Making it official! SleekFlow is a WhatsApp Business Solution Provider.

The concept of Broadcast Messaging is not new nor difficult to understand, it is simply the desire to get an automated message out to a large group of people in the shortest amount of time. Marketers will no doubt think of using it for promotional messages and consumers will immediately think of receiving an avalanche of congratulatory messages from friends and family over the holidays. While true, the broadcast function can also be used for other purposes as well, such as sending severe automatic weather alerts or alerting the public of emergencies. For businesses, the best application is for WhatsApp marketing messages and campaigns.

As messages provide a more personal touch and are more instant than emails, many marketing and customer service teams have begun to include bulk broadcast messages into their social & marketing messaging strategy in recent years.

What is WhatsApp Broadcast?

Reaching the largest number of people in the shortest amount of time is no doubt important, but the key lies in ensuring that the recipients receive the automatic message through a reliable platform. When governments and public organizations need to notify the public urgently, messages are usually relayed by SMS through the major network providers. However, when it comes to promotional marketing, the focus and methods are different.

The logic behind the message blast  

When choosing the right service provider, apart from taking the price of the target audience’s commonly used platform into consideration, the sender should also be aware of whether did the supplier provide:

  1. Encryption tools that can be used to deal with the privacy issue

  2. Analytical features that allow you to evaluate the performance

Lacking an efficient system to store and analyze valuable information such as customer response rate and blog comments will ruin your chance of generating more sales.

Other than the number of broadcasting messages, you also need to consider:

  1. Size of the database used to store information of your contacts

  2. Structure and size of the content of your message

  3. Archive capacity  

Once you have chosen your service provider, the first thing is to upload your contact database to your supplier’s platform. Therefore, convenience is also a vital factor as I bet you would never want to waste your time on entering your client’s contacts one by one.

What are the features of WhatsApp Business Broadcast by WhatsApp Business App?

With more than two billion WhatsApp users around the world, it is no doubt that WhatsApp also ranks amongst one of the most popular sales channels. Apart from the huge user base, here are 3 simple reasons why you (and your boss) should start converting customers on WhatsApp:

With such ingrained habits, WhatsApp can better close the distance between businesses and customers. This is because WhatsApp messages are better integrated into customers’ lives and habits than older communication channels such as email and SMS. Therefore, businesses stand a better chance at attracting attention and increasing customer engagement and eventually, conversion, sending broadcast on WhatsApp with messages and conversations. WhatsApp Broadcast automations are the ultimate trick to your marketing strategy!

“Another feature I found quite impressive is the WhatsApp broadcasting function. Many of our clients are heavy WhatsApp users. It’s easier to build trust and relationships with them via WhatsApp. Traditional phone calls take way too much time while SMS blast is more like a one-time thing instead of a chatroom.”

Small businesses can get started quickly with the free WhatsApp Business App for more familiarity as it has the same user interface as the regular WhatsApp App. This way, they can discover the advantages to broadcast on WhatsApp, send automated broadcast messages and experience their benefits to their business.

However, there are a couple of features that set the WhatsApp Business App apart:

1. Verified Business Profile

Provides key business information such as your address, business description, email address, and website.

2. Labels

Allows you to organize your contacts or chats with labels, so you can easily find them again. Read on to see how should you make good use of labels.

3. Quick replies

Save and reuse messages you frequently send so that you can easily answer common questions in no time.

4. Create a catalog of products and services for easy browsing

WhatsApp Business interface and broadcast messages features

Although the WhatsApp Business version has more features than the regular version, when it comes to handling conversations, each business account only allows a single user to log into the app to reply to customers. Even if you use WhatsApp Web simultaneously, businesses can only reply to a maximum of two customers at the same time. That’s not all - any additional or even accidental logins, will log out existing users, resulting in loss of unsent messages and workflow bottlenecks.

As such, larger corporations should not just stop at the WhatsApp Business App, but instead, seek out omnichannel messaging platforms to streamline their messaging workflow and send bulk WhatsApp messages for promotional purposes.

How to send broadcast messages by WhatsApp Business App?

If you are operating a small business with one or two staff members to answer your customers’ queries, you can begin to broadcast on WhatsApp using the WhatsApp Business App’s limited broadcast function.

1. Create a WhatsApp broadcast list

The advantage of creating a Broadcast WhatsApp List is that you can finely segment your customers and create an unlimited amount of Broadcast Lists.

That being said, do note that each list can only have a maximum of 256 people added to it. By segmenting your customers into WhatsApp broadcast lists, you can send a message to up to 256 people at once, and the recipients will receive a broadcast message that looks like a personal message from you right in their conversation log with you. However, we strongly recommend that you do not send a large number of messages at once as it might result in your account being blocked.

How to create a WhatsApp Broadcast list:

  • Tap on “Broadcast List”

  • Tap on “New List”

  • Select the customers that you want to add to the list

2. Using WhatsApp Labels

WhatsApp chat labels for broadcast lists

Adding labels is a great way to segment your customers in WhatsApp. The best part about WhatsApp’s labels is that they can also be added to individual message bubbles. For example, you can add labels to all positive reviews and view all of them at the same time. This way, you will be able to easily screenshot the reviews and share them on social media! Apart from that, you can also label suggestions from customers and review them all at once to make improvements.

