Yes, as @EinsteinsHund says. Good bet your DNS provider also offers email services.
But, let me offer a warning.
I have had exactly the service you seek for the last couple+ decades. I had a personal / business domain through Brand X domain registrar / DNS provider / etc. and also used their email services to provide me with several email boxes at e.g. blahblah@LSLEnterprises.com. Meanwhile I never had a website at www.LSLEnterprises.com. (that’s a fake name, not my real one, but you get the idea.)
Easy peasy, and $50/year bought me a scad of email boxes and plenty of email storage. Plus the small fee to keep the domain alive & publish the DNS pointing to them.
The problem was that the registrar / DNS provider was unable / unwilling to properly configure the necessary modern anti-spam entries in DNS for my domain. That is SPF, DKIM, etc. And they prevented me from doing so either.
As time went on from 2000 to now, the practical result is that increasingly Gmail, AOL, Yahoo, and the various Microsoft domains such as Outlook.com, msn.com, hotmail.com, and Live.com all rejected nearly all my emails to them, assuming they were spam. Only other tiddler ISPs like my own or corporations like my bank or employer would accept emails from LSLEnterprises.com. And sometimes not even them. With no notice of course; nobody auto-replies to suspected spammers anymore telling them they’ve been blocked. Your email is simply black-holed and you’re none the wiser that nobody ever saw it. That was bad.
By about 2020 it had became intolerable. Well over 80% of my emails simply disappeared into nowhere because all the big suppliers always assumed I was a spammer.
What I ended up switching to was a service that MSFT had then but no longer offers where I could rig up MS Exchange services through their cloud via Office 365 and point the LSLEnterprises.com domain to them via a different domain registrar (Godaddy) than the one I had used. They (MSFT) had partnered with Godaddy exclusively to know how to rig up SPF, DKIM, etc., so they pointed properly to MSFT’s servers and suddenly my emails got through to everybody.
Once this was in place I abandoned the DNS & email provider I had used for the last 20 years.
What a relief.
If I had to do it over again starting now I would seriously question the idea of having a personal domain versus just using LSLGuy@gmail.com or whatever. The unprofessional “stigma” of having an email address at gmail, live, outlook, or whatever is not what it was back in 1995.
My advice is that if you don’t already have an email or web presence at e.g. FCM.com, then don’t start one. If you are creating a significant business that’s different.
But for personal or family email, or a couple-person hobby/business, just don’t bother. Nobody today scoffs at e.g. FCM@Gmail.com like they might have 15-20 years ago. Nobody. You’ll be much happier at all the trouble you avoid.
