What is Self-Destructing ?
Self-Destructing is the most powerful, useful and reliable email tracking service that exists on the Web today. Put simply, Self-Destructing tells you when email you've sent gets read.
Are downloads or plugins required?
No. Self-Destructing already works with almost every email program available.

Does Self-Destructing do anything else?
Much more! For example, if your email is forwarded to someone else, we can notify you. In many cases, we can tell you how long your recipient actually spent reading your mail, and how many times they opened it and re-read it as well. If your email gets published somewhere without your knowledge, you can usually find this out, and where. We provide a mapping feature so you can find out the approximate physical location of your reader. We also have Self-Destructing Emails, Ensured-Receipt emails, proof-of-posting certificates, proof-of-delivery certificates, message retraction, and many other useful features. Keep exploring this site for more details.

How will you inform me when my mail arrives?
Several avenues exist:
Additional features are being added all the time. Please contact us at
How does the recipient confirm their reception of my emails, registered with Self-Destructing ?
Normally, this is fully automated. Once your email has been received, you usually receive an acknowledgement response instantly. You can also choose a banner announcement notice that will invite your recipient to acknowledge they read your email. With only one mouse click, they can follow a link to our site which tells them their message status has been confirmed, and that you have received their read response. This way, readers receive notification that you may be waiting for a reply.
Will my recipient know that I am tracking my email?
For every Self-Destructing email you send, you will be able to decide whether or not your recipient knows that it is being tracked. By default, we add a banner to all email you send; this tells the reader that the email is tracked, and invites them to manually confirm that they actually read it.
You have the option to turn the banners OFF (by selecting "none" for the banner style) for all tracked email you send, or you can add .silent.self-destructing.com to the end of the recipient's email address if you just want to send an individual tracked email with no banner attached.
How can I be sure Self-Destructing will work with my email service?
Self-Destructing works with all popular email and webmail services, and does not require any downloads or plugins to operate properly for both sender and recipient.
Self-Destructing works with AOL, Hotmail, Yahoo Mail, Bigfoot, and all web email sites, as well as Eudora, Microsoft Outlook, Pegasus, Netscape Mail, Outlook Express, Pine, sendmail, pop, mapi, Lotus Notes, esmtp, helo, and every other email client that can use internet email addresses.
My email software already features "Return Receipts." Why do I need Self-Destructing ?
The truth is, "Return Receipts" almost never work. The vast majority of all email software and users in the world do not support Return Receipts, and the few that do have usually disabled these by default. In the rare case that you send mail to someone who can support Return Receipts, they get prompted with a rude and intrusive message asking them to tell you that they read your mail, with the default action suggesting they cancel the notification.
With Self-Destructing , you get to choose how or if your recipient gets prompted to let you know they read your mail. The default action, which you can change at any time, is to always tell you when they have read it, and to let them know you asked. (Further, you may choose to support traditional Return Receipts if you want to use them.)
What is a Message Disposition Notification (MDN)?
Message Disposition Notification, or MDNs, is another phrase for Return Receipts. (see above)
What is a Delivery Service Notification (DSN)?
This is a feature (supported by some mail servers) that lets you know if and when your email arrived in the mailbox of your recipient. It gives no indication whether or not a message will be opened or even downloaded-only whether or not it got delivered. The most basic example is a "bounced" email; if you have ever sent a message to an invalid email address, you have experienced a DSN.
What is an Ensured Receipt?
"Ensured Receipt" is a method of sending email that guarantees the sender a read-notification when a recipient reads a message. This is possible because the body of your email is saved on the Self-Destructing server, and only the headers and attachments are sent to your recipient. When they open their email, it automatically requests the body from our server; afterward, we send the read-notification. It is not possible to get the body of your email without you getting this notification, so your receipt is ensured.
NOTE: If your recipient is not connected to the Internet when they read their email, they will have to re-connect to get it. Once you have received your read-notification, they are then allowed to keep the email, and can read it again offline if they wish.
What is the difference between Certified Email and a Proof-of-Posting Certificate?
They mean the same thing. When you send certified email, it is time-stamped and assigned a serial number, then digitally signed and appended with the secure certificate. The digital signature is then published for anyone to read at any time.
Should you need to prove at some later stage that you sent your email, the attached signatures provide admissible and certifiable proof that your email was posted on the date and time specified. Any popular cryptographic product can be used to verify the digital signature, and a regular signature-of-signatures is distributed around the Internet. This creates an indelible electronic "paper trail" that inextricably links the correct time of posting of your email to its attached signature. (NOTE: None of this reveals any information to outside parties about the email itself, including to whom it was sent or from whom it was sent.)

