How to change sender email for domain purchased from third party site

Topic summary

A Shopify store owner purchased their domain from Namecheap and is experiencing an issue with email sender addresses. Currently, automated store emails are being sent from a generic Shopify address (store+[numbers]@shopifyemail.com) rather than a custom domain email.

The Issue:

  • Default Shopify email format is displaying instead of a branded sender address
  • Domain is registered through a third-party provider (Namecheap), not directly through Shopify

Status:
The question remains unanswered. The user has included a screenshot (help.png) that likely shows the current email configuration or the problem they’re encountering. A solution would typically involve configuring custom email settings in Shopify and potentially setting up proper DNS records or email forwarding through Namecheap.
