Mailster – Email Newsletter Plugin

Description

Mailster manages email marketing campaigns directly from the WordPress dashboard, building newsletters in a visual drag-and-drop editor and sending them via SMTP, Amazon SES, SendGrid, or an internal cron. It’s built for people who publish recurring content on blogs, niche sites, and news portals and prefer to keep subscriber lists, campaign creation, and open reports centralized in the same WordPress install, without relying on an external platform.

Who Is Mailster For?

• Anyone running a blog, digital magazine, or news portal who wants to send periodic roundups to their reader base.
• You, if you already have a subscriber list and want to move sending inside WordPress itself.
• Content creators, info-product sellers, and authors who need to nurture an audience without hiring an external email marketing platform.
• Anyone working in specific niches (courses, communities, ecommerce) who wants to segment campaigns by interest or behavior.

How to Download Mailster

Mailster is available for download here on Ultrapack. After downloading the .zip file, install it via Plugins > Add New > Upload Plugin, select the file, and activate it. Once activation is complete, a new Newsletter menu appears in the WordPress dashboard, where you configure the sending method, create lists, and build your first campaigns.

Centralizing email marketing operations in the same WordPress install avoids constantly syncing lists with external services and removes the variable monthly fee that scales with your list size. Anyone already producing content on their site gets a direct flow: publish, segment the list, and send the campaign without leaving the admin, with reports on the same screen where you edit posts.
