  • What is a Mailchimp transactional email?

    Mailchimp transactional email is a delivery API, or application programming interface, that can deliver transactional emails to customers without you overseeing the process.

    Transactional emails, also known as “triggered emails,” are one-to-one messages sent when a specific action occurs or a request is made from the contact. For example, a customer may receive a transactional email with their order information after a purchase is complete. Other examples of transactional emails include account updates, password reminders, and notifications or alerts.

    Compared to bulk marketing messages, transactional emails are only sent to one individual at a time rather than a group of people. Typically, these emails are time-sensitive and require you to deliver messages quickly. With our transactional email service, you can automatically send messages to the recipient’s email server in 1.79 seconds.

    When you send a transactional email with Mailchimp, you can ensure customers receive the information they need in a timely manner. Not only do transactional emails have the power to boost customer satisfaction, but they can also increase loyalty and engagement since they’re capable of being personalized. Remember, every interaction with a customer is an opportunity to solidify your relationship with them.
