How to setup MX for mailgun and zoho?

Question

Email

There is a domain, there is a connected zoho mail. There is also a connected mailgun.
mailgun requires mx records mxa.mailgun.org and mxb.mailgun.org with priority 10 and 10
zoho also requires 3 mx records, but with its own servers with priorities 10, 20 and 50
i.e. mxa.mailgun.org 10 and mx.zoho .com 10 - can't coexist together, something will get stuck. Even in the control panel, they cannot be added at the same time.
How can I set them up, what should I use? Only one thing?

Answer 1

The mail server for incoming messages (MX records) can be only one service: either one or the other. If you register different services at the same time, then letters will come to different services, but not duplicated, namely, they will come here and there.
Priorities basically work: they try to deliver letters to the server with the lowest priority. If the connection fails, an attempt is made to another server in the list.

Answer 2

these are not requirements, but recommendations, the mail server that really should work for you should have a smaller value, for example 1 and 100 will be after it.
That's all
