DKIM record checker

What is DKIM record checker?

The DKIM record checker is a straightforward online tool designed to help you verify the status and configuration of your DomainKeys Identified Mail (DKIM) record. DKIM is a crucial email authentication method that helps protect your email sending reputation and prevent your emails from being marked as spam or phishing attempts.

You might want to use this tool if you've recently set up or updated your DKIM records, are experiencing email delivery issues, or simply want to confirm that your email authentication is correctly configured.

How to use DKIM record checker

Using the DKIM record checker is quick and easy. You just need two pieces of information:

• Domain Name: This is the domain name from which you are sending emails (e.g., yourcompany.com).
• Selector: This is a specific name or code provided by your email service provider (like Google Workspace, Microsoft 365, Mailchimp, etc.) that is used in your DKIM record. Selectors allow you to have multiple DKIM records for different purposes or services on a single domain.

Here are the simple steps:

1. Enter your domain name into the "Domain" field.
2. Enter the specific DKIM selector provided by your email service into the "Selector" field.
3. Click the "Check DKIM" or similar button.

The tool will then perform a DNS lookup for the specified domain and selector. It will report back whether the DKIM record was found, display the record's content (the public key), and indicate if there are any apparent configuration errors. This helps you confirm that your public key is correctly published in your domain's DNS records.

Use cases and applications

Checking your DKIM record is an essential step in managing your domain's email security and deliverability. Here are several scenarios where this tool is incredibly useful:

Setting Up a New Email Service

When you configure DKIM for a new email provider or marketing platform, you'll be given a selector and a public key to add to your DNS records. Use this tool immediately after publishing the record to ensure it's visible and correctly formatted in the global DNS system. This confirms your setup is complete and ready to authenticate your outgoing emails.

Troubleshooting Email Delivery Issues

If your emails are landing in spam folders or being rejected by recipient servers, a misconfigured or missing DKIM record could be the culprit. Use the checker to quickly rule out or identify DKIM as the source of the problem. A failed check points you directly to a DNS issue that needs fixing.

Migrating Email Providers

Switching email providers often requires setting up new authentication records, including DKIM, with a different selector. Before fully transitioning, use the tool to verify the new DKIM record is live and correct while the old one might still be active. This ensures a smooth migration without impacting email deliverability.

Regular Security Audits

It's good practice to periodically check your domain's authentication records, including DKIM. DNS records can sometimes be accidentally altered or deleted. Running a quick check with this tool ensures your critical email security measures remain in place and properly configured over time.

Benefits and features

The DKIM record checker offers several advantages:

• Simplicity: It provides a user-friendly interface requiring only your domain and selector.
