Single-Piece Mail

Industrialising outgoing post

Single-piece mail? This term refers to the stream of letters and mailings that, because they are generated gradually by companies and public services, elude industrialised and automated production.

In order to prevent senders from having them stamped at the single-piece rate, IN Groupe offers an electronic approach. It’s simple: the messages are sent to a virtual printer and then captured by IN Groupe’s secure servers, before the post is printed and distributed en masse. This approach gives our customers access to industrial postage rates, with no minimum volumes and no subscriptions.

A web portal at the heart of the process

The customer can manage the entire process securely via a web portal: tracking the status of the post, archiving it, etc. They can also opt for a multi-channel service: instead of printing their post using a virtual printer, they can send it via e-mail. All they have to do is set up the business rules to do so.

E-registered letters

Utilising the same principle as electronic post, IN Groupe has set up anelectronic registered letterservice. We ensure the electronic sending of registered letters in full compliance with the regulatory frameworks in force in terms of digital trust. We therefore guarantee secure identities and exchanges, providing our clients with great flexibility of use.

In accordance with the process defined in article 44 of the eIDAS regulation, an Electronic Registered Letter (ERL) has the same probative force as a registered letter on paper.

Support through change

In addition to this industrial service, IN Groupe can also take care of the change management process for our clients. Outsourcing post calls for a change in habits (abandoning printers, using a driver, switching to electronic post). This support is one of the key factors of success.
