Start of the series: The Revolution Brought About by Digital Communication

Part 2: Paper-Based Communication: The Advantages of Traditional Media

The key to perfect communications lies in choosing between digital or paper or combining both, depending on the type of communication, target audience, message to be conveyed and other variables such as perceived cybersecurity and the digital divide.

In the field of Customer Communications Management (CCM), the choice between digital and paper channels is not a one-time decision but a configurable parameter within the organization’s overall communication strategy. Omnichannel orchestration platforms make it possible to automate this decision based on customer preferences, the type of communication, and regulatory requirements—without requiring each team to make it manually for every mailing.

Here is a comparative table that advises you to orchestrate this combination to meet the communication needs of your customers:

Feature Digital Communication (SMS, Email, WhatsApp) Paper Communication (Postal mailings)
Digital Divide Requires access to technology and digital literacy Universally accessible, without technological barriers
Sustainability Reduced carbon footprint Paper from responsibly managed forests reduces environmental impact
Speed Instant Days (depending on postal service)
Cost Inexpensive (per shipment) Higher (printing, handling, postage)
Traceability High (dispatch, delivery, content, identification…) Depending on the type of communication it can be higher or lower (a burofax will have high traceability while a regular marketing mailing will be low).
Interactivity High (clicks, direct responses, links) Low (one-way, except physical response)
Customization Massive and dynamic Massive
Cybersecurity Exposed to phishing, malware, data breaches (requires robust measures) Immune to cyber-attacks but does have risk of physical loss or theft
Duration Support Archiving or storage is not as straightforward Durable (physical, can be easily archived and consulted)
Perception Convenient, modern, fast Official, important, secure, personal
Ergonomics Reading Can be fatiguing, depends on the device Comfortable, less visual fatigue
Examples of use Alerts, reminders, promotions, online statements, communications with legal value, signatures, documentation… Contracts, policies, legal correspondence, annual reports, premium direct marketing…

Hybrid Communications Strategy: How to Combine Digital and Print Channels in Regulated Industries

A hybrid communications strategy is the operational model by which an organization assigns each type of communication with its customers to the most appropriate channel—digital or physical—based on the recipient’s profile, the legal nature of the message, applicable regulatory requirements, and customer experience objectives.

For comprehensive and effective communication, especially with banking and insurance clients, the key is a hybrid and adaptive strategy, where the choice of channel is based on the nature of the message and the preferences of the receiver:

  1. For Urgent, Operational and High Frequency Communications:
    • Fraud alerts, unexpected movements, card expirations, security notifications: SMS and WhatsApp are ideal for their immediacy and high opening rate.
    • Bank statements, policy summaries, transaction confirmations, personalized marketing communications and promotions: Email is the preferred channel due to its cost-effectiveness, ability to attach documents and possibility of including interactive links. Cybersecurity must be ensured with encryption and strong authentication.
  2. For communications with legal value such as contracts, general terms and conditions, as well as significant changes in products or services:
    • The physical channel is the traditional one for this type of communications since it provides maximum reliability and eliminates the digital divide. However, digital communications also provide legal certainty, immediacy and is the channel of choice for many users today.
  3. For premium direct marketing actions or welcome/loyalty communications:
    • A well-designed and personalized letter can generate an emotional impact and a perception of value superior to an email, contributing to differentiation. It can also be combined with digital marketing strategies and thus enhance the impact and therefore the desired result/conversion.
  4. Additional Considerations:
    • Digital Divide and Aging Population: Always offering the option of receiving communications on paper is crucial to leave no one behind. For the older or less digitized segment of the population, paper is the preferred and often the only accessible and trusted channel.
    • Customer Preferences: Whenever possible, allow the customer to choose their preferred channel for each type of communication. A robust preference management system increases satisfaction and engagement.
    • Cybersecurity: For digital communications, the customer should be educated about the risks of phishing and the importance of verifying the source. For paper, confidentiality must be ensured in the printing and mailing process.

