I’ve done this in the past using Gmail. You pick a domain provider and get their email plan. Most offer both services. I’ve used name cheap.
Then in your regular Gmail account you can configure the IMAP settings from the domain registrar to receive the email from that inbox. Then in Gmail find the settings where you can send as another address. This lets you use that new address in our outbound mail. From there I just auto label the incoming mail to help sort the two addresses.
Now you should have your regular Gmail and your new novelty email all in one place.
