HTML page as email content

HTML page as email content

I need to send an html page (based on my app's data) as an email content. (the html page itself works great)

I tried doing so as it says in this help page -  https://www.zoho.com/creator/help/script/send-mail.html
by copying all the html code from my zoho page, to the message content in the "deluge mode" (send mail task)

It doesn't work.

Anything I'm doing wrong here? Is there a limitation on the html code length when sending it as a mail?
Is there any other way of sending an html page as an email content?


Thanks!
