Newsletrix is an AI-powered newsletter intelligence platform that analyzes newsletters from any IMAP inbox and returns structured scoring on subject lines, CTAs, sentiment, SWOT, readability, and deliverability. Milled is a public search engine for marketing emails that indexes millions of emails from thousands of retail and DTC brands, allowing users to search by keyword, brand, or category for free.
Milled is a free public email search engine that archives marketing emails from thousands of retail and DTC brands. Users can search by keyword, browse by brand, or filter by category to find email campaign examples for design inspiration.
