IBM Notes, popularly as Lotus Notes, has been a pioneer in the vertical of email clients since its introduction in the year 1989. Apart from the feature of emailing, Lotus Notes has an extensive range of other application as well. Most of the organizations do not configure Notes exclusively for the purpose of emailing, as the investment that is need to be done is very high. Thus, the organizations which plan to take advantage of the other applications as well, Lotus Notes has proved to be the first choice. Coming to the storage of Lotus Notes data, the entire data except contacts is stored in username.nsf file. The contacts are separately stored in names.nsf file. Since NSF is the proprietary database format of Lotus Notes, it is not supported in any other email client or application.

On the other side of the fence is Mozilla Thunderbird. Introduced in the year 2003, Thunderbird has been a popular email client owing to the various extensions and themes it offers. Thunderbird stores its emails in MBOX (Mailbox) files.
