seenbase

seenbase is an open-tracking analytics platform that generates lightweight tracking pixels to monitor when emails, PDFs, proposals, CVs, and documents are opened. Unlike Google Analytics, which stops at the website door, seenbase reveals which companies opened your files and from where, without requiring cookies, browser extensions, or JavaScript.

Key features include real-time pixel feed with location and company network data, server-side population of visitor information, and the ability to track opens across emails, PDFs, LinkedIn links, and shared documents like Notion pages and Substack posts. The platform captures metadata including timestamp, geographic location, network/company, device information, and referrer data for each open.

seenbase is ideal for sales professionals, recruiters, freelancers, and businesses who need to understand engagement with their outreach materials. It offers a free tier covering 1,000 opens per month with no credit card required, making it accessible for side projects, cold outreach campaigns, and document sharing.
