Tracks competitor email newsletters and scores their subject lines, CTAs, and sentiment automatically.
Newsletrix tracks newsletters sent by competitors and scores each send on its subject line, call-to-action, readability, and sentiment, rolling the results up into a SWOT analysis, a heatmap of when competitors send, and keyword trends over time. It works with newsletters built on Substack, beehiiv, Mailchimp, ConvertKit, Klaviyo, SendGrid, and HubSpot, or really anything delivered by email, and offers an MCP connector so the data can be queried from ChatGPT, Claude, or Cursor. A free plan covers two analyses a week; paid plans start at 9 dollars a month for five analyses a week and scale up to a 69 dollar a month tier for fifty.

Use tool ↗Newsletrix is genuinely useful for a marketing team that wants to see what competitor newsletters are doing without manually subscribing to and reading each one. The free tier's two analyses a week is enough to sanity-check the scoring approach before committing to a paid plan.
