# Email Signature
An email signature is a personalized block of text automatically appended at the bottom of an email message. The Supervisor can create a signature email for each email channel in the **Customer Service** menu > **Email Template**. By default, each email channel only has one email signature. In 3Dolphins, it is possible to make signatures in text and image formats. In the upper right corner, click the '**signature'** button.
Select an email channel and click the 'edit' button ( 
), then you will see a form to create an email signature. For example, we create the signature of team product 3Dolphins as shown images below.
When you make an outbound email or reply to a customer’s email, the message will automatically be accompanied by an email signature. For example, go to **Customer Service** menu > **Customer Support** > click the **'Make Email Outbound'** button. On the outbound email form, the email signature will automatically be used as shown below
