How to Use Bulk WhatsApp Message Sender
Send personalised WhatsApp messages to hundreds of contacts at once โ no broadcasting limits, no saved contacts required, completely free.
๐ What Is the Bulk WhatsApp Message Sender?
The Bulk WhatsApp Message Sender is a free online tool that lets you send a single WhatsApp message โ or personalised variations of it โ to multiple phone numbers at the same time, without the need to save each contact to your phone first. It is the fastest and most efficient way to reach a large audience on WhatsApp without juggling individual chats one by one.
Whether you are a business owner announcing a sale, a teacher sending assignment reminders to a class, an event organiser sharing RSVP details, or a marketer running a WhatsApp campaign, the Bulk Message Sender streamlines the entire process into a few simple steps: add your numbers, write your message, and send โ all from your browser.
Unlike WhatsApp's built-in Broadcast feature, which requires recipients to have your number saved to receive the message, the Bulk WhatsApp Message Sender works by opening WhatsApp Web for each number so the message is delivered as a direct chat โ regardless of whether your number is saved by the recipient.

๐ ๏ธ How to Use Bulk WhatsApp Message Sender โ Step by Step
Sending to hundreds of WhatsApp contacts takes just a few minutes. Here is the complete guide:
Open the Tool in Your Browser
Go to whatolls.sbs/tools/bulk-message-sender on your desktop or mobile browser. No installation, sign-up, or login is required โ the tool is ready to use immediately, completely free.
Add Your Phone Numbers
Enter the phone numbers you want to message โ one number per line โ in the recipients box. Always include the full international dialing code (e.g. +92 for Pakistan, +1 for USA, +44 for UK). You can also upload a CSV file containing your contact list to populate all numbers automatically.
Write Your Message
Type your message in the message box. To personalise messages for each recipient, use variables like {name}, {company}, or {city} โ the tool will automatically replace these with the matching data from your contact list. You can also add emojis, formatting, and links.
Validate Your Numbers
Click the Validate button. The tool instantly checks all entered numbers for correct format, valid country codes, and proper digit length. Invalid numbers are highlighted in red so you can fix or remove them before sending โ preventing any failed deliveries.
Set the Send Delay (Recommended)
Choose a delay between messages โ for example, 5 to 15 seconds per message. This makes the bulk send look more natural and significantly reduces the risk of WhatsApp flagging your account for unusual activity. For large lists, a delay of 10โ30 seconds is recommended.
Click Send and Monitor Progress
Press the Send button. WhatsApp Web opens automatically for each number in sequence. The tool shows a live progress bar and a counter of sent versus pending messages. Keep the browser tab open until all messages are sent โ do not close the tab mid-send.
Review the Send Report
Once complete, the tool displays a full send report showing total messages sent, any numbers that failed, and a success rate percentage. You can export this report as a CSV for your records or for follow-up campaigns.

๐ก๏ธ How to Use Bulk Messaging Safely
To protect your WhatsApp account and ensure high delivery rates, follow these best practices when using the Bulk Message Sender:
Always Use a Send Delay
Set a delay of at least 5โ15 seconds between each message. Sending too fast to too many numbers in a short time can trigger WhatsApp's spam detection systems and risk account restriction.
Send Only to Opted-In Contacts
Only send bulk messages to people who have given you consent to receive WhatsApp messages from you. Unsolicited messages lead to spam reports, which can permanently ban your WhatsApp number.
Personalise Your Messages
Generic copy-paste messages are more likely to be reported as spam. Use the {name} variable and other personalisation options to make each message feel genuine and individual.
Validate Numbers Before Sending
Always run number validation before clicking Send. Attempting to message invalid or non-existent numbers can signal suspicious activity to WhatsApp and affect your account standing.
