Is there a way to access the email on which an invoice was sent. I have a customer who said they haven't received it and want the original email details

I'd like to impart some insights about handling sent invoices in QuickBooks Online, @wesley-weldon-in.

The option to retrieve the original email sent to you after issuing the invoice is currently unavailable in QuickBooks. As a workaround, I suggest going to the Account and settings and selecting the "Email me a copy" option. This way, you'll get a personal copy everytime you send an invoice.

Let me show you how to do it:

1. Click on the Gear icon.
2. Go to Account and settings.
3. Select the Sales tab and scroll down.
4. Under Messages, put a checkmark on the Email me a copy at donotreply@intuit.com.
5. Once ready, click Done.

Additionally, you can also submit feedback about having this feature available in QuickBooks. Our product engineers will work on adding it in no time.
