Features and specs

What each product offers, as listed by its team.

MailMoxie 5 features
CloudLinux 5 features
  • Technical Audits
    Automated checks for SPF, DKIM, DMARC, and BIMI.
  • Accessibility (WCAG)
    Audits for color contrast, screen readers, and semantics.
  • Blacklist Monitoring
    Real-time checks against 70+ global DNS blocklists.
  • Inbox Placement
    50+ spam trigger checks to ensure primary tab delivery.
  • Compliance
    Built for 2026 Yahoo/Google sender requirement standards.
  • Enhanced Server Stability
    CloudLinux uses its lightweight virtualization technology (LVE) to isolate each tenant on a shared hosting server, preventing any single user from consuming excessive resources and crashing the server for everyone else. This ensures consistent uptime and performance.
  • Improved Security with HardenedPHP and KernelCare
    CloudLinux offers HardenedPHP, which patches old and unsupported PHP versions against known vulnerabilities, and KernelCare, which provides live kernel patching without requiring server reboots. These features significantly enhance server security posture.
  • Resource Limit Management
    Administrators can set granular resource limits (CPU, memory, I/O, number of processes, etc.) per user account using LVE Manager. This makes it easy to manage shared hosting environments and ensure fair resource distribution among tenants.
  • CageFS File System Virtualization
    CageFS creates a virtualized file system for each user, preventing them from seeing other users on the server, viewing sensitive configuration files, or exploiting server vulnerabilities. This adds an important layer of isolation and security.
  • Wide Compatibility with Hosting Panels
    CloudLinux integrates seamlessly with popular hosting control panels such as cPanel, Plesk, and DirectAdmin, making it straightforward for hosting providers to adopt without overhauling their existing infrastructure or workflows.

Possible disadvantages

  • Additional Licensing Cost
    CloudLinux requires a paid monthly or annual license on top of the base server cost. For smaller hosting providers or individual server owners, this additional expense can add up and may not always be justifiable compared to free alternatives.
  • Limited to CentOS/RHEL-Based Systems
    CloudLinux is built on top of RHEL/CentOS and does not support other Linux distributions like Ubuntu or Debian. This limits its adoption for hosting providers who prefer or already run non-RHEL-based environments.
  • Learning Curve for Configuration
    While CloudLinux provides powerful resource management tools, properly configuring LVE limits, CageFS, PHP Selector, and other features requires a solid understanding of the platform. Misconfiguration can lead to users being unnecessarily restricted or resources being poorly allocated.
  • Potential Performance Overhead
    The additional layers of virtualization, resource monitoring, and file system isolation introduced by CloudLinux can impose a slight performance overhead on the server compared to running a bare, unmodified Linux distribution without these controls.
  • Dependency on CloudLinux Ecosystem
    Adopting CloudLinux means relying on their ecosystem for kernel updates, PHP patches, and security fixes. If the company experiences delays in releasing patches or changes its pricing/licensing model, hosting providers may find themselves locked into a dependency that is difficult to migrate away from.

Questions & Answers

As answered by people managing MailMoxie and CloudLinux.

What makes your product unique?

MailMoxie's answer

Email deliverability has historically been a black box. We make it transparent. While most tools just check if you're on a blacklist, we provide a holistic "Email Governance" score. We are the only platform that treats Accessibility (WCAG 2.1 AA) as a core pillar of deliverability. We believe that if an email isn't accessible to everyone, it isn't truly "delivered".

Why should a person choose your product over its competitors?

MailMoxie's answer

Most tools stop at "Passed" or "Failed." We tell you why it happened and how to fix it using AI-powered insights backed by human expertise. We offer unlimited testing on our paid plans, removing the "credit-based" anxiety of competitors, and provide specialized audits for dark mode, screen readers, and complex DNS alignment that standard tools often overlook.

How would you describe the primary audience of your product?

MailMoxie's answer

We’re built for "Senders of Consequence." This means email marketers, growth teams, and developers who understand that 2026 inbox standards (like those from Google and Yahoo) are stricter than ever. If you manage high-volume campaigns, critical transactional mail, or brand communications that must be inclusive and compliant, MailMoxie is your safety net.

What's the story behind your product?

MailMoxie's answer

MailMoxie was born from over 25 years of high-level deliverability consulting. Our founders spent decades fixing "unfixable" inboxing issues for global brands. We realized that the enterprise-level diagnostics we used were too complex and expensive for most teams, so we built MailMoxie to put that same "Special Ops" power into a self-service dashboard.

Which are the primary technologies used for building your product?

MailMoxie's answer

MailMoxie is a high-performance SaaS platform built to interface directly with global DNS systems and 70+ major blacklist providers. We leverage proprietary AI models to analyze subject line sentiment and deliverability triggers, alongside a "Personal Agent" architecture that allows for real-time, authenticated testing without complex API integrations.

Who are some of the biggest customers of your product?

MailMoxie's answer

MailMoxie is trusted by a wide range of senders, from fast-growing DTC brands to enterprise-level marketing teams.

High-Growth E-commerce Brands

SaaS Platforms (Transactional Mail Security)

B2B Marketing Agencies

Inclusive-First Non-Profits

Fractional Deliverability Specialists
