Quick Answer
Bulk SMS marketing is sending targeted promotional text campaigns, such as offers, launches, loyalty rewards and win-back messages, to large segments of opted-in mobile numbers. In India these go on -P headers with DLT-registered templates, an opt-out option and the promotional time window. SMSGatewayHub adds segmentation, personalised fields, scheduling, link click tracking and live delivery reports, and you pay only for delivered SMS.
Which bulk SMS marketing campaign should you run?
Start from the business goal, then pick the campaign type and the segment most likely to respond. Every campaign below is promotional and goes out on a -P header.
| Campaign type | Business goal | Best segment to target | Timing tip |
|---|
| Offer and flash sale | Quick revenue, clear stock | Recent buyers and engaged clickers | Announce a clear end date and send a last-chance reminder |
| New product or store launch | Awareness and first orders | Customers who bought the related category or live near the store | Send a few days before launch, then on launch day |
| Loyalty and rewards | Repeat purchases | Members with unused points or rewards | Before points expire or around birthdays and anniversaries |
| Win-back and re-engagement | Return of lapsed customers | No purchase in your typical buying cycle | One strong offer, then stop if there is no response |
| Cart and browse reminders with an offer | Recover abandoned orders | Known customers who left items behind | Within hours of abandonment, while intent is fresh |
| Event and webinar invites | Footfall and registrations | City, interest or past attendees | Invite early, remind the day before |
| Festival and seasonal campaigns | Seasonal demand | Region and language of the festival | Plan ahead of the festive window; send in the regional language |
| Lead capture | New opted-in contacts | Walk-ins, ad viewers and event visitors | Ask them to give a missed call or text a keyword to opt in |
Order updates, payment alerts and reminders without an offer are not marketing: send them as transactional or service SMS so they reach every number 24/7. For quick copy ideas, see our marketing bulk SMS tips.
What changed for SMS marketing campaigns under the latest TRAI rules?
Four rule changes now shape who you can reach, what your message must contain and how fast complaints count against you.
-P suffix on every campaign
Operators label promotional headers with -P, and the former service explicit category now follows promotional rules too. Never route offers through -T or -S templates. Sender IDs & suffixes
Opt-out in every message
Each promotional message must give the customer a way to opt out. Once someone revokes consent, you cannot ask them for it again for 90 days.
Complaints act faster
Customers can report spam without first registering a preference, and action against a sender now starts after fewer complaints in a shorter period. Relevance and consent protect your header.
Whitelisted links and typed variables
Every URL or callback number must be a whitelisted CTA, and variables must be tagged as {#numeric#}, {#url#} and so on. See DLT sample templates.

Bulk SMS marketing vs promotional SMS: which do you need?
Promotional SMS is the route: the -P header, DLT templates, DND scrubbing and the 10 AM to 9 PM window that every marketing message travels on. Bulk SMS marketing is the strategy on top of it: which campaign to run, which segment to target and how to measure the return. You need both, and on SMSGatewayHub they run from the same account.
If you want quick copywriting and list tips, start with our marketing bulk SMS page. For customers who have blocked promotions or want richer media, add WhatsApp Business API or RCS with opt-in. For a wider view of the channel, read SMS marketing in India.
Frequently Asked Questions
What is bulk SMS marketing?
Bulk SMS marketing is sending targeted promotional text campaigns, such as offers, launches, loyalty rewards and win-back messages, to large groups of opted-in mobile numbers. In India these campaigns use -P headers and DLT-registered promotional templates. SMSGatewayHub provides the panel, API, segmentation and reports to run them.
Which SMS marketing campaigns work best?
It depends on the goal: flash sales for quick revenue, loyalty reminders for repeat purchases, win-back offers for lapsed customers and launch alerts for new products or stores. Results are best when each campaign goes to the segment most likely to act on it, rather than to the whole list.
How do I segment contacts for SMS campaigns?
Add columns such as city, last purchase date, category, spend or language to your contact file and split the list on them. SMSGatewayHub lets you import CSV or Excel files with custom fields, remove duplicates and send a different message to each segment.
What are the TRAI rules for promotional SMS campaigns?
Promotional messages carry a -P header suffix, must match a DLT-registered template, are delivered only in the promotional time window and reach DND numbers only with recorded consent. Every message must offer an opt-out, and once consent is revoked you cannot ask again for 90 days. SMSGatewayHub's DLT team helps you register compliant templates.
How do I measure the ROI of an SMS marketing campaign?
Track delivery rate, link clicks, replies and opt-outs for each campaign, then match unique offer codes or tagged links to orders in your store or CRM. Divide delivered SMS spend by conversions to get cost per conversion, and repeat the segments and offers that perform best.
Can I send marketing SMS to DND numbers?
Only to customers who have given you recorded consent; otherwise DND numbers that have blocked promotions are filtered out. For those customers, use transactional or service SMS for genuine alerts, or WhatsApp Business API with opt-in. SMSGatewayHub scrubs your lists automatically before sending.
What does bulk SMS marketing cost with SMSGatewayHub?
SMSGatewayHub uses Pay As You Go pricing: you buy credits as needed and pay only for delivered SMS; exact rates depend on volume and route, see https://www.smsgatewayhub.com/pricing or talk to sales on 1800 102 1822.
