Walk through Gariahat a week before Durga Puja and you will see how fast a Kolkata business has to move. Offers change daily, customers decide quickly, and a message sent at the right moment can fill a shop or a clinic slot. That is one reason bulk SMS remains popular across the city, from Salt Lake offices to College Street coaching centres.
If you are comparing providers, the page on bulk SMS service in Kolkata from MetaReach Marketing covers the services, Bengali SMS and pricing slabs. Here is the practical overview first.
Why SMS Works Well in Kolkata
An SMS needs no app, no login and no data plan beyond basic network coverage, so it reaches almost every phone. For short, time-sensitive notes such as reminders, alerts and offers, that is a real advantage. It does not replace other channels, but it is a dependable one to have.
Who Uses It, and How
- Retail and showrooms: festive offers and sale announcements, especially around Puja.
- Hospitals and diagnostic centres: appointment and report reminders.
- Education: admission notices, fee alerts and exam schedules.
- Real estate: launch invitations for projects in New Town and Rajarhat.
- IT companies and banks: OTPs, login alerts and EMI reminders.
Mentioning a familiar area such as Park Street, Salt Lake or Jadavpur makes a message feel local and relevant.
Writing in Bengali
Many people respond more warmly to a message in their own language. Bengali SMS is sent as Unicode, and this is where the numbers change. A standard English message allows about 160 characters per segment, while Unicode allows about 70. So a longer Bengali message may use two or three segments, and each one is billed. Short, clear sentences keep costs sensible and also read better. Always test a Bengali template on a few phones, so the characters show properly instead of as question marks.
Message Types in Plain Terms
- Promotional: offers and campaigns, sent to non-DND numbers between 9 AM and 9 PM.
- Transactional: confirmations and alerts for existing customers.
- OTP: one-time passwords where speed matters most.
Rules are updated from time to time, so confirm the current TRAI guidance with your provider before assigning a campaign to a route.
DLT Registration Comes First
Every business sending commercial SMS in India registers its entity, sender ID and templates on the DLT platform. Small mistakes in templates are a common reason for rejection. The page says MetaReach handles this process for clients, so ask exactly what is included, which documents you need and whether operator fees apply.
Planning for Puja and Festival Season
Festival weeks bring heavy traffic, and everyone wants to send at once. A few habits help. Finish your DLT templates well ahead of time. Prepare the message list early and schedule sends rather than doing everything in one rush. Ask your provider how capacity is handled in peak weeks, and whether you need to book ahead.
Understanding the Pricing
The page lists volume slabs from ₹0.40 down to ₹0.12 per SMS, with GST added on top, and custom quotes for smaller volumes. As a simple illustration, 50,000 messages at ₹0.15 would be ₹7,500 before GST. Your actual rate depends on volume and message type, so ask for the exact figure in writing.
Getting Started
The path is usually short. You have a quick call about your needs, complete DLT registration, get access to the panel, upload your contacts, and send a small test campaign. Check the delivery report, then scale up. Timelines depend on how fast approvals come through, so do not leave this to the last day before a sale.
Questions to Ask Any Provider
- Which routes are used, and do reports show delivery per number?
- Who handles DLT, and are there any fees?
- How is Bengali Unicode billed?
- Is an API available for your website or app?
- How do I reach support, and during what hours?
