Integrated Referral System

I’m a BeeHiiv user and part of my new subscribers come from a referral system at the end of the newsletter.

I tried integrating sparkloop but it required a lot of heavy lifting, and I’d like not to pay for an external system tens of dollars a month for that feature.

Most of other referral systems have lacking docs, and it seems to be an increasing norm with newsletters.

This would be amazing! Thanks.
