I need to update the email address where my BillPay confirmations are sent. They are being sent to my personal email address, which was originally used to set up.

I'll help you update your personal information, pflores-cruisefl.

To update the email where you received notifications from Bill Pay, this is now automatically synced to your company's email, where QuickBooks can notify you. You can consider changing it from the Contact Info section in QuickBooks Online (QBO).

Here's how:

1. Go to the Gear icon and select Accounts and Settings.
2. From there, click Company.
3. Then, go to the Contact Info and modify your company email.
4. Click Save and Done.

Moreover, check out this article to learn more about how Bill Pay works for QBO: Learn about QuickBooks Bill Pay for QuickBooks Online.

If you're using QuickBooks Payments, your account info is updated in QuickBooks Bill Pay from your Payments profile. If you need to update your account info, check out this handy resource: How to update your info in the Merchant Service Center.

Stay in touch if you have any other questions or concerns about Bill Pay. I’ll be right here to answer them for you.

The first solution did not work, my info was already up to date in the main QBO settings.

The second solution, via the Merchant Service Center, did work! BUT with a little caveat. I had signed up for BillPay (to send ACH and checks to my vendors) but not Payments (to accept credit card from customers). I believe these services are linked but you do not get access to the Merchant Processing Center until you activate Payments, which I did just now.

If you need to change email for Bill Pay, you must activate Payments and visit the Merchant Service Center: http://merchantcenter.intuit.com/ 

Yes, I agree, pflores-cruisefl.
 
Thanks for following along the steps I've provided above.

You can change the Bill Pay email from the Merchant Service Center. Since you've already activated the Payments services, you're now able to modify the contact information from there.
 
Moreover, please know that you have different email addresses with your Payments account. Each one receives different kinds of messages.
