Checking email delivery status (notification types)

You will receive confirmation from AbtracOnLine immediately after an invoice is emailed as to whether it has sent or not.

But it takes a while longer to confirm whether the message has been delivered successfully, received and read.

Email Notifications (Email Activity)

All Email notifications for the sender (Abtrac users)

If there is a problem with any email sent, you will receive a red notification next to your login information within AbtracOnLine. This is at the top right of every page in Abtrac Online.

At the same time, the same message is shown in the Abtrac Message Board in the Homescreen dashboard.

These notifications are only visible for the AbtracOnLine user login that the email was sent from

Clicking on the link associated with the message(s) will take you to the Email Activity screen. Or at any time you can navigate to the same screen from Home > Email Notifications.

Use Email Activity source to filter invoice emails from general correspondence.

To remove a problem email from notifications, you will need to acknowledge the message by clicking on the green tick button indicated below.

The below pop up will appear. Click ‘Yes’ to acknowledge the message and ‘No’ to leave it unacknowledged.

Untick or tick the box indicated below to view all email activity, or ‘Only show undelivered emails not yet acknowledged’ respectively.

All Email notifications for all emails sent from your account (Abtrac administrators)

Regardless of who receives the sender notifications an Abtrac Administrator can view the status of all emails at any time from Home >> Email Notifications.

Email notifications for invoices sent

Any user can view the email status of all invoices sent from the Load invoice screen.

These are the same email status notification types found in more detail from Home > Email notifications.

To enable the email status column in the load invoice screen go to Administration > Settings > User Control Settings, and choose “Invoices – Load”

Email Status: email event notification types, error reasons and send results

Abtrac works with a third party to provide you the best in email deliverability. Abtrac emails are back by the experienced team at Twillo SendGrid, you can learn SendGrid here.

As emails are sent from Abtrac and mail servers and recipients interact with them, a log is stored of the email status. Here is a breakdown of each of the email events and email notification types.

As emails are sent from Abtrac and mail servers and recipients interact with them, a log is stored of the email status.

Here is a breakdown of each of the email events and email notification types.

  • Processed
  • Dropped
  • Deferred
  • Blocked
  • Bounced
  • Delivered
  • Opened
  • Clicked


Each message you send from within AbtracOnLine will create a processed event.


There are a number of reasons your email will not even be sent to a recipient for delivery. This event informs your system when an email has been dropped. Where possible, Abtrac will provide a reason for the drop, such as if we’ve found spam content or if we see the recipient has unsubscribed/blocked your mail.


A deferred event, or deferral, occurs when the server temporarily limits access to its system. It works much like a telephone’s busy signal.

But this doesn’t mean that your message won’t be delivered—only that it won’t be delivered immediately. Some of the most common reasons for a message deferral include:

  • The inbox provider sees too many spam complaints for delivered emails from the sender.
  • The receiving server has technical issues.

When an inbox provider defers your email, Abtrac will continue attempting to deliver your message for up to 72 hours. If your message is deferred for more than 72 hours, that message will be blocked and a block event will be registered. If the message is successfully delivered within the 72-hour window, it’ll register as a delivered event.


Like Deferred emails, bounce-blocked results are emails that are temporarily denied by the server. For these temporary rejections, the receiving server’s reason for refusing the message is unrelated to the sender’s address quality.

Reasons for a blocked email message include:

  • The sending IP or domain is list-denied.
  • There are spam-marked elements within the email content.
  • A technical issue occurred between the 2 servers when you attempted to send your email.


If a server cannot or will not deliver a message, AbtracOnLine fires a bounce event.

Bounces occur when the receiving server returns a code indicating that there’s a permanent issue with that server or the recipient’s address. The most common reason for an email address bounce is that the address in question is invalid. Many times you won’t know a bounced email address until it bounces.


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. The following two events give more information about whether the email has been seen.


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


If your email includes the option click a link (perhaps to your website) Abtrac will track that interaction and fire a click event.

What to do if you have clients not receiving an email sent through Abtrac

Some email hosting providers use high-level email filters, which can delay or prevent genuine emails from being received.

Emails sent from Abtrac often include important financial information, which can occasionally lead to them being mistakenly flagged as spam and routed to junk folders or even rejected altogether.
