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 Mail.
- Select Signature.
- 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 in the upper-left corner to save your changes.
