long URL isn't active from mail

Hi,

I want to send forms to end users, using a link sent via mail.

the link contains data that should be uploaded to the form with info relevant to specific users.

I created the URL to the form successfully, but when I send the mail, the user receives it as a text and not hyperlink.

the link to the form is very long, so I suspect that this is the reason it doesn't become active.

Any Ideas on how to approach this issue?

Thanks

Nitai
