What is an apex domain?

It is the root domain (e.g., example.com) without any subdomains like www. or mail.

Do I need records at the apex domain?

Yes, if you use @ addresses (like user@example.com), you must have MX and SPF records at the apex.

Standard DNS doesn't allow CNAMEs at the root; you must use an A record or an ALIAS record from your provider.

The apex is the root domain, like example.com, without any subdomain prefix.

Usually no with standard DNS. Many providers support ALIAS or ANAME as an apex-compatible alternative.

Verify records for your root (apex) domain for proper routing and auth.
