Multiple duplicate emails received when sending invoice or estimate

Thanks for reaching out to the Community, jgerrish.
 

Since you appear to be receiving duplicate emails when you send invoices or estimates, I'd recommend initially checking your browser. It's possible this could have something to do with temporary internet files. Browsing applications store these types of records, but sometimes they can cause issues with certain webpages. You can open a private window and check to see if you're still seeing duplicate emails.
 

Here's how to access incognito mode in some of the most commonly used web browsers:

• Google Chrome: Ctrl + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Microsoft Edge: Ctrl + Shift + P
• Safari: Command + Option + P

If you're not seeing duplicate emails while browsing privately, it's safe to say this problem's being caused by the browser. It can be fixed by clearing cached data and Intuit-specific cookies.
 

In the event it continues occurring while you're browsing in incognito mode, you'll initially want to try switching to another browsing application.
 

Here's a list of supported browsers:

• Google Chrome - version 78 or newer
• Mozilla Firefox - version 76 or newer
• Microsoft Edge - version 75 or newer
• Opera - version 68 or newer
• Samsung - version 10 or newer
• Safari - version 12 or newer

You can also check a browser's compatibility with QuickBooks by utilizing our browser health checkup tool. QuickBooks supports the current and two previous versions of browsers. If you find that you're using an unsupported version, make sure to update it to its latest release. Steps for doing so can be found on the particular company's website.
 

In the event you've found no problems that could be causing this with your browser, I'd recommend using a different device and/or internet connection. If it continues happening on other devices and/or internet connections, you'll want to get in touch with our Customer Care team. They'll be able to pull up the account in a secure environment, conduct further research, and create an investigation ticket if necessary.
 

They can be reached while you're signed in.
