Metrica

Description

When increases

Email delivery

Sent

Number of emails Yandex Cloud Postbox accepted for delivery.

Yandex Cloud Postbox accepts an email for delivery.

Delivered

Number of emails successfully delivered to the recipients' mail servers.

Yandex Cloud Postbox gets a confirmation from the recipient's email server that the email was accepted.

Not delivered

Number of emails not delivered to the recipients' mail servers.

Yandex Cloud Postbox gets notified by the recipient's email server that the email cannot be delivered, or that the email is not delivered within a particular time.

Engagement

Openings

Number of emails opened by recipients.

Yandex Cloud Postbox gets notified that the email was opened.

Only emails with open tracking on are counted. If the recipient opens the same email multiple times, the metric increases by the same number of opens.

Clicks

Number of email clicks.

Yandex Cloud Postbox gets notified about an email click.

Only emails with click tracking on are counted. If the recipient clicks the same link multiple times, the metric increases by the same number of clicks.

Negative feedback

Complaints

Number of complaints about emails

Yandex Cloud Postbox receives an email-related complaint from an internet service provider (ISP).

Unsubscribes

Number of unsubscribe requests.

Yandex Cloud Postbox receives an unsubscribe request from the recipient.

Note

When viewing detailed statistics by time, all email events are grouped into the time interval in which Yandex Cloud Postbox accepted the email for delivery.

Viewing statisticsViewing statistics

You can view your sent email statistics on the Statistics page in the management console.

Filtering by configurationFiltering by configuration

The way data is grouped depends on the selected statistics level. In general folder statistics, the chart groups data by sender address. In statistics for a specific address, the chart groups data by configurations used to send messages from that address.

For example, if you send both transactional emails, such as email verification or password reset messages, and marketing campaigns from the same domain, create separate configurations named transactional and marketing. These configurations can have the same settings. Yandex Cloud Postbox will use these configurations as labels to separate statistics. Use the transactional configuration when sending transactional emails and the marketing configuration when sending marketing emails. On the Statistics page, select one or more configurations to view metrics only for that traffic.

You can select up to 10 configurations in the statistics filter at a time.

Breakdown by providerBreakdown by provider

In your sent email statistics, you can look up data on the main email providers (ISPs):

Provider

Domains

Yandex

yandex.ru, yandex.com, ya.ru, yandex.by, yandex.kz

Google

gmail.com, googlemail.com

Mail.Ru Group

mail.ru, bk.ru, list.ru, inbox.ru, internet.ru

Microsoft

outlook.com, hotmail.com, live.com, msn.com, windowslive.com

Other target domains fall into the Other category.

Breakdown by provider only considers the domain from the recipient's email address.
