Business SMS Messaging in the UK: Consent, Localisation and Campaign Planning
A practical guide for CRM, marketing and product teams using SMS for verification, service notifications, customer communication and consent-based campaigns in the UK.
Planning Business SMS Communication for UK Audiences
Business SMS communication in the UK should be planned around a clear customer purpose, an appropriate audience and a well-defined action.
Before sending messages, teams should review five areas:
- customer consent and the reason for the communication;
- message type: verification, service notification, transaction update or promotional communication;
- sender identification and recognisable brand context;
- relevance, timing and message frequency;
- the landing page or customer journey that follows the SMS.
For regulated industries, including iGaming, financial services and healthcare, internal compliance review should be part of the campaign workflow. Marketing messages should be sent only where the business has an appropriate basis to contact the recipient.
