Responsive Emails are so hard to make…

Breakpoints in Email

Truth! Even emails that are not responsive are hard to code and display intact in all email clients, many of which have various peculiarities (yea, looking at you Outlook). This is also one of the reasons other email builders are so limited, more design freedom can cause the email to 'break' in some clients.

With RED all that is in the past. Powered by an innovative email code generator and built upon a solid foundation, emails are displayed consistently across all (major) email clients. On top of that, RED offers design options and layout tools unique to any email editor, allowing for a rich email experience on large screens and mobile devices alike. Now, that's a powerful app indeed!

*Foundation inspired by ink, an excellent project done by the talented people at Zurb.

Grid Based Design

Email design is all about deeply nested tables, but RED shields you from that complexity. With rows and easy control over the number of columns, it feels like designing for the modern web. Indeed, the columns can stack too!

Focus on the message and support it with a fitting layout and meaningful design. Send drafts or tests directly through RED. Get input, prototype content, test links or simply see what the email looks like on different devices and email apps.

Mailchimp, Constant Contact and (some of)
the other EMSPs are really great but…

Their email builders are based upon a rigid template structure, limiting design freedom. Also, custom breakpoints and style changes for mobile are not offered. On the other hand, their infrastructure for email sending, delivery and analytics rock!

RED was created to be complementary and offer email design freedom through progressive enhancement. The amicable export code RED generously offers is already making friends. Direct integrations are in the works too!

Yes, RED does send emails...intended for content approval, and link or email client testing. For sending, RED can be connected to a personal or business email account such as Gmail, or an SMTP server.

Email is…

The original social media


With just about everyone having an email address, including built-in features for personal and group conversation, it is the largest social platform. The nifty forward button makes both personal and group sharing a cinch.

Controllable and very lucrative


It's easier to reach an audience using email than with the current social media services.

Patient yet actionable


Emails wait for the receiver. It's personal, not invasive, yet hard to ignore. It sits comfortably in the inbox until the intended reader takes action and reads or (re)moves the message.

The most popular mobile activity


Mobile opens have grown over 180% over the 3 years. About 65% of email opens happen on the mobile device first. Most people read email on the phone or tablet immediately when they wake up.
