My customers don't recognize the Intuit email address. How can I have 2 options of e-mail addresses and select the relevant e-mail address accordingly in QBO?

Hello there, avd92 .
 

I'll share some insights about managing company's email address in QuickBooks Online.
Currently the feature to select two emails when sending forms in QBO is unavailable.
 

As a workaround, you can only modify your email address by these steps below:
 

Go to Gear icon.
Select Account and settings.
On the left panel, click Company.
Edit Company email and Customer-facing email.
Click Save.
 

Furthermore, you can check this article if you'd like to change your company settings and modify the features: Edit company settings in QuickBooks Online.
