Review for Send Later by Shaun of the Dead
Rated 5 out of 5 stars
This plugin (and, to a lesser extent, 'Show All Body Parts') has become an almost essential part of my Thunderbird use and of managing my flow of information to clients. I love how easy and how intuitively it fits into my email workflow; It's clear that solid thought and time went into its integration.
I recommend it 100% to any other Thunderbird user.
