Reach thousands of customers in seconds.
In an age of overflowing email inboxes and algorithm-driven social feeds, SMS still cuts through. With a 98% open rate and most messages read within 3 minutes of delivery, bulk SMS remains one of the most powerful and cost-effective communication channels available to any business.
Whether you're sending a flash sale offer to 10,000 customers, an OTP to a new user, an appointment reminder to tomorrow's patients, or a delivery update to today's orders — SMS gets there instantly, every time, on every phone.
SMEdigital is a reliable bulk SMS service provider in Chennai offering a TRAI-compliant platform built for businesses of all sizes. Simple to use, competitively priced, and backed by real support — we make SMS marketing and communication effortless for Chennai's SMEs.
Monitor delivery and engagement live.
From promotional blasts to critical transactional alerts — we have every SMS use case covered with a reliable, compliant, and scalable platform.
Drive footfall, boost sales, and keep your customers engaged with targeted promotional SMS campaigns. Whether it's a festival offer, a flash sale, a new product launch, or a loyalty reward — promotional SMS puts your message directly in front of thousands of customers in seconds. Delivered to non-DND numbers between 9 AM and 9 PM as per TRAI guidelines, with real-time delivery reports so you always know your reach.
Transactional SMS is your lifeline for critical business communication. Order confirmations, payment receipts, shipping updates, booking confirmations, account alerts — these messages need to reach your customers instantly, every time, day or night. Our transactional SMS routes are prioritized for speed and reliability, with delivery to all numbers including DND subscribers, 24 hours a day, 7 days a week.
Security and trust start with a reliable OTP. Whether it's a login verification, a payment authentication, a new account signup, or a password reset — your OTP SMS needs to arrive in under 5 seconds. Our OTP SMS infrastructure is engineered for ultra-low latency, high concurrency, and 99.9% uptime — so your users never get stuck waiting for a code that doesn't arrive.
Reach customers who don't read texts — with voice SMS, your message is delivered as an automated phone call in Tamil, English, or Hindi. Perfect for political campaigns, event announcements, emergency alerts, and businesses targeting older demographics or low-literacy audiences. Voice SMS achieves outstanding reach in semi-urban and rural Tamil Nadu where voice communication is preferred over text.
With over 500 million WhatsApp users in India, bulk WhatsApp messaging lets you send rich, engaging content — images, PDFs, product catalogues, booking links — directly to your customers' most-used app. Unlike SMS, WhatsApp messages can include media, buttons, and quick replies. Our platform helps you send compliant WhatsApp campaigns through the official WhatsApp Business API, with delivery receipts and read confirmations.
Already have a website, app, or CRM? Our SMS API lets you integrate bulk SMS sending directly into your existing systems with just a few lines of code. Trigger OTPs at login, send order confirmations from your eCommerce platform, dispatch appointment reminders from your booking system, or automate any SMS workflow. RESTful API with comprehensive documentation, sandbox testing environment, and dedicated developer support.
