How to message all your WhatsApp contacts without a broadcast
You can forward a message to a few chats or use a broadcast list (up to 256 people, and only those who saved your number receive it), but a copied announcement gets ignored, and sending to many people who don't have your number saved is how WhatsApp restricts accounts. What works is a short personal message to each person, sent one at a time at a human pace.
Why broadcasts and blasts backfire
Broadcast lists only reach people who saved your number, and everyone can tell a broadcast when they see one. Forwarding the same text to everyone feels like spam to the people who know you best, and they're the ones most likely to buy or refer.
Bulk-sending tools and unofficial “WhatsApp blasters” break WhatsApp's terms. Numbers that start many new chats quickly, especially with people who don't have them saved, get flagged and banned, and that's your personal number.
How it works with Larvabot
- 1Import your contactsA CSV, a pasted list or your phone's contacts export. Add a short note on anyone you want (“old colleague, runs a café”).
- 2Say what you want to tell themThat you've started a business, a new service, an event. One sentence of context is enough.
- 3Get a personal message for eachLarvabot writes each message from your note about that person, so the café owner hears why it matters to a café.
- 4Send one by one, from your WhatsAppPress the button, WhatsApp opens with the message ready, you hit send. Larvabot waits at least 60 seconds between chats and stops at 20 a day to keep your number safe.
- 5Or SMS, Telegram, emailThe same queue works for people you'd rather text, message on Telegram or email.
Example
A caterer launching a lunch service
A caterer imports 140 phone contacts and notes on 30 of them, and writes: “We now do office lunches in Nairobi, delivered by noon.”
- For a former colleague noted as “HR at a 40-person company”, the message asks whether their office still orders lunch for Friday meetings.
- For a friend noted as “runs a co-working space”, it suggests a tasting for members.
- She sends 20 a day over a week, each opened in WhatsApp with one tap, and marks replies as she goes.

Message for James (draft)
Hey James! Hope the new role is treating you well. Quick one: I've started doing office lunches in Nairobi, delivered by noon. Does your team still do lunch for the Friday all-hands? Happy to send over a menu if it's useful, no pressure at all.
What Larvabot won't do
Worth knowing before you start:
- It doesn't send by itself. You press send in WhatsApp for every message; there's no bulk sending and no WhatsApp Business API.
- It doesn't find phone numbers. It works with people you already know.
- With pacing on, WhatsApp is capped at 20 new chats a day across all your projects. SMS, Telegram and email have no limit in Larvabot.
Send the leads where you work
Keep track of who replied by sending contacted people to a Google Sheet or CRM with Zapier or Make, or export the list as CSV.
Questions people ask
How do I send one message to all my WhatsApp contacts at once?
WhatsApp only allows broadcast lists of up to 256 contacts, and only people who saved your number get the message. To reach everyone safely, send personal messages one at a time; Larvabot writes each one and paces them.
Will WhatsApp ban me for messaging lots of contacts?
It can restrict numbers that start many new chats quickly, especially with people who don't have the number saved. Sending a few personal messages a day, with gaps between them, keeps you well inside normal use.
Do I need WhatsApp Business for this?
No. Larvabot opens your normal WhatsApp (or WhatsApp Business, if that's what you use) with the message ready. There's no API account to set up.
