I´m having this problem to set up my DNs.
First! I set my shopify store with its records A and CNAME (so my domain is hosted in shopify) so far my site is working.
Second! I have a mail hosting from another provider which a need to set up Dns, so I´m not sure if I did it right because I still have problems with it and can set my email accounts on outloook and their not working because it´s not pointing to the mail server. Please if anyone can help me and give clue to solve it.
