About this guidance

This is for anyone involved in planning or sending patient messages, including product teams, programme leads, operational staff, service managers and content designers.

This page explains:

  • when and how to message patients and the public
  • the benefits of digital-first channels
  • what governance to follow to protect patients and their data
  • how to use NHS Notify

This guidance is evidence-based and was developed with clinical safety, governance and delivery teams across NHS England. It combines established NHS standards with user research and aligns with existing policy. It was created to help teams send clear, safe and effective messages to those using NHS services.

Messaging infrastructure varies across the NHS. Some teams send messages directly through the national messaging service NHS Notify, while others use third party messaging providers. However you message patients, you should aim to apply these best practice principles.


Writing or editing patient messages

Patients are less likely to understand a message if it contains clinical terminology, acronyms, and internal NHS language. 

Duplicate messages, unclear appointment information, inconsistent reminder schedules, and varying options for booking, rescheduling, or cancelling appointments also create confusion. 

These inconsistencies can contribute to poor patient experience, increased Did Not Attend (DNA) rates, and inefficient administrative processes.  

The Writing NHS messages page has additional guidance on tone of voice, formatting and writing for different channels, with examples of NHS App messages, texts, emails and letters. 


Message channels

Using the right channel to send your message can have a big impact on its effectiveness and patient health outcomes.

It is NHS policy that providers proactively offer NHS App-first communications to patients, whenever possible. Most messaging services allow you to create a routing plan with fallback options to alternative channels such as text message, email or letter.

Check spelling and grammar.

If you can, check new templates or review existing templates before you send them.

Send test messages to yourself or a small group to test comprehension.

NHS App messages

The NHS App has a secure inbox that allows patients to receive messages from health and care services, such as their GP surgery. Using the NHS App to deliver your messages is a convenient and cost-effective way of managing communications between your service or national programme and your users. NHS commissioned services can use NHS App messaging for free. For the channel to be most effective, users need to have push notifications turned on.

Benefits of NHS App messages:

  • free, secure and trusted by patients
  • safely link out to documents and letters
  • sent using NHS number, ensuring the message reaches the correct person
  • can send a variety of message types such as batch invitations, appointment reminders and booking links
  • supported by a nation-wide mixed media campaign encouraging patients to download the NHS App and turn on notifications
  • track delivery and read status to check if your message has been received

It is important that NHS App users switch on push notifications so that they:

  • will be alerted when they receive messages related to their care
  • get better health outcomes by accessing messages about their health faster and more securely
  • support the NHS by messages going through a cost effective, reliable and secure communications channel

Text messages

Text messages, also called SMS messages, are a reliable fallback channel when NHS App messages are not read, for example, when patients do not have the NHS App installed or have not turned on notifications.

Benefits of text messages include:

  • they are cost-effective when compared with sending letters
  • widely accepted as an NHS message channel by most patients

However, text messages do have some drawbacks when compared to NHS App messages.

These include:

  • lower trust – evidence shows patients are reluctant to click on links in text messages due to phishing concerns
  • no read confirmation – unlike NHS App messages, it is not possible to confirm if a text message has been opened or read
  • safeguarding – text messages can be read by anyone with access to the recipient’s phone, so should not contain sensitive information
  • cost – if a text message is longer than 160 characters (including spaces), it will be charged as more than one message

Emails

Email is an effective digital channel and is free at the point of use. Some national programmes have found that users prefer email when a message is long, complex or contains sensitive personal information such as test results.

