How to Fix DMARC Alignment for Klaviyo

Klaviyo DMARC alignment requires dedicated sending domain setup — adding CNAME records for DKIM and a custom Return-Path to enable full SPF and DKIM alignment.

Why alignment fails

Without a dedicated sending domain, Klaviyo cannot align bounces and DKIM with your brand domain. Use Klaviyo's DNS wizard for exact hostnames.

Exact DNS records

(From Klaviyo → Dedicated Sending Domain — copy exactly) DKIM CNAME(s) + Return-Path/bounce CNAME as shown SPF may include Klaviyo via TXT on root or subdomain per setup

Step-by-step fix

Step 1 Klaviyo → Settings → Email → Dedicated Sending Domain

Step 2 Klaviyo recommends a subdomain such as email.yourdomain.com

Step 3 Copy DKIM and Return-Path CNAME records from Klaviyo

Step 4 Add all records at your DNS host

Step 5 Wait for Klaviyo to verify — up to 48 hours
