The open tab is how all the other email signature

The open tab is how all the other email signature icons work, basically they are an image connected with a link to the person's page on linkedin or whatever. When you click the image it take you to the personal page of that person in another tab. So this will feel exactly the same as that to everyone, except you get the notifiID video, which imo is much much better at giving a feel for the actual person.
