Free crm with email communication from customer section

Hi, Really appreciate if you have any recomendation.

I just have company list as a prospect list.. Gradually i will add email info, most of them i need to contact with them through their contact form or customer care number, few of them through email, i need to track all the conversation except phone call, for phone call will keep notes in crm.

For email able to sent from crm individually from template,i wanna see conversation later, and automatically show leadwise inside crm.

I know its tough to get this feature in free crm. Appreciate if you know something free or less then 10$ solution.
