CloseReview for ThunderPlunger by Charles Bragg
Rated 5 out of 5 stars
I really needed email verification because when sending a long list, Thunderbird would not tell me which address was causing the whole list to fail. TP saved me oodles of time. And, David was very helpful when I had a question. Kudos!
