Email Unsubscribe Setup/Editing
In Alerts settings it is possible to customize the messaging around the unsubscribe link included in Alerts Emails.
Add/Edit your own custom message to the text box and utilize the included unsubscribe_link button to insert the variable for where the unsubscribe link will be placed.
Once you have completed writing your unsubscribe message and added your unsubscribe link by clicking on it between the messages, use the lower section to generate the translated versions to be included in translated Emails.
If the purple button is still grayed out at the bottom of the page, make sure you have selected the Refresh all translations button in the bottom right corner of the box.
