Bulk WhatsApp messages are the same message sent to many contacts at once, with each person receiving it as a private one-to-one chat rather than a visible group. You import a list, write the message once, add personalization like a first name or order number, and send to everyone in a single run. It is how a business reaches thousands of customers on WhatsApp without typing the same thing over and over.
The catch most people hit is volume. The free WhatsApp Business app caps a broadcast list at 256 contacts, and those messages only reach people who saved your number. The moment you want to message ten thousand customers, that path stops working. The official WhatsApp Business API removes the cap entirely, and recipients do not need to save your number to receive your message.
WaBulkSend sends bulk WhatsApp messages on the official API. There is no contact limit per send, your daily volume scales automatically as your sender reputation grows, and the platform throttles delivery so you stay inside WhatsApp's rate limits. You get the reach of mass messaging with the safety of doing it the way WhatsApp actually sanctions.
How many bulk WhatsApp messages can you send per day?
On the official API, your daily limit starts modest and scales automatically as you send quality messages people do not block.
WhatsApp raises your tier automatically. The rule of thumb is to use at least half of your current daily limit within a seven-day window while keeping a high quality rating, and Meta reviews your number for an upgrade every few hours. Limits count unique conversations, not raw messages, and they only apply to messages your business starts. Replies inside a conversation a customer opened do not count against the cap. For the full picture on rates and setup, see the WhatsApp Business API page.

Bulk WhatsApp messages questions, answered
How do I send bulk WhatsApp messages?
Import your contacts from a CSV or Excel file, write one message or pick an approved template, add personalization variables, then send to your whole list at once or schedule it. On the official WhatsApp Business API, which WaBulkSend runs on, there is no 256-contact limit and recipients do not need to save your number, so a single run reaches your entire audience.
How many bulk WhatsApp messages can I send per day?
On the official API your daily limit depends on your messaging tier. It starts at 250 conversations a day before verification and 1,000 after, then scales automatically to 10,000, 100,000, and finally unlimited as you send quality messages people do not block. The tier counts unique business-initiated conversations per 24 hours, not individual messages.
Can I send bulk WhatsApp messages from Excel?
Yes. With WaBulkSend you upload your contacts from an Excel or CSV file, map columns like name and order number, and those fields pull straight into each personalized message. You do not format anything by hand or paste numbers one at a time, which is how most businesses load several thousand contacts before a send.
Is there a limit to how many people I can message at once?
On the free WhatsApp Business app, yes, a broadcast list is capped at 256 contacts who saved your number. On the official WhatsApp Business API there is no per-send contact limit. WaBulkSend sends through the API, so one run can go to your entire list, bounded only by your daily messaging tier, not a fixed contact cap.
Do recipients need to save my number to get a bulk message?
On the free Business app, yes, broadcasts only reach people who saved your number. On the official WhatsApp Business API, no. WaBulkSend sends through the API, so opted-in recipients get your message whether or not they saved your number, which is the main reason businesses move off the consumer app for bulk sends.
How do I send bulk WhatsApp messages without getting blocked?
Use the official WhatsApp Business API instead of a browser extension, message only people who opted in, send at a steady throttled pace, and honor opt-outs immediately. WaBulkSend spaces out delivery and respects your messaging tier so you stay inside WhatsApp limits. Blasting a cold list from the regular app is the fastest way to trip spam detection and lose your number.
Is sending bulk WhatsApp messages legal?
Yes, when you use the official WhatsApp Business API and message people who gave consent. Bulk messaging on the API is fully sanctioned by WhatsApp, as long as you use approved templates for business-initiated messages and offer a clear opt-out. The tools that get businesses banned are unofficial extensions that automate the consumer app against WhatsApp terms.
How much does it cost to send bulk WhatsApp messages?
Since July 1, 2025 Meta charges per message, not per conversation, and only when a template message is delivered. The rate is set by the template category and the recipient country, and Meta publishes it in a downloadable rate card rather than in its docs. In the US, marketing templates are not delivered at all, so your billable traffic is utility and authentication templates. WaBulkSend adds a software plan on top, starting free for your first 500 messages a month so you can test before you scale.
