Messaging students on WhatsApp: what the research says actually works

Your students already read their messages. Whether they act on yours comes down to the sender, the timing and the reply.

In Saudi Arabia, WhatsApp is the most used platform online. Its usage rate is 92.7%, ahead of Snapchat at 83.6% and TikTok at 77% (CST, Saudi Internet 2025).

So the question isn’t whether students will see a university message on WhatsApp. It’s whether they’ll act on it.

That’s where the research gets useful. Some messaging programs moved real outcomes. Others reached hundreds of thousands of students and changed nothing.

The channel was the same. The difference was everything around it.

Where students’ attention is

In the Gulf, being online is close to universal.

  • Saudi Arabia’s internet penetration reached 99.6%. And 61.3% of users spend at least seven hours online a day (CST, Saudi Internet 2025).
  • In the UAE, internet penetration is 99.0%, with 23.0 million mobile connections. That’s about two for every resident (DataReportal, Digital 2026).

WhatsApp holds that attention. Worldwide, its users spend about 59 minutes a day in the Android app alone (DataReportal, Digital 2026).

These are national and global figures for all ages, not student surveys. Student research points the same way. In a survey of medical students at two Saudi universities, nearly all used WhatsApp. More than half already used it for academic work (Medical Teacher, 2018).

Many students already run study groups and class questions on WhatsApp. Usually without the university in the thread. That’s how fragmented communication starts.

The channel works. Blasts don’t.

The strongest evidence on messaging students comes from randomized trials. Three findings stand out.

Personal and timely works. Castleman and Page texted first-year students personalized reminders to renew their financial aid. At community colleges, students who got the texts were almost 14 percentage points more likely to stay enrolled through spring of their second year (Castleman and Page, Journal of Human Resources, 2016, U.S. data). At four-year universities, where persistence was already high, the texts made no difference.

Generic at scale doesn’t. Later trials sent similar nudges to more than 800,000 students through national and state campaigns. The researchers found no effect on enrollment (Bird and colleagues, Journal of Economic Behavior and Organization, 2021, U.S. data).

A human makes the difference. During school closures in Botswana, researchers compared text messages alone with texts plus a short weekly phone call. Texts alone had no significant effect on learning. Texts plus a call raised numeracy scores by 0.12 standard deviations (Angrist, Bergman and Matsheng, Nature Human Behaviour, 2022).

The lesson is simple. The channel gets your message seen. The sender, the timing and the person behind it get a result. It’s the same pattern behind summer melt.

What “WhatsApp-first” should mean

WhatsApp-first isn’t about sending more. It’s about sending better.

  • Ask first. Get opt-in at application or registration. Say what you’ll message about. Honor opt-outs straight away.
  • Use one official number. Students should know it’s really their university. Not a staff member’s personal phone.
  • Make one clear ask per message. Pay the fee. Upload the document. Book the advising slot. A button beats a paragraph.
  • Time it to the student. A reminder three days before their deadline lands. A Monday broadcast to everyone doesn’t.
  • Put a person behind the thread. When a student replies “I’m not sure I can come”, someone with a name should answer.
  • Use their language. Arabic or English, chosen by the student.
  • Count replies and actions. Sent is a cost. Done is a result.

Where Eduway fits

Eduway runs student and family engagement on WhatsApp, on Meta’s official platform. Students opt in first. Every journey sends from one institutional number, in Arabic or English.

Journeys follow the student’s stage: first enquiry, enrollment, student life and alumni. If a message isn’t delivered or read, the journey can fall back to SMS or email.

And people stay in the loop. Your team decides who gets a check-in. Your advisors pick up the conversation when a student needs more than an automated reply.

5 things to do before the semester starts

  1. List every message a new student gets in their first 30 days. Note the channel, the sender and the ask.
  2. Add an opt-in to registration. One plain line about what you’ll send on WhatsApp.
  3. Move time-sensitive asks to WhatsApp. Fees, documents, timetables and housing. Keep email for formal records.
  4. Name the human. Decide who answers replies, and how fast. Then tell students.
  5. Pick two numbers to watch. Reply rate and task completion. Not messages sent.

Questions universities ask

Is WhatsApp acceptable for official university communication?

It can be. Use Meta’s official business platform, get students’ opt-in and follow your institution’s data policy. Keep email for documents that need a formal record.

Will students find university messages intrusive?

Relevance decides that. A personal, timely message from their own university reads as help. A weekly broadcast reads as noise. Let students choose topics and opt out easily.

Should universities stop using email?

No. Use email for records and long information. Use WhatsApp for the moments that need a reply or an action.

The shorter version

  • Students in the Gulf are online most of the day, and WhatsApp is where they talk.
  • Messages work when they’re personal, timely and from a sender students trust.
  • Mass nudges with no follow-up were tested on more than 800,000 students. They didn’t move enrollment.
  • What works: a channel students open, one clear ask and a person behind it.
