I can share some insights about using QuickBooks Online, @bjbonnici.
Once you purchase a subscription, any updates are being sent directly to the Master admin user of the company. To check your QuickBooks emails, you can log into your email service provider's (ESP) website and go to the Inbox.
In case you want to identify which one the system is sending updates, I suggest visiting the Manage users section of your account. From there, you can also update the email information if you have the required access rights.
Here are the detailed steps:
- Open your QuickBooks account.
- Click the Gear icon in the upper-right corner.
- Below Your Company, select Manage Users.
