11 incredibly useful things you didn’t know your iPhone can do

Why not change your signature?

Do as I don’t and change the signature file. (The phrase automatically added to every email you send) from the default "Sent from my iPhone" to something useful, such as your business name and contact details.

• Open Settings>Mail>Signature.
• Choose whether you want to use the same signature for All Accounts or Per Account for emails sent from your device.
• You then create a relevant signature.
