This sometimes happens if you're hosting a site on cPanel if you have your email hosted outside of cPanel itself. By default, cPanel assumes that domains that are hosted locally (on the account) also have email set up on the account. This is part of the account's MX Entry settings. If you are hosting your email outside the cPanel account (with another provider, on Workspace Email, on Office 365, etc.) you'll need to update the MX Entry setting to be "remote" as opposed to "local". For more on that, you can read this article.
