Best Practices for Using WhatsApp Blast Messages

When sending blast messages, it's crucial to follow best practices to ensure your communications are effective and well-received. Customer Success Manager, Elva Tan recommends businesses follow these best practices:

Respect Privacy and Consent

“Take the time to understand the WhatsApp Business Business Messaging Policy before blasting WhatsApp messages. For example, always ensure that you get a customer’s consent before messaging them.”

“From my experience, many businesses get banned for blasting WhatsApp messages because they didn’t get opt-ins before messaging customers. There’s a high risk of customers reporting your messages as spam if you’re blasting WhatsApp messages without this consent,” said Elva Tan.

By complying with these rules, you can maintain a positive reputation and avoid being flagged as spam.

Review Performance and Experiment

There’s always an opportunity to improve on the performance of your blast messages. Elva adds that customers that have great success with blast messages tend to experiment with the content of the messages to maximize their performance.

Use Visual Content

Enhance your messages with images or videos to make them more engaging. Visual content can help capture the recipient’s attention and convey information more effectively. In fact, it can generate 650% higher engagement compared to text-only content.

Send Personalized and Concise Messages

Even though WhatsApp blast messages are sent to multiple recipients, personalize them where possible. On, you can do this by using variables. For example, if you want to include the first name of every customer in your message, you can use the $ variable.


How Can I Create Message Templates?

On, you can create Message Templates by going to Settings > Channels > Manage the WhatsApp API account > Templates.

When Should I Obtain Customer Opt-Ins?

You must obtain opt-ins from recipients before blasting WhatsApp messages. If you fail to obtain recipient opt-in, your number might be reported as spam and is at risk of being banned by WhatsApp

Are There Any Limits on the Number of Messages That Can Be Sent?

If you are on the WhatsApp Business App, you are limited to sending 256 contacts in each broadcast list. If you are using WhatsApp API, the number of contacts you can message depends on the messaging limit of your number. Increase your messaging limit by improving the quality rating of your number.

You now know everything about sending a WhatsApp blast message. It is a powerful tool for businesses looking to market and promote your products with a large audience quickly and efficiently.
