How to Customize Your Email Signature on iPhone

By default, when you use the Mail app to send an email on your iPhone, your phone will automatically add “Sent from my iPhone” at the end of your message. If this default send-off feels too unprofessional or impersonal, you can change it into a custom signature with just a few simple steps.

First, open the Settings app on your iPhone and scroll down until you see Mail. Once you tap on the Mail option, scroll down again until you see a group of settings labeled Composing. Near the end of the Composing section, there will be a button labeled Signature. After selecting Signature, you’ll be able to delete the default “Sent from my iPhone” and replace it with something a little more you.
