Are users tired of filling feedback forms?

So we've started our business a bit more than a month ago and it's going(ish). subscriptions are coming in at a very slow rate, nothing to be able to live from but better than nothing i supose at this moment.

There is this one thing that's troubling us, how do you make users to give more feedback?

We've tried several things like:

- Sending newsletters with surveys attached - direct outreach on our support channel (crisp) - Twitter comments and direct messages - Reddit messages - Hotjar surveys - ...

Most people give a "great", some give a 0 when i ask them to rate (without further explanation). I've optimized a lot of hotjar surveys to poll for more feedback when they give 0 or follow up messages to not just get "great". But it seems like almost nobody feels like filling it in, are users tired of giving feedback?

What are your thoughts? How can i increase this conversion rate to be able to iterate properly.
