Create short, personalised SMS campaigns for offers, reminders, follow-ups and announcements - with built-in UK GDPR compliance checking, character counting and a send-cost calculator so there are no surprises.
UK businesses that run SMS campaigns without understanding PECR and GDPR risk ICO fines. And those that don't track character counts end up paying for 2-credit messages when they only needed 1.
ClientRoots's SMS Builder checks compliance as you type, shows your credit cost in real time, and generates personalisation tokens automatically - so your campaign is compliant, cost-efficient and effective before you send a single message.
Every feature is designed to help UK businesses run compliant, effective SMS campaigns without needing a specialist.
Watch the character count and credit cost update in real time as you type. The counter highlights when you're approaching the 160-character limit and shows when a second credit will be charged.
Automatically flags missing opt-out language, identifies restricted content and confirms whether your message meets ICO SMS marketing guidelines before you finalise it.

ClientRoots creates the SMS copy for you - the actual sending is done via your own Twilio or Textlink account, or through your preferred SMS provider. The tool generates the message, calculates the cost and checks compliance. You copy the output into your sender platform. API integration for direct send is available on Agency plan.
Under PECR (Privacy and Electronic Communications Regulations), you can only send marketing SMS to individuals who have explicitly opted in to receive messages from you. Every message must include a free opt-out mechanism ("Reply STOP"). ClientRoots flags missing opt-out language and highlights any content that may breach ICO guidelines.
A standard SMS is 160 characters using the GSM-7 character set. If you use special characters or emojis, the limit drops to 70 characters per credit (using Unicode encoding). ClientRoots's character counter tracks both and alerts you before you accidentally trigger a second credit charge.
The Campaign Calendar (Business plan and above) lets you plan and schedule when campaigns should go out. Actual scheduled sending depends on your SMS provider's API capabilities. The calendar gives you a visual plan of upcoming campaigns and sends a reminder notification when a campaign is due.
