Steve’s Review of Postmastery Vs Greenarrow

The bounce processor is an important component of GreenArrow’s email software that is responsible for processing bounce messages received at bounce mailboxes. Bounce messages are parsed to determine the reason for the bounce, the recipient address, ListID, and SendID of the message. Each processed bounce triggers a bounce_all event.

Bounces are attributed to the email address that GreenArrow sent the email to. This means that if an email is sent to AddressA, which forwards to AddressB, and AddressB generates a bounce message, GreenArrow will interpret the bounce as being for AddressA.

The bounce processor tracks the number of bounces to an email address and the amount of time the email address has been bouncing. It combines this information with its configuration to determine if the email address is no longer valid. If it is determined that an email address is no longer valid, the bounce processor issues a bounce_bad_address event so that the email address can be deactivated in the database.

The bounce processor is designed to avoid deactivating valid addresses while ensuring that all invalid addresses are identified. Proper bounce processing is crucial for deliverability, as sending to a high percentage of invalid addresses can result in being blocked.

There are different types of bounces, including hard, soft, and other bounces. Hard bounces indicate that an email address is not valid, while soft bounces are error conditions that may indicate a temporary failure in delivery. Other bounces include error conditions that do not explicitly mean that the email address is bad, such as spam blocking.

Bounce messages are categorized into different bounce codes, each with a default type (hard, soft, or other). Bounce codes provide additional information about the reason for the bounce, such as bad email address, temporary failure, mail block, spam detected, etc.

GreenArrow’s bounce processor also implements a repeat bounce counting system to determine if an email address should be marked as bad. The system tracks the number of bounces, the time between bounces, and allows for a configurable number of missing bounces before marking the email address as bad. This system helps ensure that only consistently bouncing addresses are marked as bad.

You can view statistical information about bounces by looking at a send’s statistics in GreenArrow Engine’s web interface. The bounce processor processes both synchronous and asynchronous bounce messages, which can be monitored through the bounce processor’s log file.

Overall, the bounce processor plays a critical role in effectively managing bounce messages and maintaining good deliverability for email campaigns. By accurately identifying invalid email addresses and deactivating them, senders can improve their email delivery rates and maintain a positive sender reputation.
