Designing Public Service Communication: A UX Strategy for a Digital Mailbox MVP

Led UX research for a government digital mailbox MVP, identifying usability barriers, accessibility issues, and user needs to shape a scalable,  public service platform.

The Scottish Government sought to digitise postal communications to create a secure, efficient, and user-friendly government messaging system. As the UX Research Lead, I conducted strategic user research to define the optimal experience for a digital mailbox that integrates identity verification, secure messaging, and service accessibility.​

 

Through extensive research with citizens, case managers, and advisors, we identified pain points, inefficiencies, and opportunities for innovation, shaping an MVP that directly impacts public sector efficiency and user trust.

Responsibilities

  • Lead UX Researcher – Driving user insights to inform digital transformation strategy.

  • Cross-functional Collaboration – Working with government stakeholders, policy teams, and service designers.

Hypothesis

  • A digital mailbox will streamline communication and reduce admin workload.

  • Users will prefer a secure, centralised system over postal services.

  • Real-time updates will enhance trust and engagement with public services.

Methodology

  • 10 SME Interviews: Engaged with government experts and service providers to align policy, security, and digital transformation goals.

  • 6 Usability Tests & 1:1 Interviews: Tested the digital mailbox prototype with citizens, identifying usability gaps and accessibility needs.

  • 2 Focus Groups: Collaborated with case managers and client advisors to evaluate internal process challenges.

Goals

  1. Identify key usability barriers and challenges in the MVP.

  2. Validate user expectations for a digital communication.

  3. Ensure seamless integration with government services.

  4. Provide strategic recommendations for future iterations.

Strategic Approach:

Accessibility & Digital Literacy

Designed an inclusive UX experience to support users of all skill levels. Focused on mobile-first interactions as most users preferred tablets. Simplified navigation, text hierarchy, and input processes for clarity.

Streamlining Supporting Information

Identified delays caused by reliance on GP documentation. Proposed direct GP-to-mailbox document submissions to improve efficiency. Simplified guidance on acceptable documents to reduce confusion.

Improving Communication & Notifications

Proposed real-time notifications to reduce uncertainty and user frustration. Created clear, actionable prompts to help users understand next steps.

Trust & Security in Digital Services

Addressed user concerns on data privacy and security. Ensured users had control over their submitted documents and information.

Key Findings:

01.

Digital Trust Concerned about data security and privacy risks.

02.

Submission Delays: GP documents caused long processing times.

03.

Navigation Issues: Struggles with layout and key tasks.

04.

Status Tracking: Real-time updates instead of manual follow-ups.

Problem Statement

How can the Scottish Government modernise communication, ensuring secure, accessible, and efficient interactions while improving transparency and reducing administrative burden?

UX Research Insights:

01

Service Accessibility

Users wanted more options for accessing services beyond digital platforms.

Offline support options were necessary for those without internet access.

Some users needed simplified authentication for easier logins.

02

Task Completion Barriers

Users often abandoned forms due to unclear instructions.

Error messages were not helpful in guiding next steps.

Users needed clearer progress indicators to track completion.

03

Information Overload

Too much content
on screens overwhelmed users during applications.

Users skipped important steps when faced with excessive information.

A streamlined layout helped reduce confusion and errors.

04

Support System Gaps

Users lacked easy ways to contact support when facing issues.

Live chat or call-back options were preferred for quick help.

Self-service FAQs needed clearer language and structure.

05

Personalisation Preferences

Users wanted settings to adjust notifications based on urgency.

Customisable dashboards helped users prioritise important messages.

Flexible display options improved readability for different user needs.

User Needs

  1. A secure, easy-to-use government portal for managing documents.
