By default, when an email is sent from your iPhone, a “Sent from my iPhone” signature will be added to your message.
To edit this follow these easy steps:
- From your iPhone home screen go to the Settings menu.
- Tap on Mail.
- Select Signature.
There, modify the signature for all mail accounts you have set up, or on a per-account-basis. If you wish to have no signature, delete the entire text.
When ready, tap Mail on the upper left corner to save your changes.
