Love it! A feature request: If I set up an e-mail to be sent regularly (daily/weekly/whatever), it would be nice to be able to give a stopping date.

Good idea!

I'll add it to my to-do list.

Awesome Add On Rated 5 out of 5 stars

Thank you, this add-on makes my life a lot easier. I work late at night and don't want my clients getting emails at 3 am so I use Send Later to deliver emails to them during the normal workday. Works great, no issues, love it!

I like the functionality. But I dislike the weird design of the dialogue window. Please make it possible to use colours and fonts/font sizes according to current system settings. I believe, the dialogue could be redisigned to look a lot simpler.

"Send Later," an essential e-mail business tool Rated 4 out of 5 stars

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 looked pretty good at first, but the interface of the schedule dialog could be much clearer. Instead of "send to outbox" and "send now", it should only have a "schedule for send" button. I clicked the "send now" thinking that would send it as a schedule message. An email just went out Friday night instead of Monday morning... Why have a true "send now" button when you wouldn't even use this addon's functionality when sending a regular, non-scheduled email?

Okay, that makes sense. Thanks!

Can't please everyone

I have tried various different layouts for the prompt window, and no matter what I do, somebody complains. At some point all that's left to do is to find the interface design that seems to provoke the fewest complaints, and do my best to document it for the few people who are still confused.

I'm not sure how to make it more obvious than it is now -- the "Put in Outbox" and "Send Now" buttons are in an entirely separate box in the dialog, outlined in red, and the button for scheduling a message is labeled "Send Later at time(s) specified above" -- without making the interface more clunky rather than less.

I understand that some people do not find the interface entirely intuitive. That is why there's a user guide as well as detailed, explanatory tooltips that pop up when you hover over the buttons.

The "Put in Outbox" and "Send Now" buttons are there because people use them. "Put in Outbox" is necessary because when Send Later is installed, that button is the only way to put a message into the Outbox. "Send Now" is necessary because some configure their "Send" button to _always_ pop up the Send Later dialog, and they need the option when the dialog pops up of sending the message now rather than scheduling it for later.

Amazing tool Rated 5 out of 5 stars

As a graphic designer I often find myself working really late at night, and nowadays with the help of the smartphones if you send an email at 3 am it's very likely that you wake up your client, also if you send emails at late hours you can send the wrong impression that you are free to work at whatever time they desire, so in order to protect myself and the rest and peace of my clients I started looking for a way to send my emails early in the morning while I'm trying to get 5 hrs of sleep, and I found this amazing add-on, I'm in love with it, just today it help me sent 6 emails at 8 am while I was getting my beauty sleep, xD, download it and try it, you won't regret it!!

Great product, very helpful Rated 5 out of 5 stars

I have been using this add on for several years and am very pleased with it's functionality and ease of use. It is a nice tool to use to send to people messages when they may get notification at odd hours or if you are up late and don't want to advertise that fact. I have donated to the program and would encourage you to also to keep it being updated and improved.

Very nice! Would be even nicer if I had the option to configure

-Send tomorrow morning at 9:00

With ONE button. I believe I would use it all the time
thanks!

See user guide

The user guide (http://blog.kamens.us/send-later/) shows how to set this up.

It does require some manual configuration, but I'm not sure how to avoid that. Everyone wants something slightly different from the add-on, and if I tried to make everything everybody requested point-and-click, the add-on would be too large, unwieldy, and difficult to use.

Very necessary Add-On Rated 5 out of 5 stars

I use Mozilla Thunderbird 24.5.0.
Function "Send Later" was necessary.
IMHO developers Mozilla Thunderbird
it is necessary to add this possibility.
By means of "Send Later 4.2.3" I have solved this problem.
All works perfectly. Five stars from me

is great, but CMD + SHIFT + RETURN (in Mac is command, not control), is hard to remember and not very usable... an icon on the message menu would be great.

Thanks and keep up the great work,

Great Rated 5 out of 5 stars

Thank you to the developer because this add-on is mandatory for my life. I routinely write messages at 2AM to be sent out during "normal business hours" later that day. I would need to stop using T-Bird if this extension were not available. Frankly I don't know what I would do because no other email client does what I need (Gmail isn't an option).

I haven't had any issues regarding "spamming" or multiple sends. I will update this review if I do. I only have SendLater check the drafts box every 10 or so minutes, however -- not every minute. I don't need to specify the exact time that emails need to be sent. Perhaps changing that default value might help?

I ran T-bird 2.0 for years, then two years ago switched to 3.1, and only a week ago switched to the latest version. I am wary of "upgrades" because my email system needs to be absolutely bomb-proof or I stand to lose a great deal of money. I used the Mail Tweaks "Defer" add-on for years which worked fine, but this seems to have more options and I'm looking forward to integrating it into my business and my life.

muy util y practico Rated 5 out of 5 stars

Es una de las extensiones que mas uso, me permite escribir mails en cualquier momento y enviarlos cuando comienza el horario laboral, permite configurar botones por minutos o simplemente ingresar un dia y hora especifico. Hace mas de 1 años que lo uso y jamas me ha fallado.

Nuff respect! This extension/add-on is exceptional. Works flawlessly so far. I can't send any $$$ unless you will take Jamaican dollars but if you ever come to Jamaica link me and I'll treat you to the best Jerk Pork and Chicken in the world! Thanks for the hard work it is sincerely appreciated.

bug Rated 5 out of 5 stars

hi,send later don't send "Disposition-Notification-To"and alsoReporting-MTA: dns


I mean that

in these case i ask for reporting ok

when send later is activate i don't have the "reporting mta"
when it is desactivate i have the message
like this :

Reporting-MTA: dns; .....................org
Arrival-Date: Mon, 17 Dec 2012 08:06:21 +0100
Original-Envelope-Id: <50CEC44F.2000801@.........................

Original-Recipient: .............@....................
Final-Recipient: rfc822;...........@.................
Action: relayed
Status: 2.0.0
Remote-MTA: smtp..............

i see nothing in the user guide about this.
a bug ?

This review is for a previous version of the add-on (4.1.5). 

See user guide

There is a workaround in the user guide at http://blog.kamens.us/send-later/#receipt for the Disposition-Notification-To issue.I'm afraid I don't understand what you mean when you say that the add-on does not support "Reporting-MTA: dns".

As far as I know, "Reporting-MTA" is a header inserted into bounces by mail transfer agents, not one that is meaningful when inserted into a message by a mail client like Thunderbird. Could you clarify?

UPDATE: Aha, I think I understand now. You mentioned "Reporting-MTA: dns" because it is what is inserted into the return receipts you get when you specify Disposition-Notification-To. In that case, my answer above still applies -- please use the workaround in the user guide if you want return receipts for messages sent with Send Later.

Nützlich, so lange TB auch zur Sendezeit an ist. ;-) Schön wäre eine Möglichkeit, als Sendezeit einzutragen: "Beim Schließen von TB".
