How to Add a DKIM Record to Namecheap - Step-by-Step Guide

Without DKIM, hackers can alter the content of an email for fraudulent purposes.

Therefore, DKIM records play a vital role in establishing trust with email servers.

If you’re doing email outreach, you need DKIM.

It not only increases your open rates but also improves security.

If Namecheap is your domain provider, follow our guide below to set up a DKIM record for it.

DKIM Ins and Outs 🔣

DKIM is an email authentication method that allows email servers to verify the origin of an email.

DKIM helps email servers answer the question: Is this email coming from the domain it claims to be coming from?

The authentication mechanism also verifies that the email’s content hasn’t been altered while being transmitted.

For the authentication, two keys are used: a public one and a private one.

The public key is automatically added when you add your DKIM record to your DNS. This public key is shared with email servers.

The private key works differently as it is used to sign outgoing emails. The private key must remain private to ensure DKIM’s security.

If an email server can successfully decrypt the digital signature created by the private key and it matches the email’s content, then authentication occurs.

But what if an email fails authentication? It can either be delivered normally, get sent to spam, or get rejected altogether.

What to do with unauthorized emails is determined by another DNS record called DMARC.

Steps to Add DKIM to Namecheap 🚶‍♀️

Generate your DKIM

You need a DKIM to add to GoDaddy. Usually, you can generate one in your email service provider account, i.e., the tool you’re using to send email.

  1. Go to your email service provider’s domain settings
  2. Look for domain or email authentication settings
  3. Go to “DKIM settings” or similar. This could also be named “DKIM,” “DomainKeys,” or “Email Authentication.”
  4. Now look for a button that says “generate DKIM keys” and click on it. If you can customize your DKIM, do so based on your ESP’s recommendations.
  5. Now copy the generated DKIM record and the DKIM selector your ESP should have provided.

Now, it’s usually time to enable DKIM for your ESP.

Return to your ESP's DKIM settings and look for an enable button. Click on it.
