Hi Zoho Users,

I need your help about this simple problem i have.

 I want to create an e-mail template to send an answer to all my candidates in one time, with mass mail application. I tried this draft above (which is first draft when you open this application in "e-mail to candidate" tab)
but it doesn't work. Maybe it is because my html knowledge is terrible but i need help about this. When i send this template it doesn't content zoho id from my candidate list, just first name and last name can be seen from receiver. candidate id stays as html source code. Thanks for helping

Best Regards,
