Where the 98% WhatsApp open rate figure actually comes from
It comes from a vendor's own marketing material, not from an independent study. The figure traces back to MessengerPeople (now Sinch Engage), a company that sells WhatsApp broadcasting tools — a business with an obvious incentive to make the channel look unbeatable.
No published sample size, no methodology, no date range. Just a number that got quoted, then requoted, until it became "common knowledge" across marketing blogs, agency decks and — yes — plenty of chatbot vendor sites too. Searchlab's WhatsApp Business Statistics 2026 documents this exact sourcing problem and lands on a more defensible range for real-world use: 60-80%.
That's still a strong number. It's also nowhere near 98%, and it moves a lot depending on who you're messaging and how you built the list.
Why this matters for an Australian admissions team
If your marketing team is reporting a 98% WhatsApp open rate against a 25% email open rate to justify budget, the comparison isn't just optimistic — it's comparing two different events. One of the two numbers is being measured honestly; the other one usually isn't. TEQSA-registered providers running enquiry-to-enrolment pipelines through UAC, VTAC or QTAC application windows need numbers that hold up when a marketing spend review asks where they came from — the same discipline covered in our guide to digital marketing for higher education.
What Skolbot actually measures across partner-school WhatsApp campaigns
Real read rates depend entirely on list quality, and the range is wide enough that quoting a single figure is misleading on its own. Across Skolbot's WhatsApp deployments for school admissions campaigns, three list types produce three very different outcomes.
| List type | Measured read rate | What drives the difference |
|---|---|---|
| Well-managed, tightly segmented opt-in list | 90-94% | Recent consent, relevant content, small enough to personalise |
| Average opt-in broadcast list | ~68% | Mixed recency and relevance, larger send volume |
| Broad, poorly segmented mass send | ~38% | Stale contacts, generic content, no segmentation |
(Source: internal Skolbot benchmark — content/zpd-bank.json#whatsapp-read-rate-vs-email-open-rate)
The ~68% figure for an average opt-in list is consistent with the broader averages platforms like Braze report across their own customer base, which is a useful sanity check — it means Skolbot's numbers aren't an outlier produced by a small or unusual sample.
None of these three numbers is 98%. All three are still well above what most schools see from email, which is the actual point worth making — WhatsApp doesn't need an inflated headline figure to be the stronger channel.
Why a WhatsApp read receipt and an email open aren't the same event
A WhatsApp read receipt — the blue double tick — fires when the recipient's device actively displays the message. Meta's own developer documentation on the messages status webhook confirms the "read" status is tied to the message being shown on screen, with the recipient's read receipts setting turned on.
An email "open" is a different mechanism entirely. It usually fires when a tracking pixel — a tiny, invisible image embedded in the email — loads from a server. That happens when a person opens the email and views images. It also happens automatically, whether or not a human ever looks at the message.
Why Apple Mail Privacy Protection breaks the comparison further
Since 2021, Apple Mail Privacy Protection pre-loads every tracking pixel for opted-in Apple Mail users, on Apple's own servers, before the recipient ever opens the message. The email registers as "opened" regardless of whether the recipient reads it, deletes it unread, or never looks at their inbox that day.
A 2024 Validity study measured the gap this creates: reported open rates were inflated by 18 to 32 percentage points above verified engagement for senders with Apple-Mail-heavy subscriber lists (Validity, Case Closed: The Mystery of Declining Email Open Rates). A school reporting a 45% email open rate may be looking at genuine engagement in the high teens once Apple's auto-preloading is accounted for.
Rule: never present "WhatsApp 98% vs email 25%" as the same metric. One number describes a message displayed on a recipient's screen. The other number, for a meaningful share of any Australian contact list, describes a background request an operating system made on the recipient's behalf without them touching their phone. They are not measuring the same behaviour, and stacking them in the same chart misrepresents both channels.
Three metrics worth tracking instead of a headline open rate
None of these require new tooling — most schools already have the data sitting in their WhatsApp Business platform and CRM, just not surfaced this way.
Read rate segmented by list quality
Report read rate against the specific list segment it came from, not as a single blended figure. A campaign sent to a tightly segmented, recently opted-in group of applicants will always outperform a broad re-engagement send to contacts who enquired eight months ago — reporting them together hides which list-building work is actually paying off.
Response rate
Read rate tells you a message was seen. Response rate tells you it prompted action, which is the number that actually correlates with enrolment-pipeline movement. On an opt-in WhatsApp list, expect an average response rate of 22-28% — track this per campaign and per segment, the same way you'd segment read rate.
Cost per qualified conversation, in AUD
Not cost per prospect, and not cost per "open." Cost per qualified conversation — a two-way exchange where the prospect asks a real question about enrolment, program fit, or next steps — is the number that ties channel spend to something admissions staff can act on. If a WhatsApp campaign costs your school $1,200 AUD in platform and staff time and produces 80 qualified conversations, that's $15 AUD per qualified conversation — a figure you can compare directly against your cost per qualified conversation on email or phone outreach, something an open rate never lets you do. This is the same metric discipline behind our guide to student acquisition ROI.
What this means for consent and messaging in Australia
WhatsApp Business messaging to Australian prospects sits alongside existing rules, not outside them. The Spam Act 2003, enforced by ACMA, requires consent before sending commercial electronic messages, and the Privacy Act 1988 and the Australian Privacy Principles govern how personal data collected through those conversations is stored and used. None of this changes the measurement problem above — it's a separate compliance layer schools should already have covered for email and SMS, and WhatsApp sits under the same expectations.
For the broader case on why WhatsApp outperforms phone outreach for international applicants specifically, see International Student Recruitment: Why WhatsApp Beats the Call — a genuinely different question from what to measure once the channel is running, but one that shapes which list segment your read-rate numbers will come from.
FAQ
Is the 98% WhatsApp open rate figure completely made up?
Not fabricated, but unverifiable. It traces to marketing material from MessengerPeople (now Sinch Engage), a vendor selling WhatsApp tools, with no published sample or methodology behind it. Independent analysis puts real-world WhatsApp engagement at 60-80% in typical use, and Skolbot's own measured data shows a range from 38% to 94% depending entirely on list quality.
Why does my email platform report a higher open rate than what people actually see?
Apple Mail Privacy Protection auto-loads the tracking pixel that email platforms use to register an "open," for every opted-in Apple Mail user, whether or not the person reads the message. A 2024 Validity study measured this inflating reported open rates by 18-32 percentage points above verified engagement on Apple-Mail-heavy lists.
What should a school report to its board instead of open rate?
Read rate segmented by list quality, response rate, and cost per qualified conversation in AUD. These three numbers show whether messaging spend is producing conversations that move applicants toward enrolment, which an open rate — WhatsApp's or email's — doesn't tell you on its own.
Does a lower WhatsApp read rate on a broad list mean the channel doesn't work?
No — it means the list wasn't segmented well, not that WhatsApp underperforms. The gap between a 94% read rate on a tightly segmented opt-in list and a 38% read rate on a broad mass send is a list-quality problem, and it's the same pattern any channel shows when messages go to people with weak or stale consent.
Does TEQSA or ACMA regulate WhatsApp messaging specifically?
Not as a named channel. WhatsApp Business messaging to Australian prospects falls under the Spam Act 2003 (enforced by ACMA) for consent to commercial electronic messages, and the Privacy Act 1988 and Australian Privacy Principles for how personal data from those conversations is handled — the same general obligations that already apply to email and SMS outreach.
