bounce, is defined by a 'Permanent' status, and should be actioned by removing from future communications should your email history, or report from Rosterfy indicate that these emails have not been received due to one of these permanent reasons.

A 'Soft' Bounce, is defined by a 'Transient' status and you can typically retry and send the initial, or new communications, after a short while.

The bounce email, which was sent to the address in the Return-Path header of the email that resulted in the bounce, might contain additional information about the issue that caused the email to bounce.
Permanent	General	The recipient's email provider sent a hard bounce message, but didn't specify the reason for the hard bounce. Important When you receive this type of bounce notification, you should immediately remove the recipient's email address from your mailing list.

Permanent	Suppressed	The recipient's email address is on the Amazon SES suppression list because it has a recent history of producing hard bounces.
Permanent	OnAccountSuppressionList	Amazon SES has suppressed sending to this address because it is on the account-level suppression list. This does not count toward your bounce rate metric.

You might be able to send a message to the same recipient in the future if the issue that caused the message to bounce is resolved.
