Do I need an email server if I use Jotform?

Can I disable my email server if I use jotforms on my websites?

I believe you do not need an email server. You can use our own default emails as the sender email for the notifications or autoresponders. Here are the guides on how to setup your email notifications and autoresponders:

If you wish to embed your form on a website, you can easily do that by using the embed codes. Here's a guide that you can follow: http://www.jotform.com/help/34-Adding-a-Form-to-a-Web-Page. There are also other platforms where you can share your forms.

Do let us know if you need further help on this.
