Why Did My Document Fail to Send?

A failed send is almost always one of four causes — check them in this order and you'll be re-sending within minutes. 

1. Invalid Recipient Email 

The most common cause. The form flags malformed addresses (missing @, typos in the domain). Fix the address and retry. Watch for invisible trailing spaces from copy-paste. 

2. Usage Limit Reached 

Glance at the Usage & Plan meter in the top bar. If it reads full — "10 / 10 docs" — sending pauses until you upgrade or your cycle resets. The fix is one click into Settings → My Plan. 

3. File Problems 

Password-protected or corrupted files can't be processed. Remove the PDF password, or re-export the file from its source application, and upload again. 

4. Incomplete Setup 

Every signer needs a name and valid email; ordered flows need every signer assigned a level; every signer should have at least one field. The review step highlights what's missing.