However, there are limitations when using email to contact patients and these should also be considered:

  • lower trust – because email is often used for phishing, some users may distrust links or ignore messages
  • safeguarding – emails can be read by anyone with access to the recipient’s phone or computer and email account
  • unreliable delivery and visibility – emails may be filtered into spam or low-priority folders, or simply not checked regularly, so they may not reach the user at the right time
Paper letters

Letters are a reliable fallback channel and offer several benefits to patients, particularly where digital access is limited. These include:

  • accessibility – availability in large print, braille or translations
  • sensitivity – some national programmes found users preferred letters when communicating sensitive information such as test results
  • clear messaging – some national programmes found letters were better for explaining complex booking or screening procedures

However, letters do have limitations when compared to digital alternatives. These include:

  • delivery – letters cannot support time-critical updates as delivery times vary and may be affected by postal delays
  • digital accessibility – letters cannot be used with assistive technology such as screen readers
  • connectivity – patients cannot click through to digital services, meaning letters can create extra steps for booking, checking results or updating details
  • environmental impact – printing and postage create a significantly higher carbon footprint compared with digital channels
  • safeguarding – letters can be read by individuals other than the intended recipient
  • cost – printing, postage and administrative handling make letters more expensive than digital channels

When to send your message

When you send your message can impact how quickly the recipient reads or responds to a request.

Some message sending services will only deliver messages between certain hours and days of the week. For example, NHS Notify will send messages to the NHS App at any time, but will only send text messages between 8am and 6pm on weekdays.

Put the needs of the patient first when deciding when to send a message. For example, avoid sending non-urgent messages at weekends, in the evenings or very early in the morning unless there is a clear user need. For urgent or time critical messages, consider whether delaying the message could increase clinical risk. Ensure there is an appropriate escalation or fallback route in place.

Think about what impact your message will have on the person receiving it. Patients are less likely to respond to a message if they are irritated or annoyed by it. Similarly, some may become anxious if they are unable to respond immediately.

When choosing when to send your message consider:

  • the impact multiple messages in one delivery or in quick succession could have on the patient

  • if you are expecting a response from the patient and within what timeframe

  • the time of day you send a message

  • type of message you are sending and if it is urgent or non-urgent, expected or unexpected

  • time you leave between the initial message and a reminder, so you are not overloading the patient with information

  • channel you have chosen to send your message and your fallback strategy, for example App first, then text and then letter

  • overlap with other NHS services such as national vaccination campaigns

  • patients you cannot message


Governance and patient safety

In the NHS, governance refers to the systems, processes, and leadership structures that ensure health services are safe, effective and accountable. When messaging patients you have a legal obligation to follow specific laws, regulations and policies to protect patient data and ensure their clinical safety.

Before you message patients or service users you should check that you are following your organisation’s local procedures, and ask for help if you are unsure.

The following sections explain more about the teams overseeing governance and patient safety obligations within the NHS.

Information governance

Patient health data is protected by law. The law allows confidential patient information to be shared between those providing care to patients, and ensures that patient confidentiality is protected at all times. It protects patient confidentiality when the data about them is used for purposes other than direct care.

NHS England offers information governance (IG) support and guidance to ensure that all messages sent to patients meet NHS service standards. However, it is your responsibility to ensure these standards are met.

If you are unsure you should consult with your Data Protection Officer (DPO), IG team or senior staff before sending any messages. If you use NHS Notify as your messaging service provider, their team will discuss with you the steps to send your first message, including any IG requirements.

To recap:

  • NHS England offers IG advice to message senders
  • it is your responsibility to ensure your message content is compliant with NHS governance
  • consult with your DPO, IG team or senior staff before sending any messages
  • check your organisation’s local procedures for messaging and ask for help if anything is still unclear
  • NHS England has published detailed guidance on messaging patients, security measures and how to practically meet legal requirements for protecting patient data.

Read NHS England’s information governance guidance.

If you do not have someone you can ask about IG requirements for messaging, you can submit a query to NHS England's IG team. Your message will go to a shared mailbox. 

Submit a query to NHS England's IG team.

Clinical safety

Clinical Safety Officers (CSOs) ensure that digital systems and services do not introduce avoidable clinical risk. They do this by following NHS safety standards.

