For mail this won’t work.
For one, you have to now think about dynamic dns because you have your one static ip and then whatever ip your data backup will rollover onto. This isn’t ideal. Probably going to ruin any trust your domain will have.
Second, there is no way you’re getting a reverse PTR record setup to work in this config.
So, no, it’s not gonna work.
It may work fine if you have random services, but tbh I don’t ever want to use or deal with a ddns service myself.

You do realize your DNS MX records can point to both IPs, and your primary connection just has a higher priority number, right? This is 2025, dns is outright expected to have multiple IPs behind in varying levels of priority and availability. As for DDNS constantly rolling things, I’ve got, as I said, spectrum residential and my IP address has changed once in half a decade. Finally, I literally mentioned that there were other ways around this, like an external proxy server on a static IP. Throw it on DO or something.
