UnSend Email lets you retrieve those mistakenly sent e-mail messages

UnSend Email lets you retrieve those mistakenly sent e-mail messages

Ever sent a message then instantly regret having done so? Wouldn't it be great if you could unsend that e-mail. Gmail has this an option available when you send an e-mail, you have about 5 seconds to hit the Undo button before your message has been sent away, though you can increase this time delay in the Settings. A developer has brought this same function to BlackBerry 10 with an app called UnSend Email. Read on to find out more.

UnSend Email is brought to you by the developer of Hub++ (and more), seeing a need for such a feature. The way it works is that the UnSend Email app will intercept the e-mails you send and will hold it for a duration of time before fully sending it off. During this time it sits in the hold queue where you can unsend it. You will find the sent e-mail message within the UnSend Email app. From the Hub tap and hold the message, tap Share, then UnSend Email and it will open the app. Just tap the message you want to unsend and it will stop the sending process and keep the message as a draft in the Hub.

If you had a few e-mails sitting in the list, you could hit the Unsend All icon on the bottom to stop the sending process on all the pending messages.

Within the settings of the UnSend Email app you can set the hold duration. By default, the setting is set to 30 seconds. You can set it from 5 seconds and go all the way to a 10 minute delay. There is also a setting to have your device vibrate when it finally sends the message if you don't unsend it. All sent messages disappear from the list within the app.

At the moment if you're running an official OS, by that I mean anything below OS 10.3, you can use the app for ActiveSync accounts only. If you've jumped in and loaded up OS 10.3, the UnSend Email also supports IMAP and POP accounts. Within the app settings you can see the accounts that will work with UnSend Email.

UnSend Email runs headless, so there is no need to have it running in an Active Frame. On paper, this is a pretty neat app to have, probably something that could be native but always nice to see developers fill gaps like these. A great use for it is for those times when you forget to attach a file to an e-mail. It's somethng you realise almost as soon as you hit Send, with this app, you can quickly unsend the e-mail, attach the file and re-send. My only issue is that I don't need the delay on all e-mail messages I send but I guess, it's nice to have that buffer.

If you're interested in the app, it is available for all BlackBerry 10 device models and costs $2.99.

Have you NEVER forgotten to attach something? Have you NEVER said something you wish you hadn't?

God knows it happens to me!

Thunderbird has a really nice feature that reminds you if you write attach or attachment but haven't actually attached anything. Would be nice if BB10 had this too.

Sent a job application yesterday with a cover saying please accept attached resume as application for employment in your establishment. Guess what I didn't attach :( let's hope they actually open the second one.

I sent an application with what I thought was my resume but was instead a cover letter for a totally different company. The guy emailed me back and said it looked interesting and told me to send me resume still....got the interview still like a bawse!! Moral of the story is: Just because you got away with it once doesn't mean you shouldn't still be careful..lool

Pimp slappin iGeeks and Droinerds with my Q10

Think twice? Really? :-)

Think once first! If at all. Then worry about thinking a second time....

"No Q10?" -> "Buy from Chen... "

The dev could turn it into the app featured in "Girls" by only delaying messages sent to some addresses. Ideal when drunk messaging an ex :D

I've always wondered why the BlackBerry 10 doesn't have a drunk texting prevention app like those found on ios or droid. Where you set the hours to lock out whatsapp, FB msg, SMS, bbm etc, unless you unlock with a tough math question.

Don't you know that for anything useful on a BlackBerry you need to invest tens of $k in infrastructure and have BES licenses? ;)

Good for what it does I suppose... but how many times do you send an email you regret really?

Posted using my Q10 device

Exactly. Hitting Reply All when you intended to send to only one person can really have negative consequences. When dealing with contracts, it can be a costly mistake.

Posted from my awesome Q10 via CB10.

Just wondering, usually how long would it take before you realise the mistake?

I would assume it would be either when someone informs you or much longer period than what the app time period to undo the email.

How often have you received notification from an email sender to recall the email, only that it's too late.

I love those email recalls, I usually respond with the line "too late " :)

I would rather get to the root cause of the problem, which is think about what is being written and who is it being sent to.

I agree OJ, sure I have sent emails and/or text messages (even BBM messages) where I regretted sending almost immediately but as people we need to look inward to get a grip on what spews out of our mouths.

How does it work technically ? Is it a "man-in-the-middle" like the LinkedIn feature that was removed a few months ago?
In which case your email flows through the email servers of the third party...

I think the message is held in a queue on your phone for x period of time before it's actually really released. Think of it as a delayed send button or a send button that now should say "Send in 2 minutes".

Classifieds Canada and GeoYeo App all the way!!!

When I've sent an email, its usually gets through instantly. However I think this app slows it down for X period of time...

Please note that, it is not just Stopping/slowing the email. UnSend feature is just one use case. It is the ability to intercept the outbound emails and act on it. That in itself could have broader use cases.

Perhaps this feature opens up a 'denial of service attack ' opportunity on those mail servers those has this feature?

That's exactly what it is the default delay is 10 seconds which you can edit

If in that time you wish to edit the send then you long press on the message in HUB and you select unsend from the option

Remind me please, was this an option native to BBOS7? I seem to remember something like that, no?

I like my coffee BlackBerry Black! What?

I believe BlackBerry used to allow us send option for exchange users. I seem to remember doing this for my work account on my legacy BlackBerry.

Agreed though this should be a native tool so good on the developer for introducing it to BlackBerry. I hope they get the support for users to continue to bring great native apps forward.

A slow climb to the top is always more rewarding. Sent using my BlackBerry Z10.

Brilliant!!! This is one I could use. Mistakes happen all the time, nice to have the opportunity to recall a message.

I've always believed red head women are always temperamental. I believe it should be pre downloads for all red heads.


I sense your blood boiling after reading my post :)

So does this mean that I am giving the developer access to every email I send? Doesn't sound very secure but maybe I'm missing something.

Posted via CB10

No, it's just like in the old days where mails were first placed in an outbox folder and after a specific time interval the mail client checked for new mails and after that sent the mails in the outbox. So, don't worry!

If anyone finds this application useful then i guess this is good news for them. But essentially what it is doing is enabling poor self discipline. At the start maybe 10 seconds is enough. But how long until you subconsciously say "I've got 10 seconds to recall this" and just hit send. Eleven seconds later you realize a mistake. Too late. How long until you have the delay up to hours and your boss starts wondering why it takes so long for you to answer.

There is a saying, a bell can not be unrung. Eventually an email has to be allowed out on its own, and there is no recalling it after that. Much better to develop usage habits like using the draft feature.

An app is an app, can't complain, but certainly not something I would be using. Not that there isn't a need for it based on usage / user.

BlackBerry needs to purchase this code from the dev and bake it in!

This goes along with having ultimate control of communication, and that is what BlackBerry is know for.
