Multiple e-mail signatures, a feature that should have been in iOS from day one, has finally been added to the operating system with the iOS 6 update.
Before iOS 6, users would have to set one generic signature and then add any extra information as they were sending the e-mail. Not anymore.
- To set up your e-mail signatures, launch the Settings app and then select Mail, Contacts, Calendars.
- Scroll down until you find the Signature option and tap on it.
- You'll be presented with the option to set one e-mail address for all accounts, or to set a signature per account.
The latter will let you to customize the signature for each account, allowing you to set a signature for your personal e-mail account and another for your work account.
Now, when you send an e-mail, iOS will automatically apply the proper signature based on the account you're using to send the e-mail.
