SPF, DKIM and DMARC are DNS records that prove your emails are genuine, which greatly improves deliverability.
- SPF lists the servers allowed to send mail for your domain.
- DKIM digitally signs your messages.
- DMARC tells inbox providers what to do with messages that fail the checks.
In cPanel, the Email Deliverability tool can add and repair these records automatically. Our support team is happy to help you configure them.
