Top 10 Webmail Clients in 2024

Despite the rapid technological advancements of recent years, one thing remains clear: email is here to stay. Amidst the proliferation of new communication channels and the disruption of the AI revolution, email continues to stand tall as the backbone of professional communication.

With the rise of remote work and the need for seamless email management across multiple devices, choosing the right email client becomes paramount. That’s why webmail clients are so attractive: they make sending and receiving emails through remote and local mail servers easier than ever. And they provide this convenience through IMAP, SMTP, and POP3 protocols. 

Amidst the myriad of options available, for this article, we’ve chosen to spotlight PHP and AJAX-based webmail clients. While email client giants like Microsoft Outlook, Gmail, and Apple Mail dominate the market, delving into the unique features and functionalities of these alternative webmail clients will provide insights into tailored email experiences that can cater to your unique user needs and preferences.

Key takeaways

  • The difference between a webmail client and an email client lies primarily in how they are accessed and where emails are stored. Webmail clients are accessed via web browsers and store emails remotely on servers, while email clients are standalone applications that store emails locally on the user’s device.
  • PHP and AJAX-based webmail clients provide unique advantages, especially when integrated with hosting platforms like Plesk.
  • The top 10 webmail clients for 2024 options range from enterprise-focused solutions like Horde to lightweight clients like RoundCube and AtMail.

Below, we’ll explore the ten most popular PHP and AJAX webmail clients available. They look and seem like any other computer application when you use them daily, and work as well too. While open-source coding allows you to tailor some of them to suit your requirements, that’s not the case with all of them. That’s why it’s crucial to check their licenses in full and find out what’s allowed.

Email clients, such as Microsoft Outlook or Apple Mail, are standalone applications installed on devices that retrieve emails from remote servers and store them locally. On the other hand, webmail clients are accessed through web browsers and store emails on remote servers, offering accessibility from any internet-enabled device. While email clients provide offline access and advanced features, webmail clients offer convenience and accessibility from anywhere with an internet connection. By understanding the differences and use cases of each, individuals and businesses can choose the communication tool that best aligns with their needs and preferences.
