Description

Newsletter transforms your WordPress site into a self-hosted email marketing platform, managing subscribers in its own database, creating campaigns in the drag-and-drop editor, and sending newsletters through external SMTP services such as Amazon SES, SendGrid, or Mailgun. Designed for websites, blogs, and stores that want to avoid the per-contact subscription fees charged by SaaS services, it keeps the list, sending history, and open reports hosted locally, with an administrative dashboard within WordPress itself.

Key Features

  • Drag-and-drop email editor
    Builds responsive campaigns by dragging and dropping text, image, button, and divider blocks.
  • Flexible subscription forms
    Provides a widget, dedicated page, and shortcode to capture subscribers anywhere on the website.
  • Integration with professional SMTP services
    Connects to Amazon SES, SendGrid, Mailgun, and other providers through native configuration.
  • Subscriber lists and segmentation
    Organizes the database into lists, custom fields, and segments by preference or language.
  • Performance reports
    Measures opens, clicks, bounces, and unsubscribes with charts for each campaign.

Benefits of Newsletter

  • Predictable sending costs
    Eliminates subscription fees based on the number of subscribers charged by SaaS email services.
  • Full control over your database
    Keeps your contact list hosted in your own WordPress database.
  • Scalability without slowing down your website
    Delegates bulk sending to an external SMTP service, preserving page performance.
  • LGPD and GDPR compliance
    Implements double opt-in, an automatic unsubscribe link, and per-subscriber data exports.

Who Is It For?

  • Blogs and content portals that maintain ongoing relationships with readers via email.
  • WooCommerce stores that send offers, abandoned cart messages, and post-sale communications.
  • Agencies and professionals who manage newsletters for multiple clients across different domains.
  • Companies that need to keep their contact database under their control due to compliance requirements.

For those seeking a self-hosted alternative to SaaS email marketing services, Newsletter covers the entire cycle within WordPress: subscriber acquisition through forms, list segmentation, send scheduling, and open and click analysis. The architecture that separates list management from sending through an external SMTP service makes it possible to manage large databases without overloading the website server or compromising campaign deliverability.
