How Healthy is your Business Email Domain?

A healthy email domain ensures that your messages are delivered reliably — without being marked as spam or bouncing back. Checking your email domain health involves assessing various factors that can impact deliverability and security. This article will guide you to verify how healthy your business email domain is.

An email domain health check includes various elements such as authentication protocols, blacklist status and mail server configurations. If you neglect these factors, it could lead to email deliverability problems and potential damage to your organization’s reputation.

Key Elements of Email Domain Health Check

Authentication Protocols (SPF, DKIM, DMARC)

1. SPF (Sender Policy Framework): SPF prevents email spoofing by specifying which servers are authorized to send emails on behalf of your domain.
2. DKIM (DomainKeys Identified Mail): DKIM adds an encrypted signature to your outbound email, and allows the recipient’s mail server to verify the authenticity and integrity of the email.
3. DMARC (Domain-based Message Authentication, Reporting, and Conformance): DMARC works with SPF and DKIM to further prevent email spoofing, and provides reporting capabilities for monitoring. DMARC policy tells the recipient mail servers what to do with emails that do not pass SPF or DKIM validation.

Blacklist Status

Checks whether your domain name or IP address is listed on email blacklists. Some popular blacklists include SpamCop, SpamHaus and Barracuda.

Mail Server Configuration

Verifies that your mail server is configured correctly to minimize the risk of misconfigurations affecting email delivery.
