Hello cooloolacarpet,

It's nice to have you here in the Community.

You can change your email from your company settings. Let me guide you how.

1. Go to the Gear icon at the top right of your screen.
2. Select Account and Settings.
3. Edit your email address under Contact info section.
4. Tick Save and Done.

I've attached some screenshots for you.

Once you change your business's email address, you customers will also see this info and how your business gets communications with Intuit.

In case you want to know what other emails you can change, please refer to this link for details: Change your email, user ID, or password for QuickBooks Online.

Please reach out to me anytime if you have other questions. Cheers!
