Even if MDNs are not actively forged, they may be lost in transit.įurthermore, Google warns us about the use of read receipts:ĭo not rely on read receipts for certifying mail delivery. Although read receipts generally work across email systems, you may sometimes get a receipt for an unread message or not get a receipt even though the recipient has read the message. MDNs may be forged as easily as ordinary Internet electronic mail and whilst they can provide valuable information to the mail user, they cannot be relied upon as a guarantee that a message was or was not seen by the recipient. In fact, the Message Disposition Notification RFC 3798 is quite clear about the legal considerations of MDN messages: However, they were not intended to prove delivery of an email to a person, but as a way, more or less reliable, of making sure that the few servers that were online at the time were up and running and that emails got to destination. Read receipts are part of the Message Disposition Notifications (MDNs) and exist since the late 1970′. In any case, read receipts aren’t a reliable way to prove email delivery and obviously they don’t constitute legal evidence. But the truth is these systems are not reliable either as technology sometimes fails to recognize when an email is opened or not. There’s also email tracking systems that install a pixel in your emails to know when they are opened. This system fully relies on the recipient, as he/she has to manually return the read receipt – which means that you’ll probably get no answer in many of the occasions. A message is displayed asking the recipient to push a button to manually return the read receipt.
