How we validated our SaaS product without building it

When we first started sendwithus we had no idea what we were going to build. We knew that transactional email was a problem worth solving and we were determined to build a great solution.

Our first hurdle was figuring out what potential customers wanted. To find an answer, we ran several “lean” product experiments to identify early adopters and measure what features they wanted most in a transactional email service.

This post revisits one of those early experiments! =]
