The four settings we check
Together they decide whether email providers trust mail from your domain and block fakes.
- Receiving email (MX)
- Tells the internet where to deliver your incoming mail. Without it, you get no email at all.
- Approved senders (SPF)
- A list of the services allowed to send email as your business.
- Email signature (DKIM)
- A hidden digital signature that proves an email really came from you.
- Blocking fakes (DMARC)
- Tells Gmail, Outlook and others what to do with emails that fail the checks above.
