Fantastic! (+small bug to fix) Rated 5 out of 5 stars

Thank you for this fantastic add-on! This functionality is extremely useful, and I've been looking for it for very long on Thunderbird!

I have noticed something I find a bit problematic. When you accidentally select a date and hour which are not in the future but in the past, the email is sent immediately. I think you should add a warning message pointing out that the user probably mispecified the date and time he wanted for the dispatch.

EDIT: Thanks for your quick reply!

Good idea!

That's a good idea. I'll add it to my to-do list to be implemented as time permits.

These are the add-ons that contribute to make a beter world. Rated 5 out of 5 stars

It just does what it says on the tin. A must have.
I use this add-on to send reminders for the deadlines: I just write the message when I set the deadline, and also the message with the reminder for 20 days later, and then i just forget about it.
Thank you!

Life Saver Rated 5 out of 5 stars

I use this add on every day. I work late at night and don't want my clients to see emails from me at 3 am, so I set them up to be sent around 7 am. It works and I love it!

The missing piece Rated 5 out of 5 stars

The only function I regularly used in Outlook and missed in Thunderbird was the possibility to specify a time and date when to send a message. An Add-On with the name "Send Later" was quickly found and installed.

Now that I tried it, I find the name "Send Later" to be a massive understatement of this app's capabilities. While it gives you the possibility to easily send emails at a later stage (and with a lot more comfort than Outlook's function at that!) , it allows you an immense level of customization.

You want to send every email with a delay of 15 minutes, in case you change your mind? No problem. You want to send your email on a specific time and date? No problem. You want to send your email immediately if it's business hours or else the next day? No problem. You want to send an email only when it's full moon? Well, not built-in, but with a bit of JavaScript you can do just about anything. :)

Really, great app. Thanks to the dev for making this available for free and open source.

Thank you!


A Simple But Very Useful Add-On Rated 5 out of 5 stars

The ability to schedule when an email will be sent is very convenient. I use it to remind myself or others of an upcoming event two days before. In my experience, an event reminder weeks before will soon be forgotten. I have to schedule events months ahead but already sending a reminder is useless as most will forget about the reminder and the event altogether. Yet, remind people two days before and the attendance is suddenly much higher. People still have full day to prepare or arrange things before the event and don't nag me for reminding them last minute.

So far, this add-on never failed me.. For reliability alone, this add-on deserves 5 stars!

Works great! I use it every day Rated 5 out of 5 stars

I often write up e-mails when the thought occurs to me. However, I don't always want to bother the recipient just because I thought of something. This allows me to send information to people when I want them to have it. It's useful every day!

Helps me with organization! Rated 5 out of 5 stars

I love this add-on because some weeks, I have a lot of time, and I can think ahead to reminder emails I need to send out to people. I just schedule it to send the next week (when I know I'll be busy and forget!) and it keeps our organization on track. I also use it to schedule to send birthday emails, so I don't forget when the actual birthday happens.

Very useful and complete Rated 5 out of 5 stars

This is a feature that Tbird lacks and many of people have a need for this. I don't use it often, but when I need it, I'm glad it's there.

Get SEND LATER Now Rated 5 out of 5 stars

If I only used it for preparing birthday emails and holiday emails in advance and scheduling their delivery I would be pleased. But the newest version offers an opportunity to set a default delay in sending ANY email I write. This is not a feature of Thunderbird so having a facility to give me a chance to stop an email a moment or two after sending it (I made my default 2 minutes, I'm pretty slow in the morning to rethink my actions) is priceless.

Excellent add-on Rated 5 out of 5 stars

Unmissable add-on for the send-button "trigger-happy" like myself ;)

Use it now, and send them later Rated 5 out of 5 stars

I am using this extension to send email "just on time", on work hour. Stop sending mails @3 AM... ("No, I was not spending my time playing WoW) I am sending them at 8:12, taking my cup of coffee :) "Oh yes, I am already working for you"
I recommend it !

Works well, easy to use Rated 5 out of 5 stars

now my coworkers wont know that I was up at 4am working. I like that I can move the toolbar next to the regular send button and set the time without having to go through another dialogue.

