We have over 1800 email addresses loaded into the Trumba Address book, and 4 of them are showing the double red !! suggesting Trumba has had a problem sending these people email. All 4 addresses are valid. Aside from the fact that maybe these people inadvertently added the Trumba to a junk email list, I'm curious if someone there might have some additional input as to why these 4 are showing up like this. I deleted them, and re-added them to find the same thing.
