MX records tell other servers where to deliver mail for your domain. Your email provider lists the exact records to add.

No MX record, so the domain cannot receive email
Why it matters. Without an MX record, mail sent to your address bounces or is guessed from the website's address. Mailbox providers also trust domains that receive mail more than send-only ones.
How to fix it.
- Add the MX records your email provider lists (Google Workspace, Microsoft 365, Zoho and your host all publish them) in your DNS zone.
- If the domain never receives email, publish a null MX ("0 .") so senders fail fast instead of retrying.
