DLL or Dynamic Link Leaders are usually used in Transact emails but in certain circumstances you may need to use a DLL Link within Acoustic Campaign such as for example pulling a link from a relational table into your email.

However you use the DLL Link, you now want to be able to build a query using the Has clicked a link in a mailing operator, but you see that the query does not see the DLL link(s) in the email.

It is not possible to pull in DLL links into these types of queries.

The reason for this is because only tracked links are visible to this type of query and by necessity you have to set your DLL link to be non tracked as in the following example:

<a href='' xt='SPNOTRACK>Click this DLL Link Here</a>

The URL has to be set as SPNOTRACK because we are constructing the entire tracking code manually and therefore bypassing the normal Acoustic Campaign process and going direct to the link server.

If you set this to be a tracked link, then Acoustic Campaign alters the code on sending and breaks the URL. This results in directing the link to the anti spam page.

However there is still a possibility to get the information you require into a query by taking a different approach.

If you have web tracking code on your web site, you could instead use Web Site Behavior and leverage the Has Viewed Web Page or the Has Triggered Custom Tracking Event behaviors.
