To change the email address that all system generated emails will be sent from, go to > Business Details and scroll down to the System Email Addresses section.
To change the email address on only specific templates, go to Email Templates under the </> icon.
Here you will find a list of folders that contain all the system generated emails. You can edit each email by drilling into the related folder and editing the “from” field or "to" field. Enter the email address you want emails to be sent from or to here. You can add additional email addresses by comma separating them. These fields work much the same way as the from and to fields in your everyday email client.
Click on the section and then the template.
You can change the From, To and BCC fields and save the changes.
