Responsive email design has been growing steadily in popularity. Some brands turn to responsive design techniques to create better experiences for their subscribers, and in many cases, increase their click and engagement rates.
The foundation of responsive email design is built upon CSS3 media queries, which can be confusing and complicated to learn. And like everything else in email, they don’t work quite the same way in our inboxes as they do on the websites we view in browsers.
This is a how-to guide for responsive email design. See what is possible with responsive email design, how to implement media queries in your design, and support for responsive emails in various mobile email applications.
Mailpile is a modern, fast web-mail client with user-friendly encryption and privacy features. 100% Free and Open Source software. It’s free-as-in-freedom personal e-mail searching and indexing tool, largely inspired by Google’s popular proprietary-but-gratis e-mail service. It wants to eventually become a fast and flexible back-end for awesome personal mail clients, including webmail.
Mailpile is still experimental and isn’t actually very useful yet. It’ll tell you that you have mail matching a given search and let you sort it, browse threads and read messages… but the user interface and message composing/sending functionality is still very immature. If you just want a useful tool and aren’t interested in hacking on the code, you should probably check back later for updates.

Raindrop is an exploration in messaging innovation being led by the team responsible for Thunderbird, to explore new ways to use Open Web technologies to create useful, compelling messaging experiences.
A central principle behind Raindrop is that messaging should be personal — they want Raindrop to be people-centric both in how they process messages, and in how they can help give people control over their personal data and experiences.
When a friend’s link from YouTube or flickr arrives, your messaging client should be able to show the video or photos near or as part of the message, rather than rudely kicking you over to a separate browser tab.
Notifications from computers and mailing lists should be organized for you, not clutter your Inbox or require tedious manual filter setup. It should be easy to smoothly integrate new web services into your conversation viewer entirely using open web technologies.
