Syncodian Technologies Bulk SMS & Voice Call
Bulk SMS and voice call marketing
Reach thousands of customers on the channels they actually check — SMS, voice and WhatsApp — with the compliance, routing and delivery reporting handled by us. You bring the message and the audience; we make sure it arrives, legally.
What we run
Bulk messaging in India fails for a predictable reason: compliance. Unregistered senders get blocked at the operator level, templates that do not match their DLT registration never deliver, and providers who promise shortcuts around DND rules put your business at risk of penalties. We run messaging the compliant way — registration, templates, opt-in and the 9am–9pm promotional window — because messages that deliver beat messages that bounce.
Promotional bulk SMS
Offer, announcement and festival campaigns to opted-in audiences via web panel or API — sent within TRAI's permitted promotional window.
Transactional and OTP SMS
OTPs, order confirmations, delivery alerts and payment reminders on priority routes, deliverable around the clock with delivery reports.
Voice broadcasting
Pre-recorded voice messages auto-dialled to large lists — regional-language audio, scheduling, retries and press-1 responses for surveys and lead capture.
WhatsApp Business API
Template-based broadcasts with images, PDFs and buttons, chatbot auto-replies and verified business profiles — two-way conversations at scale.
DLT registration and compliance
End-to-end registration of your entity, sender IDs and message templates — the prerequisite for sending any commercial SMS in India, handled for you.
Campaign management and reporting
List management, scheduling, personalisation, delivery-report dashboards, link tracking and API integration into your CRM or software.
Who this is for
- E-commerce and retail businesses sending order updates and offers
- Apps and fintech businesses needing OTP and transactional alerts at scale
- Institutes, clinics and service businesses sending reminders and fee alerts
- Campaigns, events and NGOs that need mass outreach in regional languages
How it starts
Compliance onboarding
We understand the use case and complete DLT entity, sender-ID and template registration — or the equivalent sender registration in other markets.
Setup
Sender IDs configured, contact lists uploaded and cleaned, templates drafted and approved, API integrated where needed.
Launch
Campaigns scheduled and sent; transactional routes go live for continuous automated sending from your systems.
Report and refine
Delivery reports and response data reviewed; timing, segments and templates improved with every send.
Channels and integrations
We only send to audiences with proper opt-in — providers promising promotional SMS to DND numbers are selling you a compliance problem, and we are not one of them.
What it costs
We quote per project after the scoping call, because an honest number depends on scope rather than a price list. These are the factors that move it most:
- Message volume — per-SMS, per-call-second and per-WhatsApp-message rates with volume slabs
- Route type — transactional and OTP priority routes cost more than promotional routes
- Channel mix — WhatsApp marketing messages cost more than utility or authentication messages
- Setup and compliance work — DLT registration, template management and API integration
Engagements run as a fixed-scope project, a dedicated team on monthly contract, or an ongoing support & care plan.
Questions
Can I send promotional SMS to DND numbers?
No. TRAI blocks promotional messages to DND-registered numbers; only transactional and service messages reach them. The legitimate route to market to DND numbers is recorded digital consent through the DLT consent framework, or WhatsApp with proper opt-in. Anyone promising otherwise is offering something non-compliant.
Why do bulk SMS messages get blocked or fail to deliver?
Usually a DLT issue — content that does not exactly match the registered template, a sender ID in the wrong category, or an unregistered entity. We audit your templates and registration as part of setup so campaigns deliver instead of silently dying.
What do I need before I can start sending?
In India: DLT entity registration, an approved sender ID and approved templates — typically ready within about a week. We handle the paperwork; you provide business documents and the message content. Other countries have their own sender-registration processes and timelines, which we manage the same way.
