If you don't want junk email, here's a way to say so strongly


[Feedback]  You can warn off spammers in a reply

This page gives you a strongly-worded reply that you can copy and send to junk emailers (spammers).

The reply basically says that the spammer must pay you $10 for each further email message he sends to you. It's available free of charge to everyone. It doesn't cover telemarketing or junk mail; if you don't want those kinds of junk either, use JUNKBUSTERS DECLARE separately.

This technique uses ideas similar to those pioneered by Private Citizen Inc. Since 1988 they have been helping people to collect ``fees'' from telemarketers who call them after being told they must pay if they do so. Private Citizen reports that its members have collected more than a million dollars to date.

Although some of the details below (such as the price of certified mail) are specific to the US only, the general principles should be applicable in most countries.

This page is intended for individuals. A page on what organizations can do to stop spam is under construction.

[Feedback]  Disclaimer and summary of the options described below

We are not lawyers, so don't take anything on our site as legal advice. We don't promise that what we describe will get spammers to leave you alone. It's up to you to get any advice you need to decide whether you should try these options: they come with no warranty.

  1. If you have the true email address of the spammer or the company that sent the spam, you can reply with the Notification and Offer given below, which basically says that you are unwilling to receive their spam for nothing, and that if they send you any they will have to pay. The return email addresses that spammers give are usually fake and replies rarely get through, but sometumes they do. Likely to be more deliverable are the post office boxes where they ask you to send your money.
  2. If a spammer annoys you so much that you're willing to spend a couple of extra dollars to get their attention, you can use certified mail to send them (or the company that delivers their spam) a Notification and Offer. If the spammer keeps sending you spam, you can show the evidence to a lawyer and ask what can be done to stop them.
  3. You might want to keep copies of the spam you get after you reply with a Notification and Offer, in case you or one of your friends decide to demand payment for it.

[Feedback]  Tracking down the spammer

In order to address your Notification and Offer to spammers it is necessary to find an email address or preferably a postal address. Some spammers include phone number, postal address or email address in the body of the email, but these should be treated with suspicion. Junk emailers often use ``spamouflage:'' fake addresses in the ``From,'' ``Sender,'' and ``Reply-to'' fields. A somewhat more reliable indicator of the organization that delivered the spam can be found in the the domain name (the partial address after the ``@'' sign) given in the ``Message-ID'' field (which your email readers may not display unless you request it). Some spam factories have their own domain names, in which case you can try sending your reply to them, but it is more often an ISP, in which case you should complain to them. You can type the domain name into Internic's whois form to get the details on the organization. Most ISPs work hard to stop spam, but lately a small number have become tolerant or supportive of spammers. Our Links page lists several web sites where you can learn more how to track down the people who send spam.

[Feedback]  Option 1: Replying to each spam with a ``Notification and Offer''

If you do get a good return address, you can send a reply consisting of the following Notification and Offer and copyright notice. At the end you can also add a list of the names and email addresses of other people who permit you to include them.


I do not want to receive uninvited solicitations by email (``Junk Email''). I am unwilling to receive Junk Email freely because it costs me time and money. If you send me any Junk Email other than on the terms of the offer set out in the following nine points, I will take this to mean that you plan to use what I offered you without paying for it. If you ever try to do this I reserve my right to take any action available to me without further reference to you. Actions available to me include taking proceedings against you for negligence or breach of contract, which may result in substantial damages being awarded against you by a court. The unauthorized use of my computing facilities may even be a crime.
  1. I offer to receive all further email from you on the terms set out below. If you send me any solicitation by email without my express prior written consent this will be taken as your acceptance of this offer.
  2. For the purposes of points 3 and 4, you will be taken to have sent any email sent by any entity apparently associated with you for the purpose of sending email solicitations.
  3. You must pay me ten US dollars for each such item of email that you send me.
  4. You must pay me ten US dollars for each copy of each email solicitation that you send to anybody or any email address referred to below, even if you don't send a copy to me. You may also have to pay other persons as well if they have sent you a similar offer.
  5. I may join with any of those persons for the purpose of efficiently collecting your payments.
  6. You must mail payment by certified check to me within five working days of the transmission of the email. If you do not know where to send payment, you must state this in the email and give me an easy way to tell you.
  7. Each email item must be uniquely identified, and each payment must clearly identify the relevant item or items.
  8. You must tell me your name and full business and residential addresses in each email message.
  9. I may vary the terms of or terminate this offer at any time (even after you have accepted it). Any new terms will apply to all email you send after you have been notified of a variation.

