I don't have a website. Can I copy the source code into an email or facebook event evite?

I have tried to cosy and paste my form into my email and facebook and it isn't working. 

It is never a good idea to embed a form directly onto an email message.  Here's an article that tells us why.

You can instead include the direct link to your form on your email messages or facebook event pages. To get your form''s link, simply click Embed Form then copy the form URL.

You may also customize the latter part of the URL if you wish.
