How to send bulk WhatsApp messages (step by step)

QUICK ANSWER

To send bulk WhatsApp messages, prepare a contact list with phone numbers and any personalization fields, import it into a tool like Beamiro on WhatsApp Web, write one message using variables such as {{name}}, choose a delay between sends, and start. Each contact receives a private, individual message.

What "bulk" really means on WhatsApp

Bulk sending does not mean posting to a group. It means sending the same message individually to many people, so each person gets a private one-to-one chat and never sees the other recipients. This feels personal and avoids the noise and opt-outs that groups create.

WhatsApp itself offers broadcast lists for this, but they are capped at 256 saved contacts and only reach people who have saved your number. A dedicated tool removes those limits and the manual work.

Step by step

Build your list

Put phone numbers (with country code) in one column and fields like name or city in their own columns. Save as .xlsx or .csv.

Install a sender

Add a tool such as Beamiro to Chrome and open WhatsApp Web with the number you want to send from.

Import and map

Import the file and tell the tool which column is the phone number and which are variables.

Write once, personalize

Compose a single message using {{name}} and other variables, and add media if needed.

Set a delay

Choose a gap between messages so sending looks natural rather than instant.

Send and monitor

Start the campaign and watch progress as each message goes out.

How to keep results high

Message people who expect to hear from you — consent drives replies and lowers reports

Personalize beyond the name: reference the city, order, or context

Keep the first message short and clear, with one call to action

Start with a smaller batch and grow as your number stays healthy

A note on safety

Any bulk sending carries some risk of a WhatsApp block. Delays, message variation and a clean, opted-in list reduce that risk, but nothing removes it entirely. Our guide on sending without getting banned covers this in depth.

Honest reminder: no tool can promise "100% safe". You stay in control of volume, content and who you contact.
