## Rate Limiting & Throttling

### Default Rate Limits

By default, Postmark providers are configured with a rate limit (e.g. **Max Sends Per Hour**). This limit is set at the provider level and applies to all emails sent through your Postmark integration.

### Configuring Rate Limits

You can adjust the rate limit in the SendPost UI:

<Steps>
  <Step title="Navigate to Providers">
    Go to **Settings** → **Providers** in your SendPost dashboard
  </Step>

  <Step title="Edit Provider">
    Click on your Postmark provider to edit its settings
  </Step>

  <Step title="Adjust Rate Limit">
    Update the **Max Sends Per Hour** value to match your Postmark plan or desired sending rate
  </Step>

  <Step title="Save Changes">
    Save your changes. The new rate limit takes effect immediately.
  </Step>
</Steps>

<Info>
  Rate limiting in SendPost is configured on an hourly basis. Set it according to your Postmark plan capacity and sending requirements.
</Info>

### Provider-Level Throttling

SendPost supports granular throttling by recipient domain:

| Provider | Description                             |
| -------- | --------------------------------------- |
| Gmail    | Throttle sending to Gmail addresses     |
| Yahoo    | Throttle sending to Yahoo/AOL addresses |
| Outlook  | Throttle sending to Microsoft addresses |
| Default  | Throttle for all other domains          |
