Mailing tracking | SMTP Activity

The Activity tab allows you to view the history of emails sent via the Cyberimpact SMTP Relay and track their delivery status, recipient by recipient. After reading this article, you will know how to navigate this section and interpret the information displayed.

What it's used for

The Activity tab is useful for:

Confirming that an email was sent and delivered
Quickly identifying a delivery issue on a specific mailing
Tracking the status of a transactional email reported as not received by a recipient

Before you begin

Have an active SMTP plan on your Cyberimpact account
Have the required permissions: the Activity tab is accessible to administrators, regular users, and custom users with the Access SMTP activities permission
The Activity tab displays email activity from the last 30 days.

How it works

Each row in the Activity tab corresponds to one recipient, not one message. If an email was sent to 5 recipients, it will appear on 5 separate rows, each with its own delivery status.

By default, the period displayed covers the last 30 days. The dates and times displayed correspond to the time zone configured on your account.

Refine the displayed period using the date selector — choose from quick shortcuts (Today, Yesterday, Last 7 days) or define a custom date range based on your needs.

For each row, you can view:

The date and time of the mailing
The delivery status
The recipient's address
The email subject
The sender's address

For the Rejected, Deferred, Soft bounce, and Hard bounce statuses, hover over the status label with your mouse to display the reason for the issue directly in the list.

Step by step

Log in to your Cyberimpact account and access the SMTP section via the main navigation menu.
Click the Activity tab.
Browse the list of mailings: each row corresponds to a recipient. Scroll through the list to find the message you are looking for.
Filter the results as needed using the date selector or advanced search to refine by recipient, sender, subject, or a specific period.

Understanding delivery statuses

Status	What it means
Rejected	The message was not accepted by the server before sending. Possible causes: invalid address, SMTP sending quota reached on your account, or unauthenticated domain.
Accepted	The message was received and accepted by Cyberimpact's server.
Pending	The message is in the sending server's queue, waiting to be transmitted to the recipient.
Delivered	The message was accepted by the recipient's server.
Deferred	A temporary error occurred — the system will automatically retry delivery.
Soft bounce	Delivery failed after several attempts due to a temporary cause.
Hard bounce	Delivery failed permanently, usually due to an invalid or non-existent address.

The Delivered, Soft bounce, and Hard bounce statuses are final on the SMTP relay side.

Note: an email displayed as Delivered may subsequently change to a soft or hard bounce. Some servers initially accept the message, then send a non-delivery notification afterward. In that case, the final status is automatically updated in your mailings statistics (on the dashboard), but you will still see the "Delivered" activity followed by the bounce in your email activity.

Tips and tricks

A recipient says they did not receive the email
Search for their address in the Activity tab to check the status. If it shows Delivered, the message was accepted by their mail server — the issue may be a spam filter on their end. If it shows Deferred, Soft bounce, or Hard bounce, refer to the article Understanding email statuses for next steps.

Data available for 30 days by default
The default period displays the last 30 days. Use the date selector to view an earlier period as needed.
