Introduction

A lack of Standards

Digital communication has been experiencing constant transformation, with new technologies reshaping how we interact online. However, the technology underpinning email has been slow to adapt to modern web standards, often limited by outdated conventions and a lack of uniformity across platforms.

A lack of Email Standards

Historical context

The current situation

Email technology is based on a set of protocols such as the Simple Mail Transfer Protocol (SMTP) for sending messages, Post Office Protocol version 3 (POP3), and Internet Message Access Protocol (IMAP) for retrieving messages. The MIME (Multipurpose Internet Mail Extensions) standard was developed to allow emails to carry text in character sets other than ASCII, and to include attachments like images and documents.

The formatting of email content is primarily based on a subset of HTML and inline CSS, which is far behind the capabilities of modern web browsers. This is due to the need for compatibility across various email clients, some of which do not support the full range of HTML and CSS features. Email designers often have to resort to using tables for layout and inline styles for formatting, which is reminiscent of web design practices from the late 1990s and early 2000s. This has resulted in emails that are often static, unresponsive, and lack the interactive features that users have come to expect from websites and applications.

In the meantime, some modern email clients have started to support limited CSS3 and responsive design techniques, making emails more accessible on mobile devices. However, the vision of fully interactive and dynamic emails remains a work in progress.

Moving forward

The drive for Open Standards

Now, an initiative from Email 5 is taking on the challenge of creating Open Standards for email, aiming to infuse email communication with the rich capabilities of HTML5, CSS3, and JavaScript. Email 5's mission is to bring the email ecosystem up to speed with the rest of the web, allowing anyone to contribute to the development of email standards.

These standards would be developed and maintained by a consortium of industry leaders, including email client developers, marketers, and security experts, ensuring that they are universally accepted and implemented across different email clients and services. Standards bodies would need to address the aforementioned challenges, prioritizing security and user experience while ensuring that the benefits are clear and compelling.

The vision for future Open Standards for email communication is to bring the richness of web experiences into the inbox. By adopting HTML5, CSS3, and JavaScript, emails could transform into dynamic, interactive, and responsive messages.

  • HTML5: It offers a wide range of semantic elements and multimedia capabilities that could enhance the structure and content of emails. Video and audio content could be embedded directly within emails, forms could be used for quick surveys or feedback, and canvas elements could enable interactive graphics. This would not only improve the user experience but also open up new possibilities for creativity and engagement in email marketing.
  • CSS3: It brings advanced styling options and responsiveness to the table. With the introduction of CSS3 in emails, designers could utilize custom fonts, transitions, shadows, and animations to create visually appealing messages. Media queries would allow emails to adapt to different screen sizes and devices, ensuring that content is easily readable and accessible on mobile phones, tablets, and desktops alike.
  • JavaScript: Perhaps the most transformative aspect of future Open Standards would be the inclusion of JavaScript. Currently, for security reasons, JavaScript is not supported in email clients. However, with robust security measures in place, it could enable interactivity within emails that rivals that of web pages. Users could fill out forms, use dropdown menus, and even interact with small applications without ever leaving their inbox.

The future

The impact on email communication

Open standards are crucial for the evolution of email. They ensure compatibility across different platforms and clients, foster innovation, and maintain the internet's ethos of being open and accessible. The adoption of these Open Standards would have a profound impact on email communication:

  • Enhanced User Experience: Emails would become more user experience on par with modern web applications.
  • Improved Accessibility: With responsive design, emails would be more accessible on a variety of devices, ensuring that content is available to a wider audience.
  • Innovative Marketing: Marketers could craft rich, interactive campaigns that capture the attention of recipients and drive higher engagement rates.
  • Streamlined Workflows: Interactive forms and applications within emails could simplify processes such as appointment booking, feedback collection, and quick polls.

New challenges

Facing issues in creating Open Standards

The creation of Open Standards for email is not without its challenges, but the potential benefits are too significant to ignore. To address these capabilities, the Open Standards would need to include strict guidelines and sandboxing techniques to prevent malicious code execution. Email clients would implement security protocols to ensure that JavaScript runs in a controlled environment, minimizing the risk of vulnerabilities.

  • Email Client Diversity: There are numerous email clients, each with its own set of supported features. Creating a standard that works across all platforms (like Outlook, Gmail, Apple Mail, etc.) is a significant challenge. Client developers must be willing to adopt and implement these standards, which requires a concerted effort and a consensus that is difficult to achieve.
  • Backward Compatibility: New standards must maintain backward compatibility to ensure that no user is left behind. This complicates the introduction of new functions that may not be supported by older clients, and adding more complex features would exacerbate the problem.
  • Performance and Bandwidth: Introducing rich content and scripts could increase the size of email messages, leading to slower loading times and higher bandwidth usage. This could be a significant issue for users with limited data plans or those in regions with slower internet connections.
  • Lack of Incentive for Change: Many businesses and users are habituated to the current state of email and may not see the immediate benefit of overhauling the system. There is also the consideration of the cost and effort required to implement these changes, which may not be justified by the perceived benefits.