Everyone has our permission under the GNU GPL to copy this and distribute it. What you do with it is your responsibility of course, and we don't guarantee it will silence the spammer.

The Notification and Offer uses the common idea that you may have to pay if you do something that costs someone else money. Whenever you refuel your car or call a 900 number you are told how much you will have to pay, and you don't have to accept what is offered to you. Starting to fill your tank indicates your acceptance of the offer, which obliges you to pay, even though you didn't sign a contract saying you would. The Notification and Offer above tells the spammer that receiving junk email costs you money, and that you require certain payments if he sends you any.

Don't plan on getting rich from spammers: most of them have shallow pockets. And please don't send huge numbers of these replies or include an enormous list of email addresses: this can make everybody suffer. Certified mail has two advantages over email: it doesn't slow the Internet, and it gives you a way of proving that the spammer received your offer.

We don't recommend sending an email copy of the Notification and Offer to the webmaster of the ISP given in the spammer's email address. Those administrators get huge numbers of these reports (and many follow them up and cut off the senders' accounts), so please keep any reports you send them brief: just the full email header information and the first few lines of the solicitation are usually all they need. Some people ask for the account to be terminated and include the sender on the carbon copy list. Many ISPs maintain an account called abuse for such reports, though some ask for such mail to be sent to support, postmaster, or other names.

The Notification and Offer doesn't apply to responsible ISPs who have policies prohibiting junk emailing, because under point 2 they are not associated with the sender ``for the purpose of sending junk email.'' It's only in the rare case of a spam factory that this applies.

[Feedback]  Option 2: Publishing your ``Spam Offer'' on the Web

We experimented with the following idea but have not found people adopting it, but we leave it here for anyone interested in developing it. Others skip down to the next section.

Any group of friends could agree among themselves to team up against spam. They could include each others' names and email addresses in every Notification and Offer that they send to spammers. They could even arrange to divide the cost of suing a spammer and to share any money a court awards them.

This idea of teamwork can be scaled up. People with web space can let all spammers know who they should not spam, by posting their addresses in notices on the Web. With the right permissions and software, anyone can gather these addresses together. You can help make this work by using your web space to publish the following Notice of Permission, which tells everyone that they can include your email address whenever they reply to spammers with the same Notification and Offer.

I permit anyone who receives an uninvited solicitation by email (``You'') to include my name and my email address(es) given below in Your reply to the sender or the sender's agent, on the following four conditions.
  1. Your reply must consist of the Notification and Offer quoted here (or any similar version published by Junkbusters) and the copyright notice. It may also include the names and email addresses of others who have also issued this same Notice of Permission.
  2. The reply must be made in a responsible and reasonable manner. It must not be sent in large or bulk email messages.
  3. You must not do anything that imposes any cost, liability or obligation on me.
  4. Your reply is Yours, not ours. You are not authorized to act on my behalf in any way.
I permit my name and my email address(es) below to be included in lists published on the Web of people who have adopted the same Notification and Offer and Notice of Permission.

[Feedback]  Option 3: Replying by certified mail

Suppose the spammer sends you more spam after you reply by email with your Notification and Offer. You could ask him to pay, but he might not respond, or if pressed he might claim that your offer never arrived (email is so unreliable). The usual way that lawyers prove a message arrived is to send it by certified mail.

