Which services do you use to speak to your users?

I'm looking for some services that would make this whole process easier.

I've stumbled upon Instabug which has some pretty cool features where you can post an in-app survey, follow up with in app chats etc. I'd imagine this would have a much better conversion rate than just emailing. But its crazy expensive for an indie dev.

Are there any services dedicated to this problem that's friendly to indie devs?
