Email Client Market Share Report
Sep 16 2008
Fingerprint just finished writing their first email client market share report. It’s the biggest study of email client usage ever conducted, using a sample of almost three million email recipients.
It’s exciting for them because it’s the first time they’ve released any of the data that’s been collected through Fingerprint. It shows the top 10 email clients in use for both consumer and business mailing lists.
I have been working on deploying it for our own newsletters (have you subscribed yet?), and will share OUR results soon.

It’s important to note, as you can see in the full study, that Hotmail is NOT actually more popular with business users than Outlook.
All versions of Outlook combined have a 36% share as opposed to Hotmail’s 33% share.
Perhaps it’s a slight distinction, but one worth noting.

Wow, I never realized so many people are so mislead.
The top several on each of these studies shows that the masses of people use a browser based or web mail. That tells me that they are new to using the internet and haven’t been shown a better way.
If you take the Web Based or browser based email out of the picture, then what would you have?
This is an interesting study…. Thank you for your efforts.

I’m not surprised.. most people don’t think of e-mail and the internet as different things. they go on the internet to check their e-mail… i.e. go to yahoo or hotmail and check their mail.
it’s simple, it’s worked for over a decade, makes sense.

Thanks for this.
With less than half of the business market and only a third of personal use, this confirms my thoughts that desktop based email clients are dead – and good riddance to them. It is frustrating, though, given this data that so many software companies are developing plugins and integration for outlook rather than web-based email clients.

@Idealpragmatist My company, Global Web Security Systems (gwebs) is now developing browser plugins for IE and Firefox that provide encryption for Hotmail, Yahoo and Gmail, and several more. Check it out: http://www.gwebs.com
