Whether you’re a business owner, IT admin, or security expert—checking your DKIM setup protects your emails from spoofing, phishing, and tampering.
What is DKIM and Why It’s Important
DKIM (DomainKeys Identified Mail) is an email security feature. It adds a digital signature to each email you send.
This signature is matched with a public key in your domain’s DNS. If the keys match, the email is considered real and unchanged.
DKIM helps:
- Confirm that the message is from your domain.
- Prove that it was not changed during sending.
- Build trust with email servers.

Why You Should Check DKIM Regularly

DKIM vs SPF vs DMARC – What’s the Difference?
- SPF: Checks if an IP can send email for your domain.
- DKIM: Confirms the email is not changed and is from your domain.
- DMARC: Uses both SPF and DKIM to protect your domain and give reports.
For the best protection, you should use all three.

FAQs
Q1. Can I check DKIM without the selector?
No. You need both the domain and selector to perform a check.
Q2. What happens if DKIM is missing?
Your emails may be marked as spam or rejected.
Q3. Is DKIM needed for DMARC?
Yes. DMARC works only if either SPF or DKIM is aligned. It’s best to use both.
