Bounce Handling

Bounce handling refers to managing email messages that couldn't be delivered to the recipient’s inbox. When an email fails to deliver, the email server sends back a "bounce" message indicating the reason—such as a full mailbox or invalid address. Bounce handling involves processing these messages to identify and categorize the failed deliveries, so senders can correct issues, remove invalid addresses from their lists, and maintain a good sender reputation. Effective bounce handling helps improve email deliverability, ensuring future messages reach intended recipients successfully.
