DLT Compliance Built into Every Campaign
Every message sent through KAPSYSTEM follows TRAI's DLT rules. Your business entity, headers and templates are registered on an operator DLT portal, each template is filed under the right category (promotional, transactional, service implicit or service explicit), and every link in a template is whitelisted before sending. Promotional campaigns are scrubbed against the DND register, sent only between 9 AM and 9 PM and include opt-out handling. Our team reviews every template before submission to avoid rejections.
