Setting the contact e-mail for your e-shop is very easy.
Take a look at how to do it.
Where is the e-shop contact e-mail used?
The e-mail of your customer support is included in the payment status e-mails. This is an automatic e-mail informing the customer about the payment state. If for some reason the customer's payment fails, they will be able to contact you at that e-mail to ask for help.
Where do you set the e-mail?
1) Log in to your business account.
2) On the Settings tab, select the E-shops tab.
3) From the list of actions, select the Contact e-mail for customers settings option.
4) Enter the e-mail of your customer support or an e-mail at which the customer can contact you.
