When an email by Sydnee is sent, we track events during the email sending process.

These events are extremely helpful when trouble shooting email deliverability issues.

This feature was launched on December 10th, 2024 so any emails sent before this date will have incomplete event tracking.

Navigate to https://my.sydnee.app/settings/email/history to see a history of all emails sent on behalf of Sydnee.

There are 9 kinds of events that can show up here. If you see another type, please reach out to support so we can investigate.

This event fires when our mailer receives an individual message and prepares it to be delivered. Think of this as the top of the funnel-unless it is dropped (see below), each message we pushed out will create a processed event. Often times this event happens nearly at the same time as other events, causing it to appear out of order.

There are a number of reasons your email will not even be sent to a recipient for delivery. This means that despite configurations being correct, we cannot deliver the email. Please contact support if your emails are being dropped so we can investigate. Chances are your client has unsubscribed from receiving emails.

When an email cannot immediately be delivered, but it hasn’t been completely rejected, the deferred event fires. Sometimes called a soft bounce, we will continue to try for 72 hours to deliver a deferred message. After 72 hours, the deferral turns into a block.

If a server cannot or will not deliver a message, our mailing system fires a bounce event. Bounces often are caused by outdated or incorrectly entered email addresses. Many times you won't know a bounced email address until it bounces, so this event can help you ensure it doesn’t bounce again by adjusting your setup.

When an email has been accepted at the receiving server, the delivered event fires. This event does not guarantee that the email was placed in the recipient’s inbox. In fact, a delivered email is only the beginning of an opaque process. The remaining four events begin to give us hints about whether anyone will ever see this delivered email.

This event fires every time your email is viewed with images turned on. Like all email service providers, we use a transparent image beacon to track opened messages. This beacon is currently the only way a sender can tell if an email has been opened.

A link in the email has been clicked.

Most Internet Service Providers (ISPs) provide a feedback loop, sending specific spam complaints to the Email Service Providers (ESPs), like Sydnee. When Sydnee receives a notice, we fire a spam event, so that you can react appropriately—or at the very least, never send another email to that address! We will block all further outreach if this happens. Please contact support if this was not on purpose.

If a user no longer wants to receive emails from Sydnee, they can unsubscribe and further emails will be "dropped". We group some of our email types, so if you see "Group_unsubscribe" then it means the person has only been removed from that type of email usually.
