Constraints are the specific values of properties used to search for people and create segments. Constraints vary depending on the type of filter you select. Here are the options you will see for the following field types:


The field contains letters and numbers describing the value. Examples include name fields, email address, and country. The following operators apply to string fields:

  • Contains: The user's field has the value in at least part of the field.
  • Does Not Contain: The user's field does not contain the value in any part of the field.
  • Exists: The user has a value in this field. Useful for finding users who have fields that are only generated in certain ways such as email clicks or landing pages.
  • Does Not Exist: The field does not exist for the user.
  • Starts With: The user's field starts with the value.
  • Does Not Start With: Opposite of Starts With.
  • Ends With: The user's field ends with the value.
  • Does Not End With: Opposite of Ends With.
  • Is Not: The user's field is not exactly equal to the value.
  • Regexp: Create a regular expression to compare against the user's field.


List fields are made up of limited choices that the user could select from such as terms and applications. When filtering these fields, you are giving the same list of options to choose as values. Multiple conditions may be added to list field filters. The following conditions apply to list fields:

  • Is: The value matches the user's field.
  • Is Not: The value does not match the user's field.
  • In: The user's field matches any of a number of choices in the value. You are able to select more than one choice using "In"
  • Not In: The user's field does not match any of the values chosen.


Date fields contain data on when a user completed an action such as submitting an application or survey or their birth date. The following operators apply to date fields:

  • When: Relative/Exact.Relative: Relative dates are measured from a certain point and are built in the form of "From 5 to 7 days ago" where you fill in the following fields:From: Number of days/weeks/months/years.To: Number of days/weeks/months/years....Ago: Select days/weeks/months/year.Exact: Choose an exact range of dates between a start and end date.


Geo fields allow you to filter by the distance from a given point. The following operators are used for geo fields:

  • Address: The address from which to measure. Beginning to type here will bring up an auto-complete using Google maps to assist you finding the exact address.
  • Value: The number of miles/kilometers you would like to set as a maximum distance from the chosen address.
  • Unit: Choose to measure in miles or kilometers.

Now that you're familiar with constraints, put them to use by learning how to create a segment.
