Why can't I see mailto links in my Link Report?
 
Recent security enhancements in Apple’s latest macOS versions mean that the link-tracking technology used by Mail Designer is no longer compatible with mailto: links. When a tracked mailto: link is clicked in an email on macOS, Apple’s security system may block the action and display the following message:
“This website has been blocked from automatically creating emails” To prevent this error from occurring for recipients, Mail Designer automatically disables tracking for mailto: link structures in email campaigns.

Technical explanation:

Mail Designer’s link tracking works by rewriting links so they first pass through a tracking URL before opening the final destination. This approach functions reliably for standard web URLs (https://), where the browser can safely redirect the request.
However, mailto: links behave differently. Instead of opening a webpage, they trigger the user’s default email application and attempt to create a new message. In recent macOS versions, Apple treats this behavior as a potential security risk when initiated via a redirected or rewritten link.
As a result, macOS blocks tracked mailto: links to prevent unwanted or automated email creation. Since this restriction is enforced at the operating system level, it cannot be overridden by Mail Designer.
To ensure a smooth and secure experience for recipients, Mail Designer disables tracking for mailto: links by default. These links will continue to work as expected, but clicks on them will not be tracked.
