seenbase

seenbase is an open tracking analytics platform that generates lightweight tracking pixels to monitor when emails, PDFs, proposals, CVs, and other documents are opened. Unlike traditional analytics tools that stop at website doors, seenbase reveals which companies opened your documents, their location, device information, and network details—all without requiring cookies, browser extensions, or JavaScript.

Key features include real-time pixel feed with live event tracking, server-side data population, and the ability to track opens across email, PDFs, LinkedIn shared links, Notion pages, Substack, and README badges. The platform captures metadata such as timestamp, geographic location, company network, device type, and referrer information for each document open.

seenbase is ideal for sales professionals, recruiters, and business development teams who need to track engagement with cold emails, proposals, CVs, and whitepapers. The platform offers a generous free tier with 1,000 tracked opens per month, requiring no credit card to get started.
