How do they determine engagement time or whether the email was deleted?

I have no idea (didn't find out from a quick browse through the site), but the first thing that came to mind was an image in the mail, pointing to a server that slowly trickles a response without ever finishing so it can measure how long the other end is listening.

We have a special tracking code that figures it out over the email clients' use of HTTP and with some fancy server-side node/mongodb stuff.

Bullshit. There's not a single major client that executes code from emails.

You might be able to have some link back to your server, but even those are blocked by default.

Pretty genius idea but easy to replicate by the big boys..
