Personally I would really focus the ability to know when your email has been read, there are many analytics software providers that give you far more detailed statistics than your package will.

While I know there are email trackers and from a commercial point of view you would be using an email marketing provider.

But from a consumer's point of view tracking when a really important email has been sent could be a great idea. I would use it if I was sending an email to someone I hadn't contacted before but respected a lot and placed a high value on being in contact with them.

As a result if I was running the site, I would focus the branding and marketing on the consumer level, simple to use email tracking versus commercially focussed stuff.

Also tip: maybe don't use so much tech mumble on the homepage, tell the user about the results of your technology on the homepage and the details of the technology on a sub-page, otherwise you are just confused if you are coming from a search engine or social media site.

So something like: "copy and paste this one line into your emails and know whether the recipient has read your message".

Looks like a cool idea so keep going.
