Unsubscribe To ensure legally compliant communication, all marketing emails must offer recipients an unsubscribe option to prevent unwanted delivery. This is a fundamental principle of permission marketing.
Exception: Transactional emails do not need to include an unsubscribe link, as they do not contain promotional content. Further details can be found in the ECOS Guide(German) and on the Transactional Emails page.
Unsubscribed profiles remain in the pool but are no longer considered for mailings. For data protection reasons, it is recommended to regularly remove unsubscribed or unconfirmed profiles from the pool if there is no synchronization with external systems. When working with external systems, such as profile imports or automated interfaces, it is essential to clarify beforehand whether deleting the profiles in Evalanche will maintain data consistency.
Important!
There are target group statements with the ending "Without dispatch protection" ("Unsubscribed without send-protection" and "Permission (without protection)").
If one of these statements is used in a target group, the entire target group is no longer checked for unsubscribes or permissions when it is sent and unsubscribed or unconfirmed profiles become usable profiles that are also sent.
The Unsubscribe Process
When using {$DELETE_URL}, a personalized unsubscribe link is generated, including its assignment to the mailing/send, so that the unsubscription can be statistically recorded.
The unsubscribe link follows the pattern https://(Sending domain)/delete.php?sid=(Mailing SID),u=(Profile SID). Additional parameters (i=xxx,n=yyy) may be appended, but these are not technically relevant to the unsubscription process.
After successfully unsubscribing, you will be redirected to a confirmation page, which can be configured in the mailing or template settings, as shown in the screenshot.
This redirect link can also be used to initiate further processes; for example, data such as IDs can be passed via replacement variables.
Further information about replacement variables can be found here.
2-Click Unsubscribe
A 2-click unsubscribe allows users to unsubscribe with an additional step: via a logout page, to prevent accidental unsubscribes, for example, by security software. If you plan to use a custom logout page, you must ensure that the website contains a working unsubscribe link. An example of how to generate such a link using Tal can be found here.
The one-click unsubscribe link in the email header remains unchanged for legal reasons. The two-click unsubscribe option only applies to the variables {$REVOKE_URL} or {$DELETE_URL}.
Unsubscribe via List-Unsubscribe
Email providers like Google, Microsoft, and GMX offer their customers the option to unsubscribe from newsletters without having to open the email or search for an unsubscribe link.
For this purpose, a "List-Unsubscribe" entry is added to the header of the emails.
This List-Unsubscribe typically uses the system's standard unsubscribe process, meaning the same procedure is used as with {$REVOKE_URL}.
