HTML Ad Unit ESP - Second Street

A guide to generating UUIDs with Second Street

Second Street offers tokens which dynamically generate campaign data. By using combinations of these tags we can generate and pass unique values (UUIDs) into the "key" parameter without the need for any javascript. For example:

{{System.Random1}} generates a random number
{{User.UniqueId}} user's unique Second Street ID

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

key={{System.Random1}}{{User.UniqueId}}

This is one of many possible variations. You can use whichever tokens you'd like just as long as the key parameter value (UUID) is unique to each email recipient and email campaign.  


NOTE: the same UUID must always be passed into the key parameter of both the anchor and image tag
