Log in to your @k12.hi.us email, click on the gear, then press Settings

Under General Settings, scroll down until you see: Signature

1. Select the account to add a signature to, be sure that it is your alias version ([email protected])
2. Type your signature, it is usually best practice to add a couple of spaces in the beginning so that it adds to your email nicely.
3. Checkmark: Insert this signature before quoted text. If you are responding to an email thread, checking this setting will put your signature under your reply, not at the end of the long email.

Scroll down to the bottom of the settings page and press: Save Changes
