Frequently Asked Questions
Can I use EmailJS for free?
You can send up to 200 emails per month completely for free. If you need to send more emails, want to use advanced features like file attachments or remove our footer from the emails – please take a look at our plans.
Can’t I use services like Sendgrid or Mandrill directly?
All email services require some sort of authentication to send the emails on your behalf. That makes it a really bad idea to use them directly from client side – revealing your password or your secret keys will allow anyone send emails on your behalf.
EmailJS keeps your authentication details on the server side, and the client side code just triggers a predefined email template, similarly to how any client-server application is working.
Does EmailJS expose my account to spam?
Additionally, we’ve also developed various tools to prevent abuse – for instance, we have IP based rate limits to prevent bots from spamming, and also support CAPTCHA tests to make sure that a human is sending the email (although it’s up to the developer to turn this feature on).
Can I send HTML emails?
Absolutely! HTML emails are fully supported, and you can create them either using our visual text editor, or by entering the HTML code directly. That said, most email clients don’t fully support all the HTML and CSS features, so please refer to this Campaign Monitor guide to learn about the various restrictions.
