# Nudge Non-Responders

Most people who see a survey never answer it. **Nudge Non-Responders** automatically sends a single, gentle reminder to anyone who was sent or presented a survey but didn't respond — so you recover responses you would otherwise have lost, without any manual follow-up.

The reminder is **one-time** and **self-cancelling**: if the person responds before the reminder goes out (or at any point before it's sent), it is skipped automatically. Nobody who has already answered will ever receive a nudge.

{% hint style="info" %}
This setting is configured per survey. Turn it on for each survey you want to nudge.
{% endhint %}

### Enabling it

1. Open your survey and go to the **Delivery Settings** tab.
2. Find the **Nudge Non-Responders** card and toggle it on.
3. Set how long to wait before the reminder is sent — for example, **3 days** after the survey is sent if there's still no response. You can choose **hours** or **days** as the unit.
4. (Optional) Customize the reminder subject (email) or reminder message (SMS) — see [Customizing the reminder](#customizing-the-reminder) below.
5. Save your survey.

That's it. Eligible non-responders are followed up automatically on the schedule you set.

### How the reminder is delivered

The reminder is sent over the **same channel the survey was delivered on**:

* **Email surveys** (email campaigns, CSV email, Shopify customer-segment email) → a reminder **email**.
* **SMS surveys** (SMS campaigns, CSV SMS, Shopify customer-segment SMS) → a reminder **text message**.
* **Shopify post-purchase / on-site surveys** → a reminder **email**, sent when a customer email is known for the order (for example, the email captured at checkout). Post-purchase reminders are scoped per order, so a returning customer who skips a later survey is still followed up for that new order.

A reminder can only be sent when Zigpoll has a way to reach the person (an email address or phone number). Anonymous surveys have no recipient, so the Nudge Non-Responders card is hidden for anonymous surveys.

### Customizing the reminder

By default the reminder reuses the original survey's subject line (email) or message (SMS). You can override this from the Nudge Non-Responders card:

* **Reminder subject** *(email surveys)* — a different subject line for the follow-up email, e.g. *"Quick reminder: we'd still love your feedback"*.
* **Reminder message** *(SMS surveys)* — a different text for the follow-up message.

Leave either field blank to resend the original subject or message.

### When a reminder is skipped

A nudge is **not** sent if:

* The person responds before the reminder is due (the reminder is cancelled the moment a response is recorded).
* The survey is anonymous.
* There is no email address or phone number to reach the person.

### Tracking nudges

Sent reminders are visible in two places:

* **Activity feed** — filter by **Nudge** to see every reminder that was sent.
* **Participant timeline** — a *"Sent a nudge to: …"* entry appears on the participant's history, followed by their response if they came back and answered.

{% hint style="info" %}
Nudge reminders count toward your account's email and SMS sending limits, just like the original survey send. See [Subscription Plans](/subscription-plans.md) for limit details.
{% endhint %}
