Open Doors prevents most duplicates automatically by matching on email and phone at create time. Duplicates usually come from imports that lacked one of those fields.

Manual merge

  1. 1
    Open the keeper contact
    The one that will survive after the merge.
  2. 2
    Click ⋮ → Merge duplicates
    Open Doors suggests candidates based on similar name and matching email or phone.
  3. 3
    Review differences
    Pick which value wins for each field where they disagree.
  4. 4
    Confirm
    Timelines, tags, opportunities, and conversations merge into the keeper.

Bulk dedupe

Contacts → ⋮ → Find duplicates runs the matching across your whole database. Review each suggested pair and accept or skip.
