Labels

Labels are one of the primary elements allowing you to later define groups of subscribers by segments or send campaigns to specific labels.

Labels are easy to understand, implement (no-code), and manage.

Simply put, a label is a characteristic you can ascribe to a subscriber in your base.

There are two types of labels: user labels and system labels. The first kind can be added, modified, saved, and deleted at your convenience. The latter can only be added and modified by the system.

Another advantage of the key:value labels is that they can be used for push personalization.

A label consists of:

  • Key - the system labels have a “sys.” prefix in their key names. You can name your keys in the user labels however you want (ex. last_visit or cart_value) and use stop marks in the name

  • Value - in the form of date, number, words, or true-false value

  • Time-to-live (TTL) - a time after which the label will expire on a given subscriber

System labels contain information about a subscriber’s platform, language, region, and operating system. They are useful in defining Segments.

A label can be saved to a subscriber in one of the following ways:

  • append - simply put, it’s a set of values. For example a category label with the category-related values [blouses, jackets, scarves]. When appending, we can add a “beanie” value to the set.

  • rewrite - a relation of key and a single value. It means that we can change the value of a last_category label from last_category: beanies to last_category: blouses.

The labels are not predefined: you can ascribe them to a subscriber according to your needs.

You don't have to configure them beforehand.

Well-defined labels in automation processes or selectors help you to define more accurate segments.

You can add labels to a subscriber in the Subscribers view, during the automation scenario edition, and in the Selectors view.
