Yes, we can add a second email address to a customer, tony.
QuickBooks Online (QBO) allows users to add multiple email addresses for a customer by entering them separately with a comma, enabling efficient communication with different contacts associated with the same customer.
No worries, this is quick and easy. Let me show you how:
Go to the Customers page.
Choose the customer's name, then hit Edit.
In the Email section, enter the email addresses separated by a comma (sample1@intuit.com, sample2@intuit.com).
Click Save.
