This is also an effective way to get rid of the “Sent from my iPhone” text that is being added to your emails, as it is the default signature on any iPhone.
Step 1: Touch the Settings icon.
Step 2: Scroll down and touch the Mail, Contacts, Calendars option.
Step 3: Scroll down and touch the Signature option.
Step 4: You can select the All Accounts option at the top of the screen if you want this signature to apply to all of your accounts, or you can select the Per Account option and set a signature for each account.
Step 5: Touch inside the text field and delete any existing signature, then enter the company standard template and adjust your name and number for signature.
