Managing tracking consent with other applications

The __clt field is not automatically applied to every delivery method available in Contactlab. Its behavior depends on the system used.

SmartRelay​

SmartRelay does not use the __clt field. The customer is therefore responsible for managing tracking preferences.
To enable or disable open and click tracking, use the specific SmartRelay headers in each email.

SOAP API and XMLDelivery​

Automatic tracking management through __clt is supported for bulk deliveries and deliveries managed through XMLDelivery, provided that the field is present in the user database.

In these cases, Contactlab uses the value associated with each recipient:

  • with __clt = 0, the communication is delivered without individual open and click tracking;
  • with __clt = 1, the communication is delivered with individual open and click tracking enabled.

The __clt field is not applied to SendImmediate deliveries, which are used for one-to-one deliveries through the SOAP API.
For SendImmediate deliveries, or when __clt is not available for deliveries managed through the API or XMLDelivery, tracking can be disabled for the entire delivery by using an email group configured without tracking.

To change this setting:

  1. open the configuration of the email group used for the delivery;
  2. locate the default tracking preferences;
  3. disable open and click tracking;
  4. save the configuration.

How to change the default tracking values in the email group

The email group configuration applies to the entire delivery and does not distinguish between recipients based on their individual __clt value.
