What is Transactional Email?


A Transactional Email is one which is sent to a specific user in response to an action taken by the user. Although it is often related to a transaction such as an online order, it can also be related to other user actions such as registration on a company's portal, download of a whitepaper from a website, providing feedback using a web form etc. The products and technologies under this category provide a service or an API that can be integrated within an application to enable you to reliably send transactional emails.
