DKIM Record Generator Tool
Create DKIM records to authenticate your cold email sends. Generate properly formatted DKIM records that cryptographically sign your emails and improve authentication and deliverability.

How to Use the DKIM Record Generator
Follow these simple steps to generate DKIM records for your domain:
Enter your domain
Type your domain name (e.g., example.com) into the input field. Do not include "http://" or "www."
Click Generate DKIM Record
Click the "Generate DKIM Record" button. The tool will create a DKIM key pair (public and private key) and generate the DNS record.
Copy the DKIM record
Copy the generated DKIM record. You'll also receive the private key that your mail server will use to sign emails.
Add to your DNS and configure mail server
Add the DKIM record to your DNS as a TXT record with the format selector._domainkey.yourdomain.com. Then configure your mail server to use the private key to sign outgoing emails.
Why DKIM Records Matter for Email Authentication
DKIM records provide cryptographic proof that your emails are authentic and haven't been tampered with. They use public-key cryptography to sign your emails, allowing receiving servers to verify the signature and confirm the email came from your domain.
- Cryptographic authentication proves emails came from your domain
- Prevent email tampering by detecting if messages were modified in transit
- Improve deliverability by building trust with email providers
- Enable DMARC policies which require DKIM (and SPF) to function properly
- Protect domain reputation by preventing spoofing and phishing
How DKIM Record Generation Works
Our DKIM record generator simplifies the process of creating DKIM records:
- Generate key pair: The tool creates a public/private key pair using cryptographic algorithms
- Create selector: Choose or generate a unique selector identifier for your DKIM record
- Format DNS record: The tool formats the public key into the correct DNS TXT record structure
- Add to DNS: Copy the generated record and add it to your domain's DNS as a TXT record
- Configure mail server: Set up your mail server to use the private key to sign outgoing emails
The generated DKIM record follows RFC 6376 standards and includes all necessary tags for proper email authentication.
