Use tool ↗About Newsletrix
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.
