Newsletrix is an AI-powered newsletter competitor intelligence platform that analyzes any newsletter you receive - including competitor Substacks - via IMAP. Substack Analytics is the native dashboard built into the Substack publishing platform, showing your own publication's subscriber counts, open rates, and paid conversions. Substack Analytics tells you how your own readers engage; Newsletrix tells you what competitors in your niche are doing and how they compare.
Substack Analytics is the native analytics dashboard included in every Substack publication. It shows subscriber growth over time, free vs. paid subscriber counts, open rates and click rates for individual posts, paid subscription revenue, and reader retention metrics. All data is scoped to your own publication - you cannot view any data about other Substack writers or newsletters from other platforms. For writers who want to understand competitor newsletters or benchmark their content against others in their niche, Substack Analytics provides no useful data.

Common questions about choosing between Newsletrix and Substack Analytics
Substack Analytics is your own publication dashboard - it shows how your readers engage with your posts. Newsletrix is a competitive intelligence platform - it ingests any newsletter via IMAP and runs AI scoring on subject lines, CTAs, SWOT, readability, and deliverability. Different data, different purpose.
No. Substack Analytics is entirely restricted to your own publication. You cannot view any data about other Substack writers, their subscriber counts, open rates, or content patterns. Newsletrix was built specifically to fill that gap.
Yes, as long as you have a subscription and receive the issues in your inbox. Newsletrix ingests whatever arrives in your connected IMAP inbox. Paid or free, Substack or otherwise - if it lands in your inbox, Newsletrix can analyze it.
Yes. Newsletrix checks SPF, DKIM, and DMARC authentication records for every tracked sender automatically, including Substack-hosted newsletters. Substack Analytics does not surface deliverability authentication data at all.
No. Newsletrix works with any newsletter from any platform via IMAP - Substack, Beehiiv, Mailchimp, ConvertKit, custom ESPs, and more. It does not care about the sending platform; it analyzes the content that arrives in your inbox.
Yes. Newsletrix has a free tier with limited analyses per week so you can evaluate competitive intelligence before committing. Paid plans start at $9/month. No credit card required to start.
The competitive intelligence layer Substack does not provide
Substack Analytics shows you your own metrics in isolation. Newsletrix shows you what competing newsletters in your niche are doing - their subject line scores, send cadence, CTA patterns, and SWOT tags. That context transforms your own Substack data from interesting to actionable.
Every competitor newsletter that arrives in your inbox gets automatically scored on subject line quality, readability, sentiment, CTA friction, and SWOT. No manual review required - the analysis is already in the dashboard by the time you check it.
Your competitors do not all use Substack. Newsletrix analyzes newsletters from any platform - Substack, Beehiiv, Mailchimp, ConvertKit, custom ESPs. One dashboard covers your entire competitive set regardless of how they send.
SPF, DKIM, and DMARC authentication checks run automatically for every newsletter sender you track. Substack Analytics does not surface this data at all. If a competitor has authentication gaps that affect deliverability, Newsletrix flags it.
PDF export turns the structured competitive analysis into a shareable document. Writers and content strategists use it for weekly competitive reviews and to identify positioning opportunities in their niche.
Start with AI-powered competitor analysis at $9/month with a free tier included. Substack Analytics is free but limited to your own publication data. At $9/month, Newsletrix adds the competitive layer that Substack does not provide.
