A method and system for attaching a scan to an email reply utilizing a mobile communications device and any standard email client. A scan-to-email attachment module can be configured in association with the mobile communications device. A contact address can be added to a list of email contacts available via the mobile communications device. The contact address can be added by the user to a reply-to email as an additional address utilizing the mobile communications device so that a scan document can be sent as an attachment to an email address listed in the reply-to email. A server monitoring the contact address can be polled by the scan-to-email attachment module and a scan request initiated with respect to a scanner.

A fresh email can also be composed and the contact address can be added so that the email containing the scan document can be sent to the recipients.
