## What Newsletrix is

Newsletrix is a SaaS competitor-intelligence tool focused exclusively on email newsletters. Users get a unique forwarding address, subscribe to any competitor newsletter, and Newsletrix analyzes every send within minutes. There is nothing to install and no integration with sending platforms (Substack, Beehiiv, Mailchimp, ConvertKit, Klaviyo, custom in-house tools) is required - if a newsletter lands in an inbox, Newsletrix can analyze it.

## Problem solved

Newsletter creators and marketing teams typically have:

- Limited engagement metrics on their own sends and zero visibility into competitors.
- Manual, time-consuming competitor research using spreadsheets and screenshots.
- Vague best-practice advice that is hard to apply to a specific niche or audience.

Newsletrix replaces this with structured, AI-extracted intelligence on every competitor newsletter the user tracks.
