Create a DKIM DNS Record
Customize the options below to generate a DKIM record, which will be shown in the input field above.
This tool can be used to create DKIM DNS records, which together with a signature header can be used for authorizing emails.
When setting up DKIM, you must first generate a public/private key pair. The private key is signed with the email message and should be automatically included in the DKIM-signature email header, while the public key should be pasted here in the DKIM DNS record, so that other email servers can verify the signature.
Using DKIM prevents your emails from ending up in the receiver's spam folder. It is recommended to also set up SPF (to authorize certain IP addresses to send mail) and DMARC (to specify how to handle failed validation), to minimize the risk of getting your emails flagged as spam.
This tool only helps with setting up the DNS record. The DKIM-signature email header should be automatically set by your email provider when sending mails.
