What is the difference between digitizing mail and outsourcing it?

Digitizing mail means scanning and archiving it, usually in-house: someone in the company opens, scans and files. Outsourcing goes further: a specialist provider physically receives your mail at a dedicated address, scans it, makes it available online and also handles your outbound sending (hybrid mail). You never touch paper again. Outsourcing therefore covers inbound, outbound and archival at once, whereas in-house digitization often only deals with inbound.

How do I redirect my mail to an external provider in Belgium?

There are three routes. The cleanest is to give a new address to your correspondents (suppliers, banks, administrations), but it is slow. The fastest is bpost mail redirection, a paid service that automatically forwards your mail to an address for a set, renewable period. Note that bpost redirection does not necessarily cover every item, in particular some administrative registered letters. For a new company, it is simpler to declare the provider's address or a dedicated address from the outset.

Is outsourcing my mail GDPR-compliant?

Yes, provided the relationship is framed properly. The provider becomes a processor under the GDPR: you must sign a data processing agreement (article 28) describing the purposes, retention periods and security measures. The hosting of scans and the archive must be located in Belgium or the European Union. Access must be restricted on a least-privilege basis, with encryption and logging. This activity must appear in your data processing register. A serious provider supplies these safeguards spontaneously.

How much does outsourcing mail processing cost for an SME?

For the inbound side via a digital mailbox, expect roughly €50 to €200 per month depending on the number of items scanned, sometimes with a fee per re-shipped original. For the outbound side in hybrid mail, billing is per item: around €1 to €3 per simple letter (printing and franking included), more for a registered letter. Weigh this against the 10 to 20 hours of internal handling per month, plus equipment and software. For a mid-sized SME, the investment often pays back within a few months.

When does outsourcing mail really make sense?

It is especially relevant for multi-site companies wanting a single mail address, remote teams or organisations with no fixed office, structures subject to seasonal peaks (tax deadlines, campaigns) and companies whose executives travel often. Conversely, a very small structure receiving only a few items a month probably does not need a full provider. The tipping point is reached as soon as mail takes more than half a day a week or creates deadline risk.

Why outsource mail, not just digitize it

Digitizing your mail in-house solves one problem: paper. But someone still has to open envelopes, scan, file and — for outbound — print, fold, frank and take it to the post office. Outsourcing goes one step further: you hand all or part of that chain to a specialist provider, inbound and outbound.

In practice, a Belgian SME that outsources its mail never touches an envelope again. Inbound mail arrives at the provider, who scans it and pushes it into a web interface. Outbound mail leaves as a PDF from software or an API, and the provider prints and posts it. This is what people mean by an outsourced mailroom or external mail processing.

This article covers both halves, the practical setup with bpost, the GDPR question, real costs and the cases where outsourcing truly pays off. For the big picture, our complete guide to business mail management in Belgium is the starting point.

What an outsourced mailroom really is

An outsourced mailroom replaces the internal mail room with a provider. Depending on the contract, it can handle:

Inbound: physical reception at a dedicated address, opening, OCR scan, online delivery, forwarding or secure destruction.
Outbound: printing, enveloping, franking, bpost drop-off — including registered mail — from your digital files.
Archival: legal retention of documents (7 years for invoices in Belgium) with faithful reproduction.

The difference from a plain scanning provider is that the external provider becomes your operational address and your dispatch desk. You drive everything from one screen.

Inbound side: the digital mailbox

The heart of inbound outsourcing is the digital mailbox (or virtual mailbox). The mechanism is simple:

Your mail is addressed to — or forwarded to — the provider's address.
On receipt, each item is opened and scanned to a readable PDF.
The document appears in a web interface, notified by email.
You decide: archive, forward to the accountant, have the original re-shipped, or destroy it.

This model removes the dependency on one person who "does the mail" every morning. It shines above all for incoming registered mail, which carries a legal deadline and must be surfaced as a priority. For the detail of the inbound flow, see our article on digitizing inbound mail at a Belgian SME.

Outbound side: hybrid mail

The other half of outsourcing is hybrid mail (print & mail). Instead of printing an invoice or a formal notice yourself, you send the PDF to the provider — via software or an API — and it handles the rest: printing, folding, stamping, bpost drop-off.

This is especially efficient for:

Invoices and reminders sent in monthly batches.
Legal registered letters, with no trip to the post office.
One-off campaigns (customer letters, summons, notices).

For volume, our guide on bulk mailing with bpost for Belgian SMEs shows the savings. Full automation is covered in our solutions to automate office mail management.

The practical setup: address, bpost, onboarding

Outsourcing the inbound side means redirecting your mail. Three options:

Change the address with your correspondents: the cleanest, but slow (suppliers, banks, administrations).
bpost mail redirection: bpost offers a paid service that automatically forwards your mail to a new address for a set period. Note that bpost redirection does not cover every item (some administrative registered letters may be excluded) and has a limited, renewable duration.
A dedicated address from the start: ideal for a new company or a separate registered office.

For provider onboarding, plan for: a written mandate authorising it to receive your mail, the list of authorised people, sorting rules (who gets what), and the retention or destruction policy for originals.

Pros and cons versus in-house

Pros:

Zero paper handling, no dependency on a single employee.
Continuous processing even during leave or remote work.
Absorbs seasonal peaks without hiring.
Outbound sending without a trip to the post office.

Cons:

A recurring cost (but weigh it against the internal hours saved).
Dependency on a third party: secure it with a contract and SLA.
A trust question over confidential documents.
A 24 to 48 h scan delay with some providers (verify this).

The tipping point is almost always organisational: as soon as mail takes more than half a day a week or creates deadline risk, outsourcing becomes worthwhile.

GDPR and confidentiality with a third party

Entrusting your mail to a provider means entrusting it with personal data (invoices, medical letters, disputes, HR data). The provider then becomes a processor under the GDPR, and you remain the controller. Three non-negotiable requirements:

A data processing agreement (GDPR article 28) covering purposes, retention and security measures.
Hosting in Belgium or the EU: scans and the archive must not leave the European area without safeguards.
Strict access control: encryption, logging, least-privilege, secure destruction of originals.

This activity must appear in your data processing register. A serious provider supplies these documents without being asked.

What it costs

Rates depend on volume and scope:

Inbound (digital mailbox): often €50 to €200/month depending on the number of items scanned, sometimes with a per-item fee for re-shipping an original.
Outbound (hybrid mail): billed per item, typically €1 to €3 per simple letter (print + franking included), more for a registered letter.
Onboarding fees: one-off, to set up the address and mandate.

Compare that to the in-house cost: a scanner (€200 to €600), document management software (€20 to €80/month) and above all 10 to 20 hours monthly of handling. For a mid-sized SME, outsourcing often pays back within a few months.

Who should outsource

Outsourcing is not for everyone. It shines for:

Multi-site companies wanting a single mail address.
Remote teams or organisations with no permanent physical office.
Structures with seasonal peaks (tax season, deadlines, campaigns).
Companies whose executives are often on the move.

A micro-business receiving five items a month probably does not need a full provider. An SME receiving 80 items and sending 200 a month does.

Summary

Outsourcing mail processing is not just handing off a chore: it turns a manual, risky function into a remotely driven digital flow, inbound and outbound alike. It works when the provider is Belgian or European, contractually GDPR-compliant, and integrated with your tools. To assess a setup matched to your volume, contact the Bjet24 team.
