Hey @TopGate, “mail” is a subdomain usually used for your regular email communication purposes so you should not use that for your email marketing. Definitely switch it back to “send.”
Since Shopify is your DNS provider, this is an issue you’ll need to work out with them. However, there are a couple things we can still double check:
- With CNAME records, you must use the Static routing option in Klaviyo. Shopify doesn’t accept NS records which uses the Dynamic routing option. Please confirm you have selected Static routing within Klaviyo.
- Please show us all your record inputs on the Shopify side (block out your API key!!!) so we can match them character by character.
