# Opt-in and acquisition

> Capture subscribers with an opt-in popup and measure conversion.

The opt-in popup captures leads in exchange for an incentive (welcome
points or a discount) and adds them to your loyalty program with their consent.

## How it works

<Steps>
  <Step title="The visitor sees the popup">
    A popup is shown with an image and an offer (points or discount) in exchange
    for their email.
  </Step>

  <Step title="They sign up with consent">
    The customer leaves their email and agrees to receive communications. The opt-in is saved.
  </Step>

  <Step title="They receive the incentive">
    The welcome points or promised discount are granted.
  </Step>
</Steps>

## Metrics

<CardGroup cols={2}>
  <Card title="Conversion rate" icon="chart-line">
    Sign-ups over visits, with a 7-day moving average to smooth out daily noise.
  </Card>

  <Card title="Strategy sign-ups" icon="user-plus">
    Only sign-ups generated **while the opt-in strategy is active** are
    counted. Days with the program off don't add up.
  </Card>
</CardGroup>

<Note>
  **Imported** sign-ups (migration of existing customers) are not counted
  as a popup conversion, so as not to inflate the metric.
</Note>

## Independent toggle

The opt-in strategy has its own switch, independent of the overall program
state. By default it starts **off**: turning it on enables both the
functionality and its measurement.
