WhatsApp blast messages for business: how to send and get the best out of them

WhatsApp blast for businesses

Imagine that you own a retail store and would like to promote a limited-time flash sale on your products. How would you let your customers know of this promotion? Sending out messages one by one would be time-consuming, so this is where blasting messages come in. 

With over 2 billion active WhatsApp users worldwide, WhatsApp blaster services allow you to reach a large audience quickly and easily.

What is WhatsApp blast?

WhatsApp Business interface and broadcast messages features

WhatsApp blast is a feature of WhatsApp Business API, enabling you to send a single message to numerous recipients simultaneously. This is ideal for businesses needing to disseminate information, deals, news, or updates swiftly. However, ensure compliance with WhatsApp's guidelines and respect user privacy to avoid being marked as spam.

Benefits of WhatsApp blast messages

1. Instant and direct communication 

69% of internet users use phones to do product research online, and 89% of users prefer texting a business over any other communication channels. WhatsApp blasts deliver messages directly to recipients' smartphones, ensuring prompt visibility. Unlike emails or social media posts, WhatsApp messages are less likely to be ignored.

2. High open and engagement rates

The average open rate of WhatsApp messages is 98% which is higher than other forms of digital communication. With notifications enabled, users are constantly alerted to new messages, leading to higher engagement rates. Interactive tools such as chat buttons enhance this further.

One of our key findings is that people prefer to read messages on WhatsApp. After using SleekFlow, we observe a dramatic increase of 40% in open rate in our communications.

3. Cost-effective marketing strategy

Utilizing WhatsApp for marketing incurs minimal costs. While the WhatsApp Business API may have associated costs, it eliminates the expenses of traditional marketing methods like print ads. Small businesses can opt for the free WhatsApp Business app, though it has limitations on contact numbers.

Crafting effective WhatsApp blast messages

  1. Identifying your target audience: Tailor your message to engage your audience. Understand their interests, needs, and preferences to craft relevant content.

  2. Personalize and customize: Personalization increases engagement. Address recipients by name and segment your audience based on interests, demographics, or location.

  3. Create engaging and action-oriented messages: Capture attention with catchy phrases and concise content. Use strong calls-to-action (CTAs) like "Shop Now" or "Register Today."

  4. Utilize media: Enhance messages with images, videos, and GIFs to make your content more appealing and informative.

  5. Incorporating strong Call-to-Action (CTA): Tell people what you want them to do after reading your message. Whether it's to buy something, sign up for an event, or visit a website, make it clear what step you want them to take.

How to measure the success of your WhatsApp blast message campaigns

Analytics example from SleekFlow omnichannel platform for WhatsApp marketing

1. Tracking key metrics - delivery, open, and click-through rates 

To see how well your WhatsApp blast is doing, you can track important numbers to help you understand how effective your message was. 

Here are the different types of metrics you should keep track of:

  • Delivery rate: Shows how many messages reached people. 

  • Open rate: Tells you how many people actually opened your message. 

  • Click-through rate: Measures how many people clicked on the links or did what you asked in the message. 

2. A/B testing and optimizing WhatsApp blast campaigns 

A/B testing is a method of trying two different things to see which one works better. You test them with a small group and then use the better one for a large group. It helps you learn what people like more.

Below are the steps for A/B testing:

  • Create variations: Make two different versions of your message, trying out different words or pictures.

  • Test with small groups: Send one version to a small group and the other to another small group.

  • Compare results: See which version gets a better response such as more clicks or likes.

  • Choose the better one: Pick the version that worked better.

  • Show to more people: Send the better version to a larger group.

  • Learn what works: Understand why the better version was liked more.

  • Try different times: Send messages at different times to find when people react the most.

  • Improve your plan: Use what you learned to make your messages and timing even better.

3. Leveraging analytics to improve future campaigns

After you've sent out your WhatsApp blast message campaign, take a close look at the numbers and learn from them. These numbers help guide you to make better messages in the future.

Here are some suggestions:

  • If the open rate is low, consider spicing up the subject line to make it more captivating.

  • If the click-through rate is low, you might need to make your message clearer or more exciting to catch their interest. You can also provide incentives such as discount codes or free trial packages to motivate actions.
