Is there a CRM with an email client?

Question

CRM

Hello!
I use the Trello system for managing clients - a very cool and simple system.
It would be very convenient if there was such a CRM, similar to trello, where correspondence with each individual client could be moved through the stages just like in trello and respond (and receive answers) directly from crm.
Maybe there is such a thing, please advise =)

Answer 1

AmoCRM seems to be able to do this.
