If you already have Plesk hosting and would like to create an email signature for your email address, follow the steps below.

Step 1. 

Log in to your webmail by visiting webmail.yourdomain.tld (replace yourdomain and .tld with your actual domain name and extension).

You will be prompted to enter your username and password. Fill in the required fields, then click “Login.”

Step 2. 

In the left-hand menu, click "Settings", then "Identities."

Step 3. 

You will see your email written, and this is considered one identity. Click this.

Step 4. 

This will bring up a page where you can fill out all the information below, and add your signature at the bottom. Once you have provided the information, you will be able to "Save" the identity. You are able to create multiple and delete when needed, but using the two buttons at the top.
