Looking for Gmail based crm with low cost

I'm currently using streak free tier and they've decided to change to $60 us a month minimum. For what I do I only have a couple of inquiries a week at most I'm not paying that.

I'm looking at things like Hubspot but what I want is to be able to open an email and Gmail and from there go to a related email in the same deal without leaving the Gmail interface. I haven't found anything that can do this?

I mean is this why streak went from a $15 plan to $60 basic plan?
