How Can I Tell If My Email has been Blocked?

How can I tell if my email address has been blocked? The email address I send to is good and working, the only problem is, it’s not working for me; have I been blocked? Is there any way of knowing if my emails ever get opened or deleted? And if I’m blocked, is it my email address that’s blocked or my IP address?

The ultra-short answer is: you cannot tell. There’s simply no way to know for sure.

Let’s explore why I say that.

One reason, or many

The root problem is that there are so many reasons your mail may not get through these days, it’s practically impossible to determine which reason is contributing to your situation.

On top of that, it could be a combination of reasons.

You could, indeed, be blocked

Stop! It’s certainly possible that your recipient has blocked you. All that means is that email from your email address is automatically discarded at that recipient’s end.

You will not get a notification; there’s simply no way to tell that this has happened. All you can do is ask the recipient to make sure that they haven’t blocked you. (I assume you’ve been in communication some other way, since you know that your email has not been received.)

It’s possible that your email address has been blocked (or black-listed) by the recipient’s email service, or by a spam filter along the way. Once again, there’s really no way to know whether this has happened. You won’t get a notification – your email will simply be discarded.

Your email could look “spammy”

More often than being blocked, email is often discarded or diverted into a spam folder because it “looks spammy”. Exactly what that means varies quite a bit.

I’ll assume your message isn’t attempting to promote body-part enhancement products or other common spam topics. Even so, it might make sense to review the content of your message, and the terms used, with the eyes of a spam filter in mind.

If  your email gets filtered as spam, once again, you’ll get no notification. It’s possible, however, that your message was placed in your recipient’s spam folder, and you should ask if that’s happened. If it has, make sure your recipient marks it as “not spam”, to train her or his spam filter that you’re not a spammer. It may take marking more than one message to do this.

Your email provider could have a bad reputation

Your email service provider’s reputation factors in to all this. If your email host is known to be used to send a lot of spam, then all the email that originates from it suffers.

Once again, there’s no effective way to tell if this is the case. Your email may be silently discarded, or it may be placed in your recipient’s spam folder.

Either way, you won’t hear about it.

Things to try

If you find yourself in this situation, I would start by asking your recipient to “whitelist” you, which may bypass some of the possibilities I’ve mentioned above. Exactly how he or she would do so, and in how many places (email program, spam filter, or email provider) depends on his or her email setup.

Another test would be to send using a different email provider, beginning with simple test messages that are unlikely to be flagged as spam due to their content.

  1. If I’m able to send an e-mail to an address how do I know whether I’m blocked or that my e-mail is just being either deleted/read?

    You don’t. There is no way to know for sure.

    • A new version of an operating system REPLACES the previously installed operating system. Your email address has no bearing on your operating system.

  2. Hi, I have a slightly different problem. Spammers have used my email id as an alias for many years (maybe due to poor server setup), causing my genuine business email to be listed on a lot of spammer lists for no fault of mine. Most of the spam seems to originate from Russia, but I still get the message that spam is originating from my IP address in some lists like Barracuda, which is not possible. How can I prevent my email id from being used as an alias and how can I get it removed from these filter lists?

    To the best of my knowledge you cannot. More here: Someone’s sending from my email address! How do I stop them?!



  4. @E.R.
    If you sister’s domain is blocked, the best thing she could so would be to contact her ISP (Internet company) and ask them about this.

  5. my e-mail is blocked,maybe someone use my emailI can’t open it..I would like to recover again and wish to change a new password..someone from security asked some question and need the answer about pre-paid card number,credit card 4 last digit number and expire date, I have none creddit card,such column still requested me to fill up the column how can I do that my credit card not available. So please re-open it for me again and a new password will be changed later..Thank you.

    This article discusses recovery options for the various ways that Hotmail accounts can be lost or compromised: What are my Lost Hotmail Account and Password Recovery Options?


  6. A few inquiries (to co’s I am seeking product info) of mine go unanswered ,, and I subscribed to a tech forum that their website would not let me access ,, I contacted the Forum (through F/B) and a Smart Admin there realized I was on some type of “Junk List” and removed me from it !!

    All in all I jus stay away from explicit web browsing and my E-mail addy seems OK ,, dating/singles websites seems to be the culprit that may have put me on a list ,,I recently returned toview one and now I wont go away !!

    How to get Off a Junk List Leo ??

  7. A few years back, I had a problem with my email provider’s domain being blocked by Hotmail. In that case I got a bounce message from Hotmail. Another way to determine if the problem is with the email provider bing blocked is to Google it, for example something like: hotmail gmx,de blocked.
    If the two emila providers are big enough, that kind of thing will usually show up in forums.

  8. Almost incredibly, I find occasional innocent e-mails from my ISP, in my Spam/Junk folder.

    Generally, they appear to be similar to the usual ISP Mail, no obvious reasons for junking them, the ISP Address is not in my reject list etc.

  9. There is another reason for emails not getting through and that has to do with the DNS (Domain Name Server). My ISP recently changed their email setup. I could send to everyone except one person on my contacts list. I contacted my ISP and they determined that the server at the other end could not make a Name match with my ISP.

    The two providers worked the problem out between them.

  10. If your IP address is what is blacklisted, you may find a workaround by powering off your router.

    Wait about 20-30 seconds, then power it back on. Chances are your IP address will be different unless you have a commercial account.

  11. As test, just send an email to yourself.
    Also, if you use an email client such as Thunderbird, go directly to your email at your ISP. In my case it is Verizon.

