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.
