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
If you write or edit patient messages
The NHS Content guide has additional guidance on tone of voice, formatting and writing for different channels, with examples of NHS App messages, texts, emails and letters.
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.
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.
The time that you send your message can also affect read rates and engagement. You should consider the needs of your users and the type of message you are sending before you choose a time.
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.
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
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
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.
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.
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
