Sometimes you may see a link in your email that isn't decorated when you mouse over it. That same link isn't tracked when you click it.
Check that there is a link
The most common solution is to add a link to the email. Many email clients will automatically add links to when the text looks like a URL. For example, here's a link as it was typed in an email:
But Outlook renders that text as a link:
To fix this, edit the email and add a link to the URL by highlighting the text and clicking the link icon in the HTML editor:
Check the <a> tag
If you edited the HTML, check to make sure it's correct. Check if the:
- href is enclosed with quotes
- <a> is opened and closed correctly
Check for class="mktNoTrack"
If you edited the link with class="mktNoTrack", the link will not be decorated by Marketo. You'll have to remove that class from the email template or email body, depending on where it is.
Validate your email HTML
As an additional check, you might want to run the HTML through a validator; HTML errors can cause links to break among other problems.
Download the HTML for your email with the Download HTML button in the HTML Tools menu. Then run the HTML through HTML Tidy. You should address the issues it discovers as they may be responsible for the bad link.
