Klaviyo DKIM Setup 

DKIM (DomainKeys Identified Mail) is an email authentication method that uses cryptographic signatures to ensure emails haven’t been altered in transit and that they truly originate from your domain.

This article outlines the steps required to configure DKIM for Klaviyo, ensuring your marketing emails are authenticated and improving your deliverability and brand trust.

How to Configure DKIM and Domain Authentication for Klaviyo

To begin, you need to generate DNS records in Klaviyo. Klaviyo requires either 3 CNAME or NS records for email authentication, plus one TXT record for domain ownership verification.

Note: While all users can access the setup process, only those with Owner, Admin, Manager, or Campaign Coordinator privileges can make DNS changes.

Step-by-Step Instructions:

  1. Click your company name in the bottom-left corner of your Klaviyo account.
  2. Navigate to Settings > Email > Domains.Klaviyo Dkim Screenshot 1
