An utility programming interface (API) permits two software program purposes to work together with each other by way of well-defined protocols and strategies. Inside the context of e mail, an e mail API permits purposes to work together with an e mail service.

Quite than opening an e mail consumer, composing an e mail, specifying a recipient and a topic, and clicking Ship, your software program utility can piece collectively the knowledge wanted for an outgoing e mail, then ship a request with that info to an e mail API. The API accepts this request and communicates it to the e-mail service, which subsequently sends the e-mail.
As talked about earlier, with an e mail API, you may programmatically deal with sending, receiving, and monitoring emails.
Let’s illustrate with a state of affairs. Suppose you’ve gotten a web based retailer and wish to ship a affirmation e mail to a buyer instantly after they make a purchase order.
