All order emails sent to your customers are recorded on the customer's order so that you have an email trail on what has been sent to them regarding that order i.e. confirmation email, pay by link email, reminder email etc.
To view these order emails, simply find the Order and open, then select the 'Messages' Tab. You'll be able to see the email heading and you can click this to see the exact email sent to the customer.
From here you can also resend the confirmation email (All Confirmation emails contain a link to the Intake Form)
Here is a guide on What emails will guests receive? This includes some orders emails that will appear in the Messages tab when sent.
