🔒 This feature is available to Kit customers and users with an existing Referral Program.
Referral links are where the magic happens. SparkLoop autogenerates a unique referral link for each of your subscribers and stores them in a custom field called RH_REFLINK.
How it works
Each subscriber gets a unique referral link they share with friends. Every click takes that person to your signup page, earning the advocate referral points. Set your referral link destination URL in Campaign → Referral links URL → Save.
Permanent referral links
SparkLoop referral links are permanent — fixed for each subscriber. This means instant URL updates without re-sending emails, better analytics, shorter links, and no broken links if you change your landing page.
Displaying unique referral links in your emails
Use the RH_REFLINK merge tag (with the correct syntax for your ESP) wherever you want the referral link to appear in your email.
Generating social sharing links
The easiest way is to use our Visual Builder. If you're not using the Visual Builder, go to Referral Section → design your own referral section → step #4 and use the Referral Sharing generator to create your links.
How to add UTM parameters
Add UTM parameters directly to the merge tag as you would with a normal link. For example in ConvertKit:
{{ subscriber.rh_reflink }}?utm_source=facebook&utm_campaign=paid-ads
SparkLoop will automatically pass over any query parameter you send. If you'd like to create custom links, read these instructions.
