How To Articles

Enabling DKIM in MailerLite is an essential measure for enhancing email delivery and avoiding your emails being flagged as junk. As a long-time user of MailerLite, I recognize the significance of this functionality and how it can boost your email marketing efforts. This article will walk you through the steps of activating DKIM in MailerLite, complete with thorough instructions and my personal insights.

What is DKIM?

DKIM stands for DomainKeys Identified Mail, which is an email authentication method that helps verify the authenticity of the sender and ensures that the email hasn’t been tampered with during transit. When you activate DKIM in MailerLite, it adds a digital signature to your outgoing emails, making them more credible and trustworthy in the eyes of email service providers and recipients.

Step 1: Generate a DKIM Key Pair

The first step to activating DKIM in MailerLite is to generate a DKIM key pair. This key pair consists of a private key, which is kept securely on MailerLite’s servers, and a public key, which is added to your DNS records. To generate the key pair, follow these steps:

  1. Login to your MailerLite account.
  2. Click on your account name in the top-right corner and select “Integrations” from the dropdown menu.
  3. In the “Integrations” page, click on “Domain authentication” in the left sidebar.
  4. Under “DKIM”, click on the “Generate” button.

Once you click on the “Generate” button, MailerLite will automatically create a DKIM key pair for you. The public key will be displayed on the page, and you will need to add it to your DNS records in the next step.

Step 2: Add DKIM Record to Your DNS

Now that you have generated the DKIM key pair, you need to add the DKIM record to your DNS. This step helps validate your emails and confirms that they are indeed sent from your domain. To add the DKIM record to your DNS, follow these steps:

  1. Copy the DKIM record provided by MailerLite.
  2. Access your DNS management panel provided by your domain registrar.
  3. Create a new TXT record with the name “default._domainkey” and paste the DKIM record as the value.
  4. Save the changes to update your DNS records.

It’s important to note that DNS propagation may take some time, usually up to 24 hours. Once the DKIM record has propagated, you can proceed to the final step.

Step 3: Enable DKIM in MailerLite

After adding the DKIM record to your DNS, it’s time to enable DKIM in your MailerLite account. Follow these steps to complete the process:

  1. Return to the “Domain authentication” page in your MailerLite account.
  2. Under “DKIM”, click on the toggle switch to enable DKIM.
  3. MailerLite will verify the DKIM record by checking your DNS settings.
  4. Once the verification is successful, DKIM will be activated for your account.

Congratulations! You have successfully activated DKIM in MailerLite. Your emails will now have a digital signature that improves their deliverability and credibility.
