Email templates in Zoho CRM should be global not module specific
The way you have the email template setup, you have to choose Leads, Contacts, etc. and then that email template can only be used on that module. You should have the ability to create a template that can be used from anywhere in the CRM. I find myself making tons of duplicate templates because one I use for Contacts I might also use for Potentials etc. This is totally unnecessary.
