If you manage personalized content on your site or in your database, you may want to share a link with subscribers that's specific to their account with you. For example, you might share a personalized coupon with a single recipient, so it can't be shared with others.
As long as you store unique identifier information for each subscriber in your database, you can do this with merge tags.
Below, you'll learn to create a list field and merge tag for a subscriber's unique link ID, which can be added to any valid URL in your campaign.
Unique URL Example
Conditional merge tags don't work with unique URLs. If a conditional merge tag is used in a URL, the URL will break when the campaign is sent to the list.
