When you merge multiple contact lists together, you can choose to move all the contacts from your selected lists into a new or existing list. You can create a new list at the same time you perform the merger, but if you want to create your new list ahead of time, that's fine too! Once you merge contact lists together, it can't be undone.


After your lists are merged, the original lists are left as-is, but you can always rename or delete them later. Sometimes a single contact can be part of multiple lists. If one contact is on multiple lists being merged together, the contact only appears once in your resulting list. If the same contact is on other lists that weren't merged, they remain on those lists. You can view a contact's record to see all the lists they belong to.
| Did you know? You can use our segmentation tools across multiple lists to find your most or least engaged contacts, or find contacts based on the contact details you have on file for them. |
