Hello @eisbell,

As of the moment, there isn't an integrated way to enter more than one email address to be used for email notifications in your Payments account.

With this, let's follow the steps and screenshots shared by my colleague, @ReyJohn_D, above to enter your email address. Once you receive the email notification, consider manually emailing the message to the other email address to whom you wish to receive the notification.

Additionally, I've also included this reference for a compilation of articles you can use while working with us: Help Articles for QuickBooks Payments.

If there's anything else that I can help you with, please let me know in the comments below. I'll be here to lend a hand.
