This report describes the results of a survey of 917 organizations of all sizes to determine the email systems they are using, the versions deployed, migration plans, and the cost of the software. Responding organizations account for 10.6 million employees, or roughly 2% of the workforce in developed industrialized economies.

The results provide hard evidence for a variety of important decisions, such as:

  • Product development plans
  • Market size projections
  • Migration plans between software versions

Selected, Illustrative Findings

Exchange:

  • Exchange has about 65% market share across all organizations.
  • It has a 75% penetration in health care businesses with more than 5,000 employees.
  • Exchange does very well in telecommunications industries with at least 1,000 employees, where it has a 90% penetration.
  • Almost all organizations with up to 49 employees are on Exchange 2007. More than 40% of Exchange seats in organizations with over 10,000 employees are on Exchange 2003. About 5% of Exchange-using organizations with up to 500 employees are on Exchange 2003. Exchange 5.5 has almost disappeared.

Notes/Domino:

  • Notes/Domino has about 10% market share across all organizations. It is at its strongest in manufacturing and financial industries, with more than 55% market share in manufacturing industries with at least 5,000 employees. Among health care industries with at least 2,500 employees, it has a roughly 25% market share.
  • Some 55% of Notes/Domino seats in organizations with fewer than 100 employees are on version 7. Fewer than 5% of Notes/Domino seats in organizations with at least 1,000 employees are on version 5.

POP/IMAP, GroupWise:

  • Internal and hosted POP/IMAP solutions are used in about 15% of organizations of all sizes. POP/IMAP products are more popular in education and technical consulting than in other industries.
  • Some 5% of large organizations use a POP/IMAP-based email system.
  • Novell GroupWise has a negligible overall market share. However, GroupWise has its niches, notably organizations in the financial services and government sectors with 100 to 999 employees. In those sectors, it has a 10% and 15% market share, respectively.
  • The survey does not support the contention that small and medium-size organizations are migrating from on-premises software to hosted services (which would usually be classified as POP/IMAP solutions).

    While the report looks interesting, I have to think your sample is not random enough or significant based on the fact that you obviously did not target or receive many Domino respondants. The latest IDC numbers show Exchange at (and I’m going off of memory here, so I might be off by a point or 2) about 48% market share, and Domino at about 43%. The remaining scraps were held by POP/IMAP, GroupWise, Oracle, and others. It certainly isn’t anywhere near the 65% and the 10% you cite. 65% is almost feasible, but 10% for Domino? Once you had that, you must have realized your information was skewed and statistically insignificant.

    Mike,

    Thanks for the feedback. This study was over 917 organizations, with a total of 10.5 million employees. This is roughly 2% of the workforce in developed economies. We believe it is by far the largest survey to determine market shares. Also, as far as I can see, IDC’s figures are not based on a survey, but on information provided by vendors. Vendor information is unreliable. Our survey is not perfect, but I do believe it’s statistically significant. I believe the market share picture it presents is an accurate one.

    BTW, to help us interpret your comment, please can you let us know what you do, who you work for, and the nature of your relationship with Lotus? Maybe you could post here, or drop me an email directly--david.ferris@ferris.com.

    Thanks again

    David,

    Per your request, my background in this market is this:

    I work for Orange Business Services, which was formerly Equant. We are part of the France Telecom group. It is my job to sell consulting and managed services around all things collaboration and mobility. My territory is the US & Canada, and our focus is on the enterprise; we cannot focus or scale for the SMB market. We sell to both Microsoft and IBM shops. My team has expertise in both technology sets. We manage 10s of thousands of seats of both products. We have done consulting engagements migrating shops from one to the other.

    Orange is a Gold partner with Microsoft and a Premier Partner with IBM. As for me, I used to be an independent Domino admin, so my heart has always been there. I won’t hide that, and quick Google of me would bring that to light. However, I’ve been in this role at Orange for over 4 years, and I have sold engagements to Microsoft and IBM shops. We man a booth at shows for both vendors. We are truly as agnostic as it comes when it comes to the collaboration market.

    The numbers I mention in the previous post are based on several years of meeting with customers. I can assure you that Domino has a much larger market share in the enterprise than 10%. 10% is akin to the share that GroupWise, Oracle, or POP/IMAP has, and we all know that is not the case.

  4. 4 David Ferris

    Mike,

    Many thanks for the input.

    Your intuitions are sound. In the enterprise, Notes/Domino has a much higher penetration than 10%. To find out what its penetration is in that sector, can I tempt you to purchase the report? (hopeful look on face).

    BTW, Oracle Collaboration Suite has almost no penetration in organizations of any size. Unless we included Oracle itself, none of the 900+ respondents use it.

  5. 5 Brad Cooper

    Thank you, David, for this report on email client market share. Did your study include non-profit organizations or just for-profit’s? My hunch tells me that the Notes penetration for large non-profits is also higher than 10% (i used to work for one that had Notes), but would be curious to know if you can slice the data this way?

    Best regards,
    Brad

    David,

    Do you have anything to add to the discussion with Ed Brill regarding the accuracy of your research?

    Gary

  7. 7 dferris

    Gary--No, I don’t plan to respond to Ed’s objections. I don’t think they are valid. The survey is an accurate reflection of market shares, and the industry trend.

  8. 8 dferris

    Brad--sorry about tardy reply to your inquiry. The report is not focussed on for-profit. There are many not-for-profits involved--the public sector is a large proportion of most developed economies. If you mean charities, there are probably some charities among the respondents, but not a lot--I guess maybe five to 10 in all
