Xuheki is a fast IMAP client which aims to become your preferred email client. It works in your browser and you can access it from anywhere to read your email. The interface is similar to a desktop-based email client and it’s completely “AJAX”—no page reloads.

It is designed with IMAP in mind. This has a downside—we don’t support POP3, nor other protocols, but the big advantage is that it makes use of certain IMAP features which allows it to be very efficient. It supports multiple folders; you can also create/remove folders from a convenient context menu. You can move messages to various folders using drag’n'drop.

The interface is designed to allow you to do multiple things at once. For example you are reading an email, then click “reply”. While you’re writing your reply, there’s an incoming mail. You can simply minimize the composer and to check the new message. You can compose multiple messages at once. The UI is driven by dialog boxes.

It has a basic address book and autocompletion of addresses in composer. Of course, it supports multiple users on the same installation. Xuheki is distributed under the terms of the GNU General Public License.

Requirements: Perl 5.8+, Apache 2, mod_perl 2, MySQL 5

Zenbe is started because they wanted the functionality and performance of a desktop application, and the simplicity and accessibility of webmail, at the same time, for all their email addresses. They wanted to access more features and services from the internet, without logging into a bunch of different websites everyday. They wanted better ways to share and work with friends, but they didn’t want to abandon email to use them.

Zenbe is free email that works with the email you already use. Zenbe offers many features, including email, online calendar, lists, mobile sync, file sharing, team collaboration. It even works with Facebook and Twitter. You can do them all without leaving your email.

With 4GB (and growing) of storage, you treat Zenbe like a computer you can access from anywhere. Sometimes, email just isn’t the best way to work together. With Zenpages, you can share files, email, events – anything you would share in an email – on a Zenpage.

If you like to stay organized with folders, you will love Zenbe’s email tags. Tags are like folders, but better. But with Zenbe’s excellent search, you don’t need to use tags to stay focused on what you care about. Zenbe is one of the best webmail experiences you can find.

The Email Standards Project is about working with email client developers and the design community to improve web standards support and accessibility in email. The project was formed out of frustration with the inconsistent rendering of HTML emails in major email clients.

Their mission is to drive the use and support of web standards in email, working with email client developers to ensure that emails render consistently. This is a community effort to improve the email experience for designers and readers, and they’d love your help.

They would like to help web designers understand why web standards matter for email, so that they are willing to get involved in making it happen. And also, they are providing as much assistance and feedback to the email client developers as they can. You can see the beginnings of this with their email acid test results.

Designing an HTML email that renders consistently across the major email clients can be very time consuming. Support for even simple CSS varies considerably between clients, and even different versions of the same client.

With 21 different sets of results, all the major email systems are covered, both desktop applications and webmail. It comes with the PDF and Excel version for download.

As web designers, we’ve grown pretty good at understanding how to create a modern, semantic, accessible website using XHTML and CSS. We understand what makes a good website, and how to make it happen.

When it comes time to design emails though, do all the same rules apply? Are there things we should be doing specifically for email that don’t make sense on a website? Campaign Monitor has published an article of 2008 Email Design Guidelines that shows us the technical, design and information elements that make up a successful HTML email.

• Don’t waste your readers’ time — An email inbox is a busy place, you won’t get much attention.
• Permission matters — Not only do you need to have permission to email people, but it helps to remind them of how they gave you permission, as specifically as you can.
• Relevance trumps permission — Just having permission is not enough, the content you are sending must also be relevant.
• Make unsubscribing easy — There’s no point emailing people who are not interested.
• Image blocking is common — You can’t rely on people actually seeing your images.
• Bring back tables — Structural tables are still often necessary for creating columns.
• Add inline styles — Gmail removes anything else.
• Don’t forget your plain text version — You can make blocks of text more readable.
• Meet your legal obligations — For example, CAN-SPAM for US senders.
• Test, test, test — It’s the only way to be confident about your design working.
