Frequently Asked Questions
What is a DKIM selector?
A selector is a string used to point to a specific public key in your DNS. It allows you to have multiple DKIM keys for different sending services (e.g., one for Google Workspace, one for Mailchimp).
Why is my DKIM record returning "Not Found"?
DNS propagation can take up to 24 hours. If you just added the record, try again later. Alternatively, ensure you are using the correct selector name provided by your email service.
