An SMS blaster sends one text message to a whole list of phone numbers at once: a sale, an open house, a reminder or an event. Which SMS blaster is right for you comes down to one thing, the size of your list. Here are the three kinds, what each costs, and which to pick.
Quick answer: a phone app for a few dozen people, SMS blaster software for hundreds to tens of thousands, and a managed SMS blast service once your list reaches 100,000+.
1. SMS blaster apps (free, for small lists)
Phone apps and your phone's own settings can send one text to many contacts separately. They are free because they use your own number and plan. That is also their limit: they suit a few dozen people, not a customer list. Send the same text to hundreds of numbers from a personal line and carriers start filtering it. Our guide to sending a mass text from iPhone or Android shows the exact settings.
Skip "SMS blaster APK" downloads from outside the app stores. They are a common way to get malware onto a phone.
2. SMS blaster software (for regular sends)
Self-serve SMS blaster software runs in your browser. You create an account, upload contacts, write the message and send or schedule it. Most platforms charge a monthly plan plus a fee for every text, and you do all the setup and sending yourself.
It works well if you text a few hundred to tens of thousands of customers every week and want two-way conversations. For one big campaign, the per-message fees add up fast: at $0.01 to $0.025 per text, 500,000 messages costs $5,000 to $12,500.
3. A managed SMS blast service (for 100,000+ texts)
With a managed service you don't run any software. You hand over your list and your message, and the campaign is sent for you. That is what Smarterblast does:
- Choose a package by list size: Bronze $449 for up to 100,000 texts, Silver $699 for up to 500,000, Gold $999 for up to 2,000,000.
- Pay in crypto. You don't need your list yet.
- Upload your list and message through the private link we email you once payment is confirmed.
- We send the campaign and email you the delivery report.
Every package carries our 70% delivery guarantee: if fewer than 70% of the valid numbers on your list are delivered, we refund the package price.
| SMS blaster | Best for | Cost | Your effort |
|---|---|---|---|

What to look for in an SMS blaster
- Total cost for your list, not the price per text. Add up every fee for the campaign size you actually send.
- A delivery guarantee. Ask what happens if messages don't arrive. Most providers keep your money anyway.
- A delivery report after every send, so you can see what landed.
- How much work it is. Software you have to learn, or a service that sends for you.
- A message that gets replies. Lead with your name and the offer, ask for one action, and end with "Reply STOP to opt out". Our guide to writing a text blast that gets replies has examples.

What is an SMS blaster?
An SMS blaster is any tool that sends one text message to a large list of phone numbers at once. It can be a phone app for small lists, SMS blaster software you run yourself, or a managed SMS blast service that sends the campaign for you.
Is there a free SMS blaster?
Free SMS blaster apps exist, but they send from your own phone number and plan, so they only suit a few dozen contacts. Free tiers of SMS blaster software are trials with a small number of credits. Sending to thousands of people always costs money, because every text goes through the carrier networks.
What is the best SMS blaster for 100,000+ texts?
At that size, a managed SMS blast service is usually the cheapest and least work. Smarterblast sends up to 100,000 texts for $449, up to 500,000 for $699 and up to 2,000,000 for $999, with a 70% delivery guarantee.
How much does it cost to blast 100,000 texts?
Per-message SMS blaster software typically charges around $0.01 to $0.025 per text, which is $1,000 to $2,500 for 100,000 messages before fees. A Smarterblast Bronze package covers up to 100,000 texts for $449, one time.
Is this the same as the SMS blaster scams in the news?
No. Those are fake cell towers that criminals use to push scam texts to nearby phones. A legitimate SMS blast service sends your message through the mobile carriers to the people on your own list.
