On a web page mailto links open the default e-mail client. Now that Chrome offers the ability to set Gmail as the default e-mail client, some users have the links open in the same window thus taking them away from the page they clicked the link (which they do not like)
I have tried adding target _blank to the links, which works great for gmail users, but will drive Outlook users mad, because a new blank tab will open every time they click a mailto link.
I there a way to detect the default e-mail handler and offer a good experience for both types of users?
