DKIM Test Results Explained

Our DKIM lookup tool analyzes your DKIM DNS records to produce various results. These results convey the information found during the checking process. Below you will find a detailed explanation of some possible DKIM test results:

Result: Valid DKIM Record

Checks-the-existence-of-your-published-SPF-record

Explanation: This means that your domain is correctly configured with DKIM, and the DKIM record published on your DNS is correct. You are looking for this result as it indicates that your domain is protected using DKIM authentication.

Result: Invalid DKIM Record

Detects-Multiple-Lookups

Explanation: This indicates the DKIM record in your DNS is invalid. This can happen due to a variety of reasons including syntax errors, incorrect formatting, or missing fields. The best course of action on getting this result is to create your DKIM records again using an automated online tool and republish it without trying to manually implement your record.
