Review for Send Later by pbosakov
Rated 5 out of 5 stars
This adds convenient outbox scheduling features, bringing Thunderbird up to par with other popular e-mail clients. I use it to delay emails to clients and partners in other time zones, I don't really want to bother them at night.
This review is for a previous version of the add-on (6.3.1).To create your own collections, you must have a Mozilla Add-ons account.
