Who this is for: Any small business that uses email for customer, supplier, or financial communication.
What to do
- 01Enable MFA and review forwarding rules on every important mailbox.
- 02Inventory legitimate services that send mail for your domain.
- 03Configure SPF and DKIM using your provider's current instructions.
- 04Start DMARC in monitoring mode and review reports before tightening enforcement.
What this does not cover
Email controls do not determine whether a message is legally required to be retained or whether a suspected fraud event must be reported.
