By default, all web page links in emails sent are transformed into our tracking URLs. It means that a campaign event with the 'clicked' status is recorded only when a customer clicks the link and opens the corresponding page.
However, the 'Send email' links aren't converted into tracking links because they lead directly to an action in the customer's inbox. When you add these links to the template, they are formatted as follows:
mailto:email@email.comThis link opens a new email window in the customer's email client, allowing them to immediately send a pre-filled email to the specified address after clicking it.
Since the 'Send email' link doesn't open a separate webpage and performs an action within the customer's email client, click events on those links aren't tracked within the platform.
