Distance learning institutions have become increasingly popular. Currently, they are one of the most interesting options for those looking for better positions in the market.
Online institutions also need to promote marketing to attract students, perhaps even more so, as we are talking about courses taught over the Internet. Among the many digital marketing strategies, knowing how to do WhatsApp marketing is essential.
In 2025, WhatsApp surpassed the 3 billion monthly active users mark worldwide, consolidating its position as the leading messaging app today.
In Brazil, the app is nearly universal among people who own a phone. The country has 185 million people connected to the internet, according to the Digital 2026: Brazil report, and WhatsApp usually appears as the most used messenger in that group.
This massive reach makes WhatsApp an indispensable tool for both personal communication and business strategies in various sectors.
What changed since institutions first adopted the channel is the price of sending, and that is where this article starts.
Why did WhatsApp become central to marketing strategies?
Forget WhatsApp as you knew it. Nowadays, it is not just a messaging app, it is an extremely useful tool for your digital marketing strategy, with conversation history, catalog, automation and CRM integration.

WhatsApp marketing can benefit your institution in different ways, but always revolves around the following objectives:
- Attract new students
- Create and strengthen relationships, which sustains student retention
- Establish authority
One regulatory note matters for institutions delivering at a distance in Brazil. Since 2025, part of the portfolio moved to a blended format, and communication has to say so: an enrollment campaign promising full flexibility for a program that gained in-person workload produces enrollment that will not hold.
How much does a WhatsApp campaign cost under per-message pricing?
Since July 1, 2025, Meta deprecated conversation-based pricing and started charging per message sent through the official API. Budget stopped being a function of the 24-hour window and became a function of send volume, which changes the math of any WhatsApp campaign.
The message category sets the price, and the same information can cost a lot or nothing depending on how it is sent. Here is how the platform organizes these types:
|
Category |
What it is for |
Typical use at an institution |
|
Marketing |
Generate awareness and drive sales |
Opening of applications, reengaging a stalled lead |
|
Utility |
Follow up on a user action or request |
Application confirmation, exam reminder, enrollment status |
|
Authentication |
Send a one-time passcode |
Access to the student portal |
|
Service |
Answer a question the user started |
Candidate support; free since November 2024 |
Table: Message categories on the official platform and the matching use in a recruitment operation.
The practical reading of that table is a budget rule. Every conversation the institution can pull into the service category, by answering whoever reached out first, costs nothing, and every sequence that fires in bulk lands in the most expensive category.
That is why click-to-WhatsApp ads and a direct link on the website beat a purchased list. They make the candidate start the conversation, and the institution replies inside the free window.
The planning effect is direct. Enrollment campaigns once designed by number of sends are now designed by the objective of each message, because every send carries its own price.
Why have a number dedicated to WhatsApp Business?
On WhatsApp you need to be connected to a cell phone number. Therefore, it is interesting to have a number dedicated to WhatsApp Business, which will be used exclusively to communicate with students, also separating it from your personal account.
This will be the number you display on the institution's website and in social media, informing students that they can get in touch via WhatsApp.
The choice between the WhatsApp Business app and the official API sets the ceiling of the operation. The app handles the volume of a small admissions desk; the API supports marketing campaigns with segmented sending, multiple agents and CRM records.
One detail usually slips by. A recruiter's personal number takes the candidate's history away when that person leaves the institution, and the professional account is what prevents it.
How does real-time support help attract and retain students?
In marketing, it is difficult to make statements and establish something as absolute truth, as things change quickly, but very quickly. But if there's one thing that doesn't change in the world, it's the importance of good service.
Email service, for example, is still widely used, but it is not as effective as WhatsApp service. Being served in real time, politely and having all doubts resolved wins the heart of any customer.
In addition to almost immediate responses, with WhatsApp Marketing you can offer exclusive treatment, such as creating a chatbot, which also increases retention and, above all, increases the chances of attracting new students.
This is the point where attract students and retain students stop being two operations. The same channel that answers a question about the application also announces re-enrollment later, and the conversation history stays with the person.
In practice, student recruitment gains a channel with memory. The advisor who handles the second message knows what was said in the first, and the candidate does not have to tell the story again.
What content should a WhatsApp message campaign carry?
What do you do after creating a contact list? The answer decides whether the WhatsApp message campaign becomes a relationship or a block, because in the app the cost of annoying someone is immediate.
Open rates on WhatsApp are often cited at close to 98%, far above what other channels show, and they are a market figure rather than a platform audit. The comparison with average social media engagement, around 0.06%, helps size the difference in attention.
If you have a blog on the institution's website and feed it based on content marketing, you can send links to new articles to your contact list. If you work with ebooks to attract leads, you can also send them via WhatsApp.
The selection rule is simple: only what the student would use even if the institution were not the sender belongs in the sequence. Deadlines, results, study material and concrete opportunities pass that test, and institutional announcements do not.
What does an AI SDR agent solve in WhatsApp campaigns?
To boost your WhatsApp Marketing campaigns, consider using automation and personalization tools. Integrating chatbots and using segmented messages allows for faster and more effective customer service, as well as providing a personalized experience for the user, increasing the chances of conversion.
The step after the menu chatbot is the AI SDR agent, which talks in natural language, qualifies by the institution's criteria and escalates to the human team only what is ready. During the application peak, it stops a Saturday night question from being answered on Monday.
The difference shows up in the record. An AI SDR agent connected to the CRM returns declared intent, program of interest and funnel stage, which feeds the next marketing campaigns with data instead of guesswork.
Automation does not replace editorial judgment. A well-trained agent on an outdated portfolio only fails faster, which is why the message sequence has to be reviewed every enrollment cycle.
Which metrics prove the return of a WhatsApp engagement campaign?
Monitoring the performance of your campaigns is crucial to success in WhatsApp Marketing. Metrics such as open rate, response rate, conversion rate, and user feedback provide valuable insights into the effectiveness of your strategies, allowing you to make real-time adjustments to optimize results.
With per-message pricing, a new metric entered the equation: cost per message sent by category. A WhatsApp engagement campaign that doubles volume without moving the response rate simply became twice as expensive for the same result.
The indicator that closes the account is still enrollment. Tracking educational marketing metrics by program, and not only the channel total, avoids concentrating budget where volume is high and conversion is low.
It is also worth measuring block and opt-out rates. That is the most honest sign that the sequence went too far, and it shows up before conversion drops.
A single dashboard for recruitment and retention avoids the most common misreading of the channel. Without separating enrollment campaigns from communication with active students, the average rate hides both realities.
Frequently asked questions about how to do WhatsApp marketing
Where to start your first WhatsApp campaign?
Start with the cheapest part: organizing the inbound side. A dedicated WhatsApp Business number, a channel link on the website and in ads, and a fast reply to whoever writes first already deliver most of the result with no sending cost.
Then comes the proactive sequence, and there the message category becomes a budget decision. Knowing how to do WhatsApp marketing today means knowing which category fits each objective.
This is where educational marketing strategies stop being creative work and become operations: who sends, how often, to whom and with which declared objective. It is the same discipline behind student recruitment and retention in any channel.
If your institution wants to structure these marketing strategies in the channel and connect WhatsApp to the CRM, talk to the Mkt4edu team and start with the sequence design before the first send.
