Problem / Idea validation

1. So one thing I've definitely struggled with during the various side projects I've worked on is product market fit. Knowing whether or not I was on track or building something that actually solved a problem wasn't easy to figure out.

Luckily, superhuman / Sean ellis provided a pretty solid framework for determining this. The problem with this though is that it's a lot of manual work and typically only constitutes validation at a single point in time. I want to solve this problem through in-app surveys/questionnaires and then auto-analyse the data for the users (although this is solution space so more focusing on the actual problem right now). Currently validating this idea via twitter ads and a rough landing page thrown together using Landen - view it here: Validation Landing Page

2. The next problem I faced is sending out onboarding/welcome email flows to new users designed to either convert, up-sell or get them using the product. The problem for me, was that I

• Didn't know the best / cheapest platform
• All the platforms were incredibly complex with all these different logic flows
• I didn't know the right copy to use or even how many emails to send in the flow
• I didn't want to spend a lot of time doing the above

This problem above I decided to park for the time being, although I did get some success when validating this idea, I had about 11 people enter their email on the waitlist for a product which solved all those problems (super simple, easy to use email automation platform, no complex flows, pre designed sequence etc.) which was a conversion of about 9% (the landing page was literally about 10 lines on a blue background)

My question is, is this a problem for anyone else? And if so, would you pay for a solution?
