    RPost
    RMail is great for sending emails with information that is sensitive but that the recipient is not going to put a lot of work into retrieving. I do psychological evaluations for criminal courts and I use it to send reports to courts and attorneys. I need to use something compatible with HIPAA privacy rules, which courts and attorneys are typically not as concerned about. If they had to use a password or go to an outside web address to retrieve the email, they wouldn't do it. It's also common for an attorney to say they didn't get an email, but I always know if they did or not, and I have clear documentation of it, which is important in legal cases.

    Zimbra is great for an email system for a medium or large organization with appropriate IT staffing. The system is easy to use for end-users, and has a fantastic web interface. Unfortunately, it is overly complex, when considering staffing requirements and price, when compared with Office 365 or Google Apps for smaller organizations. For other education customers, it is hard to compete with Microsoft and Google providing their services for "Free" now though

    Pros
    RPost
    • Read receipts tell you the time a message was actually opened
    • The electronic signature feature is nice, and usually not included with these types of services
    • Many times, a recipient doesn't need a password to open their email. RMail leverages TLS technology in most cases
    • Recipients do have the option of creating an account, but generally they don't need to
    • Outlook integration is very easy to set up
    • Gmail integration within Chrome is pretty amazing

    Cons
    RPost
    • Program plug-in crashes on occasion.
    • Issues can arise if your computer's clock is not synced to RMail's time servers.
    • Setup was initially tedious (but has gotten much better since 2019).

    • Zimbra's mobile application leaves much to be desired; it is its weakest point.
    • This forces the use of third-party applications on smartphones, which only offer a more or less complete integration with the ActiveSync protocol.
    • Zimbra allows for an on-premise scenario, which is not for everyone, especially considering that the trend nowadays is to outsource email; in any case, it also offers this alternative.
    • The cost of Zimbra as a SaaS solution comes too close to that of more widely adopted competing options.
    • Zimbra lacks a robust integrated chat system, which its competitors offer.
    • It lacks AI integration.

    I don't think RPost has any competition, at least none that I can use. I think that once registered email becomes widely accepted (someday soon?), it will be indispensable for anyone in business, and RPost is the leading vendor (maybe the only vendor).

    Usability
    RPost
    It is as simple as downloading a plug-in or installing a chrome extension, then you click a button to use it. The interface is straightforward.

    The web usability of the solution is adequate, with all functions integrated into a single interface. However, it is important to note that in the desktop environment, it lacks its own application and relies on ActiveSync synchronization with reference solutions like Outlook or Thunderbird. Some features, such as the briefcase, will be excluded. The same happens on smartphones.It is also common for competing solutions to include integrated chat or video call tools, which Zimbra lacks. These shortcomings are among the most frequently requested by users.

    Support is easy to access via email or phone. They also reach out to you periodically with new features, but they aren't intrusive about it. I usually appreciate it when I get an email from RMail, which is not very often.

    Overall, we were satisfied with the implementation. We perhaps should have spent more time consulting with Zimbra or others regarding best practices but as we got to know the system better we were able to make changes relatively easily after the fact.

    RMail is really useful when wanting to send important encrypted information, and have control of what happens on the other end. It also comes with a complete set of features that help in any other way you can imagine. I've been through other products, and nothing compares to it.

    Zimbra is a significantly cheaper option than one of the Microsoft solutions, such as Exchange. It is able to run in a free environment, as it is in the case of Linux. It offers the advantages of a powerful mail manager, such as indexed searches and the integration of contacts and notes, all in one platform. It is constantly updated and the operation of its connection in mobile equipment is remarkable and very efficient. Additionally, it is able to easily integrate with Outlook solutions with its connector, which brings all the benefits of Zimbra to the user under the interface known as "mail manager." So far, I have been using Zimbra for several years and I have not missed my previous work platforms.

    Return on Investment
    RPost
    • There's not much ROI, because we don't get it much cheaper than the list price.
    • However, being able to offer this service strengthens our service offerings.

    • Zimbra is a cheaper email service than other similar platforms and in my point of view offers better features, that's why the company migrated services to this platform several years ago and without a doubt, it has been the best investment.
    • Zimbra has a more user-friendly interface for employees, this has improved response times to external customers of the company.
    • The implementation of Zimbra in the company motivated the IT engineering department to make improvements in open source to adapt it to the needs of the company.
