SCOTTSDALE, Ariz. -- E-mail -- among the least glamorous of applications but arguably the most essential -- is a logical focus of developers showing productivity tools at the Demo 2003 technology conference here this week.

As the tech economy struggles to recover, Demo -- once a launching pad for bleeding-edge technologies -- is focusing more on the practical than the radical.And existing e-mail clients offer lots of opportunities for improvement.

"E-mail is the place where we're spending our business lives, and those products have to get a lot easier to use." said Chris Shipley, Demo executive producer, when introducing a session on e-mail. The event is produced by IDG Executive Forums, a sibling company of PC World.

E-Mail Overview

Afew of the mail-related products and services unveiled here include the following:

-- Bloomba: New e-mail clients don't come along every day, or even every year. But startup Stata Laboratories hopes to lure mail mavens to Bloomba. Although its streamlined interface looks much like Microsoft's Outlook Express, this POP3 client replaces folders with Google-like tools that dynamically organize your in-box according to search terms you specify. Bloomba also dispenses with a traditional address book in favor of an auto-fill feature that grabs names from your incoming messages. A free beta version is available for download.

-- Ella: Like Bloomba, Open Field Software's Ella aims to help tame overcrowded inboxes. But Ella is a plug-in for your existing e-mail client. You train it to sort incoming messages into folders organized by priority--for example, folders for business mail, personal messages, newsletters, and spam. A beta of a basic version of Ella for Outlook is due soon; the more powerful Ella Pro for Outlook and Lotus Notes is planned for later this year.

-- Oddpost: This strange name yields an interesting service. Oddpost is a new browser-based competitor to Hotmail and Yahoo Mail. It has a slick, speedy drag-and-drop interface that looks and performs more like a desktop app than a Web client. A $30 annual fee gets you 50MB of storage space, too.

-- KubiClient: Another new add-on for Outlook and Notes is Kubi Software's Kubi Client.
