Giving your email communications legal validity

The registered letter with return receipt from your computer.

PEC allows you to send emails that have the same legal status as a registered letter with return receipt, providing proof of the time it has been sent and delivered.

Thanks to this service, companies, professionals and public administrations can interact in a secure, certified way, making formal communication simpler.


How it works

  • emails are certified because the service Provider issues a receipt that constitutes legal proof that the message and any attachments have been sent
  • likewise, the recipient’s service Provider sends a delivery receipt for the PEC message back to the sender
  • these receipts with time and date stamp certify that the message has been sent and delivered in its original form
  • PEC is mandatory for all incorporated companies, public administrations and professionals enrolled in registers and lists


  • eliminate the cost of paper, toner and post office fees
  • save time and avoid queues at post offices


  • it is effectively immune from computer viruses thanks to the antivirus services and the certification of the sender
  • it can be admitted as evidence in the event of a dispute with third parties
  • it uses secure and encrypted protocols


  • you can use it with your own email application
  • it can be viewed from any web connection
