Limitations of Using Mailster

Although Mailster is a powerful WordPress newsletter plugin, it does come with some limitations worth considering. Here are the key drawbacks:

• Dependent on Your Hosting Server – Since Mailster is self-hosted, deliverability and performance depend heavily on the quality of your hosting and server resources.
• Requires SMTP Setup for Best Results – To achieve high inbox placement, you must configure an SMTP service like Amazon SES or SendGrid, which adds an extra step for beginners.
• No Native Email Deliverability Guarantee – Unlike SaaS platforms, there’s no built-in infrastructure to ensure deliverability — it relies on your chosen mail service.
• Learning Curve for New Users – Users unfamiliar with WordPress or email marketing may need time to understand list management, automation, and segmentation.
• Limited Built-In Integrations Compared to SaaS Tools – While it integrates with popular WordPress plugins, some external CRM or advanced marketing tools may require manual setup or custom solutions.
• Potential Performance Issues on Shared Hosting – Large email lists can slow down your website if the server lacks resources or is not optimized.
• No Dedicated Cloud-Based Dashboard – All campaign management happens within WordPress, which may be limiting for teams used to standalone SaaS dashboards.

Mailster vs Competitors

When comparing Mailster to SaaS tools like Mailchimp, ConvertKit, or ActiveCampaign, several differences stand out. Below is a comparison sorted by the most crucial factors for businesses:

• Pricing Model – Mailster offers a one-time payment, while competitors typically charge monthly fees that grow as your list size increases.
• Data Ownership & Privacy – With Mailster, you fully control subscriber data on your own server, unlike cloud-based competitors that store data externally.
• Customization & Flexibility – Mailster integrates directly with WordPress and allows deeper customization, whereas SaaS tools have a fixed dashboard with limited design control.
• Scalability – SaaS platforms handle infrastructure and deliverability at scale, while Mailster relies on your server capacity and configuration.
• Deliverability Support – Competitors offer managed deliverability and IP reputation services, while Mailster requires you to configure your SMTP or transactional email provider.
• Ease of Use – Mailchimp and ConvertKit may feel more beginner-friendly, whereas Mailster is ideal for users comfortable with WordPress.
• Integration Ecosystem – SaaS tools have hundreds of ready-made integrations, while Mailster focuses on WordPress-centric integrations like WooCommerce and form plugins.
• Team Collaboration & Cloud Access – Platforms like ActiveCampaign offer multi-user cloud dashboards, while Mailster restricts collaboration to WordPress user roles.
• Automation Depth – Advanced tools like ActiveCampaign offer complex automation workflows, whereas Mailster focuses on essential autoresponders and campaigns.

Before installing Mailster, it’s essential to ensure that your website meets the basic technical requirements. Meeting these standards guarantees smooth performance and prevents delivery failures.

• WordPress Version – Requires WordPress 5.0 or higher for full compatibility and security.
• PHP Version – Needs PHP 7.4 or above (PHP 8.0+ highly recommended) for faster processing and better stability.
• MySQL or MariaDB – At least MySQL 5.6+ or MariaDB 10+ to properly store subscriber data and campaign logs.

Recommended Hosting Specification for Mailster

To get the best results, especially if you run high-volume campaigns, choosing the right hosting is crucial. A well-optimized environment ensures faster delivery and fewer email bounces.

• SMTP Compatibility – Make sure your host allows external SMTP connections to services like Amazon SES, Mailgun, or SendGrid for reliable email delivery.
• Daily Email Limit – Choose a hosting provider that does not restrict outgoing email too heavily, or rely on a third-party SMTP for unlimited sends.
• Dedicated Resources – For lists over 10,000 subscribers, use hosting with dedicated CPU and RAM to avoid delays during campaign processing.
