Hello,
Thanks for contacting us.
If the ‘another_tag’ variable is not added, there could be different reasons. One possibility is that the callback function is not returning the expected value. You may want to double-check the implementation of the callback function to make sure it is returning the correct value. Another possibility is that the template file itself may not be using the ‘another_tag’ variable, so it may not be visible even if it is added to the $vars array. You may want to check the template file to make sure it is using the correct variable name.
The ‘another_tag’ variable should be available in the $vars array, but it may not be displayed in the variable list of the email template page by default. You may need to add it manually to the list of available variables, depending on the wpdm. The specific user ID that the notification is referencing may or may not be available depending on the context in which the notification is triggered. If the user ID is available, it may be passed as an argument to the filter hook, or it may be available through a global variable or function provided by the plugin or system. Consult the documentation of the plugin or system to see if there is a way to access the user ID. If you are not sure, you may need to contact the developer or support team of the plugin or system for assistance.

Tanvir