The US Post Office charges an extra fee (about $2) to certify receipt of a letter, but a single reply can contain a large number of email addresses. As well as your own email address(es), you can also include those of friends who ask you, and those of people who publish Spam Offers on the Web. A long list might result in bigger damages being awarded against the spammer. On the other hand, it would probably be easier to convince a judge to award you $30 for three items of email sent to you than ten million dollars to each of a million people. The choice of whether to include others is up to you. It is probably worth including a copy of one of their email solicitations that you have already received.

To send certified mail, get PS Form 3800, Receipt for certified mail, from the counter at any Post Office. You tear off the green and white stub, stick it to the front of your reply, and mail it as usual. You keep the other part, which is your numbered receipt. You don't have to lodge the letter at a Post Office, but if you do, the clerk will postmark the receipt, which might come in handy. The office that delivers the article will keep a record for you for two years, and you can ask for this by presenting your receipt at any office. If you really want to know as soon as your article is delivered, you can pay an additional $1.35 for a return receipt. You can also pay more for ``Restricted Delivery'' to a particular person, requiring a signature by him or his agent. Registered mail is a more expensive service, but we have had reports that it has advantages, so we are investigating it.

Postal services around the world have similar options, but they sometimes go under different names. In the UK the service is called ``Recorded.''

[Feedback]  Option 4: Keeping copies of the spam you get, to claim payment

If you think you ever might want to help nail a spammer, you may want to start saving the spam you receive. Even if you don't want to demand payment yourself, you could share your collection with any friend who included your email address in her Spam Offer, so that she can ask the spammer for money for spam he sent you.

We do not recommend emailing people you don't know with news of your spam collection. This may annoy them as much as spam itself. To help our clients coordinate demands for payment, we may propose a way to automate the sharing of such information on Usenet, if a way of doing this can be found that doesn't overload it. Suggestions are welcome.

We don't want to encourage litigation, but everyone (especially spammers) should know that it is not necessarily a long or horribly expensive process.

The cost of filing suit in your county's small claims court is most likely between $20 and $120. The Clerk should be able to tell you and give you the form to fill in. These judges are probably more accustomed to making decisions about whether a dry-cleaner ruined a leather jacket rather than anything to do with the Internet, but small claims cases are generally decided far more swiftly than criminal trials, where the stricter criterion of ``beyond reasonable doubt'' applies.

We're interested in feedback on experiences with such actions. Our clients might also want to share news of their experiences with this technique. They could post to Usenet or publish on their web pages their answers to questions such as these.

  1. Did a particular spammer stop after receiving a Notification and Offer by email?
  2. Did he also stop spamming any of the other email addresses you included?
  3. Did he stop after receiving it by certified mail?
  4. Did he stop after being served a summons from a small claims court?
  5. Did he settle (pay you some amount) after getting the summons?
  6. Did he deny that his company sent the particular piece of email? If so, did the judge consider that the truth was more likely that the company did send it?
  7. What judgment did the court reach, and what were the costs?
If everyone knows how spammers are reacting, they can act together to stop them.

[Feedback]  We need better law against spammers

We are not lawyers, so we can't say whether individual small claims or larger class action suits against spammers using these methods are likely to succeed.

Some people might send these paper notifications because they oppose spam on principle; others might just be hoping for a bigger payback. Spammers can't avoid receiving these lists by making it hard for any single person to send them. Even if our service were shut down, everyone could easily continue publishing and sending Spam Offers.

If you're interested in issues such as compliance, enforcement, and copyright, you might want to read the other pages on this site about JUNKBUSTERS DECLARE; many of the details are similar or comparable. But we don't recommend making this kind of offer to telemarketers or junk mailers, because you already have other ways to force them to obey you. For example, if you fill out a ``prohibitory order'' against a sender of junk mail and they continue to send you their junk, they risk being prosecuted as criminals. And the Post Office won't charge you a penny to tell them this.

We believe strong specific laws is necessary to ban spam. For more detail see our Congressional testimony on this topic.
