Find the message in your workspace. A successful API response confirms receipt, not that a notification reached a mailbox.
Notifications have their own delivery states. See where the message was routed and what happened to each send attempt.
Read the failure details, check the recipient, and use the message’s retry control when available. Retrying is a new attempt, not a delivery guarantee.
| Status | What it tells you |
|---|---|
| Queued | The notification is waiting for an email attempt. |
| Sending | An attempt is in progress. |
| Accepted by email service | The provider accepted the send request; recipient delivery is not yet confirmed. |
| Delivered to mail server | The receiving mail server accepted it. This does not prove inbox placement or that it was read. |
| Bounced | The notification could not be delivered. Inspect the failure details and recipient. |
| Needs attention | An attempt needs review. Inspect the history before using the available retry control. |
The message gives you a starting point for investigation. If the notification was delivered to the mail server, check the recipient’s spam folder and mailbox rules too. Read about receipt and delivery.
Frequently asked questions
Yes. The submission inbox and notification delivery status are included in both Free and Pro.
No. Delivered to mail server means the receiving server accepted the email. Form Koi does not turn that state into a claim about inbox placement or whether someone read it.
No. Submission storage and notification delivery are separate. The message remains subject to your retention settings and deletion actions.
The message page provides retry controls for eligible failures. Inspect the attempt history and address issues such as an incorrect recipient first. A retry may still fail if the cause has not changed.
