Email issues are notoriously difficult to resolve. Between IB and you, there are innumerable places where an email can be lost.

What we have been able to verify is that IB is sending out the email updates.

A small percentage of FTers are not getting their email subscription alerts. Unfortunately this only makes it more difficult to track down where, in the circuitous path between our email servers and your in-box, the emails are being lost. There's much more involved in this issue than configuring the FT email system correctly. It involves independently verifying that *your* system is configured correctly, plus that your provider is properly routing your FT mail -- and that's only 3 out of 1000 steps taken care of.

It's not ideal, but for the time being, I recommend MyFlyerTalk.
