Lists Overview

You can use lists to organize your contacts into groups in order to send timely and relevant messages to your audience.

# Types of lists in Iterable

There are four types of lists in Iterable: static, dynamic, suppression, and internal.

# Static lists

A static list is a send list that consists of a set of users that doesn't change unless it's manually updated (for example, when you upload a CSV file to Iterable or when a user fills out a sign-up form).

# Dynamic lists

A dynamic list is a send list that's built with Iterable's Segmentation tool. Dynamic lists automatically find and update groups of users based on shared attributes (for example, users who have opened an email within the past 90 days).

# Suppression lists

A suppression list is a group of users who should be excluded from receiving certain campaigns (for example, you probably don't want to send a re-engagement campaign to users with a positive Brand Affinity label).

You can select suppression lists to exclude certain users from receiving blast campaigns and journeys.

# Internal lists

An internal list is a send list that consists of a group of people within your organization (it should not include any user contact info). You can use internal lists to send proofs of messages to your teammates without worrying about accidentally sending a campaign to customers before you're ready to.

List Type	Can Be Created By	Used For
Static	Uploading CSV data on the Lists page Saving the results of a search on the Segmentation page Making a call to POST /api/lists Setting up a List Membership tile in a journey	Sending campaigns to users
Dynamic	Saving the results of a search on the Segmentation page	Sending campaigns to users
Suppression	Uploading CSV data on the Lists page	Preventing users from receiving campaigns
Internal	Uploading CSV data on the Lists page	Testing campaigns prior to sending

# Viewing your project's lists

The Lists page is where you can view and manage your existing lists, import new lists, export a list of unsubscribed users by channel, add or remove subscribers from a channel, and delete lists.

To view your project's lists, go to Audience > Lists.

# Viewing the current size of a dynamic list

The number of users in a dynamic list fluctuates over time as new users are added and/or existing users are removed. On the Lists page, the total number of users in a dynamic list (shown in the Contacts column) is updated once per hour — so the number being displayed on the Lists page may not be the most current number. To see the most up-to-date size of a dynamic list, you can open the list or refresh the Lists page after an hour.

Dynamic lists always include all the users who match the defining segmentation query, even if the list size hasn't been updated on the Lists page yet. When you send a campaign to a dynamic list, the campaign is sent to all the users who match that list's segmentation criteria at send time.
