by Volker Weber

Email client usage worldwide, collected from 101 million email opens.

Very interesting indeed. This blend of all type of accesses tells a lot about the evolution of ways to consume E-Mail. Though maybe one cannot differenciate here different clients for the same user.

"Since determining the client in which an email is opened requires images to be displayed, the data for some email clients and mobile devices might be over- or under-represented due to automatic image blocking."

Or in other words: This dataset and the statistics they read from it are highly flawed.

I wonder how many emails had to be sent to get those 101 million email opens. Also wonder how many we're blogged by spam filters, and then of those that were opened how many used email clients that can block the loading of images and therefore not get registered.

Adam Brown, 2012-06-23 22:33

Hanno, I hear you. But do you have a better dataset? Or a better method?

Volker Weber, 2012-06-23 22:50

This survey rather elaborates on the security of a mail client and the spam filters in place. Most hits is most probably the least secure mail client.

It would be nice to also collect the X-Mailer header and later use to compare to those "open email" results. But all clients seems to include that header, so its not a 100% accurate science. In browsers, thats more easier.

I don't have a better dataset. A better method would be collecting mail headers at the SMTP servers of major providers.

This statistics page simply has the wrong headline. Call it "mail client distribution for users who open HTML newsletters" and there'd be no reason to complain about these results.

Hanno, Volker: Another method would be 'classic' Market Research: Draw a representative sample and ask people one way or the other.

Hubert Stettner, 2012-06-25 07:20

Hanno, indeed. It is very accurate for answering the question: which clients should you format your newsletters for?

Hubert, market research is blocked by Fritz!Box. :-)

It doesn't matter if some clients are over- or under-represented or missing at all. If we assume that the default client behavior for (not) opening the images didn't change (I've to admit I'm not a 100% sure of that) then the historical data for the listed clients is legit.

Which means the data shows a double in the usage of mobile clients (iOS, Android) while the usage of fully-fledged desktop clients (Outlook) was cut in half over the last year.

As there is no iOS or Android Mail Server, the mail boxes are probably still hosted where they used to be. It's just a rather dramatic change in how they are accessed. And as far as I remember Microsoft's revenue from Office was still solid, so all those users probably still have Outlook - they just don't use it that often anymore.

If you look at the mail integration in Connections 4, and listened to what the IBMers said at Lotusphere about the desire for mobile and simple interfaces, you know that they know.

What strikes me the most in all of these comments here is the underquestioning of IBM's consumer strategy and the over-representation of basic anti-Microsoft comments that reflect the past (that I've know as an ex IBMer) and current climate Inside IBM. Sad it is, it is sad. I'm a Microsoftee and I never see this behaviour Inside and outside Microsoft. Respect you competition. We deeply respect IBM as I do as a former IBMer.

Francois Cornely, 2012-06-25 21:47

Interesting concept, and wonder how much more they gather. Agree with some posts above that this should not be considered scientific research ;-)

Wouter Aukema, 2012-06-25 23:39

@Francois: Since when does IBM have a consumer strategy? If there is one IT company *not* playing in the consumer space it is IBM. I'm not saying they should or shouldn't. Just the don't.

Stephan H. Wissel, 2012-06-26 02:52

@Stephan : yes that's exactly the point. Some here try to explain the fact that Lotus Notes is not in this list... I think the reason is more simple... Consumerization makes it hard for IBM to compete on the client side of IT.
