Bounce Addresses

A bounce address is the return-path address in your email header that is responsible to receive delivery reports of the failed messages. Without a bounce address, your email isn't fully qualified and technically it's the main sender of the email that authenticates SPF (Sender Policy Framework).

While rendering the email message for delivery, Mumara embeds the bounce address into email headers as per your selection during the scheduling process.

How it works

Bounce cron runs every 2 hours by default however you can modify the processing time in Cron Settings. Once the bounce cron executes, it tries to log in to the bounce mailbox with active status using the saved authentication details. Upon a successful connection, it will look for new/unread emails and start reading them to understand the content. A delivery report email contains important information e.g. message-id of the email, bounce code/reason, and other informative details for tracking purposes. Mumara matches the delivery report of the failed messages within campaign logs and finds which campaign it belongs to and which contact it exactly is, and classifies the contact as soft/hard bounced after finding the matched bounce reason. You are also able to see the bounced emails under the "Bounced" tab in broadcast statistics. Moreover, you can also modify default bounce rules.
