This is what I’m doing. I recently switched from the email service offered by my web host to Zoho Mail. I pay them $12 a year for a couple of gigabytes storage (which isn’t a whole lot but enough for me and I’m cheap).
As someone else says elsewhere, as well as changing the MX records to the new server, you need to add SPF, DKIM and D-MARC records in your DNS to ensure mail you send is accepted by the receiver’s mail server.
the word’s not useless, it’s just that its meaning has evolved to encompass pretty much all authoritarianism, rather than just a specific subset of it.
