Do you enjoy texting your friends using WhatsApp messenger? Or Do you have a WhatsApp group of your friends or colleagues? If yes, then you know what WhatsApp is. Have you ever wondered how are messages sent to many people in your WhatsApp contact at once with the same or different message with a single click?

The process of sending messages to many people at once with a single click is known as bulk messaging. Let's find out why and how it is done.

Why do bulk messaging?

Lets us consider a scenario, where you need to remind your class group about our class assignment. So, you send the notice in the group chat. What do you think will it happen? That won’t be effective as it will be buried inside tons of messages. Some introverted friends might have muted the group and won’t be notified. Don’t you think it would be better to send each and everyone message regarding the assignment?

In another situation, Suppose you are a merchant who sells utensils and other products. You have the contacts of all your customer saved in your mobile and they all have WhatsApp. Now, this time you have a new product available in your market. You want to notify your customers about the product. So what do you do?

The answer in both cases is bulk messaging using WhatsApp. Here are a few reasons why it is used:

  • Helps in the marketing of the product
  • An easy approach to customers
  • Creating alerts
  • Easier to use 
  • Cost-effective

How to send bulk messages?

Bulk messages can be sent in many different ways. One of the ways is using Microsoft Excel. 

Microsoft Excel is a spreadsheet software available in Windows, macOS, Android, and iOS. It mainly features calculation or computation capabilities, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications (VBA).

In this article, we will step by step learn about how to use MS Excel to send bulk messages to Whatsapp contacts. In this tutorial, we will be using a macro programming language called VBA.

  • Use the following code to program your code

(copy and paste the following)

Sub WhatsAppMsg()
Dim LastRow As Long
Dim i As Integer
Dim strip As String
Dim strPhoneNumber As String
Dim strmessage As String
Dim strPostData As String
Dim IE As Object

LastRow = Range("A" & Rows.Count).End(xlUp).Row
For i = 2 To LastRow
Application.Wait Now() + TimeValue("00:00:01")
strPhoneNumber = Sheets("Sheet1").Cells(i, 1).Value
Application.Wait Now() + TimeValue("00:00:01")
strmessage = Sheets("Sheet1").Cells(i, 2).Value
Application.Wait Now() + TimeValue("00:00:01")
Application.Wait Now() + TimeValue("00:00:01")
strPostData = "whatsapp://send?phone=" & strPhoneNumber
Application.Wait Now() + TimeValue("00:00:01")
Set IE = CreateObject("InternetExplorer.Application")
IE.navigate strPostData
Application.Wait Now() + TimeValue("00:00:05")
SendKeys strmessage
Application.Wait Now() + TimeValue("00:00:10")
SendKeys “~"
Set IE = Nothing
Next i
End Sub

Note: To execute the code correctly.Open whatsapp and be ready to send the message to first contact. 

What this script is doing ?

This script takes data from the first sheets of Excel, where the second row, first column contains phoneNumber and the second row, second column contains messages, then uses a foreach loop to load those information into strPostData one by one and then message is send.
Here you are sending messages without adding to your whatsapp contact list.

  • Click on save
Paste above script and click on Save Icon at top

8 Minimize the VBA window and open the Whatsapp application

9 Insert a button from the developer tab. Rename the button whatever you like Send .

10 Click on send or the button you just made.

11 Click on Allow button if any dialog box opens up.

You may need to click allow as many as the number of contacts you have.

Congrats you have completed the process of sending bulk messages.

This method may seem out of the hand at first. When this system is managed properly and understood well. This method proves to be a good and easy but not efficient way to send bulk messages. However, as the saying goes something is better than nothing, if you have no other resources give it a try.
