Can I stop or ‘un-send’ an email I sent by mistake?

Once you hit that Send button, you must assume that there is simply no way to stop your email from being sent ... even if it's to the wrong person.

//

I wrote an email from my Yahoo email account and sent to the wrong email address in Europe. Is it any way that I can retrieve the email I sent from the wrong email address and delete it before the wrong recipient can read my email?

No.

There are a couple of exceptions – one of which isn’t really an exception at all, but the answer you need to keep in mind and always remember is simply no.

Once email has been sent, it has been sent.

I’ll describe why that is and what those so-called “exceptions” are all about.

When you hit Send…

When you hit the Send button, the following happens:

  • If you’re using a PC-based email program, like Outlook or Thunderbird, the email is sent from your machine to your email provider.
  • The email is then sent from your email provider to the email provider of your recipient.
  • The email is then placed in the recipient’s online inbox “footnote”>1
  • If the recipient is using a PC-based email program, he downloads it to his machine.

Once an email leaves your outbox, you lose all control over it.

Two things are important to realize about that scenario:

  • The first three steps – up to and including your recipients’ online inbox – can often happen in seconds2.
  • Regardless of which steps have and have not occurred, it’s all out of your control once the sequence begins.

Once an email leaves your outbox, you lose all control over it. And I do mean all control over it. You cannot stop it. You cannot change it. You cannot track whether it’s been read or not. You cannot tell if it’s been forwarded or deleted. You can’t even know whether it’s been received at all unless you get some kind of response from the recipient.

Not really an exception: Gmail

Many people point to a feature in Gmail and tell me, “But, but … Gmail lets you unsend!”.

GMail's 'Undo Send' feature

No. No, it does not.

Read the description of that feature (available in the “Labs” section of Gmail options). All that this feature does is delay the send for a few seconds. In other words, when you hit the Send button, Gmail doesn’t send the mail.

At least, not right away.

After a few seconds, it does. And once it does send, then the Undo feature is no longer available for that message, because once email is actually sent, it cannot be un-sent.

All this feature does is give you a few seconds to change your mind. During that few seconds, the mail has not yet been sent.

An actual exception: Some corporate systems

“Corporate” here is really just a characterization because of course, these email systems could be used elsewhere. It’s just more common to see them in large corporations.

Some of these email systems have a real, honest-to-goodness un-send option.

However, there are a couple of requirements:

  • The sender and the recipient must both be on the same mail system. I’m not talking about Gmail or Hotmail or whatever, here. I mean that both sender and recipient likely work for the same company and use the same email system as provided by that company.
  • The email has not yet been read by the recipient.

It’s possible that an un-send function will actually remove your message from the inbox of the recipients.

The last item is hopefully obvious, but if they’ve read the message there’s no way to make them un-read it. Once seen, it cannot be unseen. You might be able to “remove the evidence” in that perhaps the message might have disappeared from their inbox, but even then, they could have copied or printed it before that happened.

And again, this is not, not, NOT available with the email services available on the internet and not something that would work between differing email services even if it was.

An embarrassing exception: Recall

Some email programs and some email system expose a function called message recall.

The intent was – like Return Receipt – to provide a semi-standard way to “recall” or bring back a message that had been sent. In other words, a way to un-send it.

And much like Return Receipt, it’s not implemented or it simply doesn’t work as intended in most email programs.

When I’ve seen this attempted, the cure seems much worse than the disease.

The problem is simple: when recall is used, it works by sending another email message to all the recipients of the original message that says:

[Sender] would like to recall the message [Subject]

Now, I’m sure that the idea is that the message would never be seen by the recipients and that the mail programs would just recognize some special headers and perform the recall function by deleting the original message from the recipients inbox.

In practice, that’s not what happens.

What usually happens instead is that everyone who got your first message by mistake now gets this second message drawing even more attention to the mistake.

