eIDAS defines Electronic Registered Delivery Services (ERDS) as the service that makes it possible to transmit data between third parties with evidence of handling, including proof of sending and receiving, with protection against loss, theft, damage or any unauthorized alterations.
For years, people in the regulated industries thought that the sole purpose of Electronic Registered Delivery was to reduce the risk of litigation, and it only had to be activated in cases where there was a need to prove that contents had been sent, delivered and made available to the addressee.
However, with the advent of eIDAS 2.0 this approach becomes too restrictive, not because the evidence function becomes less important but because legal proof is no longer the only factor in play. Nowadays, registered delivery has become a strategic touchpoint in the regulated customer journey: one where trust is built, and which affects the brand’s image and defines the quality of experience at crucial times (signing and renewal of contracts, unilateral changes to contract terms, compliance communications and notifications with financial or legal impact).
The European context
The European context is pushing in this direction. The European Commission continues to view eIDAS as a tool for facilitating secure digital transactions and a means for increasing trust in cross-border electronic interactions. At the same time, the uptake of public digital services is growing: in 2024, 70% of EU citizens (age 16–74) had used public authority sites or apps in the previous 12 months, a sign of rising expectation of reliable “official” digital interactions.
In this article, we look at the issue from a different perspective: with eIDAS 2.0, Electronic Registered Delivery ceases being an isolated component and becomes part of an infrastructural layer of digital trust that combines identity, delivery, signature and archiving.
Beyond evidence: why registered delivery becomes relationship
Legal evidence continues to be fundamental. In its ERDS specifications, the ETSI (European Telecommunications Standards Institute) explicitly sets out the events-based logic of digital trust services in the regulated industries:
- the service tracks the submission of the message (i.e. it provides a formal, verifiable record of the moment when the sender submits the message to the service),
- it produces evidence (attestations, structured electronic evidence),
- it tracks consignment to the recipient (the service verifiably records the moment when the message is made accessible to the recipient, regardless of whether they have already opened or read it),
- it can return attestations to the sender (dispatch to the sender of formal electronic proof certifying the occurrence of the event within the delivery process).
This succession of causal relationships is necessary to support a robust chain of evidence. What emerges, with eIDAS 2.0 and the evolution of the regulated customer journey, is the “experiential” role of the entire interaction. The user doesn’t see the ETSI standard or regulatory definitions. What they do perceive, often implicitly, are the levels of authenticity, traceability, reliability and undeniability (meaning the impossibility of claiming that the action performed did not take place) of the various steps.
Registered delivery in the regulated industries: the critical intersection between compliance and relationship
In industries with high regulatory exposure, qualitative aspects are a central factor in the relationship with users and customers. Notices, updates, amendments, expiries, claims, requests for documentation, implementing measures: in every one of these cases, registered delivery is a critical point where trust is either generated or lost. And here, typically, a mismatch emerges: over time, many organizations have built systems designed to “pass an audit” and not to “support a relationship”.
eIDAS 2.0 envisages a model in which there is no conflict between compliance and customer experience. In regulated communications, an experience that lacks clarity or makes too many demands on the user doesn’t improve but rather often weakens the legal safeguards, because it leads to errors, escalation to the contact center, complaints and operating frictions.
Inbox neutrality and interoperability: trust can’t depend on a single inbox
In the physical world, a notification has value because it arrives at the place where the user can receive it, not because the user accepts communication via a single proprietary channel. In the digital world, many historic registered delivery service systems have, either explicitly or implicitly, led to a form of lock-in: one channel, one inbox, one format, one perimeter.
With the advent of eIDAS 2.0, this approach implies a strategic risk that must not now be underestimated. The real value of registered delivery increases when it can take place in an interoperable way, reducing frictions between domains, countries, providers and enterprise systems. The Commission and the eDelivery ecosystem have focused strongly on the issue of conformance and interoperability, and as a result have linked ERDSs to ETSI requirements and standards and evidence exchange mechanisms.
Inbox neutrality as a pragmatic principle
It thus becomes clear that Inbox neutrality is first and foremost a pragmatic principle: it must be possible for regulated communications to be delivered to the user in the way most appropriate to the latter’s digital context, without any change in the associated evidence and integrity. This is a real prerequisite for adoption: if the user has the impression that regulated communication is linked to a specific environment or a separate channel, they will tend to postpone, ignore or delegate its implementation. If, on the other hand, they see it as natural and reliable, they will opt to adopt it.
