MailDeck 2 features

CloudLinux 5 features

100 inboxes per domain
1 Outlook tenant = 100 inboxes
Automated DNS configuration
DKIM, SPF, and DMARC

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 MailDeck and CloudLinux.

Who are some of the biggest customers of your product?

MailDeck's answer

B2B SaaS companies running outbound sales Lead generation agencies managing multiple client campaigns Recruitment firms doing high-volume candidate outreach Growth agencies handling outbound for portfolio companies Sales teams at fintech and real estate companies

What makes your product unique?

MailDeck's answer

MailDeck combines Google Workspace, Microsoft 365, and SMTP providers into a single infrastructure platform. Unlike tools that only handle one provider, MailDeck gives you unified management with automated DNS setup - no manual configuration of SPF, DKIM, or DMARC. It's built specifically for cold email at scale, not repurposed from marketing tools.

Why should a person choose your product over its competitors?

MailDeck's answer

MailDeck focuses on reliability at high volume. Where other providers start having deliverability issues as you scale, MailDeck maintains consistent inbox placement even at millions of emails per month. The zero-configuration setup means you're operational in minutes. Plus, it integrates with any sequencer you're already using.

How would you describe the primary audience of your product?

MailDeck's answer

B2B outbound teams who send at scale - SDRs, sales teams, lead generation agencies, growth agencies, and recruitment firms. Typically teams sending 100K+ emails per month who've outgrown basic Google Workspace setups and need infrastructure that won't collapse under volume.

Which are the primary technologies used for building your product?

MailDeck's answer

MailDeck integrates directly with Google Workspace and Microsoft 365 APIs, along with custom SMTP infrastructure. The platform handles automated DNS management, real-time deliverability monitoring, and smart routing across multiple providers.
