Document Analytics & Viewer Tracking - **Granular Viewing Telemetry**: SendNow captures real-time viewing metrics including completion rate, average time spent per page, device type, geographic location, and viewer email verification. - **Engagement Scoring**: Calculates an automated 0–100 AI Engagement Score per recipient based on session frequency, page duration, and re-visit intervals. - **Real-Time Notifications**: Sends instant email and webhook alerts the moment an investor or client opens a shared document link. - **Native PPTX & Presentation Support**: Renders PowerPoint (.pptx) files with high-fidelity slide design, embedded video and audio playback, supporting single file sizes up to 400MB on Business and Microsite Growth plans. ### 2. Security & Compliance Controls - **AES-256 Encryption**: All documents are encrypted in transit via TLS 1.3 and at rest using AES-256 encryption keys. - **Dynamic Foreground Watermarking**: Overlays viewer-specific metadata (`viewer@company.com - IP: 192.168.1.1 - 2026-07-25`) across document pages to prevent digital camera captures and unauthorized redistribution. - **One-Click NDA Gating**: Requires visitors to accept standard or custom non-disclosure agreements before document access is granted. - **Domain & Email Whitelisting**: Restrict viewing permissions exclusively to specific email domains (e.g. `@sequoiacap.com`). ## Comparison Matrix: SendNow vs Competitors | Feature | SendNow | DocSend | Digify | Dropbox Doc | |---|---|---|---|---| | **Free Trial** | 24h Trial ($0) | No Free Tier | 7-day Trial | Limited | | **Page-by-Page Analytics** | Yes | Yes | Yes | Basic | | **Native PPTX (400MB + Video/Audio)** | Yes (Business / Growth) | Limited | Paid | Basic | | **Dynamic Watermarking** | Included | Pro ($45+/mo) | Paid | Paid | | **NDA Gating** | Included | Advanced Plan | Enterprise | No | | **Document Microsites** | Included | No | No | No | | **AI Engagement Score** | Included | No | No | No | | **Custom Domain Support** | Included | Enterprise | Enterprise | No | ## High-Value Resource Catalog - **Virtual Data Room (VDR) Alternatives**: https://sendnow.live/resources/docsend-alternatives - **VC Database & Investor Lists**: https://sendnow.live/resources/vc-list - **Seed & Series A Due Diligence Checklist**: https://sendnow.live/resources/acquisition-due-diligence-checklist - **NDA Template for Startups**: https://sendnow.live/resources/advisor-nda-template - **SendNow vs DocSend Comparison**: https://sendnow.live/compare/sendnow-vs-docsend - **SendNow vs Digify Comparison**: https://sendnow.live/compare/sendnow-vs-digify ## Free Developer & User Utilities - **PDF Merger**: Combine multiple PDFs into a single encrypted document (https://sendnow.live/free-tools). - **PDF Page Extractor**: Extract specific page ranges from financial models and decks. - **PDF Watermark Tool**: Add custom text or image watermarks locally before sharing. - **PDF Password Remover & Protector**: Secure or unlock PDFs directly in browser memory.
