System events are a group of events available to all Exponea customers by default without the need for a specifically-tailored integration. As opposed to custom events, automatic events should be the same for all Exponea users. In this article, we will list and explain the attributes of these events.
session_start happens when the customer visits your website
first_session is derived from the session_start event. It happens when the customer visits your website for the very first time
session_ping is an auxiliary event that will help you track other events. It is generated on every
page_visit and then every 2 minutes while the page is still open in the browser.
session_end is generated 20 minutes after the last
session_ping with a timestamp of the last
session_ping + 30 seconds.
A 'session_start' and 'session_end' (but no 'page_visit') can occasionally be tracked without the customer's actual activity. This can happen when the customer's device is only hybernated and their browser gets active and generates a 'session_ping' without any 'page_visit'.
The duration of the session will be the difference between the timestamps of
session_end in seconds. The timestamp of the
session_end will have a timestamp within 2 minutes after the customer closed the last page (the 20-minute timeout is ignored for the purpose of calculating the session duration).
In other words, the timeout ensures that if someone closes the page but returns within 20 minutes, this will still be counted as a single session. However, if they don't return, those 20 minutes will not be counted into the session duration.

duration (only for session_end)

Customer's location inaccuracies
As all the attributes that localize the customers are based on their IP, they depend on the quality of the IP infrastructure. The
city attributes are generally very reliable, however, the
longitude are often not (as they are a more precise measure of the customer's location).
session_start is often complemented with these manually-added custom attributes.
Number of milliseconds it took to load the page. Read on how to add the attribute to event in the Web tracking article.

Issues with the tracking
If you are using our CDN page outside of your own domain for giving out surveys/getting consent, no
session_start events will be generated.
campaign event is generated when working with emails, text messages, push notifications, or webhooks.
Status of the user's interaction with the campaign mainly based on the SMTP code.
The SMPT code received from a server after you sent out an email.
Name you gave to the campaign.
Automatically-generated ID of the campaign.
Campaign's method of approaching the user.
Name you gave to the specific action within the campaign scenario. In case of emailing through Email campaigns and not scenarios, action_name is the same as campaign_name.
Unique ID number of the action. The number rises proportionally with the order in which you created the action in the scenarios. The action_id of the first action is 1, for the second action it is 2 etc.

Exponea enqueued the email to the email provider
The message was submitted to the network for delivery.
Email provider confirmed delivery
Exponea could not enqueue the email
Communication error between Exponea and the email provider
The email was opened = pixel in the email was loaded.
Note that some services block these pixels, which may result in customers who only have the
clicked event tracked, without
The customer clicked on a link inside the email. This also includes clicking on the unsubscribe link.
Email provider notified Exponea that the customer marked the email as "Spam"
soft_bounced (equivalnt for Mailgun = "failed" for the reasons "old" or "greylisted")
The email provider notified Exponea that the email was temporarily bounced and will try to deliver it again later. A full inbox is among the possible reasons for the error.
hard_bounced (equivalnt for Mailgun = "failed" for the reasons "bounce", "generic" or "blacklisted")
Email provider notified Exponea that the email was bounced with a permanent error.
preblocked (equivalnt for Mailgun = "failed" for the reasons "suppress-bounce", "suppress-unsubscribe" or "suppress-complaint")
The mail service provider had put you on the suppression list and so your emails will not be delivered to the customer.
Email provider notified Exponea that email was rejected for delivery/ The reason might be too many bounces, unsubscription or blacklisting.
Tracking clicked event
Links to your webpage sent out in a campaign firstly lead to our CDN domain so that the
clicked event is tracked. After that, the customer is immediately redirected from the CDN domain to your webpage.
Issues with the opened event
Opened event tracked for Gmail does not guarantee that the recipient had indeed opened your email. Gmail's servers sometimes download external images from emails into their cache in advance. As we use these images to track whether the customers opened the email, we get a fake open event every time Gmail's servers do this. Moreover, email providers sometimes block the loading of the images we use for the tracking of the
opened event so even if your email seems to be just
delivered it might, in fact, be opened.
When an email is bounced, the
email_invalid property is set to
yes`. When `email_invalid` or `unsubscribed` is set to `true`/yes`, Exponea won't send emails to those customers, even if they satisfy all other conditions, hence using these attributes manually in conditions is not necessary. This serves to prevent undeliverable emails from being sent, protecting the sender's reputation and spam score. Learn more about how unsubscribing works in the campaign groups article.
Statuses of the
campaign event are based on the SMTP error codes received. SMTP error codes starting with 4xx are marked as
dropped, while error codes 5xx stand for
bounced. However, some providers send 5xx marked as
dropped. In these cases, Exponea treats them as bounced emails.
Code attribute gives you the SMPT error or reply code received from a server after you send out a campaign email. The
status attribute is based on these codes, however, it is useful to also know the code itself as it is more precise in assessing what happened to the email. The following link contains a list of codes and their corresponding meanings. For these to work correctly, you need to have a Mailgun integration. Even though SMPT codes are reliable for most customers, beware that small email providers often send alternative SMPT codes that will not be recognized.
