Classic list picker deprecation
The classic list picker, and the ability to send campaigns to multiple lists, is currently available to accounts created before April 2020. From 4th August 2025 this will no longer be available in any accounts.
We've made this decision to improve the contact management, compliance and deliverability. Sending to multiple lists can cause contacts to receive more than one copy of your email and make it hard to properly manage unsubscribes, which can impact your sender reputation and ours.
Duplicating a campaign will still be available, but for the best user and subscriber experience, we recommend combining your lists before this date. Read this guide to learn how to merge your lists: How to merge multiple lists into one.
We’ve recently introduced some new features to help you manage your contacts. Using tags, custom choice fields, subscriber profiles, and segments can help you better organise your contacts in a single list. It can also help you make savings on your bill, as you wouldn’t pay for duplicate contacts across multiple lists.
