I am testing the stripe payment in development mode and the receipt is not emailed. Its also creating new customers in stripe dashboard for every transaction.
As a note, we’ll only send email receipts for payments that are made with your live API key or through your live dashboard. If you’d like to see what a test email receipt looks like, you can click the “View Receipt” link on a live or test payment’s page. You can also send a test email from your email settings.
