What is Trans Email ??

Transactional emails are a crucial component of any business’s email infrastructure & communication strategy. When an email is sent to your subscriber or customer in response to an agreed-upon transaction between you and your subscriber or customer, it is referred to as ‘Transactional Email’. Since, transactional emails are triggered not by a business’s marketing campaign as is the case with marketing or bulk emails, but by specific interactions, events, customer/subscriber action or preferences within an application or service; they are also called ‘triggered emails’.
