How do I change the email address from which invoices are sent to my customers/clients?

To change/update the sender email address:

• Navigate to Settings > Email Notifications and click Sender Email Preferences.
• Click + New Sender in the top right corner of the page.
• In the Add Additional Contact pop-up, enter the name and email address of the new contact. You can also select a user’s email address from the dropdown.
• Click Save.

Now, this email address will be added as a sender in your organization. To send transactions using this email address by default, hover over it and click Mark as Primary Contact.
