Certified electronic notifications (electronic "burofax") as an alternative to the postal "burofax"

The postal "burofax" is the means of communication with the highest probative legal value because the delivery service provider certifies its content and delivery, identifying the recipient and collecting their acceptance. However, the use of paper as a medium for content makes it slow and expensive, especially for mass mailings.

The European regulation eIDAS, applied to electronic communications, allows these postal notifications to be made electronic with the same legal value.

When you need to give the maximum legal value to sending an electronic communication to a recipient, the MailTecK & CustomerComms Certified Electronic Notification service accredits the provision and acceptance of the notification by the recipient, certifying the content, time of sending, reading and acceptance by the recipient with the same legal value as a postal "burofax".
