What it does
Three jobs, done quietly in the background
You bring the list and the offer. SMS Blaster handles everything between “send” and “signed.”
Keeps your texts landing
Sends rotate across your number pool, coolest first, while new numbers warm up from 10 to 500 a day — automatically.
- Coolest-first rotation
- 28-day warmup ladder
- Your Twilio or Telnyx numbers
Makes every text personal
AI drafts your openers, spintax and merge tags vary each message — every contact gets a text that reads typed-for-them.
- One AI key, 200+ models
- Name & address merge tags
- A/B tests pick their own winner
Turns replies into a pipeline
One inbox, leads ranked by warmth, and STOP honored the moment it arrives — checked three separate times before anything sends.
- Hot / warm / cold ranking
- Twilio replies with zero setup
- Quiet hours you set once
How it works
List in the morning, replies by lunch
Step 1
Import your list
Drop in your CSV. Columns map themselves, and duplicates or opted-out folks never make it in. How many contacts you can import depends on your plan: 500, 25,000 or 60,000 per rolling 30 days, or unlimited on Lifetime.
Step 2
Press start
Pick templates and a daily pace. Rotation and warmup run the schedule, and once you set a quiet-hours window it holds sends inside it.
Step 3
Talk to warm people
Hot leads float to the top of your inbox. You spend your day on people who already said “maybe” — or “yes.”
The honest comparison
Shared texting platform vs. your own numbers
Most texting tools route your messages through numbers and servers they control. Here is what changes when the account is yours.
| What matters | Shared platform | SMS Blaster |
|---|---|---|
| Whose numbers | Theirs, pooled with other senders | Your own Twilio or Telnyx account |
| Message cost | Their per-message price, marked up | Carrier rate, billed direct, no markup |
| Your contact list | Stored on their servers | A database on your own PC |
| If they ban you | Account gone, list gone, numbers gone | Your carrier account and numbers stay yours |
| Reply handling | Usually a webhook you must configure | Twilio replies work with zero setup |
| Ramping a new number | Often send-at-will from day one | Warm-up ladder, 10 a day up to 500 |
| A failing number | You notice from the invoice | Auto-paused at 30% failures or 5 opt-outs |
Shared-platform behavior varies by vendor. Compare against your own provider's current terms before switching.
Compliance
The guardrails are in the software
Cold texting goes wrong when an opt-out gets lost between a spreadsheet and a send. These are enforced on the send path, not left to you to remember.
- STOP is automatic. Six standard keywords are caught on every inbound route and recorded the moment they arrive.
- An opt-out cannot be overridden by a campaign. Opted-out contacts are excluded when the audience is built, then checked again per contact immediately before sending.
- Opt-outs outlive your lists. Deleting a list keeps the people in it who opted out, and re-importing the same file never clears one.
- Every campaign message carries an opt-out footer, added by default and not editable from the campaign screen.
- Your list stays on your machine. Local database, interface bound to localhost, provider credentials encrypted on disk.
Plans

Frequently Asked Questions
What people ask before their first blast
Is cold texting legal?
Texting for marketing is governed by the TCPA and by carrier rules, and both are stricter than email. The short version: you need a lawful basis to text someone, you have to honor opt-outs immediately, and you have to respect quiet hours. SMS Blaster handles the mechanical parts — STOP capture, opt-out enforcement, an opt-out line on every campaign message, and a quiet-hours window you configure. Note that it is one global window in your own local time, not per-recipient or per-state, so calling-time rules stay your responsibility. Whether you have consent to text a given person is your call and your responsibility. This is not legal advice.
Do I need my own Twilio account?
Yes. SMS Blaster sends through your own Twilio or Telnyx account, so the numbers, the sender reputation, and the replies belong to you. You pay the carrier directly for messages and number rental, at their price. RoliOh adds no markup and never sits between you and your carrier.
How many texts can I send per day?
Each number climbs a warm-up ladder: 10 a day, then 25, 50, 100, 250, and 500, reaching full power around day 29. Sends rotate across your number pool coolest-first, so no single number carries the load. Warm-up is on by default for numbers you add by hand, and you can turn it off per number if you know what you are doing.
What happens if a number starts failing?
SMS Blaster watches each number and pauses it automatically once it crosses a 30% failure rate or picks up 5 opt-outs, measured after at least 20 sends so a small sample cannot trip it. You keep sending on the healthy numbers while you sort the bad one out. No tool can promise a number never gets filtered — this limits the damage when it happens.
Where are my contacts stored?
On your own PC. SMS Blaster is a Windows desktop app with a local database, and its interface only listens on your machine. Your contact lists and message history do not sit on a RoliOh server, and message content goes straight from your computer to your carrier.
How do replies and STOP requests work?
Twilio replies arrive with no setup at all — no webhook, no public URL, no tunnel to configure. Every inbound message is scanned for the standard opt-out keywords, and anyone who opts out is recorded with a timestamp and checked three separate times before a campaign can send to them again. Replies land in a two-way inbox where leads are ranked hot, warm, cold, or dormant.
What does it run on, and when can I get it?
SMS Blaster is a Windows desktop app, and it runs today. We are handing it out as a private beta rather than an open download, so ask for access below and we will send you the installer and your 7-day trial.
Installing on Windows
SMS Blaster is not code-signed yet, so Windows SmartScreen may show a blue “Windows protected your PC” box the first time you run the installer. Click More info, then Run anyway. We publish a SHA-256 checksum with every build so you can verify the file you got is the file we sent. Windows 10 or 11.
