Can I find the emails sent to customers?

Yes, you can, @info-essltd-co-k.

You can utilize your Audit log and see the email you've sent to your customer. It shows your account activity for keeping track of your business. I'd be delighted to show you how.

Here's how:

1. Navigate to the Gear icon in your QuickBooks Online (QBO).
2. Select the Audit Log and click Filter.
3. Use the fields on the Filter panel to customize your search.
4. Then click Apply.

You can also read through this article that teaches you more about the use of an Audit log: Use the audit log in QuickBooks Online.

Furthermore, I've also added this resource that can guide you in personalizing your customer's invoice: Customize invoices, estimates, and sales receipts in QuickBooks Online.

In case you have any other questions about your customer's emails or your QBO account, simply add them to your reply. I'm always here ready to assist you anytime. Have a good one!
