New WhatsApp blast
From $49/moShort answer: WhatsApp blast software lets you send one message to thousands of people at once, with each recipient getting it as a private one-to-one chat rather than a group. The safe way to do it in 2026 is the official WhatsApp Business API. WaBulkSend is built as a no-code blast tool on that API: you import contacts from a CSV or Excel file, build an approved template, personalize it with each person's name, and broadcast on a schedule while pacing protects your number. Plans are flat from $49 a month, with a one-time demo of 25 messages to try it first.
WhatsApp messaging tiers and per-message fees referenced below are set by Meta and can change; verify current limits and rates before you scale.
What a WhatsApp blast is, and why teams send them
A WhatsApp blast is a single message sent to many recipients at the same time. Unlike a group chat, where everyone can see each other and reply to the whole room, a blast lands in each person's inbox as a private conversation. That is why blasts feel personal: the message arrives in the same thread as chats from friends rather than in an email promotions tab. For a US business with an opted-in list, a blast is the fastest way to put an offer, a reminder, or an update directly in front of customers who actually read it.
The catch is how you send it. Typing the same message to hundreds of people by hand is not realistic, and the free WhatsApp Business app caps a broadcast list at 256 contacts who must also have saved your number first. Plenty of browser extensions and desktop "blaster" apps promise to get around that by automating your personal account, but WhatsApp detects that pattern quickly and bans the number. So the real question for a buyer is not whether you can blast, it is how to blast at scale without losing your number. That is what a WhatsApp bulk messaging platform on the official API is for, and it covers the messaging limit tiers and per-recipient delivery reporting a blaster app cannot give you.
That is the job WaBulkSend is built for. It runs on the official WhatsApp Business API, the same channel Meta sanctions for business messaging, so your sends are legitimate rather than something WhatsApp is trying to block. You upload your contacts, build a template and submit it for approval, personalize each message with merge fields, and send to your whole list while the platform paces delivery to keep your quality rating healthy. If you have used a WhatsApp broadcast tool or a WhatsApp bulk sender before, a blast is the same idea: one message, many private recipients, sent the compliant way.
What you get in the blast tool
Everything you need to send a WhatsApp blast that gets delivered, gets read, and keeps your number in good standing.
CSV and Excel import
Upload your contact list from a CSV or Excel file and map columns in seconds. No copy-paste, no manual entry, no 256-contact ceiling.
Approved template builder
Create your blast message, add variables and buttons, and submit it for Meta approval right inside the app. Approval usually lands in minutes.
Personalization
Merge each contact's name, order, city, or any column from your file so a blast to thousands still reads like a one-to-one note.
Smart throttling
Sends are paced automatically and back off when Meta throttles, and a sending window keeps them out of quiet hours, so a large blast goes out steadily instead of in one spike.
Scheduling
Queue a blast for a set date and time in your chosen time zone, use the best send time suggestion, or repeat it daily, weekly, or monthly without watching the clock.
Delivery analytics
Track sent, delivered, read, replied, and failed for every recipient of every blast, with Meta's error reason on each failure, and export the results to CSV.
How to send a WhatsApp blast in four steps
From a spreadsheet of contacts to a delivered blast, no code and no developer required.
Connect your number
Connect your own WhatsApp Business Platform number by pasting its phone number ID, WABA ID, and access token. Your brand, your number, your Meta account.
Import your contacts
Upload your opted-in list from a CSV or Excel file. Tag and segment so each blast goes to the right people.
Build your template
Write your blast, add merge fields and buttons, and submit it for approval. Personalization keeps it out of the spam bucket.
Send and track
Launch the blast now or schedule it. Automatic pacing keeps the send steady while you watch delivered, read, and replied update for every recipient.
Most teams blast straight from a spreadsheet. If your audience already lives in Excel, you can send WhatsApp messages straight from an Excel file by importing it directly, no reformatting required.
Official blast software vs a free WhatsApp blaster
A free Chrome blaster looks cheaper until WhatsApp bans the number you built your business on. Here is the honest comparison.
| What matters | Free blaster (extension or app) | WaBulkSend (official API) |
|---|---|---|
| How it sends | Automates your personal or Business app account | Sends through the official WhatsApp Business API |
| Ban risk | High, WhatsApp detects automation and bans numbers | Low, business sending is sanctioned by Meta |
| Volume per day | A few dozen before throttling or a block | 1,000 to start, scaling to 10,000, 100,000, then unlimited |
| Personalization | Manual or none | Per-contact merge fields from your file |
| Delivery tracking | None or unreliable | Delivered, read, and replied in real time |
| Templates | Free text, easily flagged as spam | Pre-approved templates, compliant by design |
| Opt-in and compliance | Usually ignored | Built around opt-in and Meta's messaging policy |
| Your number | At risk of a permanent ban | Protected on a compliant sender |
| Real cost | "Free" but it can cost you your number | From $49 a month, predictable |
Honest take: a free blaster can work for a one-off message to a handful of contacts. The moment a blast looks like marketing at scale, WhatsApp's systems flag it, and the account you lose is the one customers already have saved. Official API sending costs a little more and removes that risk entirely.

WhatsApp blast questions, answered
What is a WhatsApp blast?
A WhatsApp blast is a single message sent to many recipients at once, where each person receives it as a private one-to-one chat instead of a group thread. Businesses use blasts for promotions, reminders, and updates because they reach an opted-in list directly and WhatsApp open rates routinely top 90 percent.
How do I send a WhatsApp blast?
To send a WhatsApp blast, use blast software built on the official WhatsApp Business API. Connect your number, import your opted-in contacts from a CSV or Excel file, build and approve a message template, personalize it with merge fields, then send to the whole list. The tool paces delivery so a large blast does not trigger a ban.
Is WhatsApp blasting legal?
Yes, WhatsApp blasting is legal when you send to people who opted in and you follow WhatsApp's messaging policy. The issue is never the blast itself, it is consent and method. Sending business messages on the official API to an opted-in list is allowed; spamming strangers from a personal account using an unofficial blaster is not.
Can you get banned for blasting on WhatsApp?
Numbers get banned when a business blasts from a personal account using an unofficial extension, sends without opt-in, or behaves like spam. You greatly reduce that risk by sending on the official WhatsApp Business API with approved templates, opted-in contacts, and throttled delivery, which is exactly how WaBulkSend is built.
How many contacts can I blast on WhatsApp?
The free WhatsApp Business app limits a broadcast list to 256 contacts who have saved your number. On the official Business API there is no list cap; new senders start around 1,000 unique recipients per day and scale automatically to 10,000, 100,000, and eventually unlimited as your quality rating stays high.
How do I blast a WhatsApp message from Excel?
Export your contacts to a CSV or Excel file with a column for phone numbers and any personalization fields, then import that file into your blast software. WaBulkSend will map the columns, merge each person's details into the template, and send the blast, so you never copy and paste numbers by hand.
What is the best WhatsApp blast software?
The best WhatsApp blast software runs on the official WhatsApp Business API, imports contacts from a spreadsheet, builds approved templates, personalizes each message, and throttles delivery to protect your number. WaBulkSend does all of that with no code, from $49 a month, with a one-time demo of 25 messages so you can test a blast before you pay.
Can I send WhatsApp marketing campaigns to US phone numbers?
Not at the moment. Meta does not deliver marketing templates to WhatsApp users with US phone numbers (+1 with a US area code) and returns error 131049. This has applied since April 1, 2025 and Meta has announced no end date. Utility and authentication templates still deliver to US numbers, and Canada and other countries are not affected. When a campaign uses a marketing template, WaBulkSend leaves US numbers out before sending, so they do not use up your plan allowance.
