# Try a campaign without sending (no dry run)

> Kerux has no dry run mode: LinkedIn accounts send for real from the start. Rehearse a campaign on one contact instead.

Kerux has no dry run mode. A LinkedIn account you connect sends for real as soon as a campaign uses it, always within its limits, warm-up and working hours (see [Limits and warm-up](/help/account-safety/limits-and-warm-up.md)).

To check a campaign before it reaches real people, rehearse it on one contact.

**1. Add yourself as a contact**

Use yourself or a colleague. Add them in **Contacts** with **Add contact**.

**2. Open the test**

In the campaign's **Builder**, click **Test** in the tools row above the canvas. The **Test on one contact** window opens. A test runs the launched version, so launch the campaign first.

**3. Keep the rehearsal on**

Leave **Rehearsal: don't send anything on LinkedIn, by email or on WhatsApp** ticked. Those steps are gone through and logged, but nothing is sent. Webhooks, integrations (for example Sendspark or Slack), tags and AI steps run for real, so you can check them.

**4. Start and follow it**

Pick the contact in **Test contact** and click **Start test**. Click **Open the contact** to follow it: every step it goes through is in the contact's history.

See [Test with one contact](/help/campaigns/launch.md#test-with-one-contact) for every option.

> [!NOTE]
>
> In rare cases Kerux support puts an account in rehearsal for you. Its scheduled LinkedIn posts then say **This account is in dry run: nothing was published.**
