Enable signature in mail account

[rackspacesupport]

I am using my Gmail account and also it has 2 other ([link removed] and Zoho mail) email accounts which are used to send and receive mails from the Gmail. So, I want to create separate signature for all accounts. Please help me.

Signatures tend to be a feature of the email app.
Some apps will tie a signature to an email account; some apps use only one signature for all accounts.
Which email app are you using?
