Filtering rules

Filtering rules let you define the messages to exclude based on criteria defined in a query. These rules are linked to a targeting dimension.

Filtering rules can be linked to other types of rules (control, pressure, etc.) in typologies, or grouped in a dedicated Filtering typology. For more on this, refer to Creating and using a filtering typology.

Create a filtering rule

For example, you can filter your newsletter subscribers to prevent communications from being sent to recipients who are underage.

To define this filter, apply the following steps:

1. Create a Filtering typology rule applicable to all communication channels.

   

2. Change the default targeting dimension and select the subscriptions (nms:subscription).

   

3. Create the filter using the Edit the query from the targeting dimension… link.

   

4. Link this rule to a campaign typology and save it.

   

When this rule is used in a delivery, underage subscribers are excluded automatically. A specific message indicates rule application:

Condition a filtering rule

You can restrict the application field of the filtering rule based on the linked delivery or delivery outline.

To do this, go to the General tab of the typology rule, select the type of restriction to apply and create the filter, as shown below:

In this case, even if the rule is linked to all deliveries, it will only be applied to those which match the criteria of the defined filter.

Create and use a filtering typology

You can create Filtering typologies: they only contain filtering rules.

These specific typologies can be linked to a delivery when the target is selected: in the delivery wizard, click the To link, then click the Exclusions tab.

Then select the filtering typology to be applied to the delivery. To do this, click the Add button and select the typologies to apply.

You can also link filtering rules directly via this tab, without them being grouped in a typology. To do this, use the lower section of the window.

Default deliverability exclusion rules

Two filtering rules are available by default: Exclude addresses ( addressExclusions ) and Exclude domains ( domainExclusions ). During the email analysis, these rules compare the recipient email addresses with the forbidden addresses or domain names contained in an encrypted global suppression list managed in the deliverability instance. If there is a match, the message is not sent to that recipient.

This is to avoid being added to the denylist due to malicious activity, especially the use of a Spamtrap. For example, if a Spamtrap is used to subscribe via one of your web forms, a confirmation email is automatically sent to that Spamtrap, and this results in your address being automatically added to the denylist.
