As answered by people managing Postalion and Jackmail.
Postalion's answer
It is a complete newsletter tool that runs inside your own WordPress, with no outside account and no limit on subscribers or emails in the free plugin. Your list stays in your database, statistics are counted on your server, and nothing is sent to outside services unless you choose a sending service yourself.
Postalion's answer
Hosted services like Mailchimp charge more as the list grows and keep your subscribers on their servers. Other WordPress plugins often cap subscribers or sends in their free version. Postalion has no such limits, imports your list from Mailchimp, MailPoet or the Newsletter plugin in a few clicks, and works with the plugins you already run: WooCommerce, course and membership plugins, donation and form plugins.
Postalion's answer
WordPress site owners who want to send newsletters without a monthly bill: bloggers, small shops, course creators, membership sites, nonprofits, local businesses and agencies that build sites for them.
Postalion's answer
It started as a plugin for a single site and grew into a full newsletter tool. It is made by Alex Gurghis at FantasyThemes and was released on WordPress.org in October 2026. The free plugin stays complete; an optional add-on, Postalion Pro, funds its development.
Postalion's answer
PHP and the WordPress APIs, with its own database tables for subscribers, lists and the email log. Sending runs in the background in batches through WP-Cron, via the site's mail function or any SMTP service. The sign-up form is a native block for the block editor, with elements for Elementor, Beaver Builder, Bricks and Divi.
