# See whether an invoice was delivered or opened

See whether an invoice email was sent, delivered, delayed, or bounced, and whether the invoice link was opened.

## Open the delivery timeline

1. Open **All pages** in the left sidebar, then click **Sales** and [**Invoices**](https://app.booksgpt.ai/go/invoices), and open the invoice.
2. The timeline is the invoice's **Activity** section. On a wide screen it is beside the invoice. On a narrower one, click the **Activity** tab under the invoice.

Or, on the Invoices list, point at a row and click **View activity** to open the same timeline.

The timeline is newest first. Filter it with **All**, **Document**, **Books**, or **Delivery**.

## Email delivery and link opens

Choose **Delivery**. Each send keeps one line, and the title is the latest news about that send. The status on the invoice is a different fact: **Sent** means it was emailed, and **Link opened** means the link was opened. Neither one means the mail server accepted it.

- **Invoice sent** records that you sent it.
- **Invoice email sent** means it was accepted to go out. Delivery is not confirmed yet.
- **Invoice email delivered** means the recipient's mail server accepted it. It can still land in spam.
- **Invoice email delayed** means delivery is taking longer.
- **Invoice email bounced** means it came back. Check the address, then open **More invoice actions** on the invoice and choose **Send again**. On the Invoices list, the row's **Send invoice** shortcut opens the same send window.
- **Invoice email reported as spam** means it was marked as spam.
- **Payment reminder sent** is a reminder. It is not another copy of the invoice email.

The line under a delivery event names the version, how many recipients, and the subject. If the send carried files, it also names how many attachments. If it starts with **Latest delivery status checked**, that status was filled in by a later check. The time on that line is when the check ran. The Invoices list does not say delivered, delayed, bounced, or spam.

## Link opened

**Link opened** does not prove a person read the invoice. Email security scanners can open the link.

- On the Invoices list, the status reads **Link opened**. Point at it to see when the invoice was sent and when the link was opened.
- In Activity the event is **Invoice link opened**, and the name beside the time is **Invoice link**.
- To list only these invoices, click the funnel at the right end of the tabs (**Filter invoices**), then under **Status** choose **Link opened**. It appears only when an invoice in the open tab has that status.

## If a send failed

If a send failed and the invoice is still **Final · not sent** (posted, not emailed yet), the line under the header says **Posted to A/R. Delivery failed** and tells you to see Activity. That event is **Invoice delivery failed**.
