Spreadsheet Datasets

Paced Anti-Spam Sending

Result: Every recipient gets their own personalized document and email with maximum inbox deliverability.
Why traditional batch sending was broken
Personalized documents and emails shouldn't require hours of tedious copy-pasting or fragile developer scripts.
- ✕Copying names from spreadsheets into individual emails by hand
- ✕Re-editing canvas documents for every single recipient
- ✕Risking email blacklists by blasting thousands of emails at once
- ✕Manually reconciling which recipients received which document
- ✕Juggling disconnected tools for design, data, and dispatch
- ✓Automatic column-to-token {{variable}} mapping from any spreadsheet
- ✓Sub-15ms on-the-fly personalized PDF, PNG & SVG generation
- ✓Configurable anti-spam chunk sizing, delays, and pacing rest pauses
- ✓Automated per-recipient delivery ledger with retry recovery
- ✓All-in-one visual canvas, data importer, and custom relay dispatcher