By implementing this dual strategy, your company will not only optimize costs and efficiency, but also build stronger and more reliable relationships with your customers, adapting to their needs and preferences in a constantly evolving communication environment.

Keep close track of every interaction and document issued, simplifying internal audits with tools that centralize and secure your process history through our regulatory compliance solutions.

In the following table, we summarize the keys to the choice of channel according to the type of specific communication to be carried out:

Type of Communication Preferred Channel Key Justification
Urgent/Operational Digital (SMS, WhatsApp, Email) Instantaneousness, agility, real-time alerts, confirmations.
Legal/Contractual Paper (Letter, Burofax)
Digital (SMS, WhatsApp, Email)
Formality, probative value.
Marketing/Promotional Digital (SMS, Email, WhatsApp) Cost efficiency, mass customization, traceability, interactivity.
Informative (Detailed) Paper (Reports, extracts) or Digital (Email with PDF) Ergonomics of reading (paper), accessibility (paper), convenience (digital).
Inclusion/Digital Gap Paper Universal accessibility, overcomes technological barriers for older or less digitized people.
Loyalty/Premium Paper (Personalized letter) Emotional impact, differentiation, sense of belonging.
Security (Perception) Paper and Digital Confidentiality in printing and shipping. Robust measures to guarantee digital security.

That concludes our series on print and digital communications. We hope you enjoyed it and that it gave you a good overview.

Designing a hybrid communications strategy does not require making manual decisions on a channel-by-channel basis: Customer Communications Management (CCM) platforms Customer Communications Management (CCM) such as Communicalia allow you to configure orchestration rules that automatically assign the optimal channel based on the message type, the recipient’s profile, and applicable regulatory requirements. At MailComms Group, we support companies in the banking, insurance, and utilities sectors in implementing this model, integrating both certified digital channels (certified email, certified SMS, certified WhatsApp) and physical communications into a unified strategy with full legal traceability.

Frequently Asked Questions

What is a hybrid communications strategy, and when is it necessary?

A hybrid communications strategy is a model in which an organization combines digital channels (email, SMS, WhatsApp) and physical channels (mail, certified fax), assigning each type of communication to the most appropriate channel based on the nature of the message, the recipient’s profile, legal requirements, and customer experience objectives. It is particularly necessary in regulated sectors such as banking, insurance, and utilities, where urgent communications (which require digital immediacy) coexist with legal communications (which may require physical proof of delivery or digital certification).

When is it mandatory to use paper in communications with customers?

There is no general requirement to use paper, but there are situations in which it is the safest or required option: when the recipient does not have access to digital channels (digital divide), when sector-specific regulations require a physical medium (certain financial or insurance contracts under specific circumstances), and when universal accessibility must be ensured in accordance with Law 11/2023 and Directive (EU) 2019/882. In all other cases, certified digital communication offers the same legal guarantees as paper, but with greater efficiency.

What are the advantages of certified email over conventional email for legal communications?

Certified email, unlike conventional email, generates electronic evidence with probative value: it certifies the sending, receipt, content, and identity of the sender with full legal validity under eIDAS. This provides the same level of assurance as a certified mail (burofax) for communications requiring legal certainty, with the added advantages of immediacy, lower cost, and complete digital traceability.

How can a company automate the decision between digital and paper channels?

Through Customer Communications Management (CCM) platforms that incorporate configurable orchestration rules. These rules enable the automatic assignment of the optimal channel based on parameters such as the customer’s stated preferences, the type of communication, the regulatory sector, the recipient’s age or digital profile, and applicable regulatory requirements. The result is a consistent and scalable hybrid strategy that requires no manual intervention for each message.

What is the difference between omnichannel communication and multichannel communication?

Multichannel communication uses multiple channels independently: each operates in silos without coordination among them. Omnichannel communication integrates all channels into a unified experience with cross-channel traceability: the customer can start a conversation via email and continue it by mail or text message without losing the thread, and the organization has a complete view of the entire interaction. For regulated industries, omnichannel communication adds the dimension of regulatory compliance integrated across all channels.
