How to Set Up SPF, DKIM, and DMARC for Email Security
21/05/2025
SPF, DKIM, and DMARC are email authentication protocols that
protect your domain from spoofing and phishing.
SPF verifies sending servers, DKIM ensures email integrity,
and DMARC adds reporting and enforcement.
You can configure them in your domain’s DNS records—many
hosts offer simplified tools like hostizm.
Without these records, your emails are more likely to land
in spam folders.
Setting them up builds trust with ISPs and improves
deliverability for newsletters and campaigns.
