Hey Shopify Community!
I recently lauched our site and wanted to share my solution to the headache I created when connecting my existing domain to Shopify. This meant for everyone not comfortable with DNS settings and how to manage connecting the domain to Shopify while keeping your emails hosted on the 3rd party server (I’m no expert - but I just spent my entire Saturday learning about them).
Shopify’s instructions to connect your domain are nice easy and straightforward - here https://help.shopify.com/en/manual/domains/add-a-domain/using-existing-domains.
What if you have your email hosted on the same web hosting that provides your domain registration? This is where my headache started. Website DNS A record and CNAME switched to Shopify - perfect. And then my entire company stopped receiving emails… ouch!
This was because of how the mail server and other DNS settings in my web hosting were configured originally. They referred to one another - why? Because that is a nice simple setup when website, email and domain are all held in the same spot.
My advice when connecting your domain to Shopify, to maintain uninterrupted email service - make sure that the MX record refers to your IP address not Shopify’s. Otherwise you will have emails floating in cyberspace looking for the wrong way home!
