Transactional Email Software Overview
What is Transactional Email Software?
Transactional email software allows users to send one-to-one personalized emails based on trigger events that occur in the user's app or on their website. Examples of transactional emails would be a welcome letter, a shipping confirmation, or an e-receipt. At the heart of these products is an API used to configure and detect the trigger events. Often the email builder and analytics offered in transactional email tools are fairly basic.Some email marketing and marketing automation providers offer transactional email capabilities in addition to campaign-based functionality. There is also some overlap between transactional email tools and mobile marketing products that send transactional SMS messages, or transactional email messages triggered by activity within a mobile app (like a welcome email for new users sent upon creating an account in the app).
