Maximizing Referral Prizes to Boost Subscriber Growth

Referral prize ideas/ help I have 5 companies that are willing to partner and provide giveaways for referral milestone achievements. I only have a once/month newsletter (for now), but I want to leverage these prizes asap to grow my subs. Is there a way to use beehiiv's referral system/tracking outside of the newsletter embed? Or will have to figure out a workaround? Any advice would be greatly appreciated.
