How do I know if my email was sent?On Street Invoice version 1.7 and higher:
The invoice will display a small green envelope icon on the expanded invoice list view.
Note: The icon will disappear if the invoice was edited.
You can have Street Invoice send a copy of your emails to yourself, so you'll know when your customer received their email. See this Help Center article details:
If Street Invoice is unable to deliver your email, you will receive a notice from firstname.lastname@example.org & if you are using Street Invoice version 1.4 for Android or later, you'll also receive a notification on your mobile device.
