# Email verification, from key to decision

Bounceless gives applications and agents an explainable verification result and a Pre-Send decision. Start with a Bounceless account, create an API key, then choose the interface that fits your workflow.

<Steps>
  <Step title="Create an account">
    [Sign up for Bounceless](https://app.bounceless.io/signup), then open the dashboard.
  </Step>

  <Step title="Create an API key">
    Open [API keys](https://app.bounceless.io/settings/api-keys). Copy the new key when it appears; it is shown once.
  </Step>

  <Step title="Run a controlled check">
    Follow the [quickstart](/quickstart) with a synthetic or otherwise authorized address. Keep the key out of source control, prompts, and screenshots.
  </Step>
</Steps>

Email verification reduces uncertainty; it does not guarantee inbox placement or sender-reputation outcomes.
