Bulk SMS for businesses in Kolkata
Kolkata is the commercial centre of eastern India. Burrabazar is one of the country's largest wholesale markets, the city remains the home of India's jute industry along the Hooghly and a major centre for tea trading and auctions, and the Kolkata port serves eastern India as well as Nepal and Bhutan. Traders and distributors in Kolkata use SMS for order confirmations, payment reminders and dispatch notes to retailers across West Bengal and the Northeast.
Salt Lake Sector V and New Town host the city's IT and ITES offices, while hospitals, schools, coaching centres and jewellery and saree retailers are heavy users of reminders and offers. Durga Puja is the year's biggest retail season, so promotional campaigns cluster in the weeks before it. Bengali-script messages feel natural to most local customers.
For Burrabazar traders and distributors in Kolkata, a short Bengali or Hindi payment reminder with the invoice number usually works better than a long message. Puja and Poila Baishakh campaigns should be scheduled well within the promotional window, and retailers can follow up with RCS or WhatsApp catalogues for richer product images.
Example DLT-style templates (Bengali and English, illustrative only; register your own wording on DLT before use):
Bengali, dispatch
প্রিয় {#var#}, আপনার অর্ডার {#var#} আজ পাঠানো হয়েছে।
Bengali, Puja offer
পুজো অফার: {#var#} স্টোরে {#var#}% পর্যন্ত ছাড়। শেষ তারিখ {#var#}।
English, payment due
Dear {#var#}, payment of Rs {#var#} against invoice {#var#} is due on {#var#}. Please ignore if already paid.
A few rules apply to every sender in Kolkata: register your entity, six-character sender ID and templates on DLT before sending; keep promotional campaigns inside the 9 am to 9 pm window set by TRAI; and remember that Bengali (Unicode) messages are counted per 70-character part, not 160. Our team helps with DLT registration and template wording during onboarding.
