💡 What is DKIM?

DKIM (DomainKeys Identified Mail) is an email authentication method that:

• Digitally signs your outgoing emails using a private key

• Allows the recipient’s mail server (like Gmail) to verify the signature using your public DKIM key in DNS

• Confirms that:

  • The email really came from your domain

  • It wasn’t altered in transit

✅ Why DKIM is Necessary

Without DKIM:

• Spammers or attackers can forge your domain to send phishing emails

• Your emails might get flagged as “suspicious” or “spoofed”

• You lose control over your domain’s reputation

With DKIM:

• Your domain says: “I vouch for this email”

• Email services (like Gmail, Outlook, Yahoo) trust your messages more

• It improves deliverability, helping you land in the inbox, not spam

📢 Why Google Requires DKIM (as of February 2024)

Google (Gmail) introduced stricter rules for bulk email senders and even regular domains that send to Gmail accounts.

Here’s why:

🚫 1. Combat Spoofing and Phishing

• Without DKIM, bad actors can pretend to be your domain

• Google wants to protect users from fake messages

📬 2. Improve Email Trust and Deliverability

• Google is pushing for authenticated email across the internet

• DKIM, SPF, and DMARC help Google decide which emails are safe

📉 3. Unverified Emails = Lower Reputation

• If you send unauthenticated emails to Gmail users, Google may:

  • Mark them as spam

  • Or block them entirely

⚠️ What Happens If You Don’t Enable DKIM?

• Your emails may be flagged as unverified

• You risk inbox placement issues, even if you’re sending legit content

• Gmail may eventually block your domain for sending unauthenticated mail

✅ Summary

DKIM is essential for protecting your brand, improving email deliverability, and complying with major providers like Google.

Think of it as sealing your letter with a signature. Without it, Gmail might toss it straight into spam — or reject it entirely.

✅ Steps to Enable DKIM in cPanel:
Log into your cPanel account.

Go to the Email section and click on:
???? “Email Deliverability” (or sometimes “Authentication”, depending on your cPanel version).

Locate your domain in the list.

Under your domain, check the DKIM status:

If it’s not enabled, you’ll see an option to “Repair” or “Enable” DKIM.

Click “Enable” or “Repair”, and cPanel will:

Generate the necessary DKIM DNS record (a TXT record).

Attempt to automatically add it to your domain’s DNS zone (if your DNS is managed through the same cPanel/host).

✅ You should see a confirmation message like:
“DKIM is enabled for this domain.”

???? Note:
If your domain’s DNS is managed elsewhere (like Cloudflare or a registrar like GoDaddy), you’ll need to:

Copy the DKIM TXT record shown in cPanel

Add it manually to your external DNS provider

???? To Verify:
After 15–60 minutes (depending on DNS propagation), you can verify your DKIM record with  a tool like:
