MailScanner detecting a "fraud attempt" in Marketo links

Hi all,

I've just seen one of our emails having arrived to our lead like this:

Has anyone faced the same thing before - does MailScanner block just any links or is there any specific criteria? Can I fix it on my side or is this beyond my control?

You must make sure that the inner text of a link (<a> tag) does not echo the original href of the link, because Marketo will rewrite the href and make it look like you're trying to fool the recipient.

Let me give an example. In an orignal email, this link:

  <a href="http:​//example.com/mypage.html">http:​//example.com/mypage.html</a>

will be rewritten to the bounce off the tracking server:

  <a href="http:​//go.example.com/randomcode123456">http:​//example.com/mypage.html</a>

and that looks malicious.

While using friendly text:

  <a href="http:​//example.com/mypage.html">Click here</a>

won't give the same impression to the scanner, because there is no URL-like text.