I’m sure it works on some systems somewhere, but make darned sure you understand whether or not it won’t just make people take special attention to your original mistake. Much like a politician attempting to delete evidence from the internet, there’s a very good chance that all it really will do is make people take even more notice of whatever it is you’re attempting to hide.

The moral of our story

There is no undo send.

Even if there were, you still run the risk of people reading the email before you hit Undo.

Once email is sent, you lose all control over it; all control.

Bottom line: make sure you really mean it when you hit Send.

Footnotes and references

1: We normally think of web-based email services like Hotmail or Gmail having online or web-based inboxes. In reality, almost all email services provide web-based interfaces, even if they are never used. Email can appear in these web-based inboxes almost immediately.

2: Even though the entire infrastructure of email is designed to tolerate delays measured in days, and we occasionally see that, more often than not, email is currently delivered in a matter of seconds.

    Actually I beg to differ with “You cannot track whether it’s been read or not. You cannot tell if it’s been forwarded or deleted. You can’t even know whether it’s been received at all”.

    The first and 3rd parts are false (the 2nd is true). You CAN tell if it’s been read, if you attach a read receipt to the message. Similarly, if you request a delivery receipt, you can have the receiving system tell you when the message has been delivered to the receivers mailbox.

    Now for the caveats: Read receipts are often optional. The receiver can choose whether or not their email program will send them, some don’t.

    And the delivery receipt fires when the email enters the users mailbox. It does NOT mean that the receiver has seen the email message, just that it’s entered the users mailbox.

    Think of it like postal delivery. You get notified that the mail you sent has entered the users mailbox but you don’t know if the user has walked down to the mailbox and collected the mail. They might not get to their mailbox for two or three weeks, but the mail’s been sitting there for all that time, and the next time they get to their mailbox they’ll get the mail.

    Actually, I disagree. Sort of.

    Absolutely all those things are intended to do what you state. The problem is that they only work *sometimes*. ALL reciepts are “optional” based on the user’s email client, his or her preferences, and in many cases even the email server they’re using.

    What I’ve found is that reciepts are DISabled (or disallowed) a surprisingly high percentage of the time. So much so as to make them, effectively, useless, and as a result, pointless to recommend.

    I respectfully disagree with your comment “You cannot track whether it’s been read or not. You cannot tell if it’s been forwarded or deleted. You can’t even know whether it’s been received at all”. I use the program called MSGTAG (free version available) which lets me know when an email I have sent has been opened (actually viewed) by it’s recipient. And I understand that the paid version can even tell you how long the person viewed the email, whether they forwarded it, and various other specifics. I highly recommend this program.

  4. Leo Reply

    This program, and various so-called tracking mechanisms are also not guaranteed to work. They typically relay on HTML email and what are called “bugs” placed into the email. These bugs reference web URLS when the email is viewed. Recent versions of email programs such as Outlook Express and Outlook 2003 disable remote URL retrieval by default. While it can be turned on, it’s a step that people need to take, sometimes per email, sometimes per sender, and they often do not take that step. Email sent as plain text, and email read while disconnected from the internet will also cause these techniques to fail. But the bottom line is that these techniques are NOT reliable.

    A one chance in a million happened to me. I was Replying to a letter from a relative. In my reply I told about some problem I had with another relative .

    WELL…..After clicking on Send the person’s name I had wrote ABOUT appeared as well as to the one the email REPLY should have ONLY gone to. I was VERY VERY UPSET .

    I don’t know how in the World this could have happened!! The other persons name wasn’t on the original letter and I certainly didn’t click on it by mistake. I use Hotmail and this has never happened before……..and of ALL the names it could have put on it was the one I wrote about!

    If e-mails are held by the server for a while cannot they be returned to the original sender if they have been sent in error to the wrong address?

    I have notified support that I did this today 26 September 2005. I hoped the message (sent to the wrong person) could therefore be aborted.

  13. Leo Reply

    The mail is typically held until the recipient downloads their email. Theoretically, yes, one could remove the mail before they do so, BUT … I know of NO ISP that will actually take the time to do so. It it labor intensive, and most ISPs are simply too busy with other things.

