The user and user device pixelation link has several possible uses. It is used to validate and acquire user device and subscriber, to launch a campaign after visiting the link, as well as for communication through an external channel (any offline media). 

For example, you can launch a campaign with QR codes, which validates the presence of each of the invited guests from a list. 


Options in the link parameters

You have the following options in the parameters of the user and user device pixelation link: 

  • email - this option is compared (required) to verify the subscriber 
  • subscriber_id - this option is compared (required) to verify the subscriber 
  • tag - this option assigns tags to the subscriber based on which they enter a specific segment of the campaign 
  • referral - through this option is transferred the source that is set

Example scenario

Here we will look at the example QR codes campaign to validate the presence of each of the invited guests from a list. 

1. A marketer imports subscribers via CSV or API into CloudCart. 

2. The list is used to generate QR codes for scanning by the end subscriber. 

3. Every QR code is created based on a link leading to the campaign site, which contains several parameters: 

  • customer email
  • subscriber id
  • tag
  • referral

4. Once the user has received their QR code, they can scan it with their device so that it can be identified by the system and respectively marked that they have scanned the code. 

5. After scanning, the user enters a segment by the chosen tag - tag1 and everyone who scanned the code receives a notification from the campaign.
