The advent of email tracking has caused quite a bit of ruckus, and is generally, rather creepy. A NY-based startup called One More Company made an attempt to tackle this head-on with a service called Trackbuster, but now they’re interested in something else: “enhancing emails” by adding relevant and contextual info.
It is slightly intrusive at first, but in usage with Gmail it’s not without benefits.
Senders says that using Google OAuth and not sourcing public personal info (Instagram, Facebook) keeps the service safe.
Called Senders, the email service creates a sort of contact card within emails, including social networks, a short bio, photo, company address and other relevant info. Thus, performing searches on the person(s) within your emails can be easier, if not rendered moot, since Senders will fetch and catalog most of the publicly available information for you — all within the email correspondence.
An example of Senders working on the first try, with my own corporate email address can be seen below:

For those concerned about the information that would become too easily (or readily) available within the card, there is a way to stay somewhat elusive: a user can edit the information that Senders will pull being a registered user, by accessing a verification email and making edits to their public card. In my case, I added additional info while also making corrections, but the reverse can be done where my details within the card are whittled down.
Senders is currently in beta but is accepting sign-ups now, so that potential users can see whether or not it is useful for day-to-day emailing and networking.
Since information is filtered and not thoroughly intrusive upon the sender, it’s more likely relevant, if not exact information would appear.
For example, the first scan of my email rendered the TechCrunch Twitter account (seen above), and not my personal account (unless I made the configuration), so Senders can be thoughtful when it comes to portraying the most relevant info (and not overtly) version of the sender.
