GrokWhere the 98% WhatsApp open rate figure actually comes from
It comes from a vendor's own marketing material, not from an independent study. The number traces back to MessengerPeople, a WhatsApp tooling vendor now folded into Sinch Engage — a company that sells WhatsApp messaging infrastructure and has an obvious commercial interest in WhatsApp looking unbeatable next to email.
No published sample size. No methodology. No date range. Searchlab's WhatsApp Business Statistics 2026 documents exactly this problem: the 98% figure gets repeated across hundreds of marketing blogs and sales decks, each one citing the last, with nobody able to point to the underlying dataset. Searchlab's own review of real-world usage lands on a 60-80% range — still strong, but nowhere near 98%, and with an actual source attached.
This is a circular citation problem, not a lie any single source is telling. Marketing content about WhatsApp cites other marketing content about WhatsApp, and the industry that sells the channel ends up being the only source measuring it. That's worth flagging plainly before a school builds a channel-mix decision on top of it.
Even our own pillar guide on digital marketing for higher education and our companion article on international student recruitment and WhatsApp reference the widely cited figure — the second one via ICEF Monitor, a respected EdTech publication, not a WhatsApp vendor. That's worth sitting with for a moment.
Even a credible EdTech source repeats the unsourced number
The 98% figure isn't confined to low-grade vendor blogs — it has made its way into respected industry publications too, which is exactly why it's so hard to unlearn. ICEF Monitor's analysis of WhatsApp in the student journey cites "open rates as high as 98%" while making a genuinely useful case for WhatsApp in international recruitment.
ICEF Monitor isn't the problem here, and this isn't a case for distrusting the publication. It's evidence that the figure has become background knowledge across the sector — repeated by serious analysts, not just vendors chasing a sale — which is precisely what makes it worth checking rather than quoting.
A number that's survived this many retellings, with this little scrutiny of its source, is exactly the kind of number a school should verify before putting it in a board deck or a channel-mix business case.
Why WhatsApp read receipts and email opens aren't the same measurement
They aren't comparable because they measure two structurally different events. A WhatsApp read receipt — the blue double tick — fires when the message is actually displayed on the recipient's screen. Meta's own developer documentation on the messages status webhook confirms this: the "read" status only fires on genuine on-screen display, an active exposure signal tied to a real human looking at a real phone.
An email "open," by contrast, usually fires when a tracking pixel — a tiny invisible image embedded in the email — loads on the recipient's device. That's a proxy for opening, not proof of it, and the proxy has been broken since 2021.
Apple Mail Privacy Protection (MPP) automatically pre-loads every tracking pixel for every opted-in Apple Mail user, whether or not the recipient ever looks at the email. Validity's study, "Case Closed: The Mystery of Declining Email Open Rates," found reported open rates inflated by 18-32 percentage points above verified engagement for senders whose lists lean heavily toward Apple Mail — which describes most UK student and parent audiences, given how dominant iPhone and Apple Mail are among that age group.
Put the two side by side and the comparison collapses on inspection: a WhatsApp read receipt says "this person's eyes were on the message," while an inflated email open rate can say nothing more than "Apple's servers fetched an image automatically." Treating them as the same metric — "WhatsApp: 98%, email: 25%" — invites a school to make a channel decision on numbers that were never measuring the same thing.
What Skolbot's own data shows about WhatsApp read rates
The direct answer: read rates vary enormously by list quality, and a single blended average hides that variation completely. Across 40 WhatsApp campaigns run for partner schools with prospects and parents in 2025-2026, Skolbot's data separates cleanly into three tiers.
| List type | Measured read rate | What drives the difference |
|---|---|---|
| Well-managed, tightly segmented opt-in list | 90-94% | Recent opt-in, relevant content, small enough to stay warm |
| Average opt-in broadcast list, less finely segmented | ~68% | Mixed recency, broader targeting, some cold contacts |
| Broad, poorly segmented mass send | ~38% | Large list, stale opt-ins, generic content |
The 68% figure for average broadcast lists sits close to what platforms like Braze report across their own customer bases, which is a useful cross-check — it means Skolbot's numbers aren't an outlier, they line up with independent third-party data at the "average" end of the range.