    I typically pull my network cable when that happens to cause the send to fail. Then delete it from the outbox and reconnect.

    No, once it’s in sent items, it’s been sent. If you can delete it from the *outbox* you may be able to prevent the send.

    You can only retrieve an email sent by mistake if you have Outlook 2003 with Exchange server on both ends, sender and destination. Go to “Sent ” folder, open the email, go to Actions or Options, click on “Retrieve this message”. Then you can delete or replace the involved message, provided the destination HAS NOT read the email yet.

    The answer to this one is fairly obvious, but there is a way out…..if you live reasonably close to the
    sendee and they are not on broadband. Send them a huge file, 12-15 mb and then when they call you up with the download problem that they will be having nip round to their place and take over the download. Once it’s done, quickly delete the email sent by mistake and all is well. This of course is highly unlikely in a lot of situations but it worked for me.

    I do a lot of long emails and so often they are saved as a draft, over & over. I accidently hit the send on a junky draft that I was using to cut, paste, copy, etc. I was and still am quite embarrassed over it. I quickly sent them an email pleading with them to delete it without reading it. From now on, I will NEVER start composing an email with their name/address on it. The TO: line will be left blank until I am absolutely ready to send it. It was a horrible way to learn a lesson. Why can’t there be a verification window pop up like when you are deleting something? It should have the name on it to verify that you have even put in the right recipient, such as poor Kyle who thought he was sending an email to a friend but instead it went to the ex-girlfriend, who will probably always be an EX since she was the one to get the email. Placing these 2 questions in the window: Are you positive you are REALLY ready to send, and is this REALLY the contact you are sending to, both of those questions could really help the sender who is rushed or preoccupied to come back to earth and turn their porch light on. Isn’t that a possibilty for “PATCHES” to make happen? I am 100% the opposite of geek, and had to have a name for the dude/alien “inside my computer” who corrects/updates/fixes/ and sometimes turns my computer off when I’m not looking.

    I have just spent well over an hour that I don’t have anymore, trying to find a way to transfer my small list of address from one email account to one of my other email accounts without copying them down with the old-fashion method of pen & paper, and then individually, retyping the contacts into each mail account. Spent forever scrolling down this one info site thru hundreds of questions, mostly how do I find an email address, or I’m trying to find Uncle Joe, and even how can I get my boyfriend’s password, because I think he’s cheating on me, and then there was one that should have gone to Dear Abby such as, how can I get this boy to notice me?! Doesn’t even have anything to do with computers! Just thought of something, maybe there is a computer out in cyber space that is attracted to Patches.

    Anyway, between all that time spent looking for my answer I could have done it manually ten times over, and another 10 times with the time I’ve spent writing to a stranger! I’m suppose to be packing, and I’ve done 4 boxes with a closing taking place in 8 days. Eight days for and after living in this house for ten years with 2000 sq ft filled completely, along with a garage and 2 outdoor sheds. I’m the one that should be writing to Dear Abby, or for as chatty as this has become I should re-route to a chat room where I’ve never gone. I’ve never even spoken to a stranger on the computer, this is kind of like being on a an airplane giving the story of my life to the person sitting next to me! I have got to pack, time is still rushing by and here I sit, writing nonsence. God should have given us a pause button. I bet you would like me to click on delete. I’m sorry, I would delete, but its too long and I’m out of time. Did I ever ask my question? Whoops, I see a preview button, but I’m oout of time…

    Please forgive the lie, because I haven’t previewed it. If I delete I’ll never find out how to transfer an address(es), and now I don’t even have time to do it manually. I bet you think I’m sending this from the Looney Bin in Tim-buc-two! I forgot to put my name and email address down so this all came back, and as soon as I send it I’m thinking, WAIT, STOP, don’t go anywhere, COME BACK! And it did. So, what do I do, I write some more! But, hey, I found out I wasn’t lying afterall, because it wasn’t my comment (book) I was suppose to preview, so yes, I did read the article in full. I also looked around your site for a bit, and I will send you a cup of coffee, in fact I owe you a big bag of beans for having to read my bag of beans! I’ve not used PayPal for a couple of years, and I know my CC number is different, and I really don’t have time, so when I get moved… I really will, and I will even be able to afford the big bag of beans then because escrow check will be in hand. There is a story that goes along with the escrow check, but I’ll send that to Abby, nah – I’ve never cared to ask a newspaper for help, and certainly don’t understand how a newspaper can help. It’s probably one of Patches’ relatives that answer anyway, and most likely one of the nuts that everyone has in their family tree.

    Yes, I probably am writing this from the looney bin, since I think in this case its THE STATE OF MIND!

    So how do you propose people go about fixing this? I mean, what should you do if say, you sent an e-mail detailing explicitly what you would like to do with your girlfriend sexually if she was in New Zealand with you, TO THE WRONG PERSON?! Not even just the wrong person, but someone who would not even appreciate the humour in the situation. This is bad. This person is not in New Zealand. Not even in the same hemisphere, so running over to their house and deleting the e-mail is NOT an option. How do I fix this? Beg the reciever to disregard the e-mail? Any tips on a good way to go about this? Does this even work? Wouldn’t the reciever be too curious when they recieve an e-mail begging them to delete another e-mail you sent them? I need help.

    There is no technical solution. It’s been sent and you can’t unsend it. All you can do is send a follow up email explaining and appologizing, if that’s appropriate.

    Yes, there is a way to get an email back after it’s sent. I have found a new web service called YankBack — Since the rule is no physical addresses, I suggest you google yankback. I use it all the time. Not that I make damaging email mistakes often, but it’s handy for the little stuff, like not looking stupid when forgetting to attach something. You can recall or stop the email and just send it again with the attachment in place.

    One more do not save emails on your contacts because it is not safe once a HACKERS enters your email they will use your email to send fake advertisement to your contacts by selling fake products to your contacts and once your contacts HACK by the HACKER then it is a big credit card problem to you and your contacts.

    Actually you can stop an email from reaching the wrong person by deleting the sent email. First you go to your SENT Folder. Then you check mark the box next to the message you sent by mistake. Then lastly you delete the message from the SENT Folder, then it wont go to the receiver of the message after all.

    This is incorrect. It works only on some very specific email systems that 99% of average users do not use.

    I second that! Also, it wouldn’t hurt to have a pop-up that said “Review the TO”.

    So why haven’t the other email providers implemented an unsend feature? If the corporate systems can do it, so can the others. It seems like a desirable thing to have.

    Corporate systems can do be because they control both ends of the conversation – sender and receiver. For it to work elsewhere would require cooperation between all possible email systems and clients, and that’s just not going to happen. Besides, the very concept is flawed – someone could read it before you unsend it, leaving you with a false sense of security.

    There are email tracking services that tell you when email has been sent, received, opened, and can also be deleted.
    Available to anybody to use for a minor annual fee.

    And these services do not work reliably. Period. Email cannot be reliably tracked or traced, and there is no way to reliably tell if an email has been read or opened. More here: Do email tracking services work?

    One of the first e-mail providers I had, from what I can remember, had a feature that, when you SENT it, it actually went first into a “cache” which gave you a chance to reconsider before you finally sent it. That I liked! It meant two strokes instead of one, mind you, but it also gave you another “kick at the cat”, and a measure of “peace of mind. I remember a number of times of being REALLY thankful for that feature! Why not bring that feature back??

    Well i have used their services and found no fault with them at all, their services acted exactly as they advertised they would.
    It is a concern that if someone disagrees you just say they are wrong,lol.
    These email services are used by corporations, and small end users alike, and have been around a long time, and i dont think they are going anywhere.
    You tried them all???, that is why you stated they arent reliable???
    I have personally used the services of two and stuck with one, and have had no problem, at all.

