How to take user feedback?

Hello 👋 everyone!

I am Heli, the maker of ContentCale.

ContentCale helps content creators generate their monthly content calendar for various platforms using AI.

Till now I got 100+ users to try out my tool. I mailed them to share their feedback but got no reply.

Is my product missing something? Can you please try it out and share feedback?

Or I am doing something wrong while asking for feedback.
