Email marketing remains one of the most effective ways to engage your audience. While external services often come with high monthly fees and subscriber limits, MailerPress (v1.5.x in 2026) allows you to run a professional newsletter system entirely from your WordPress dashboard.
For mybox users, MailerPress offers a high-performance, self-hosted solution that keeps your data secure on your own server while providing a modern, block-based design experience.

What is the MailerPress Plugin?
MailerPress is a specialized email marketing tool that integrates seamlessly with the WordPress environment. Unlike plugins that simply “connect” to an external service, MailerPress handles the creation, list management, and campaign tracking directly within your site.
- Familiar Interface: The email editor is inspired by the WordPress Block Editor (Gutenberg), so if you can build a page, you can design an email.
- Data Sovereignty: Your subscriber lists are stored in your mybox database, ensuring you have full control over your audience data and GDPR compliance.
- Full Site Editing (FSE) Ready: It uses
theme.jsonsupport to ensure your newsletters automatically match your website’s colors and typography.
Key Features of the Free Version
The free version of MailerPress is remarkably generous, making it an excellent choice for growing sites:
- Unlimited Everything: There are no limits on the number of contacts, lists, tags, or campaigns you can create.
- Drag-and-Drop Editor: Build professional layouts with a visual interface.
- Content Retrieval: Easily pull existing content from your site-such as your latest blog posts or specific pages-directly into your newsletter.
- Privacy & Compliance: Built-in double opt-in mechanisms, customizable confirmation emails, and automatic unsubscribe links keep your emails professional and legal.
How Emails are Sent
It is important to understand that MailerPress is the “designer” and “manager,” but it needs a “delivery truck” to send the messages.
- Standard Sending: By default, it can use the native PHP Mail function of your mybox hosting. This is fine for small lists but can lead to emails landing in spam folders as your list grows.
- Custom SMTP: You can configure the plugin to use an external SMTP server for better deliverability.
- Professional Mailers (Paid): The Pro version adds native integrations with high-volume delivery services like SendGrid, Brevo, Mailjet, and Amazon SES to ensure your newsletters reach the inbox every time.
2026 AI Features
In the latest 2026 updates, MailerPress has introduced AI-Powered Marketing modules. These tools can help you:
- Optimize Content: Rewrite subject lines for better open rates.
- Generate Visuals: Create unique images for your campaigns using integrated AI image generators.
- Automate Summaries: Automatically turn your long blog posts into concise email teasers.
Step-by-Step: Getting Started
Setting up your own newsletter system on mybox takes only a few minutes:
- Installation: In your dashboard, go to Plugins > Add New. Search for “MailerPress”, install, and Activate.
- Initial Configuration: Navigate to the new MailerPress tab in your sidebar. Follow the setup wizard to define your “From” name and email address.

- Draft Your First Campaign: Click Create Campaign. You can start with a pre-built template or use the block editor to build a custom design.
- Test and Send: Always send a test email to your own inbox first to check the layout on mobile and desktop before sending it to your entire list.
Summary
MailerPress is a “game-changer” for WordPress users who want to avoid the high costs of external platforms. By hosting your newsletter system on mybox, you gain a powerful, modern, and private marketing tool that grows alongside your business.
