What it is

EmailJS is a lightweight library that allows developers to send text and HTML emails, including attachments, to any SMTP server. It simplifies the process of integrating email functionality into applications without requiring complex setup or configuration.

EmailJS stands out as a simple, open-source library that developers can easily integrate into their projects to handle SMTP-based email sending without the need for extensive setup.
