Need a little help here. First of all, Im using email forwarding. I use firstname.lastname@example.org and it is forwarded to my email@example.com email. When I email customer from shopify order page, the email goes out. However, when customer tried to reply to that email sent out by my shop, they will get email error. Therefor, Im not getting response back from customers. How can I fix this? It's kind of an emergency, if anyone knows how to fix this for me, please contact me. I can pay small fee thru paypal. Thank you.
