How can I find previous emails I have sent to a customer via quickbooks?

Welcome to the QuickBooks Community, Sarah!

QuickBooks does not have an outbox feature to store sent emails. It is not designed to function as a full-fledged email service platform. Therefore, users should be aware that QuickBooks does not provide the same email management capabilities as dedicated email services. If you need to manage your emails, it's recommended to use a separate email client or service alongside QuickBooks for comprehensive email functionality.
