Java language

The Java language, not to be confused with JavaScript, is a scripting language used to send emails via Simple Mail Transfer Protocol (SMTP) or an email Application Programming Interface (API). While web developers rely on JavaScript in web development, we don’t recommend using JavaScript in email development.

Java is a class-based, object-oriented language primarily used for coding web applications. Brands use it to set up webhooks to work with their web applications or interface with email service providers (ESPs).
