What is the best way to integrate email correspondence into your CRM?

Question

CRM

You need to implement email correspondence with customers on orders in your CRM.
So that letters are tied to a specific order and correspondence can be conducted inside CRM.
Are there any suitable php solutions for this?

Answer 1

vTiger, SugarCRM
but you need to twist everything, of course, far from the box
if not PHP - Streak

Answer 2

Misunderstanding! Correspondence is conducted with the Client, respectively, and the history of correspondence is also tied to the Client.
As I understand it, CRM needs a built-in email client. In this case, it is better to consider CRM with a built-in mailer than to look for developments and developers.
