Email Health Check - MX/SPF/DMARC/DKIM

Q: What is SPF and why is it important?

SPF (Sender Policy Framework) defines which mail servers are allowed to send emails on behalf of your domain. An incorrect or missing SPF record can cause emails to be rejected or marked as spam.

Q: What is DKIM used for?

DKIM (DomainKeys Identified Mail) adds a digital signature to outgoing emails, allowing receiving servers to verify that the message was not altered and truly comes from an authorized sender.

Q: What is DMARC and what does it do?

DMARC tells receiving mail servers what to do with messages that fail SPF or DKIM checks (deliver, quarantine, or reject) and provides reports about email authentication issues and abuse attempts.

Q: Why do my emails end up in spam?

The most common reasons include: missing or misconfigured SPF, DKIM, or DMARC records poor sender IP or domain reputation unauthorized mail servers sending emails incorrect DNS configuration

Q: Is having only an MX record enough?

No. MX records allow you to receive emails, but SPF, DKIM, and DMARC are essential for proper email authentication and inbox delivery.

Q: Can I check any domain?

Yes. The tool works for any domain, regardless of where it is hosted or who provides the email service.

Q: Does this tool send test emails?

No. The check is 100% passive and based on DNS and reputation analysis. No real emails are sent.

Q: Are the results real-time?

Yes. The analysis is performed in real time, using the current DNS configuration of the domain.

Q: Is the tool free to use?

Yes. The Email Health tool is completely free and can be used as often as needed.
