    Don't you hate downloading .docx and .xlxs files just to see what's inside? With CrossBox, you can preview any document, spreadsheet, presentation, image, audio, or even video directly from your inbox.

  • Multi-Account

    If you have more than one email address, you can sign in to multiple accounts at once. That way, you can switch between accounts without signing out and back in again.

  • Size Matters

    How many times you wanted to send an email with a couple of attachments only to find out that you can't — the email size limit is being forced on you — typically 25MB or less! With CrossBox, you can send huge files to any email address, without the need for anyone involved to use a third party sharing app.

  • Send Later

    You've just finished writing an email. But it's late. You wouldn't want to disturb anybody in the middle of the night! With CrossBox, it's easy to schedule a timed email delivery. Just choose — for example, Monday at 8:30 am. When your contact gets to the office, they'll see your email first.

  • Email Snoozing

    Emails are piling up, but you don't want to deal with them right now? With CrossBox, you can snooze any conversation. Just choose time  — for example, tomorrow — and it will remain out of your sight until then. Focus on what matters, and experience a more productive inbox.

  • Security and Access Recovery

    With built-in Two Factor Authentication (2FA) support, CrossBox helps you add an additional layer of security to your email address. On the other hand, several recovery options are available for those that lose access to the email account.

    Are you tired of replying to the same question over and over again? Canned Responses help you quickly send predetermined responses to common questions you get in your email every day. Free your time and reply within seconds instead of minutes.

  • Get more done with multitasking

    Multitask like a pro with the ability to minimize your windows and quickly switch between different activities in real-time. You can perform multiple tasks simultaneously, like being in a conference call and replying to an email at the same time.

    40+ productivity and collaboration features

White-label
Android & iOS Apps

Use the CrossBox Online Apps Builder to download your own, white-labeled smartphone and tablet CrossBox Apps. Publish them to Google Play and App Store and provide your customers with easier access even when on the go.

Cluster

Are you a Web Host, Email Service Provider, or ISP? CrossBox Cluster lets you provide a superb communication experience to all your users across any number of servers. It can plug and play into your existing infrastructure without requiring a single change in your current server setup.

Cluster Mail

Many servers mean a lot of confusion and many IMAP, POP3, and SMTP hostnames. With CrossBox Cluster, you can have a single, easy to remember hostname for all your customers — for example, mail.my-company.com.

Cluster Webmail

What do you like more: each server with its own Webmail URL or a single Webmail URL for all your servers? Everyone told us it's the latter, so we made it possible.

Scale Indefinitely

With CrossBox Cluster, you can both add and remove servers seamlessly within the admin area. The changes you make automatically propagate to your central IMAP/SMTP/POP3 hostname and Webmail URL.

Mix Different Servers

A cluster can contain any number or combination of Standalone, DirectAdmin, cPanel or Plesk servers — allowing you to unify communication experience for all your customers, across different server types and configurations.

Empower Your Brand With White-label

Match the UI with your own brand by giving CrossBox a custom name, logo, and color scheme. Apart from the branded web version, fully white-labeled Android & iOS Apps will distinguish your brand even further!

Make It Your Own

Use The Infrastructure You Already Have

CrossBox features a drop-in integration with the industries' most popular control panels. Alternatively, install the standalone version — prepackaged and preconfigured with everything you need to be up and running in no time.

Standalone cPanel DirectAdmin Plesk

Unlimited Domains & Users per Server

No need to reach for your wallet each time you create a new email address. With CrossBox, you can host unlimited domains and accounts with a single server license — the price stays fixed.
