Ask HN: How do you track individually targeted emails?

Have you looked at Mailgun? (YC alum, now Rackspace)

(disclaimer: I did a guest blog post for them, but that was a result of me being a happy customer before they even contacted me)

They have lists, webhooks/reporting for tracking opens and clicks, HTML support, unsub notifications, etc. All accessible via the API. Poke around the docs and trial, sounds like it could be what you're looking for.

Seems like Toutapp ( http://toutapp.com ) solves your problem! :)

Thanks! Toutapp seems to be the only significant player in the space which seems odd given their $30/month charge.

Have you looked at ClickMeter? I wonder if this kind of functionality is harder to find because it may be harder to monetize.

ClickMeter is a start, but it requires adding the link into your email yourself which is a friction point for non-tech people.
