# Duplicate Campaign

> Creates a copy of an existing campaign including sequences, settings, and optionally sub-sequences and client labels.

<Note>
  Duplicates an existing campaign with all its configuration — sequences, variants, settings, schedule, email accounts, and LinkedIn cookies. Leads are **not** copied.
</Note>

## Overview

Creates a full copy of a campaign, preserving its sequences (with variants), schedule, settings, email account mappings, and LinkedIn cookie mappings. Useful for replicating a proven campaign setup without manually recreating it.

**What Gets Duplicated:**

* Campaign settings (tracking, sending limits, stop conditions, AI categorisation, etc.)
* All email sequences with variants and A/B test settings
* Schedule and timezone configuration
* Email account associations
* LinkedIn cookie mappings
* Optionally: sub-sequences and client label

**What Does Not Get Duplicated:**

* Leads — the new campaign starts empty
* Campaign analytics and statistics
* Webhook configurations
