The “DKIM not signed” error means your outgoing emails don’t include a DKIM signature. Without a valid DKIM record:
Email providers can’t verify your messages
Your emails are more likely to be marked as spam or rejected
To resolve this error, you’ll need:
Access to your email provider’s admin console such as Google Workspace, Outlook, or Zoho
Access to your domain provider’s DNS management console such as GoDaddy, Squarespace or Namecheap
📣 Note
HoneyBook checks and alerts you about DKIM issues, but fixes must be done in your provider’s settings. If needed, contact your email provider or domain provider’s support team.
Step 1: Enable DKIM in your email provider
Log in to your email provider’s management console
If you’re unsure who your email provider is, use an MX Lookup tool → enter your domain (everything after “@”)
Locate your DKIM settings or “Email authentication” section
Toggle DKIM on if it isn’t already
Copy the values provided, which usually includes a DKIM selector name and a public key (p=). You’ll paste these into your domain provider’s DNS settings in the next step.
Find DKIM setup instructions for your specific provider
Each email provider uses slightly different terminology and steps to retrieve DKIM values. Visit your provider’s help center or setup guide for accurate instructions. Keep in mind that instructions will vary depending on the provider.
You can try searching “Set up DKIM for [your provider name].” This will give you the most accurate, provider-specific steps and the DKIM value to copy.
Step 2: Add a DKIM record in your domain provider
Open your domain provider’s management console
If you’re unsure who your domain provider is, use a WHOIS lookup tool
Navigate to the page where you manage DNS TXT records
Create a new TXT record for DKIM. Here’s the typical format:
Type | TXT (don’t select DKIM) |
Name or host | DKIM selector provided by your email provider |
Value or data | Must include:
|
TTL (Time to Live) | Default, or set between 1800–3600 seconds |
Step 3: Save and verify
Save your changes in your domain console
Wait up to 48 hours for DNS changes to propagate
Run HoneyBook’s domain tester again to confirm the error is fixed
Optionally, use a third-party DKIM validation tool
Additional steps for high-volume senders
If you send more than 5,000 emails daily, Google and Yahoo’s 2024 deliverability rules apply to you. In addition to DKIM:
Add a DMARC record to protect against spoofing
Test your setup with a DMARC checker
