In this episode, Nathan Wrigley interviews Aurélien Denis about MailerPress, an upcoming WordPress plugin for sending email campaigns directly from your site. Aurélien explains how MailerPress mimics the Gutenberg UI, uses custom blocks for email creation, and integrates features like branding with theme JSON and querying WordPress content (including WooCommerce products). The plugin stores contacts in custom tables and allows flexible email delivery via popular services. They're seeking beta testers and hint at future AI and automation features.
