Introduction
LetterPress Pro is the premium extension for the free LetterPress plugin. It installs as a separate plugin on top of the free one and adds two things:
- AI email generation. Describe a campaign and get a complete, styled email in the builder. See AI Email Generation.
- Plugin integrations. Branded transactional templates for WooCommerce, forms, memberships, and LMS plugins, each with its own variables and events. See Integrations.
How it installs
- Install and activate the free LetterPress plugin first. Pro requires it.
- Install the LetterPress Pro plugin zip through Plugins > Add New Plugin.
- Activate it. Pro features appear inside the LetterPress admin immediately: the Write with AI action in the builder, the AI tab in Settings, and integration events in the Transactional tab.
Pro never modifies the free plugin's screens. It registers through the same hooks and filters the free plugin publishes, so updating either plugin stays safe.
What stays free
Everything in the free plugin stays free: the visual builder, campaigns, subscribers, groups, sources, transactional templates for WordPress events, SMTP and provider delivery, and the REST API. Pro layers on top without paywalls inside those features.
