Ever been stumped about emailing someone, unsure of how the person would respond? Crystal, a paid service, will trawl the Web to learn more about you and about your subject.
This service knows too much
Ominously, the site's registration form has this line: "Your company website allows us to give you free unlimited access to your coworker's profiles." It's a teaser of how the site works - by using the Web, Twitter, Gmail to find out data about you and your contacts.
What's a bit scary is that it will create profiles based on those personality test metrics you see a lot online and then will advise you just how to approach them. It might tell you to keep emails brief, suggest you insert more jokes if emailing a certain joke-loving person and scare you by creating a rather accurate profile of how you communicate.
Email templates are also an add-on feature with the service and even comment on how you get along with people.
If you would like to give the service a spin, get in line for a free trial at the company's website.
