links may appear as plain text even if HTML format is specified - I suspect that email services like GMAIL.COM may misinterpret HTML if they do not find hypertext address start marks such as http:// or / in the link

in my case this happens and in order to notice it I had to look at the code of the page that the mailbox service generates

helper.setText(' a href='http://localhost:8086/'+appUser.getEmail()+'/' God /a ', true);

so I have to prove to Google that localhost:8086 is a link because it doesn’t believe the tag a href=localhost:8086/

I would be interested to hear professionals explain my discovery
