That brief period of time before the re-direct allow MKTO to track that the email was clicked by the user. |
Nope, the Click Email is logged regardless of whether the redirect finishes. The mere act of reaching the branding domain logs the click. That's why it will work even without JS support (though the person will never get to the real page).
But, if it is unable to log the webpage visit after something like .3 milliseconds, the request times out and the "visits webpage" activity will be lost forever. |
That isn't so. Visit Web Page logging doesn't time out after 350ms (you're thinking of Click Link on Web Page, which uses a synchronous call to let logging complete before loading a new page/asset).
Visit Web Page logging is lost when somebody navigates away from the page before the Munchkin request (not response) completes. If
(a) you load a ton of scripts asynchronously, so Munchkin doesn't start until late in the game
(b) the Munchkin servers are severely overloaded at a point in time
(c) you automatically redirect people away from a page using JS
(d) a user manually navigates away extremely quickly or closes a tab
or a combination of the above, you can lose analytics data.
However, in this case I'd be inclined to believe Munchkin is not running on the destination domain until proven otherwise.
