Hi Chris,
Welcome to the forum, and thanks so much for your report!
Ha, the classic: feature or bug?
In this case, it’s a feature. Please have a look at
/wp-content/themes/bricks/includes/integrations/dynamic-data/providers/base.php
Long story short: if you link to an email address, we add the mailto: automatically. If you don’t want this, you can use the :text filter such as {mb_ansprechpartner_email_6bs75cqxl5:text}, but then you have to add the mailto: manually. Alternative: Just leave out the mailto: and it will work as expected.
Best regards,
timmse