What is Self-Destructing Email?
These emails cannot be retained by your recipient. You have various ways to control the length of time a recipient is able to read an email, and you can choose whether or not to inhibit printing, copying, forwarding, and saving of email. At a time predetermined by you, email sent through Self-Destructing automatically erases itself-permanently.
NOTE: Although it is very difficult for your recipient to keep a permanent record of the contents of an email, they will still be able to keep your email address, the email subject, and all attachments you send. Also, as with every self-destructing email package, there is always a possibility a recipient might find a way to record an email anyway (i.e., photographing the screen).
Can I get back an email after I have sent it?
Yes. Use the "Ensured Receipts" or "Self-Destructing Email" features described above to cancel an email before (or even after) it has been delivered. Note that these features merely cancel the body of your email-not any attachments you send, email addresses or subject lines.
Do you read my email?
Never. For more information, view our privacy statement.
Is my email address safe with you? Will I get spammed?
Your email is completely safe. We never send, allow, or support spam of any kind, and we never give out our email lists for any reason. See our privacy statement and our terms of service for full reassurance.

Tell me everything about Forward-Tracking
Self-Destructing automatically tracks when your email gets forwarded to
someone else, or opened on a different computer.
Keep the following in mind:-
Why do some receipts have much less information than others?
Many factors at the recipient end affect the amount and accuracy of the tracking information you get back. Some of these factors include: their email program, whether or not they use a firewall or a privacy or content filter, and what their proxy settings are.
In combination with the above, the selection of advanced settings you have chosen also affect the amount and accuracy of your receipts. See the settings page for a detailed explanation.
Finally, the kind of email you send (eg: ensured, self-destructing, or plain tracking) also changes the amount of information you get.
Do you take other forms of payment beside credit cards?
Yes - there are dozens of ways you can pay us. Please send an email to us
if you are unable to use a credit card.
Can I get my tracking history in a spreadsheet or text file?
You can download a TEXT or CSV spreadsheet listing of your tracked emails. You must be logged in before you can use this:
http://www.self-destructing.com/self-destructing/messagescsv2.asp/mymsg.xls ...should automatically open up Microsoft-Excel (or other spreadsheet program) with your data already there (this is an XML download).
You can also use http://www.self-destructing.com/self-destructing/messagescsv.asp/mymsg.csv for an ASCII-text-only download.

Did they delete my email without opening it ?
In most situations, the only way you can find out if they deleted your email is waiting and continuing to NOT receive
any read notification. In some rare situations however - you will get a "not read" receipt that explains they
deleted your email without ever opening it: but this is dependent on their email provider setting this up, and not many do.
What does Location mean, and why is it wrong sometimes ?
Most of your receipts will contain "Location" information - this indicates the
approximate physical location of the ISP (Internet Service Provider) that the
recipient was using when they opened your email. This is almost always the same
town as the recipient.
We use a variety of data sources to determine this information for you, and the
method of tracking you use in combination with the settings on the recipient
computer determine how accurate our location display will be: if you get high
accuracy probabilities (eg: 95%) we are reasonably confident that we got the
location correct. If you get low numbers (eg: 50% or less) we are either not
confident that we could determine their location (the tracking data we
recorded was inconclusive), or we are not confident that the location we did
determine is likely to be correct (the location data for their ISP is not