You can also create WhatsApp broadcast lists for specific customers using labels. For example, you can label all customers who have given your business a positive review and add them to a broadcast list to send them a thank you offer. In addition, you can also add labels to customers who have not paid and send them a payment reminder!

Step-by-step: creating broadcast lists from Labels (Android)

  • Tap on More Options 

  • Select Labels

  • Choose the Label you want to create a Broadcast List with

  • Tap on More Options and send Broadcast to customers

  • Select the green tick on the bottom right of the page and start drafting your message

Limitations of WhatsApp Business App to broadcast messages

Apart from the WhatsApp Broadcast function, you can also forward automated messages on the WhatsApp Business App. However, each message needs to be forwarded individually. Just think about the hassle!

  1. WhatsApp Business’s Forward function, also known as WhatsApp Broadcast only allows you to forward a message to up to 5 recipients at any one time. Think about the number of times you’ll need to repeat this copy and paste action for 500 customers!

  2. Next, what if you have a thousand or even ten thousand customers? (P.S. You’ll need to manually add each contact individually before being able to forward a message to them)

  3. Last but not least, spare a thought for your employees who might start steering clear of WhatsApp and stop replying to your WhatsApp Broadcast messages.

Although this article mentioned the Broadcast Lists function above, keep in mind that messages can only be broadcasted to a maximum of 256 people in one go. What happens when the number of customers increases? (OS: This should be a happy problem… shouldn’t it?)

In addition, with the WhatsApp Broadcast function, everyone in your Broadcast List receives the exact, same, message. Thus, if you want to personalize your message a little by including their names, good luck on sending out the personalized texts one by one.

If you think about it, the biggest problem with the WhatsApp broadcast list function is not the cap on the number of people, but the fact that you cannot broadcast a message to someone who isn’t in your contacts. What a bummer.

That’s not all, when you try to broadcast on WhatsApp, you risk being reported by customers and blocked by WhatsApp, leaving you uncontactable. This not only results in tons of lost leads but also gives your customers and potential leads a negative impression of your business.

Larger businesses can’t just stop at the WhatsApp Business App, they need a complementary omnichannel platform.

Solution: send WhatsApp Broadcast messages with API

While there are many limitations to WhatsApp Business Broadcast, there is, in fact, one simple solution - WhatsApp Business API.

To expand your business and communicate with customers more effectively, you’ll need to understand the WhatsApp Business API (Application Programming Interface) and how its practical functions work differently when broadcasting campaigns are created. This would enable your team to send WhatsApp marketing messages to clients in the most efficient way.

1. Test your campaign messages

You can send yourself a test message to ensure that the automated message content is showing up correctly before you broadcast it to your customers.

2. Broadcast messages at scale

When using the Official WhatsApp Business API, you can send up to 1000 messages a day by default. However, if you send more than 2000 messages within the first week, you can then increase your daily messaging limit to 10,000 messages per day with WhatsApp’s approval. By using SleekFlow’s campaign feature, you’ll not only be able to cut down on human error when copying, pasting, and editing messages but also save tons of time!

However, do note that before you broadcast automated messages using the campaign feature, you need to register your message and send it to WhatsApp for approval. This message is called a template message and if you don’t know how to get started, our SleekFlow team will be happy to help!

WhatsApp Business Template Messages

WhatsApp Template Messages, as mentioned previously, are pre-approved message templates used for WhatsApp broadcasting.

Template Messages are often utilized for:

  • Marketing: promotional offers, product announcements, discount codes, and more

  • One-time passwords: codes for users to secure their accounts

  • Transactional messages: account or order updates, order delivery alerts, meeting reminders etc.

They are also used when it has been more than 24 hours have elapsed since the user’s last response to you as any other types of messages sent outside the 24-hour window will fail to reach the user.

For WhatsApp to approve your customized Template Messages, certain rules must be followed. The correct format for each type of information inserted in the message is as follows:

  • Name: A message template name can only contain lowercase alphanumeric characters and underscores. No other characters or spaces are allowed.

  • Type: Select the appropriate template type from the drop-down list. The template type must fall under one of the template type options, e.g. appointment update, issue resolution, payment update, etc.

  • Translations: All message template translations must be provided by you in the format below. The element name will be the same for all translations. When sending a message template from the WhatsApp Business API, you will specify the language you would like the message template to be displayed in by using the language field.

  • Variables: The correct format for variables is this string: {{#}}, where # represents the variable index. Note: variables must begin at {{1}}.

Each Template Message sent to WhatsApp for approval usually takes around 1 to 2 days. If you're wondering why your WhatsApp message template was rejected, check for:

  • Typos or grammatical errors

  • Misformatting of variable parameters (make sure the format is {{1}} as mentioned above), or contain special characters (i.e. #,$,%).

  • The selected language corresponds to the language in the content.

  • Submission format for testing API connection follows: Message template name: test / Content: Hello {{1}}

  • Shortened URL for your links or including URLs that do not belong to your business.

  • Message templates violate WhatsApp's Commerce Policy or WhatsApp's Business Policy

To ensure that you get the green light quickly and start blasting as soon as possible, the best thing to do is to work with a WhatsApp Business Solution Provider (BSP), like SleekFlow!
