Bulk Send Best Practices

Cleaning Your Recipient Data

Before launching a bulk send to 1,000+ recipients, ensure your CSV is clean. IUSign provides a pre-flight validation preview to catch malformed emails before the first invitation is sent.

Understanding Signing Orders in Bulk

Our engine supports 'Sender Signs First' or 'Recipient Signs First' modes even in bulk. We auto-inject your signature with unique timestamps for every single document, ensuring each one is a unique legal original.

Rate-Limiting and Deliverability

To avoid being flagged as spam, we process large jobs in batches. This ensuring high inbox placement while maintaining high-speed document logistics.

Take the next step towards document sovereignty.
