The real WhatsApp open rate, measured instead of quoted

A read receipt only arrives if the recipient has them switched on. Turn them off and you read the message while the sender never sees a blue tick.

This measurement included people who replied without ever producing a read receipt. They certainly read the message, and they are not in the 85.9 percent.

That makes the error one-sided. The real number is higher than what you measure, never lower. You know which way you are wrong, which is exactly what you want to know about a figure.

The pattern that stands out is not in the average but in the order. Practically everyone sees the first message. On the second, third and fourth the percentage visibly drops.

That says less about WhatsApp than about what you send. A message that follows something the reader just asked about gets read. A reminder about something they have gone cold on stays unopened. Exactly like a conversation.

Even at the bottom of that sequence it stays well above what email achieves. But anyone building a campaign on the assumption that every following message is read just as well is flattering themselves. Plan the follow-ups on relevance, not on a schedule.

This decay belongs to this kind of campaign. For a message someone is waiting for, an appointment confirmation or a reminder for something they booked themselves, relevance is at its highest the moment it arrives. We have not measured that at enough volume to put a percentage next to it, so that figure is not here. It goes in as soon as it exists.

Email measures opens with an invisible image. If the image loads, it counts as opened.

Since Mail Privacy Protection, Apple loads that image in the background the moment the message arrives, whether or not anyone looks at it. Corporate servers that scan incoming post do the same. At the same time plenty of people block images, and then a message that genuinely was read is never counted.

So email counts what nobody read and misses what people did read, and nobody can say which effect dominates. That is a different kind of unreliability than a floor. The honest comparison is not 98 against 20. It is a number whose direction of error you know against a number whose direction you do not.

Nobody can measure 98 percent, including us, and that is the point. A read receipt is the only unit of measurement there is, and it is missing for everyone who has them switched off.

Chatarmin, a German company selling WhatsApp marketing software, writes it down themselves: roughly 98 percent real, roughly 80 percent measurable, because privacy settings hold back the blue tick. In their own study of more than thirty e-commerce brands, each with over a hundred thousand WhatsApp conversations a year, broadcasts land between 60 and 80 percent and flows between 70 and 90 percent, counted over delivered messages.

Our 85.9 percent sits at the top of that range. The 98 percent is not a measurement but an estimate of what would happen if everyone had read receipts switched on. Anyone presenting it as a measurement leaves that sentence out.

Four things, and publish them together.

Every campaign we build writes the status of every message: sent, delivered, read, with the timestamp.

It sits in the client dashboard, per message, with the underlying rows next to it. Not because it looks good, but because a number you cannot look up is not a number.
