Cant send invoices got this message on screen "Email hasn’t been sent. Double check your info and try again"

Hello, @apedro092.

I've got some steps to help you send your invoices in QuickBooks Self-employed (QBSE).

The error usually happens when the email address format is incorrect. To fix this, we can re-enter both your email address and your customer's email address on the Invoice page.

Here’s how to re-enter your email address:

1. Go to Invoices from the left menu.
2. Click Create invoice. 
3. Hit Edit work info. 
4. In the Email field, re-enter the email address.
5. Click Save. 

Now, let’s re-enter your customer's email address on the same page:

1. Click the Edit customer info.
2. In the Email field, re-enter the email address.
3. Click Save. 

Moreover, if the troubleshooting steps above do not work, you can resend the invoice using a new incognito or other supported browser.