  12. Hi Leo, My daughter and stepson have moved from Germany to USA. They had a .de
    prefix on their email address. I would think their account in Germany is closed.
    How can that assumption be checked. I sent her a couple of mails. Have gotten no
    messages from her browser company.

  13. I’d had a problem with lost emails over the years, often from websites sending me password-resetting emails. I finally had it happen with a site where I knew the webmaster, and he kindly traced the path of the e-mail he sent. He was seeing messages like:

    “Jun 10 20:27:26 xxxxxxx sendmail[15537]: q5ANsFqg015464: to=, ctladdr=<xxxxxx (500/100), delay=00:33:01, xdelay=00:16:49, mailer=esmtp, pri=8042339, [], dsn=4.0.0, stat=Deferred: Connection reset by"

    (x's replacing actual email addresses). Which seemed to place the blame squarely on mi ISP's (Verizon's) doorstep. I could never find anyone via Verizon's custome "support" who could explain this, much less fix it, so I use another ISP now.

    So, if you can talk your sender into doing a little work to find out where his mail is going, you might find the cause, although that doesn't ensure finding a solution.

  14. I have an undesirable person who sends unwanted unkind emails. I used the Blocked option for his aol address, but I still get them. What message is he getting on that end when he trys to send an email?

    • More than likely he won’t get a message that he has been blocked. Your best option is to check your provider’s blocking rules and make sure his address is entered correctly. Sometimes taking a few minutes to read through any help files, and check through options will succeed.

  15. If I press turn off all emails on YouTube settings does that prevent people from seeing my comment or receiving it through email because I did click turn of emails on this settings page but I turned every one of them on the settings page on one by one its just I don’t get any replies are they ignoring me or am just not seen there should not be an option that disables anyone to stop seeing my posted comments so I want to make sure.

  16. Very good suggestion, thanks. But my email id did not work at present and it could not be recognised. I tried hard to open
    the same but failed. Anyhow I like to registere new email it within a short period.

  17. I see my emails with attachments in sent items but not received by recipients, while all the emails sent within the country are received and are shown in sent items. How I should resolve this problem. I am using an yahoo.account.

    Thank you

  18. People keep saying if you include links in your email that will get blocked. I totally disagree with that. Can anyone confirm that links in emails do not cause your email address to get blocked?

    • Links alone are not enough – I include links all the time. HOWEVER links to KNOWN BAD (or even “possibly bad”) websites and domains could cause your message to be considered spammy or be blocked.

  19. Hello! Can an email, sent to my account, be blocked by another person? I was waiting for a very important mail and it appeared in my inbox 3 days later, as it was not seen by me. Is it possible? Thankyou very much

  20. if someone found just email then what will he do i means does he hacked account and any illegal activity then what will do in this case if v give email to unknown person

  21. I have sent multiple emails , and it shows in my sent folder they were sent, then says draft. Did he get them, read them or all just go to my draft folder?

    • If the email is in your sent folder, it means that the email program of website had check that it’s been sent. The fact that a copy is in your drafts folder is no indication that it hasn’t been sent. As for the question if he got them and read them, there’s no sure way to tell if the email was read.

    • No real way to know. I’d have to know what email server AND program you’re using to start. Best might be to ask one of the recipients if they got it.

    • I get a bounce back message from an email address I have sent messages to for some time and it’s the only one to do that . I can send emails to myself with no problems . Could it be on my side or the one I’m sending messages to ?

  22. One of the things we sell is industrial wire strippers, for reclaiming scrap metal from discarded wires. I’m embarrassed to admit that it took me way too long to realize the word “stripper” was in the brochures we were trying to email…which, of course, spam filters don’t like.

  23. hi, I hope I ask this right and get an answer. A friend that sends group emails is blocked by other friends… I am told that somehow he is able to use my replies to his emails to get emails through to people that have blocked him. Is this possible?

  24. I am in the UK and know many of my emails do not make it as friends have told me. My normal mail address is not a commercial one and when checked my server is not a source of spam. All mail settings on my server are correct. My experience has been that it is often organisations who are using services such as mimecast and other American email security services that are at the root of the problem. I believe they are using badly written software which is really scrweing up mail delivery. Other peopl have told me they are increasingly getting the same problem. Time for a major rethink on email security?

  25. I have the new software put out by verizon (who is partner to AOL)
    hey want me to sign up with a new account. I filled out the info but do not have a cell phone number. They have blocked all my emails incoming and outgoing. Why do I need a cell number?

  26. Hi
    If you send an email to someone and you get an auto reply back sayin there on annual leave
    And you know that the person is on holiday does this mean they have received your email
    Many thanks.

    • Not necessarily. It could mean it’s been discarded, it could mean it’s in their inbox. There’s no way to know. If it is in their inbox, of course there’s no way to know if they will actually see and read it, ever.

  27. I just tried contacting someone at this email address {Email address removed} and I can’t email her. How do I find out if she blocked me?

  28. Hi Leo, I sent an email that was returned with the following message,

    Your message to {email address removed} has been blocked. See technical details below for more information.
    The response from the remote server was:
    550 permanent failure for one or more recipients ({email address removed})
    The message included 2 attachments that said mime-attachment

  29. How Can I Tell If My Email has been Blocked?
    Send the same email using “Disposable Temporary E-Mail Address” and if it gets delivered that means your email is blocked. Please correct me if I am wrong

    • That’s a good idea, and honestly is really just “send from another email address”. Only caveat, of course, is where you get your disposable email address. I just have multiple email accounts that I use as needed at different providers.
