Sendmail without attachment question

Hello,

I've ported my license manager application written in Java with the Zoho Creator within minutes (just to try it out and have fun! It's GREAT!).

Sadly it's not possible to send attachments, so it's rather useless for me, because when I enter a new customer a small file with
the license key is generated and attached to the email (at least in my java version).

The only other solution I see instead of an attachment is:

After creation of the customer entry create a file in some zoho webspace where the user can download it from (by automatically adding the link to the email).

Is something like this possible or do I still have to use my Java app?

Best regards,
Michael