None of these three numbers is 98%, including the best-case tier. A well-run, freshly opted-in list of engaged candidates still tops out around 90-94% — genuinely strong, comfortably ahead of email, but a real measured ceiling rather than a marketing rounding-up to "basically everyone."
Response rate matters as much as read rate, and it's a smaller number by design — being read isn't the same as prompting a reply. On an opt-in list, Skolbot measures an average response rate of 22-28%: roughly a quarter of prospects who read a message go on to reply or engage further, which is the number that actually predicts whether a channel is producing conversations rather than just deliveries.
Response rate is also where an unstaffed inbox quietly caps its own upside — a candidate who replies at 11pm to a question about deadlines gets no answer until the next working day unless something is watching the channel. Our WhatsApp chatbot article on the Gen Z channel covers how automating that first reply keeps the response-rate number honest around the clock, rather than only during office hours.
Three metrics to track instead of a generic open rate
A single blended "open rate" tells a school almost nothing actionable — replace it with three numbers that map to decisions you can actually make.
Read rate segmented by list quality, not blended into one average
Report read rate by tier — tightly managed opt-in, average broadcast, mass send — rather than as one number for the whole list. A blended 60% average could mean a healthy, well-segmented list, or it could mean a strong core group buried inside a much larger, poorly targeted send. The segmented view tells a marketing team where to invest in list hygiene and where the number is already close to the ceiling.
Response rate, not just read confirmation
Track how many recipients actually reply or take the next step, not just how many saw the message. A message can be technically "read" and still land completely inert if it doesn't prompt a candidate to ask a question, book a call, or move to the next stage. Skolbot's 22-28% response-rate benchmark on opt-in lists is a far more honest predictor of pipeline than any read percentage on its own.
Cost per qualified conversation, not cost per lead or cost per open
Tie spend to conversations with a real admissions officer, not to a message that reached a screen. Cost per open rewards volume; cost per qualified conversation rewards relevance, because it only counts contacts that turned into something an admissions team can actually work. A channel that reads at 94% but converts almost nobody into a real exchange is not outperforming a channel that reads at 68% and reliably produces conversations — the read rate alone can't tell you which is which.
FAQ
Is the WhatsApp 98% open rate figure real?
No independent, published study supports it. The number traces back to marketing material from MessengerPeople (now part of Sinch Engage), a WhatsApp tooling vendor, and has been repeated across the sector without anyone republishing a sample or methodology. Realistic figures, per Searchlab's 2026 review, sit in a 60-80% range depending on list quality.
Why do WhatsApp and email open rates get compared as if they're the same metric?
Because both get labelled "open rate" in dashboards, even though they measure different events. A WhatsApp read receipt fires only when a message is actually displayed on screen, per Meta's own webhook documentation. An email open usually fires when a tracking pixel loads, and Apple Mail Privacy Protection auto-loads that pixel for every opted-in Apple Mail user regardless of whether they read the email — Validity found this inflates reported opens by 18-32 percentage points above verified engagement.
What's a realistic WhatsApp read rate for a school's recruitment messages?
It depends heavily on list quality. Skolbot's own data across 40 school campaigns shows 90-94% for tightly segmented, well-managed opt-in lists, around 68% for an average broadcast list, and around 38% for a broad, poorly segmented mass send — three very different numbers a single blended average would hide.
Should a school stop citing the 98% figure entirely?
Yes, unless it can be attributed to a specific, methodologically transparent study, which so far doesn't exist. Even respected EdTech sources like ICEF Monitor have repeated the figure, which shows how deeply it's embedded — not that it's safe to reuse. Cite Skolbot's own segmented benchmarks or Searchlab's 60-80% range instead, and be explicit about which source you're using.
What should replace "open rate" as the headline WhatsApp metric in a marketing report?
Three numbers together: read rate segmented by list quality (not blended), response rate (did the message actually prompt an exchange), and cost per qualified conversation (spend tied to a real admissions conversation, not a message delivery). A single open-rate number, wherever it comes from, can't carry that much decision-making weight on its own.
