In order to add an email signature to the bottom of your emails, click on 'Settings' in the upper right-hand corner of any Pitchbox screen. Click 'Email Settings' if you are a user, or 'Account Settings' if you are an Admin. Find the email for which you wish to add a signature and click the 'Settings' button next to it, then 'Email Signature'.
Edit your signature accordingly and don’t forget to click 'Save'. Once your email signature is added, you will be able to add it to any template or outbound email by clicking the 'Add Signature' button on the Templates screen.
For replies, you can use the 'Add Signature' button to quickly pull the signature set for your email account. You also can use the Email Account Signature personalization field in replies as well as in your templates.
