Certified email

Legal value for your email communications

Simplicity

How it works

  • the email is certified because the Operator issues a receipt that constitutes legal proof that the message and any attachments were sent
  • similarly, the recipient’s Operator sends the sender a delivery receipt for the certified email message

  • certified email is mandatory for all companies, public administrations, and registered/listed professionals
