Here’s what people have said about past builders:
The first CSV that came through was over 3000 new subscribers! Of those about half were already on my list which is an indication of how targeted the builder was to my genre. Over the course of six weeks, around 6000 email addresses came through. Of those, 3114 new subscribers completed my onboarding sequence and joined my list. I’m very happy with that result!

Grown with Hart is amazing! They netted me 2,200+ targeted subscribers! Would highly recommend them for NL building!

This was an amazing experience, my subscriber list grew by thousands of actual romance readers in my target audience. Highly recommend Grown With Hart services!
