Using Google fonts for email signature

Question

I am using outlook as the email client. Due to some font problems, I have decided to use google fonts in the signature, so my expectation is whenever I send an email, and the font link is available in the signature, the receiver email client will automatically download the font from Google Server and display them. In the signature options, I have selected that the signature displayed should be of the type HTML, but I don't know how to specify that the font should be from google fonts. Can I somehow import google fonts in @Font-face? I am posting some code of my signtuare, kindly have a look. Thank you.

Signature :

<style>
<!--
 /* Font Definitions */
 @font-face
    {font-family:"Cambria Math";
    panose-1:2 4 5 3 5 4 6 3 2 4;
    mso-font-charset:1;
    mso-generic-font-family:roman;
    mso-font-format:other;
    mso-font-pitch:variable;
    mso-font-signature:0 0 0 0 0 0;}

<p class=MsoNormal><span style='mso-bookmark:_MailAutoSig'></span><a

lang=EN-US style='font-size:8.0pt;mso-ascii-font-family:Calibri;mso-hansi-font-family:

Google Fonts arent web-safe fonts. You should never use non web-safe fonts in an email signature. Web-safe fonts are basically fonts which are installed on most devices worldwide. If you use a font which isn't web-safe and don't specify a fallback font, you run the risk of the whole text not being visible on the device that you're sending the email to.
