How to connect a domain to 2 different mails?

Question

Mail server

What is: a domain connected to google mail
Task: simultaneously connect a domain to google mail and yandex.
Why: Google is completely satisfied and even more, but free places are limited, and expanding is quite expensive.
I assume that you can connect to some kind of common mx records, and from them already distribute to two different mails. Or is it not possible at all?
Thank you.