Looking at the broader context, we can see the emergence of a systemic trend: the use of official digital services is on the increase, but rates vary a great deal between countries. In 2024, for example, use of e-government varied hugely between Member States, with percentages ranging from over 95% to very low values. For a business working on more than one market, this means there’s no such thing as the average European user: levels of digital maturity and expectations vary widely. It’s here that inbox neutrality and interoperability become the critical factors for managing this heterogeneity without sacrificing legal certainty.
Branding and personalization in regulated communications
One of the most common misconceptions is that branding and personalization have nothing to do with regulated communications. In reality, even in a regulated touchpoint branding is first and foremost a matter of ensuring recognition and reducing ambiguity.
When a customer receives a communication with potential contractual or financial consequences, the first question they ask themselves regards its authenticity. If the company doesn’t guarantee consistent management of visual and textual signs (sender, domain, naming, language and structure), they open the way to three risks: phishing and social engineering, doubts about authenticity, and an increase in calls to verify the communication. All three produce a cost and cause erosion of trust.
Personalization means contextualization
In an age where the eIDAS aims to create trust in electronic interactions, the presentation of the communication – how the contents reach and are perceived by the user – is part and parcel of the “psychological contract” between the organization and the addressee. What’s more, personalization isn’t only linked to marketing practices: it means above all contextualization, meaning placing the communication within the specific framework of the ongoing relationship, and connecting it to the contract, transaction or event to which it refers.
In regulated processes, contextualization reduces errors and complaints because it helps the recipient to understand what they are receiving and why, which actions are required and any deadlines for them.
All this must happen without undermining the evidence: the customer experience mustn’t interfere with the proof – in other words, it mustn’t detract from the integrity, traceability and legal validity of the evidence generated by the process – but nor must the need for proof make the customer experience burdensome or unpleasant. The right architectural design will square the circle between these two needs.
ERDS as a bridge between identity, delivery and archiving
In practice, registered delivery really becomes meaningful when it’s verifiably connected to the identity of the party concerned (i.e. the person who requested, accepted or read the communication), the specific contents sent (i.e. the document or deed delivered) and a specific archiving action (how the evidence is preserved over time). With eIDAS 2.0 and the evolution of the wallet, it’s reasonable to expect an increase in the interdependency of these factors.
The limitations of isolated services: when integration is not enough
Many organizations already integrate the component parts of their digital trust processes. However integration, especially in enterprise architectures, isn’t the same as orchestration.
An ERDS integrated with a CRM or documentation system is able to function in stable conditions. The problem emerges when the channels, volumes, requirements, geographical localizations or providers change.
The typical limitations of isolated services are differences in evidence across channels, difficulty in correlating events along the journey, complex management of exceptions, duplication of audit logics and dispersal of responsibility across vendors. The overall result is a weakening of the organization’s ability to govern trust as an asset.
A platform-based approach, on the other hand, provides a model in which trust is governed as infrastructure: coherent polices, standardized evidence, correlation of events, centralized auditability, and the capability to adapt to new requirements without having to re-engineer workflows every time.
This is where value becomes tangible, since entropy is reduced. And, in regulated processes, reducing entropy means a decrease in operating criticalities, legal risk and operating costs.
Every regulated communication involves trust
The growing uptake of official digital services in Europe implies a profound cultural change: while the public and businesses become used to managing interactions of high formal importance online, the eIDAS consolidates the trust and security framework for cross-border electronic transactions. In this context, Electronic Registered Delivery is transformed from the fulfillment of a compliance requirement to the point at which an organization provides tangible proof of its digital trustworthiness.
The strategic issue relates not to the usefulness of ERDS as such, but rather to the ability to manage it as a central part of the regulated relationship, in which trust is both a legal requirement and the outcome of the user’s lived experience. When compliance and customer experience are designed as complementary experiences, regulated communication stops becoming an unavoidable cost and is transformed into a tool for operational improvements: it reduces ambiguity and complaints, improves the management of exceptions, takes the strain off help centers and makes processes more predictable.
