Possible disadvantages
Cost For smaller businesses or individuals, the pricing might be higher compared to some other email services, which can be a barrier for those with limited budgets.
Complexity While powerful, the range of features and options might be overwhelming for users who are not experienced with email marketing platforms.
Learning Curve New users might face a steep learning curve in understanding and fully utilizing all the features provided by SMTP.com.
Support Some users have reported that support responses can be slow, particularly for non-enterprise clients, which might affect the speed at which issues are resolved.
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.

Phplist is free, then you will need to plug that into an SMTP relay like smtp.com or sendgrid.com.
