Case Email

Case Email

We want to send a case closure email by using email template, but we cant see any send email button in cases detail. i mean how to use case email template .. and how to send emails for cases.. for case created, closed etc.

Email template do have case columns, but from where could we send the email for a particular case, I am not able to figure out.

Zoho cant have this basic error. there should be a solultion for it.
