MailerLite Newsletter (Joomlax) is a site module that displays a name and email signup form wherever you place it. Submissions are sent to MailerLite using their current REST API. Unlike client-side integrations, this module calls MailerLite from your server through Joomla’s com_ajax interface, so your API token never appears in page source or JavaScript — a better fit for production sites and privacy-conscious projects.

No core hacks. Install the module, paste your API token and audience group ID (with help from the built-in Setup instructions tab and official MailerLite links), tune appearance to match your template, and publish.

Key Features

Secure subscription flow
- Server-side POST to MailerLite with Bearer token stored only in module parameters
- CSRF protection on Ajax requests
- Optional custom API endpoint (defaults to official subscribers URL)

Editor-friendly content
- Heading, intro text, field placeholders, button label, success and error messages — all configurable per module instance

Layout & design
- Horizontal or vertical layout (responsive breakpoints included)
- Colours, font sizes, inputs, button (normal and hover), border radius, section padding, content max width
- Optional button icon: none, arrow, envelope, or paper plane (inline SVG)

Multilingual-ready
- Language files for **MOD_*** strings; duplicate the module per language for translated form copy (standard Joomla workflow)

Developer-friendly markup
- jx- prefixed CSS classes to reduce collisions with templates and third-party CSS

Maintained for current Joomla

- GNU GPL v2 or later
