# Nudges

> Re-engage customers with reminder WhatsApp messages

## What are Nudges?

Nudges are **WhatsApp reminder messages** sent to customers who visited your store through a referral link but haven't received a message recently. They help re-engage dormant referrers and encourage them to share again or complete a purchase.

## Prerequisites

Before sending nudges, ensure you have:

1. An **active campaign** — nudges require a running campaign.
2. A **WhatsApp provider** configured in [WhatsApp Settings](/docs/features/whatsapp/overview).
3. The **Nudge Reminder Template** configured and enabled in [WhatsApp Settings](/docs/features/whatsapp/touchpoints).

## How to Send Nudges

1. Go to **Apps → Referbro → Nudge Users**.
2. Set **Days since last message** — only users who haven't received a WhatsApp message in this many days will be targeted.
   * Default: `7` days
   * Valid range: `1` to `365` days
3. Click **Send Nudge Messages**.

## Who Gets Nudged?

The system automatically identifies users who:

* Have visited your store through a referral link
* Haven't received a WhatsApp message in the specified number of days
* Have a valid phone number for messaging

## Results

After sending, you'll see a summary:

* **Successful nudges** — Messages sent successfully
* **Total eligible users** — Users who met the criteria
* **Errors** — Any failures (up to 5 shown, with a count of remaining)

<Note>
  Nudge messages are sent to all eligible users at once. Use the "days since last message" parameter to control how frequently users are re-engaged.
