Product Comparison
IUSign vs Legacy Bulk Send
for Enterprise Document Logistics
Most providers treat bulk-send as a series of individual events. iusign treats it as a single, unified logistics pipeline.
Legacy Bulk Send Typical Flow
Manual field mapping per recipient; high unit cost; limited API support for dynamic data.
- Expensive per-envelope fees
- Massive manual data prep
- Vendor storage liability
IUSign Workflow
CSV-to-Field mapping; API-triggered envelopes; zero-persistence processing.
- Secure CSV injection
- API automation
- Ephemeral data shredding
Impact
Security risk and manual labor reduced to nearly zero.
