When you merge multiple contact lists together, you can choose to move all contacts from your selected lists into a new or existing list. You can create your new list ahead of time or during the merge. Once you merge contact lists together, it can't be undone.


After your lists are merged, the original lists remain as-is, and you can always rename or delete them later. Sometimes a single contact can be on multiple lists. If a contact is on multiple lists being merged, the contact appears only 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. |
