You can make your email address in your signature a smart link that will automatically open a new compose email window when clicked:

  1. Highlight your email address text in the WiseStamp editor.
  2. Click the 'Add Link' icon. In the "Link URL" field add 'mailto:' and your email address
    e.g. mailto:YourEmail@gmail.com

 
Want to make your phone number an active link? Do the same but use 'callto:' instead:
e.g. callto:4151234876
