Since I connected my domain www.beneficlife.com to my shopify account my emails are not working

 I connected my domain www.beneficlife.com to my Shopify account, then my emails are not working anymore. 

I contacted godaddy support, they suggested me to edit the A record from 22.227.38.65 (Shopify) back to the godaddy server. but it disconnects my domain from Shopify. and now I added an extra A record. 

But my email still couldn't work. What can I do.
