What is a one-time WhatsApp broadcast?
A one-time WhatsApp broadcast is a single message sent to a list of recipients, without setting up a permanent broadcasting system. With Gambot you do not need a business WhatsApp number, business verification with Meta or a subscription: messages go out through Gambot's verified WhatsApp Business API account, and the price includes WhatsApp fees.
It suits anyone who needs to send a message once, or once in a while — for example to invite people to join a WhatsApp group — and does not want to wait for verification, set up a number or pay a monthly fee. If you broadcast on a regular schedule, move to a recurring WhatsApp broadcast or the full WhatsApp broadcast system.
What people use one-time broadcasts for
Updates channel & community
Invite your audience to an updates channel or a new club, without building a permanent broadcasting setup.
Event, meetup or lecture
A one-off invitation to an event, open day or launch — with a registration button and link.
Limited-time sale
A promotion that ends in a few days? One message to your customers with a coupon code and a purchase link.
New number or address
“We moved to a new WhatsApp number” or “We moved to a new branch” — one update to the whole list.
Quick survey or request
A one-time survey, donation request, volunteer call or waiting list.
How it works — 4 steps
- Upload an Excel file. Upload a spreadsheet with phone numbers (and personal fields such as a name, if you like). The system validates the numbers and filters out invalid numbers, landlines and duplicates.
- Write the message. Write your message with personal fields from the file and add a button (link, call or quick reply) — or pick a ready-made template from the library, for example “Invitation to join a WhatsApp group”.
- Pay. A calculator shows the exact price before you pay. You pay by credit card on a secure page and receive an invoice.
- Schedule. Pick a date and time to send (at least 25 hours ahead, so Meta has time to approve the template). You get an email when the template is approved, an email when the broadcast finishes, and a results report about a day later.

Good to know before you order
- Gambot is the sender. The message goes out from Gambot's number and ends with “Sent by Gambot on behalf of [your business name]”. Recipients' replies do not reach you — add a website or call button.
- Scheduled in advance. The send is scheduled at least 25 hours ahead because of Meta's template approval.
- Only to people who agreed. Send only to people who consented to receive messages from you; you are responsible for the content and the list.
- Mobile numbers only. Landlines, invalid numbers and duplicates are not sent and not charged.
Frequently asked questions
How do I send a one-time WhatsApp message to a list without setting up a broadcasting system?
Use a ready-made one-time broadcast service such as Gambot's: upload an Excel file of phone numbers, write the message, pay and schedule. You do not need a business WhatsApp number, Meta business verification or a subscription. Messages are sent from Gambot's verified number and the price includes WhatsApp fees.
Can I send an invitation to join a WhatsApp group to a list of people?
Yes. It is one of the most common uses. Write a short message with a link button that leads to the group (or channel) invitation and send it to the whole list. Recipients join in one tap. A ready template is available in the library.
Do I need a dedicated phone number or Meta business verification?
No. The broadcast is sent through Gambot's verified WhatsApp Business API account, so you do not have to set up a number, pass business verification or open your own account.
How much does it cost?
Graduated pricing: 1–500 messages — ₪0.9 per message; 501–2,000 messages — ₪0.75 per message; 2,001–5,000 messages — ₪0.65 per message; 5,001–10,000 messages — ₪0.58 per message. Minimum order ₪49. All prices are before VAT (18%), include WhatsApp/Meta fees and apply to recipients in Israel — for other destinations Meta's rate may be higher and the calculator shows it.
When are the messages sent — can it be immediate?
Ordering takes minutes and needs no advance setup. The send itself is scheduled at least 25 hours ahead because every message template is approved by Meta (usually within 24 hours). You receive an email as soon as the template is approved.
What happens if Meta rejects the message?
If the template is rejected we come back to you to fix it at no extra charge, and the broadcast is rescheduled.
What do recipients see, and where do replies go?
The message is sent from Gambot's number and the line “Sent by Gambot on behalf of [your business name]” is added automatically at the bottom. Recipients' replies do not reach you, so add a website or call button that sends people to you directly.
What reports do I get?
An email when the template is approved, an email when the broadcast finishes, and about a day after sending a results report: how many messages were sent, delivered and read, how many people clicked buttons and links, and what they replied.
Can I send to any list?
Only to people who agreed to receive messages from you. When ordering you confirm that you have such consent and that you are responsible for the content and the list. Recipients can ask to be removed. Marketing messages without consent are prohibited by law and by Meta's policy.
What if I have more than 10,000 recipients, or need hands-on help?
For large volumes or full service there is Gambot's managed broadcast service, and for recurring broadcasts you can open a full WhatsApp broadcasting system with a free trial.
