I've been a daily user of the "Send Later" Add-On for Thunderbird for two or more years. At first I thought the primary advantage would be the ability to recall embarrassing messages pushed out with over aggressive use of the send button. Subsequently, I have found it is useful in other ways as well.

Often, soon after crafting an e-mail response to an inquiry, I find the sender has sent an update to that inquiry. By using "Send Later" as standard operating procedure, I'm able to cancel what has become an out-of-date response.

Finally, the "Send At" feature allows me to schedule the delivery of my e-mail message without the need to remind myself to send it out at a later date. The tool is useful when you want to deliver a message to a vacationing colleague, but you want to deliver it after he has gone through the stack of messages that piled up while he/she was away.

This review is for a previous version of the add-on (6.3).

Few e-mail messages are so urgent that they must be sent immediately. In contrast and often far too often, many e-mail messages are sent before they're error free. With "Send Later" add-on I regularly delay the sending of most of my messages by an hour, so I have an opportunity to grab it back and make corrections, should I later realize a mistake. Most of the time the messages go out without revision, but for those few times when I realize I've made a blunder, "send later" has saved me lots of embarrassment. "Send Later" is a tool that I use every day.

This review is for a previous version of the add-on (4.4).