These include:

  • identifying and assessing clinical risk to patients
  • documenting and managing those risks
  • providing clinical safety advice
  • maintaining assurance documentation such as hazard logs

Messages relating to patient care or clinical information must meet the same safety standards as other parts of the service. If your message includes clinical or personal information, confirm with your Clinical Safety Officer (CSO) that it’s appropriate for the chosen channel and follows your risk-assessment process.

If you use NHS Notify as your messaging service provider, your CSO may need to complete a Supplier Conformance Assessment List (SCAL) as part of the clinical safety and governance checks.

Cyber security

You should prioritise digital security when messaging patients. If you have your own cyber security team they will be responsible for testing the resilience of your service. If you use NHS Notify as your messaging service provider you should be aware that it is not responsible for approving the content of the messages it sends.

Legal

Every message must have a legal basis to be sent. It is your responsibility to justify that the message is tied to someone’s care or the functioning of the health service. Messages need to balance an individual’s privacy with necessary healthcare communication. If you are unsure about your obligations, you should consult with your legal representative.

Read more about NHS Notify’s acceptable use policy.

Using Artificial Intelligence (AI)

Assess whether your proposed processing is likely to result in a high risk to individuals and complete a local Data Protection Impact Assessment (DPIA) where required. You should follow your local Acceptable Use Policy (AUP).

Using NHS Notify

Not all teams are able to use NHS England’s national messaging service, NHS Notify. Some teams use commercial messaging platforms to communicate directly with patients and service users.

However, it is NHS policy that teams endeavour to use NHS Notify whenever possible.

NHS Notify allows you to:

  • tailor your messages to specific groups of patients or service users
  • select a channel routing plan that includes NHS App, email, text message and letter
  • choose when and how messages are sent
  • reduce costs, with competitive rates for SMS and no charge for NHS App messages
  • send letters to patients and members of the public in additional languages

Steps to using NHS Notify





During the NHS Notify registration process you will be asked about:

  • your organisation or service
  • your use case
  • any previous messaging experience
  • how you want to pay
  • how you plan to integrate with the service
  • agreeing to NHS Notify’s terms and conditions

Managing message templates

Messaging providers often ask organisations to create reusable message templates for different channels and message types. 

This means that over time your template library will grow as new templates are added. If it is not managed properly, it can become difficult to find the right template and increase the risk of sending outdated or incorrect messages. 

How to manage your template library

Before creating a new template, check whether there is already one that can be used or updated. 

 Creating fewer templates makes the library easier to manage. It also means that changes, such as updating a web link or clinic opening times, only need to be made once. 

Use a naming convention and version control

Give templates clear, consistent names so staff can find them easily. 

Use version numbers or dates to show which template is the most recent.

Archive old templates 

Regularly archive templates that are out of date or no longer needed.

Organise templates into folders 

If your system allows it, group related templates into folders. For example, you could have folders for appointments, waiting lists or service updates.

Give ownership to a member of staff 

Assign responsibility for the template library to a named member of staff or team. They can review templates, keep content up to date and make sure standards are followed.

Benefits of a well-managed template library 

A well-managed template library: 

  • reduces the risk of outdated or incorrect messages being sent 
  • saves time when staff need to find a template 
  • makes updates quicker and easier 
  • helps keep messages consistent in quality and tone of voice 
  • reduces the amount of training staff need to use the system

Changes to templates containing clinical information, instructions or calls to action should be subject to appropriate review and approval before publication.

Naming services in patient communications

Those receiving the message should be able to quickly understand who is contacting them and why. Research found that many patients do not recognise NHS organisational structures, trust names, department names, acronyms, or internal service terminology. Using clear, patient-friendly service names helps them identify the right service, trust the message, and take action.  

Use a name patients recognise 

Choose service names based on the words patients use and understand, not the words used internally by staff or systems. Service names should be informed by user research and describe the service in plain language.

