What am I looking at? There is zero information at that link. There's the contextless, meaningless text "all data in one place," a incomprehensible screenshot of a Google page with all text marked out, text asking me to sign up despite no sign-up link being present, and finally an offsite link to a Chrome plugin.

The plugin page finally seems to have some actual information. Why didn't you link to that instead?

I like the popup that I get that asks me for an email so that I can be notified when this is released. It won't accept an email address. Finally went over to the Chrome store and got a lot more info, but I'm not sure I trust it enough to install it.

Why would I trust a random site to see my emails?

If you wanna build something similar, you can use clearbit.com for getting lots of data from just an email address.
