Lists vs. Segments

Lists:

• Fixed sets of contacts stored in a database.
• Each user belongs to a specific list.
• If the same contact is in multiple lists, it counts as a duplicate.
• Typically used for distinct subscriber groups (for example, VIP Clients, Leads, Former Clients).

Segments:

• Dynamic groups within a list, created based on specific filters and criteria.
• Contacts are automatically added or removed as they meet (or no longer meet) the defined criteria.
• Useful for personalized campaigns, such as targeting users based on interaction (for example, those who opened an email in the last 30 days).

Practical Example:

List: All subscribers to your newsletter.

Segment: Only subscribers who opened the last email.
