A guide to generating UUIDs with Emma

Emma offers tags which allow users to pull in personalized campaign and contact data. By using combinations of these tags we can generate and pass unique identifiers (UUIDs) into the "key" parameter without the need for any javascript. For example:

[% member:member_id default="email" %] pulls in the contact's ID
[% date:day %] pulls in the numerical day of the week

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

<a href="[% member:member_id default="email" %][% date:day %]...
<img src="[% member:member_id default="email" %][% date:day %]...

NOTE: the same tags should be passed into the "key" parameter values of both the click and image URLs
