SPF and DKIM help prove your emails are legitimate. Without them, messages may land in spam or fail delivery.
1

Enable DKIM and SPF in cPanel

In cPanel, open Email Deliverability and ensure DKIM and SPF show as enabled for your domain.
2

If DNS is external, copy the required records

If your DNS is managed elsewhere, cPanel will show the required DNS records.Copy those records into your DNS provider (usually as TXT records).
3

Add a basic DMARC policy

A DMARC record improves deliverability and gives you reporting.Start with a monitoring policy (not strict enforcement). Example record:
_dmarc  TXT  "v=DMARC1; p=none; rua=mailto:[email protected]"

Notes

DNS changes can take time to propagate. After updating records, test again later.