    I’ve created an Outlook Rule which delays the sending of my emails for 25 minutes. This only applies if the email is marked “Normal”, so I can avoid the delay by marking it “High Importance” or “Low Importance”. Also, by scheduling a Send/Receive every (say) 30 minutes, you can also give yourself a chance to retrieve an email before it leaves your Outbox.

    I use this method not just to allow “second thoughts”, but also to correct errors, e.g. if I’m working my way through a big Inbox I might come across a later email which requires a change to what I just wrote.

    Hi Leo
    Ya certainly got a lot of comments on this article
    However to me ya are 100% correct again..the answer is lack of discipline, something that at my age was drilled into us at school.
    Did try to activate the g-mail labs thing, and although it does work, ya gotta be very fast, faster than is normally possible following an error in sending, so virtually useless.

    One “solution” when writing important/sensitive email is to remove the addressee/s first. Once sure, you then add the addressees. More work, but safer. Another “solution”, try to keep your email for a day first when writing angry email; you may amend quite a bit of the email…

    Leo,

    You missed a great opportunity to suggest disabling the ‘immediate send’ feature that’s in all-mail client programs I’ve used (maybe under a different name). This allows all e-mails to ‘cool off’ until the next ‘check mail’ is invoked. It can even avoid embarrassing situations by allowing the sender to see succeeding e-mails viewed in a session before any of the responses are actually sent. I preach this feature in my classes.

    Thanks for all the high quality info you provide your readers.

    Dale….

    In case anyone is really worried by this and to amend my earlier post I have found that Yuzo F’s contribution in G-mail can indeed be lengthened to 30 seconds. This of course is still just a sending delay and not really an UNDO. Is done simply (after first enabling in Lab’s) by scrolling Settings/general and increasing the time to a maximum of 30 sec’s. This to me seems a rather long time to wait to send an e-mail. Still to each his/her own.

    From all these comments you would think people are mis-sending emails each and every day! When this happens, wouldn’t it be better to be honest and admit the mistake with an apologising email? For people sending lots of messages (and making lots of mistakes!) perhaps it would be best to disconnect from the internet and review the addressees before reconnecting and sending.

    I mention this only as a point of interest, but I’m sure it was possible to cancel an email between AOL subscribers. This would have been similar to the corporate email system described in your article as AOL used a proprietary email system. It wasn’t possible to cancel an AOL email sent to a non-AOL address. I haven’t had an AOL account for several years so I have no idea if this is still the case.

    There is a tracking program called ReadNotify that allows you to retract an email if it has not been opened. However it will only retract the message, not who it is from.

    i remember back in day, windows 95 or earlier, that we were able to tell if it was received, read, and maybe more. thanks

    Yes, u can delete or recall your mail before receiver read it.

    when your email configure in Microsoft outlook 2007

    Go sent item which mail you want to recall or delete from receiver email.

    then click on other action button ,

    then click recall massage,

    then appear one dialog box now click ok.

    As outlined in the article “Recall” is notoriously unreliable – it almost never works. In fact, it can actually draw MORE attention to the message you’re attempting to recall.

    From time to time, there have been (and may still be!) the occasional encrypted user-to-user, web-based E-Mail service (usually fee-based) which allows one to cancel (“unsend”) messages which have been sent but which have not yet been retrieved (decrypted) by the recipient; this usually works by deleting (usually, securely deleting, although since the message is encrypted this is surely redundant) the message from the recipient’s inbox. However, in all such cases that I’ve ever encountered, the message cannot yet have been decrypted/retrieved by the recipient.

    This is however exceptional and requires both the sender and recipient to be using the same specialized messaging system. I quite agree that in general “unsend” is simply not possible. Indeed, I recall that there was at least one television commercial which made ridicule of this fact, since the unwary sender was left muttering “Unsend… unsend… unsend…” and hunting for the “unsend” key on his keyboard! (To the utter dismay of the advertiser, I haven’t God’s own notion what product was being advertised!)
