Managing tracking consent with Send

Tracking consent management can be enabled separately for each Send user database. The feature stores and applies each recipient’s preference for individual open and click tracking.

Configure

Enable tracking consent management on an existing database

To enable tracking consent management:

1. Go to Configure > User DB.

2. Select the relevant database.

3. Click Edit.

4. Select the Enable consent tracking management option.

5. In the Default value for existing contacts drop-down menu, select how to set the consent field for contacts already present in the database:

   • Tracking not allowed (0);

   • Tracking allowed (1).

6. Click Edit to save the changes.

   

warning

Tracking consent management must be enabled separately for each user database.
Once enabled, the feature cannot be disabled.

The __clt field

Enabling the feature adds the __clt field to the database. This field stores the user’s tracking preference.

The field can have the following values:

Value	Behavior
__clt = 0	The communication is delivered without individual open and click tracking.
__clt = 1	The communication is delivered with individual open and click tracking enabled.

The field’s default value is 0.
When enabling the feature on an existing database, the customer can select the initial value to assign to existing contacts, as described in the previous section.
The customer is responsible for ensuring that the __clt value is consistent with the preference expressed by the user and for updating it whenever that preference changes.

Manage the tracking preference link

After the feature is enabled, Contactlab provides a dedicated link for managing tracking preferences.
This link is separate from the unsubscription link and allows recipients to change their tracking preference without stopping the delivery of communications.
To retrieve the link:

1. Go to Configure > User DB.
2. Select the relevant database.
3. Click Edit.

The link uses the following syntax:

$#subscription_url_base#$/tp/d/${encoded_user_data_tracking}$/k/${form_verification_code_tracking}$/lang/it/ .

Its structure remains unchanged. At delivery time, Contactlab automatically populates the parameters required to identify the recipient and update the associated preference.

info

Insert the link into the communication without changing its placeholders. Do not manually replace the dynamic parameters.

To display the page in one of the available languages, change the code after the /lang/ parameter.

For example:

• it for Italian;

• en for English;

• fr for French;

• es for Spanish.

Manage consent in subscription forms

When tracking consent management is enabled, the corresponding field also becomes available in the subscription settings.

To access the configuration:

1. Go to Configure > Email groups.
2. Open Subscriptions.
3. Click Manage.

The tracking preference field is added to the subscription page and form according to the selected configuration.

Tracking behavior

For Marketing deliveries, Contactlab uses the __clt value to determine whether individual tracking should be applied to 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 delivery type is defined under Create > Email campaign > Delivery Parameters.

warning

The __clt field applies only to Marketing deliveries.
For Transactional deliveries, the __clt value is not considered. Tracking behavior therefore depends on the configuration associated with the transactional delivery, regardless of the preference stored in the field.

Insert the link into a communication

When creating an email delivery, you can insert the tracking preferences link using a preset text.

In the Message content step:

1. Open the Preset texts menu.
2. Select Manage tracking preferences.
3. Insert the text at the desired point in the communication.

The preset text automatically adds the link to the tracking preferences page to the HTML.

Tracking preferences page

When the recipient clicks the Manage tracking preferences link in the communication, a dedicated page is displayed where the tracking preference can be changed.
Saving the preference updates the __clt field associated with the recipient. This change only affects tracking: the recipient will continue to receive communications unless they unsubscribe separately.