Good examples include: 

Health Visiting Service 

School Nursing Service 

Diabetes Clinic 

Children's Speech and Language Therapy 

Community Mental Health Service 

Less effective examples include: 

CYP Community Integrated Care Pathway 

PCN Enhanced Access Service 

Community Health and Care Directorate 

Division of Integrated Children's Services

Keep names short and clear 

Long names make messages harder to understand and take up valuable space in text and NHS App messages. NHS guidance recommends that names are clear, logical, descriptive and concise. Avoid acronyms and abbreviations. 

Use service names, not programme or team names 

Internal team names often have little meaning to patients. For example, use “School Nursing Service” instead of “Public Health Nursing Team”, or “Physiotherapy Service” instead of “MSK Transformation Programme”. 

Some services have official names that must be used in specific contexts. When this happens, consider adding a patient-friendly description. For example “Community Integrated Care Team (your district nursing service)” or “NHS Healthy Child Programme (health visiting and school nursing)”. 

Be consistent 

Patients become confused when the same service is described differently across messages, appointment letters, websites, and the NHS App. 

Create a single agreed service name and use it consistently.

Test names with patients 

Names should be tested with patients and based on evidence, not assumptions. Government and NHS guidance both recommend engaging users and patients to check whether names are clear, understandable, and recogniseable. 

Checklist 

Before sending a message ask: 

  • Is this the name patients are most likely to recognise? 
  • Have we avoided acronyms and jargon? 
  • Is the service name short and clear? 
  • Would a patient know who is contacting them? 
  • Is the name used consistently across all channels? 
  • Have we tested the name with patients or used existing research?

Test your messages

It is important to test your messages before you send them.  

Research has revealed that some messages are poorly formatted or unclear. This can lead to frustration, anxiety and failure to complete a task that could impact their health.   

Follow some basic rules to ensure your messages are read and understood. 

  • check spelling and grammar 
  • send test messages to yourself or a small group to test message comprehension and how it would look as a text, email or App message 
  • review existing templates and make sure they follow guidance on writing NHS messages

In addition, consider the following best practice: 

  • make it clear who the message is for, especially if you are writing to someone with a carer 
  • check your sender name makes it clear who the message is from and any email subject lines are short and describe the contents of the email or the action required, for example “Your appointment details” or “Booking an NHS blood test” 
  • use plain simple English 
  • try to only include one action for the recipient to take 
  • put all the information the patient needs to complete the task first 
  • only include extra information if it helps the recipient complete the task  
  • never ask for personal information

Accessible and inclusive messages

Digital-first does not mean digital-only. Teams are encouraged to always consider accessibility and inclusion when communicating with patients.

Your messaging service may allow you to set routing plans. This makes it more likely that messages will reach their intended recipient through a channel they will engage with. For example, patients without the NHS App or an email address can still receive healthcare messages by text message or letter.

Find NHS guidance on creating accessible content for digital services. 


Case studies and performance data

Use this section to help support your decision to follow an NHS App-first approach to your digital messaging strategy.

Case studies

Performance data

61%

of delivered NHS App messages lead to patient action

During the Autumn/Winter 2025 vaccination campaign, 61% of patients who received an NHS App message responded to the request. This compares with 46% for text messages and 42% for letters, thereby helping patients access vaccinations faster while reducing reliance on higher-cost, less efficient communication methods for the NHS

75%

of messages read in the NHS App resulted in users completing a task

Patients asked to complete a digital health assessment or follow-up action were more likely to respond after reading a message in the NHS App. A national programme found that 75% of users completed the requested action, compared with 30% for other communication channels — likely because users could respond immediately while already logged into the app

52%

of NHS App messages read within 72 hours

Read rates from a national screening programme and user research found patients reading messages within 72 hours were more likely to respond to calls to action

1.2m

patients received a vaccination after being invited through the NHS App

During the Autumn/Winter 2025 vaccination campaign, more patients received their vaccination after an App invitation than after a letter invitation (842,191). This means patients are accessing vaccinations faster while reducing reliance on higher-cost postal communications
