Undeliverable email messages are known as bounces and bounces have further two major classifications, Hard Bounce and Soft Bounce. Your ability to correctly categorize the undeliverable messages ensures better list hygiene and sustainable sender reputation. Soft are the momentary delivery errors while permanent delivery errors are categorized as Hard bounces.
There are reasons why these delivery errors occur and large numbers of these reasons are so obvious that they have become industry standards. Like if the email address does not exist, it constitutes a permanent delivery issue and will be considered as hard bounce, 5.0.0 is the error code for email address that does not exist.
However, the way ISPs express an undeliverable message notice may vary from one another. Therefore, following industry standards in all the cases would sometimes drop level of effectiveness, and you may need to have a way out for defining some custom bounce categorization rules. This exclusive function of CampaignsPlus helps you with this.
Navigate to Custom Bounce Rule
Main Navigation -> Bounce Handling -> Custom Bounce Rules
After clicking custom bounce rules you will land on the page where you will see already defined custom bounce rules. The table may not appear empty even when you don’t have any custom rule defined yet, it would populate some default custom rules. However, these default custom rules are editable and even can be deleted if you don’t want to work with these. Let’s take a look at how we can define a custom rule for the better categorization and processing of the undeliverable messages.
Add Bounce Rules
The button appears towards the left corner of the table can would take you to the page that opens up a simple form with few fields and selections. Here are these.
One must have to fill in the information in the following fields in order to add a new custom bounce reasons.
A unique label would help you differentiate among the different custom bounce rules that you have defined or may define in the future.
A notice for an undeliverable message is delivered to the bounce mailbox carrying valuable information for the sender to know the cause as well as the possible category of bounce. Bounce codes are related to specific bounce reasons, like 5.1.6 explains that the Mailbox has moved. You need to provide that bounce code in this field to proceed.
As indicated earlier for the bounce code, non-delivery reports or undeliverable notices are translated with the help of certain parameters. Bounce codes does explain specific reason, and this field needs to be filled with that reason, e.g. Mailbox Full.
System loads default selections, you need to however select your preference for the function to work properly.
Bounces are generally classified into two types, hard permanent and soft momentary errors. You are being offered with the following options to select an appropriate.
- Soft- Selected by default, if kept on selected then the bounce with the above mentioned code and reason will be stamped as processed as soft bounce.
- Hard- If selected then undeliverable message notice with the above mentioned bounce code and reason will be processed as hard bounce within your account. And no further emails will be sent to that contact.
- Don’t Process- Select if you want to ignore undeliverable message notices with the particular bounce code and reason, and don’t want to process them soft or hard bounce either.
If you want to apply this rule straightaway, then select “Active”, select “Inactive” otherwise.
How it Works?
When the bounce processing function connects to the bounce mailbox and starts reading the notices for undeliverable messages, it first attempts to match the bounce code and reason with the available bounce codes. That means, if non-delivery report matches with a custom bounce rule, bounce will be processed according to the custom defined rule. If bounce processing function of CampaignsPlus doesn’t find an appropriate option for the bounce within the custom defined rules, it automatically moves to the next level, and the next level is Industry Standard. System in its default structure has defined bounce categorizes according to the set industry standards, i.e. message length exceeds administrative limit (5.2.3) will be processed as Hard bounce as per Industry Standards. However if you don't want to process it as Hard Bounce, you need to configure a custom bounce rule for this reason.
