Our #1 source of subscriber growth has been through word of mouth and referrals, and Viral Loops has been crucial for tracking and attributing rewards as we’ve scaled from zero to tens of thousands of subscribers.
Very easy to setup, quick support response time as well. The product works incredibly.
Viral Loops has allowed us to build a referral program that gives our readers that extra incentive to spread the word of The GIST.
Roslyn McLartyCo-founder, The GISTExceptional customer service. A handy product in my modest startup waitlist marketing stack that plays a key role.
Shopify App StoreWow this app actually works! Unlike the other apps of this kind this is very easy to use.
Our readers naturally shared our content with their friends, but now we can measure this impact, reward our biggest cheerleaders.
Great product, easy to use, value for money. I’ve been using VL more than 10 years…
