Unfortunately, BlunderDelay does not include a default "Send Later" button that works even when Mozilla Thunderbird is online. Editing scheduled emails could be easier, too, and a guaranteed time in the "Unsent" folder for editing would be nice.
- BlunderDelay delivers emails you send in Mozilla Thunderbird in in bulks at a predefined interval
- You can recall and edit messages that have been queued but not yet delivered
- BlunderDelay's interval can be set freely
- BlunderDelay does not warn you about unsent mail when you quite Mozilla Thunderbird
- No way to use the "Send Later" button while online (and by default) is included
- Editing scheduled but not yet delivered emails could be easier in BlunderDelay
- BlunderDelay periodically delivers messages sent using the "Send Later" command in Mozilla Thunderbird.
- You can specify the interval at which BlunderDelay delivers messages in bulk (hours, minutes or seconds).
- Messages in the "Unsent" folder and scheduled for BlunderDelay delivery can be edited or removed using "Message | Recall".
- BlunderDelay supports Mozilla Thunderbird 1.5/2.
Fortunately, BlunderDelay delivers my Mozilla Thunderbird emails only every three hours, giving me enough time to revisit, recall and rewrite.
Enough time? Unfortunately, BlunderDelay knows only one schedule and sticks to it. If you "send later" a message and BlunderDelay's regular delivery time comes a few seconds later, you have but these few seconds to reconsider. A way to set a minimum time for messages to reside in the "Unset" folder would be great.
Speaking of "sending later", it would be nice for BlunderDelay to include an option that made sending via its schedule mechanism the default. (You can use additional Mozilla Thunderbird add-ons — such as MagicSLR — to make Mozilla Thunderbird's "Send later" work while online.) "File | Send Later" always works, of course.
To change a message already scheduled but not yet delivered by BlunderDelay, you have to "recall" it using its context menu. Easy when you know what to do, a double-click, for example, would be more obvious.
All in all, BlunderDelay is a nice add-on that gets rid of immediate message delivery and typically offers you some time to rethink an email — even after you have sent it.
