ESP - Wordpress Plugin: The Newsletter

A guide to generating UUIDs with the Newsletter Plugin

The Newsletter plugin offers personalization tags which allow users to pull in personalized campaign and user data. By using combinations of these variables, we can generate and pass unique identifiers (UUIDs) into the "key" parameters without the need for any javascript. For example:

{id} pulls in the subscriber's unique ID
{date_NNN} pulls in the current date formatted as a sequence of characters

By combining these tags, we can successfully create dynamic UUIDs and our "key" parameter values would therefore look something like this:

<a href="{id}{date_NNN}...
<img src="{id}{date_NNN}...

NOTE: the same tags should be passed into the "key" parameter values of both the click and image URLs just like we've done above.
