A guide to generating UUIDs with Sendlane

Sendlane offers personalization tags and custom fields which dynamically pull in personalized campaign and user data. By using combinations of these variables we can generate and pass unique identifiers (UUIDs) into the key parameter without the need for any javascript. For example:

VAR_FIRST_NAME   pulls in the current day
VAR_LAST_NAME   pulls in the current month
VAR_SIGNUP_IP  pulls in the recipients email address

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


Custom fields could also be created and added to the default personalization tags above to ensure each key value is unique.

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