DNS Changes That Can Break Email

Email is highly sensitive to DNS configuration. Certain changes can stop email delivery immediately.

High-Risk DNS Changes

Deleting MX records
Changing nameservers without recreating email records
Removing SPF or DKIM records
Pointing MX records to the wrong server

Safe Practices

Verify MX records before saving changes
Do not remove existing email records unless replacing them
Confirm DNS zone after nameserver changes

If email stops working after DNS changes, revert immediately if possible.
