How do I add a Skype button, icon, link in my email signature
Adding a Skype button, icon or link to direct customers or clients to your Skype profile or business page in your HTML email signature is easy with Email Signature Rescue.
Just choose your Skype colored icon to match your business branding, add your link into the text box and away you go.
Skype buttons not supported in some email clients
Skype click to call buttons are not supported in all email clients (like Gmail). To overcome this, you can build a simple "http://" link that leads to your Skype link instead. This http:// link will work great in any email software, even Gmail. You need to do the following:
Go to http://is.gd/
Shorten your link skype:divparty?add and get the short http:// link
use this http:// link in email signature
profit! :)
Note: This will not work with other URL shortener services like Bit.ly. Only use the one provided above.
Big thank you to this StackOverflow article here and StackOverflow member @vanger for the tip!
