What Is Transactional Email?

Transactional emails, also known as triggered emails, are automated emails sent after a particular action or transaction has been performed. Transactional messages tend to have high open rates because they often contain information that the recipient needs to read and are personalized. Experian found they receive “8x more opens and clicks than any other type of email and can generate 6x more revenue”. Transactional emails are sent through an SMTP relay or programmatically through APIs.
