What Is a Transactional Email Service?<\/h2>\n\n\n\n

A transactional email service is a platform that sends automated, one-to-one emails triggered by a user\u2019s action, such as signing up, resetting a password or placing an order. Your app sends each message through the provider\u2019s email API or SMTP relay, and the provider handles authentication, delivery, bounces and tracking.<\/p>\n\n\n\n
