By understanding these metrics and what they indicate about your message delivery, you can refine your approach and achieve better results.
- SMS:
- Pending: The SMS has been queued and is waiting to be processed.
- Sent: The SMS has been accepted by the carrier and sent to the recipient's device.
- Delivered: The carrier has confirmed that the SMS was successfully delivered to the recipient's device.
- Undelivered: The carrier was unable to deliver the SMS to the recipient's device and has stopped trying.
- Failed: The SMS delivery has failed due to an error, such as an invalid phone number or network issue.
- Received: The recipient's device has received the SMS. Note that this does not necessarily mean that the recipient has read the SMS.

- Sent: The email has been accepted and sent to the recipient’s mail server.
- Delivered: The receiving server accepted the message.
- Deferred: The receiving server delayed acceptance of the message.
- Blocked: The receiving server denied the message, but SendGrid won’t suppress the email address.
- Bounced: The receiving server denied the message, and SendGrid will suppress the recipient’s email address going forward.
- Processed: The email has been processed by the recipient’s mail server. This status does not indicate whether the email was delivered to the recipient’s inbox or not.
- Dropped: The email has been dropped and will not be delivered to the recipient’s mail server. This could be due to a variety of reasons, such as an invalid email address or a suppressed email address.
