The shopping cart software I personally use to create funnels, I got Thrivecart and Thrivecart Pro for a one time fee and it just keeps getting better.
Recently they added Learn and Learn+ to their offering making it a formidable bit of software. Easily able to handle any of your book funnel and upsell delivery all within 1 software.
4. Thrive Architect
Thrive Architect was the first drag and drop page builder for wordpress.
Personally I like to use it on dedicated course websites (I use Divi for my landing pages most of the time) coupled with Thrive Apprentice that way you can leave them on autoupdate and you shouldn’t have to many problems.
Groove Funnels would be my choice if I didn’t already use Thrivecart for my business.
I have messed about with it a little bit and it looks like an incredible offer. The experience the founders have with this type of marketing and the 1 time fee should make this package a no brainer.
I may do a full review in the future.
