'is there a way for links on yahoo spam folder to stay working?

I'm facing a problem on yahoo email. Once the email arrives at spam folder my links would be not clickable but images are. Inspecting the element found that the entire href attribute has been removed ! I found from the web that is related to the structure of the link. It says that link must begin with http:// or https:// and I tried it but still links are not clickable on spam. Any suggestions ? This is an example of my email body code :

these are ways i tried

example 01

<a href="http://www.google.com"  rel="noindex ,nofollow" style="text-decoration: none;" target="_blank"><h1>example 01<h1></a>
 


 

example 02

<h1><a href="http://www.google.com"  rel="noindex ,nofollow" style="text-decoration: none;" target="_blank">example 02</a></h1>
