How to set up and send WhatsApp Newsletters

Traditional marketing channels like email are becoming more and more saturated. Consumers receive at least 10 newsletters every day and they delete most of them without reading.
Why? Because of channel fatigue. Channel fatigue occurs when your audience gets so many marketing messages on a specific channel that they get overwhelmed by them and stop paying attention. And as you know, all of our email inboxes are bombarded by too many newsletters every day.
As a marketer, this leaves you with two options:
- Keep optimizing your emails, hoping your opening rates will go up by 1% or 2%
- Switch to a channel where there is no competition yet, such as WhatsApp
In this article, we’ll discuss why you should go for option two: the WhatsApp newsletter. We’ll explain what it is and how you can send them.
What is a WhatsApp newsletter?
WhatsApp newsletters are paid bulk messages via WhatsApp to share relevant and valuable information with customers. WhatsApp is on the rise as an important new channel for marketers. With over 2 billion active users worldwide, it’s safe to say your customers are on there. And you know how the saying goes: always go where your customers are.

The benefits of sending newsletters on WhatsApp
There are multiple benefits to sending newsletters via WhatsApp.
First of all, WhatsApp is the most popular messaging app in the world. Currently, it has over 2.4 billion active users worldwide. Aside from using WhatsApp to talk to friends and family, people are now also using it to communicate with businesses. “Go where your customers are” is a fundamental marketing rule, and the numbers don’t lie.

Besides that, WhatsApp has way higher opening rates than email. With all our inboxes being flooded by newsletters every day, email newsletter fatigue is growing. According to research from Gartner, WhatsApp messages have an average opening rate of 90%+, while email has an average opening rate of 22%.

Sending newsletters on the WhatsApp Business app vs the WhatsApp Business API
You can send WhatsApp newsletters via WhatsApp’s broadcast feature. This feature comes in all of WhatsApp’s products, but as a business, you can only use the following options:
❌ Regular WhatsApp
✅ WhatsApp Business
✅ WhatsApp Business API
The WhatsApp Business app was created for small businesses with low message volumes. It can only be used by four users at the same time. The app is free of charge, but can only send a maximum of 256 newsletters a day. More importantly, the app has no guaranteed data protection.
The WhatsApp Business API was created for medium and large-sized businesses. It enables businesses to manage WhatsApp Business with multiple users, automate repetitive workflows, get in-depth insights into performance and customer happiness, and send out 800 newsletters a day. The API does not come with its own interface, and can therefore only be accessed via a customer engagement platform such as Trengo.
From here on out, we’ll discuss how to send WhatsApp newsletters with the WhatsApp Business API.
Why you need pre-approved template messages
You can use the broadcasting feature to send WhatsApp newsletters to your customers. However, to prevent spam, outbound messages can only be sent by using template messages. These templates have to be approved by WhatsApp before you can send them out. When you use the API via a WhatsApp Business Solution Provider such as Trengo, the approval process is fast and smooth and can be done within minutes.
Here is an example of what a WhatsApp Business newsletter template looks like:
Hey [1],
We are excited about the new rollout of our family of products and as part of our launch, we will be discounting the whole line of products on [2] for all of our VIP customers.
We are looking forward to seeing you at our VIP event!
Cheers,
[3]
You can personalize your WhatsApp newsletters with variables. The numbers between brackets are variables for the following:
- [1] is the variable for your customer’s name
- [2] is the variable for the date your business will run the promotional offer for your customers
- [3] is the person’s name and title or department that’s sending the message.

Message limit for WhatsApp newsletters
Pre-approved templates aren’t the only measure WhatsApp takes to avoid spam. Another is that you can only send WhatsApp newsletters to a limited number of customers a day.
If you decide to choose Trengo to use the WhatsApp Business API, you can send out 800 WhatsApp newsletters a day. You don’t have to send all 800 at once, you can spread this out as you see fit (i.e. two audiences of 400 customers).
WhatsApp newsletter costs: an overview
Last but not least, you’ll need to set aside some budget. Because sending WhatsApp newsletters is very cheap, but it’s not free.
WhatsApp newsletters are what WhatsApp calls ‘business-initiated messages’. Below, you can see how much that costs you per newsletter. If your country is not on the list, check out the pricing list for all countries.

Note: the first 1000 conversations every month (both user and business-initiated) are completely free of charge.

How to get a sign-up for your WhatsApp newsletter
You now know how to set up and send a newsletter on WhatsApp, but how do you get people to sign up?
There are multiple options:
- An online sign-up form (make sure to ask for their phone number)
- A WhatsApp link (which sends your customer to a WhatsApp conversation in which they can sign up)
- A QR code
At Trengo, we organize an event called WhatsApp Commerce. To gather sign-ups, we sent out physical cards with the following QR code (go ahead and try it yourself ;-)

How to get an opt-in for your WhatsApp Business newsletter
Just as with email, you need to ask for customers to opt in to your WhatsApp Business newsletter. As we said earlier, WhatsApp wants to prevent spam on its platform. By collecting opt-ins, you prevent getting reported as spam too many times.
You are free to come up with your own method to collect these opt-ins. There is no formal way of doing this. Possibly the easiest way to do it, however, is by using buttons.
For our WhatsApp Commerce event, we also needed to create an opt-in for attendees. We did this with an automated message. After scanning the QR code, attendees only had to hit send.

WhatsApp newsletter templates per use case
Now that you know how to technically set up a WhatsApp newsletter, it’s time to get to what it’s all about: the creative. At the end of the day, no matter the channel you’re using, it’s all about what you’re saying.
