API

An Application Programming Interface (API) is a programmatic way for applications to communicate with one another. An email API is a specific type of API that allows email developers to integrate their applications with email service providers (ESPs). This lets email developers send and receive emails and take advantage of ESPs’ email analytics and deliverability services from within their own environments.

Abandoned cart email

An abandoned cart email is a triggered (or transactional) email sent to customers when they leave a web shop without purchasing the items in their shopping cart. It acts as a friendly reminder to encourage potential customers to take action, converting them to buyers after they have navigated away from your site.
