  • How does EmailJS work?

    EmailJS helps sending emails using client side technologies only. No server is required – just connect EmailJS to one of the supported email services, create an email template, and use our Javascript library to trigger an email.

    Email templates can optionally contain dynamic variables in almost any field (e.g. subject, content, TO address, FROM name, etc’) which are populated from the Javascript call. For example, the subject can be “{{name}}, you have a new message”, and using Javascript the name can be set to “James Dean”, for instance.

    Additionally, you can easily add attachments, require CAPTCHA validation, switch between the email services without making code changes, review the history of the email request, and more.
