Email client with grouping by email?

Question

Email

1. Good afternoon, I'm interested in a desktop email client, where there is a grouping function by email.

Bat and thunderbird groups either by topic or by sender (but many people sending through different devices are named differently, so grouping by email is needed).

2. Are there any clients who display chat messages? (grouping by email but sent and incoming combined)

Answer 1

outlook 2010 and 2013 has groupings, including combining incoming and outgoing mail in one chain

Answer 2

Some nonsense.
Any mail program perceives exactly the emails of the addressees, not the names. Moreover, use contacts and enter for everyone all the options of emails that he uses and there will be no problems. (In any case, in my picture of the world, everything is exactly like this)
I haven’t used offline clients for 5 years, and it’s scary to think what’s there. After these questions.

Answer 4

Really weird question. No matter what email client I use, there is always the possibility of sorting by email, as well as filters, for example, all letters from employees *@company.com in a separate folder
