Troubleshooting "Invalid Email address" error in BoldSign API

If you encounter the "Invalid Email address" error while using the BoldSign API to send envelopes, it indicates that there is an issue with the email address provided for one of the recipients in your envelope. This error commonly occurs due to incorrect email address formatting or other issues related to recipient email addresses.

Possible causes of the error:

  1. Invalid email format: Ensure that the email address provided follows the standard email format (e.g., ""). Check for any typographical errors, special characters, or missing "@" symbols.

  2. Incomplete Email address: Verify that the email address includes both the username and the domain name.

  3. Incorrect domain: Confirm that the domain part of the email address (e.g., "") is valid and points to a functioning email server.

  4. Typographical errors: Carefully review the email addresses for any typographical errors, including extra spaces, missing characters, or additional characters.

  5. Recipient not registered: Ensure that the recipient's email address is a valid and active email account. If the email address does not exist or is not in use, you may encounter this error.

Troubleshooting steps:

  1. Review recipient Email addresses: Double-check the email addresses provided for all recipients in the envelope. Correct any formatting or typographical errors.

  2. Verify domain: Ensure that the domain part of the email addresses is valid and resolves to an active email server.

  3. Remove special characters: Be cautious with special characters in email addresses, as some systems may not support them. Remove any unnecessary special characters.

  4. Check for whitespace: Ensure that there are no leading or trailing spaces in the email addresses.

  5. Recipient verification: Confirm that the recipient's email address is valid, active, and in use.
