Question 1

What does the DNS checker analyze?

Accepted Answer

Our DNS checker validates your SPF, DKIM, and DMARC records. It checks for proper syntax, identifies configuration issues, and provides actionable recommendations to improve your email authentication setup and deliverability.

Question 2

How often should I check my domain health?

Accepted Answer

Check your domain health after any DNS changes, when adding new email sending services, or at least quarterly. Regular checks help catch misconfigurations early before they impact your email deliverability.

Question 3

Why is email authentication important?

Accepted Answer

Email authentication (SPF, DKIM, DMARC) proves that emails from your domain are legitimate. Without proper authentication, your emails are more likely to land in spam, and attackers can spoof your domain to send phishing emails to your contacts.
