Two Ways to Execute WhatsApp Marketing:
1. Using unofficial Whatsapp bulk messaging tools
This is where you buy a bulk WhatsApp messaging tool from the market and hook it into the WhatsApp/ WhatsApp business number that you are using on your phone. And send Bulk WhatsApp messages from that number.
Benefits of using unofficial tools
- Most of these unofficial tools give you the option to send bulk messages for free.
- Typically there is no per-message charge.
- You can continue using normal WhatsApp on WhatsApp business along with WhatsApp bulk messaging and marketing from the same number.
- You don’t need to go through any additional verification process by WhatsApp for this.
Limitations of using unofficial tools
- This is really slow and you can only message a limited number of people at a time
- You can send attachments images and personalization but you cannot send button messages or call to action. So in order to reply users have to type the message and send it to you. This reduces the overall number of replies that you get from your marketing campaign
- If you’re messaging unknown people this is what they see on their WhatsApp screen.
And when people report or block your number, WhatsApp might ban your number from their platform temporarily or even permanently. So using the unofficial tools you can only send limited non-promotional types of bulk messages to a limited number of people. - The unofficial tools are not reliable, since no unofficial tool is endorsed by WhatsApp. In fact, they say it’s illegal to use any unofficial tool for unauthorized bulk WhatsApp messaging. They can come up with an algorithm update any day and it can thwart your marketing campaigns.
But what if you want to schedule Marketing and message hundreds or even thousands of people in one go?
That’s where the second option for bulk WhatsApp messaging marketing comes in
2. Bulk WhatsApp messaging with Official cloud API
Here are the steps to execute bulk WhatsApp marketing through the official WhatsApp cloud API
- You go and register and verify your business and a new messaging number on Facebook.
Note: This cannot be the number that you are already using with WhatsApp on WhatsApp for business. - After verification, you connect your WhatsApp official cloud API account with a third-party provider like TeleCRM.
- Upload your template and get it approved by Facebook.
- Then upload your contact list into TeleCRM and send them bulk WhatsApp messages through the Official API.
Benefits of using official WhatsApp API for marketing
- Since it is the official channel, there is no concept of number banning.
