Okay so listen, you’ve probably seen or even recieved one of those texts like “Get 20% off today only!!” or “Your OTP is 8723”. That stuff? That’s bulk SMS. And yeah, it’s still very much a thing, even now in 2025. Suprised? Same.
With all the fancy tech we got now — WhatsApp campaigns, Insta ads, email marketing tools and whatnot — you’d think SMS would be dead, right? But nope. Turns out, SMS still hits. Hard.
So let’s talk about it. What bulk SMS services actually are, who uses them, how they work, why they’re still kinda effective, and where they fall short too. Also gonna throw in some real talk because people overhype stuff sometimes.
So What is Bulk SMS Anyway?
In simple words — bulk SMS is sending a lot of SMS messages at once. Instead of texting each person one by one, businesses use bulk SMS tools to send hundreds or thousands of messages in just one go.
For exampel, a store might send a text to 10,000 customers like “Sale ends today – grab your deal now!”. Or a school sending reminders to all parents about a holiday. That’s bulk SMS.
Used for:
-
Promotions
-
OTPs
-
Alerts
-
Order confirmation
-
Reminders
-
Notifications
-
Surveys sometimes
The messages are short, straight to the point, and meant to get noticed fast.
How Does It Even Work?
So basically, a business signs up with a bulk SMS provider (like a platform or gateway). They give you a dashboard (or API if you’re techy) where you upload your contacts, type the message, and send it out to everyone in your list.
Simple stuff.
Some let you schedule SMS, some let you add the person’s name (like “Hi Raj”), and some even let you track who clicked on the link inside the message.
All the heavy lifting is done by the SMS gateway – they route your messages through mobile networks and boom, it goes to all the numbers.
Who’s Using This Stuff?
You’d be shocked how many people still use SMS for business:
-
Ecom websites (Flipkart, Amazon, etc) for order updates
-
Schools for fees reminder or holidays info
-
Gyms and clinics for appointment reminders
-
Local shops for sales promotions
-
Banks for OTPs and alerts
-
Event people for ticket info
-
Startups for user onboarding
Basically, everyone who wants fast communication and don’t wanna rely on people checking their email.
⚡ Why Bulk SMS Still Works (Even in 2025)
Alright, so people are always saying “SMS is dead”. But… here’s the thing.
SMS has something that no other platform fully matches:
It gets opened.
Like, literally 90–98% open rate. Compare that with email (20–30% max) or social media posts that get buried in algorithm hell.
Here’s why it still works:
-
Fast AF – Messages deliver in seconds.
-
High visibility – People check SMS more than email.
-
No internet needed – Even your uncle’s 2G phone gets it.
-
No app required – It’s just SMS.
-
Great for OTPs and alerts – Can’t rely on email for that stuff.
But It’s Not All Perfect Tho…
Let’s not act like bulk SMS is some miracle tool. It’s not flawless. There’s downsides, like:
✖️ 1. Short Message Limit
Only 160 characters per SMS. That’s like… not much. You gotta write tight.
✖️ 2. People Ignore Spammy Stuff
If you just keep saying “SALE SALE SALE”, people will start ignoring you. Or worse, block you.
✖️ 3. DND & Regulations
In countries like India, DND (Do Not Disturb) filters block promotional SMS to registered numbers. And now there’s DLT rules and templates to deal with (ugh).
✖️ 4. Delivery Issues Sometimes
Not always, but sometimes SMS don’t reach the user. Especially if your SMS provider sucks.
✖️ 5. No Images / Rich Media
Plain text only. No pics, no buttons, no videos. Can be boring.
What’s the Cost Like?
So, price depends on the country, the type of SMS (promotional or transactional), and the volume. In India for example:
-
Promotional SMS: ₹0.10 to ₹0.20 per SMS
-
Transactional SMS: ₹0.15 to ₹0.30 per SMS
-
DLT charges may be extra
Most platforms have packages, like 10,000 SMS for ₹1,000 or ₹1,500. The more you buy, the cheaper per SMS.
In the US or UK, it’s obviously more expensive.
Also – make sure you’re not paying extra for fake delivery reports. Some shady providers do that.
✅ What to Look for in a Bulk SMS Service
Okay if you’re actually thinking of using bulk SMS, don’t just pick the cheapest one. That’s how people end up with undelivered messages and zero support.
Here’s what to check:
-
Good delivery rate (over 90%)
-
Dashboard that’s easy to use
-
DLT registration (if you’re in India, you need this now)
-
Decent support (at least chat or phone)
-
API access if you wanna automate stuff
-
Real delivery reports
-
Free trial (why not test it before paying?)
Popular providers: MSG91, Textlocal, Twilio, Gupshup, Exotel etc. But test it before going all in.
Tips for Using Bulk SMS Properly
If you’re gonna use it, don’t be annoying. That’s how brands get blocked.
Here’s some real-life tips:
-
Send SMS at right time – Not 2AM pls
-
Make it short but clear
-
Add a CTA – like “Use Code: SAVE20” or “Call us now”
-
Use link shorteners if needed (like Bit.ly)
-
Don’t send daily unless it’s really needed
-
Personalise if you can (like “Hey Priya”)
-
Track clicks if possible
Basically: be useful, not spammy.
So… Is Bulk SMS Still Worth It?
Honestly? Yes. But only if you use it smart.
If you’re just blindly blasting out boring messages to random people, you’re wasting money and annoying users.
But if you’re sending useful, timely, clear messages to the right audience — it’s still one of the best tools for fast, wide reach.
Especially for OTPs, alerts, and quick promos, SMS beats email and even WhatsApp in many cases. No internet needed, no app needed, just boom – straight to inbox.
Final Thoughts
Look, bulk SMS might not be sexy or trending right now. No one’s making YouTube videos saying “SMS is the future” lol. But in the background, it’s still quietly doing its job.
If you’re a business, startup, freelancer — don’t sleep on SMS. Just make sure you:
-
Pick a good provider
-
Follow the rules (DLT, templates etc.)
-
Write good messages
-
Don’t overdo it
Done right, bulk SMS can get you real attention, leads, sales — whatever your goal is.
Old doesn’t mean dead. Sometimes it just means trusted.
