Can I change or remove the email address at the bottom of the emails?

You can change the email address your customers see in the confirmation emails in the General settings of your Emails section. Please note that Return Magic notifications will also be sent to that address. We do not currently support to have multiple addresses, but you can create a team email as to reach everyone that needs to receive those emails.
There, you will also be able to choose to not make this email address visible to your customers.
