Everybody talks about WhatsApp automation—us, Landbotters, included. 

But how does that translate into practice? What does it take to automate customer communication via one of the most popular messaging apps? What kinds of results can you derive from WhatsApp Business API adoption?

To give you a better insight into this automation strategy, we prepared this step-by-step tutorial to develop an automated WhatsApp messaging campaign using Landbot, Airtable, WhatsApp, and Make. A campaign that took us from a 5% to 25% engagement rate in a blink of an eye. 

Engaging PQLs: From Email to WhatsApp


One of the main sources of PQLs (Product Qualified Leads) for our sales team was email-powered outreach to Landbot users in the free plans who perform certain key actions that indicate that they are interested in becoming a customer. These tasks were an indicator they needed help from our sales team. So, once they triggered the assigned actions, we sent them an email suggesting they book a call with a Landbot expert so we can help guide them on their way.

However, we realized that this strategy had a problem—the contact channel. 

The contact channel was not fulfilling our needs as it is too saturated and people often overlook emails or simply do not pay attention. 

Why Choose WhatsApp Instead?

The moment we realized that email was not the best channel to reach these users, we started looking for alternatives and found the solution in our own product, sending those campaigns by WA instead of by email.

The open rate in all the experiments that we had run on WhatsApp before was always around 90% and that was what we needed—a good open rate combined with an easy response mechanism.

This way, apart from trying to increase the volume of PQLs for the sales team, it was an opportunity to validate the Landbot WhastApp solution for use cases more related to sales.

WhatsApp Automation for No-Coders

Since we were already planning to use this as a use case if things panned out, we wanted to make it as actionable and shareable as possible. Hence, we decided to build the automation flow with no-code tools throughout: Landbot, Make, and Airtable

What did we need to get this experiment done?

  • Users’ consent to receiving messages through WhatsApp and their phone number. This was very easy since we had both the consent and the number as a courtesy of the Landbot onboarding process.
  • A platform from which to send the messages. Landbot.
  • A tool from where the SDRs can work through the leads and send the messages to users they deem qualified. We used Airtable since it gave us the possibility of using trigger buttons.
  • A tool to connect the Airtable with Landbot to send the message. We opted for Make since it is free and everyone could use it.

How to Build the No-Code WhatsApp Automation Process

To save you some reading time, here we have a great step-by-step video on how to send WhatsApp messages combining Landbot, Make, and Airtable:

Experiment Results 

At the Sales level

At the Sales level, the results have been very positive. We have gone from a 5% engagement rate to more than 25%. Moreover, the old response time of more than a day was reduced to less than 4 hours.

Apart from gaining more and happier clients, we are really recruiting and demoing the product at the same time as they got to see in action what they were buying. And of course, it has been a motivation for the SDRs, since this new process is significantly less frustrating.

At Product Level

Through this experiment, we confirmed WhatsApp to be one of the best communication channels out there right now as well as validated the hypothesis that people do not leave unread messages in the WhatsApp inbox.

Next, we also validated that templates using the buttons feature work much better than with raw text.

It’s clear that the integration of these three tools gives you infinite possibilities so that the marketing and sales teams face very few limits and friction points. 

Who knows, our next experiment might be to use WhatsApp as a support tool...

Frequently Asked Questions about Landbot Pricing

What’s a Landbot chatbot template?

There are three ways to go about building a conversational app with Landbot:

1 - Do it all from scratch but still without coding

2 - Use only a few pre-made elements (bricks)

3 - Pick and customize a pre-designed template


There’s no need to reinvent a flow if our conversational experience designers already built a chatbot template for your use case. Before committing to a free sign up or a specific template, you can always use the preview function to try out the end-user experience. When you do load your chosen template, you’ll see the conversational flow all set up for you with guiding notes when needed.

All you have to do is customize the content inside the flow that’s already there. Edit the text, images, gifs, and links in the blocks so they fit your brand and product!

What’s the difference between a chat, a WhatsApp chat, and an AI chat?
  • A chat in Landbot represents a structured conversation between your bot and an end user, following a rule-based flow for web chatbots. It guides the user through specific tasks using buttons, keyword triggers, and decision trees with predetermined responses.

  • A WhatsApp chat in Landbot is a conversation between your bot and an end user on WhatsApp, following Meta’s messaging rules. When an end user messages your bot, a 24-hour window opens, allowing free responses, and the interaction counts as a WhatsApp chat in your Landbot plan. After 24 hours of inactivity, only pre-approved Message Templates can be sent, which you can manage directly in the Landbot platform.

  • AI chats incorporate AI functionalities, leveraging Landbot’s AI feature blocks or AI Assistants for lead generation, FAQs, or appointment booking. This enables the bot to understand intent and provide personalized, real-time responses instead of relying solely on predefined flows. AI chats are tracked and billed separately from regular chats and WhatsApp chats.

What is considered a “seat” in a Landbot plan?

A seat refers to a user license that grants an individual access to the Landbot platform under a specific account. Each seat allows one team member to log in, build, manage, and collaborate on chatbots.

How many chats are included in the Business Plan?

Our Business Plan is fully customizable to suit your needs, including the number of chats, seats, and WhatsApp Business Account numbers. Please reach out to our Sales team for a personalized quote tailored to your requirements.

What happens when I reach my plan's chats limit?

If you go over your paid plan’s chat limit, extra chats will be charged based on the chat type. Regular chats cost €0.05 per extra chat, while WhatsApp chats also cost €0.05 per chat plus Meta’s additional fee. AI chats are €0.10 per extra chat. Business plans have custom pricing for extra chats.

Are there any plans that only include WhatsApp?

No, all of our plans that include WhatsApp (WhatsApp Starter, WhatsApp Pro, and Business) also grant access to other channels, such as web, API, and Facebook Messenger. These additional channels are included in all WhatsApp plans.

Can I add more than one WhatsApp number to my account?

Yes, you can link multiple WhatsApp Business Account numbers to your Landbot account, but the number of WhatsApp Business Account numbers allowed depends on your plan.

What payment methods does Landbot accept?

Does Landbot use the official WhatsApp Business API? How does the application process work?

Yes! Landbot uses WhatsApp’s official API to integrate the most popular instant messaging app. The API offered by Facebook(Meta) is under constant improvement, the reliability is fantastic and generates a frictionless experience for your users and for your team. To review which type of enterprises, businesses and brands WhatsApp accepts at the moment, please read our WhatsApp API application guide.

Landbot’s onboarding team helps you in the application process. Once you sign up for Landbot’s WhatsApp solution, our team will ask you to submit the required information and initiate the application process on your behalf. The entire process usually lasts around 1-2 weeks, regardless of which provider you work with. We take utmost care to ensure each business we collaborate with has their application approved, managing the application process at every step of the way. However, ultimately, the final approval decision rests with WhatsApp.

Can I start building my bot before my WhatsApp API access is approved?

Landbot’s special WhatsApp Test environment feature allows you to build and test your WhatsApp bot before your API application gets approved.

This is possible because the testing channel is a closed one, and only allows communication between the Landbot interface and the phone number you associated with the test account. So you can already test your WhatsApp bot with your own phone, and have it ready to be published live to your users when the access is approved by WhatsApp.

Do you offer support resources on WhatsApp bot creation?

Yes, you have access to a large collection of support resources including WhatsApp guides, documentation and academy videos to help you get the most out of the WhatsApp chatbot builder and campaign manager. Listed below are some of the resources:
