KDJ Tools – Bulk SMS Sender

Send personalized bulk SMS messages via httpSMS

Developed by KDJ Lanka (Pvt) Ltd, this lightweight browser extension simplifies your communication workflow by turning Chrome's side panel into a bulk SMS studio. Effortlessly import your contact list from a CSV, personalize every message with each recipient's name, and dispatch large volumes of messages in a safe, paced, and trackable way—delivering reliable SMS campaigns in any sending session without risking duplicate, lost, or overlapping messages. KDJ Tools – Bulk SMS Sender helps you send personalized bulk SMS messages directly inside your browser. Key features: - Personalized message templates using the {{name}} placeholder for every recipient - CSV contact import with automatic duplicate handling and phone (E.164) validation - Adjustable per-message send delay to pace sending safely and avoid rate limits - Full campaign controls: pause, resume, and cancel - Live progress tracking across pending, submitted, sent, delivered, and failed states - Automatic retries on rate limits and network errors with increasing backoff intervals - Schedule messages up to 20 days in advance — accepted sends go out even if Chrome closes - Automatic recovery of interrupted campaigns after a browser restart Your API key, contact names, and phone numbers are stored only in this browser's local storage and are transmitted solely to the httpSMS service you configure to send your messages; the extension developer does not receive, collect, or store your message content or contact details. No advertisements, no tracking, no analytics.
