Resend a Failed Fax with AI

A fax failed? Find it, see why, and resend it from Claude or ChatGPT with the Fax.Plus MCP connector, without opening the app or attaching the document again.

Before you start

• Use an active Fax.Plus Basic plan or higher and an existing authorized Fax.Plus MCP connection.
• Use a compatible client with remote MCP support. These steps use Claude web; interface labels may differ in ChatGPT and other clients.
• MCP is unavailable for accounts with Advanced Security Controls, including HIPAA and PHIPA configurations.
• Confirm that the connection uses the account that sent the fax.

For connection help, see the Fax.Plus MCP setup hub and the client connection guide.

How to resend a failed fax

1. Open a new chat. Use your connected assistant with Fax.Plus available.
2. Find the failed fax. Enter “Show my sent faxes that failed.” The assistant looks through your sent faxes (list-faxes).
3. See why it failed. Ask “Why did the newest one fail?” The record shows the failure with a short reason (get-fax).
4. Ask to resend it. Enter “Resend that fax.” The assistant uses the existing fax as the source (resend-fax: resend using an existing fax as source).
5. Check and confirm. Review the recipient and the sending line, then approve.
6. Check delivery. Ask “Did the resent fax go through?” and get the confirmation report.

Before you confirm

Resending delivers a new, real fax, and a fax cannot be taken back once it is sent. Read the failure reason first: if the number was wrong or unreachable, the same number can fail again. Check the recipient and the sending line, and keep the Fax.Plus resend tool on Needs approval so nothing goes out without your OK.

Example prompts

Copy a prompt into your connected assistant.

Understand the result

After you confirm, the new fax is submitted and the assistant reports its status. Submitted is not delivered: it shows as preparing or sending in the outbox, and moves to your sent faxes when the send finishes. A delivered fax shows the status success. If it fails again, the record shows the reason again.

A repeated failure usually points at the number. In that case get the correct number and send the document as a new fax.

If the resend does not start, the assistant tells you; nothing was sent unless it reports a submission. Check the connection and the account, then try again.

Keep recipient numbers out of shared screenshots.