Send Now button is gone - need it back Rated 5 out of 5 stars

Love this add-on, but the latest update removed the Send Now button from the dialog. I have all of our users setup to ONLY have the Send Later dialog as their only option for sending email and this has everyone confused and unsure how to send a message immediately.

This is a 5-star add-on, and I'll change my review from 1-star as soon as I can resolve this issue.

EDITED: Thanks for explaining the issue and offering it as an option! Keep up the great work. Review changed back to 5 stars!

Back in release 5.2

EDITED: The information below is unfortunately incorrect. Please see the version notes for release 5.2.1 of the add-on for a complete explanation (it's really too long to explain here).

The release notes for version 5.1 say:

>>> In a further effort to reduce confusion about the “Put In Outbox” and “Send Now” buttons in the Send Later dialog, the “Put In Outbox” button is now only visible when the dialog is popped up using “File | Send Later” or Ctrl-Shift-Enter, and the “Send Now” button is now only visible when the “‘Send’ Does ‘Send Later'” preference is enabled and the dialog is popped up using “File | Send Now” or Ctrl-Enter.

Since release 5.1, I've heard from a number of people including you whose workflows depended on both buttons being present. This is yet another example of "no good deed goes unpunished" -- often when I make a change attempting to make the add-on work better for some people, I find out too late that it makes it work worse for others, and I unfortunately don't have enough beta testers to catch these situations before they go out to everyone.

Because of these workflows of which I was unaware, I just released version 5.2 with a preference you can enable if you want the "Send Now" and "Put in Outbox" buttons both to be displayed all the time. You'll get this release automatically when the editors approve it, or you can download and install it from , after which you can open the add-on preferences and check the box to bring the "Send Now" button back.

Great addin for Thunderbird, works great ! Rated 5 out of 5 stars

I have been using this little program for a number of years now and it enables me to send individual emails out to my customers rather than BCC copies or having our customers emails listed to everybody. Great little program, 10 out of 10!

Works well and usefull

stopped using it Rated 2 out of 5 stars

This is a very useful add-on, in principle. But, I had to stop using it because of its incompatibility with Enigmail. Apparently this is a known bug, and I'm waiting for a fix. If it was fixed, I would give it five stars.

This review is for a previous version of the add-on (5.0.1). 

Not Send Later's fault, but in any case, fixed in the next release

The incompatibility with Enigmail is not a bug in Send Later, it's a bug in Thunderbird, or more accurately, a limitation in Thunderbird's add-on integration framework. It doesn't seem fair to give Send Later a bad review because Thunderbird's framework isn't functional enough to allow Enigmail and Send Later to play nicely together without breaking the rules.

Having said that, the maintainers of Enigmail and I have worked together to find a way to "break the rules" collaboratively, and as a result, the next release of Send Later -- due out this week -- will be fully compatible with Enigmail.

Send Later Option Cannot Edit Rated 4 out of 5 stars

I love this option and use it every day for 3 different mailing lists, My biggest issue is that you CANNOT edit the content of something after you have saved it. You must delete the whole thing and rewrite it. NO FUN when something is 5+ MB in size !

This review is for a previous version of the add-on (5.0.1). 

In fact, you CAN edit scheduled drafts

If you double-click on a scheduled draft you can edit it just like any other saved draft and then reschedule it when you're done editing it.

Note that editing a draft removes its scheduled send automatically at the beginning of the edit, to prevent Thunderbird from sending the draft while you are in the process of editing it.

A fantastic tool that does exactly what it's meant to do Rated 5 out of 5 stars

It simply sends emails later! When you click "send later" it pops up a dialogue with half a dozen preset options to choose from eg "send in 30 minutes" "send in 2 hours", or the option to specify the exact time (to the second!) you'd like the email sent. It relys on Thunderbird running at the moment the send is required, but it's not daft - if it misses a scheduled send, it simply sends your email at the first chance it gets, the next time Thunderbird is run. Great little add-on.
