Google plus icon for email signature

Here are a few Google+ icon options you can use in your email signature:

1. Google+ Icon (Simple):

   <img src="https://ssl.gstatic.com/images/branding/product/1x/google_plus_48dp.png" alt="Google+" />

2. Google+ Icon (Colorful):

   <img src="https://ssl.gstatic.com/images/branding/product/1x/google_plus_color_48dp.png" alt="Google+" />

3. Google+ Icon (Circular):

   <img src="https://ssl.gstatic.com/images/branding/product/1x/google_plus_circular_48dp.png" alt="Google+" />

4. Google+ Icon (Icon Font): You can also use an icon font like Font Awesome to add the Google+ icon to your email signature. Here's an example:

   <i class="fa fa-google-plus" aria-hidden="true"></i>

   Make sure to include the Font Awesome CSS file in your email signature or add the icon font to your email client.

Remember to replace the alt attribute with your desired text, such as "Connect with me on Google+".

You can also use these icons in combination with other social media icons to create a comprehensive social media presence in your email signature.
