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 for an individual email, use the headers described in the SmartRelay special headers documentation.
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 open and click tracking; - with
__clt = 1, the communication is delivered with open and click tracking enabled.
SendImmediate
The __clt field is not applied to SendImmediate deliveries, which are used:
- for one-to-one deliveries through the SOAP API;
- for emails sent through Automations > Marketing Automation.
For SendImmediate deliveries sent through the SOAP API, or when __clt is not present in deliveries managed through the API or XMLDelivery, tracking can be disabled by using an email group configured without tracking.
To change this setting:
- open the configuration of the email group used for the delivery;
- locate the default tracking preferences;
- disable open and click tracking;
- save the configuration.
![]()
The email group configuration applies to the entire delivery and does not distinguish between recipients based on their __clt value.
For emails sent through Marketing Automation, tracking can be enabled or disabled in the Send mail step for each email. The __clt field is not considered in this case either.
