Add-ons are **optional extras** you can layer onto your base hosting plan. Each is billed separately and can be enabled or removed from your client portal at any time.

<Aside type="note">
  An add-on is billed in addition to your base plan. Removing an add-on stops the charge from the next billing cycle.

## What's available

- **[Site Monitoring](/whp/add-ons/monitoring/)** — proactive alerts when something looks wrong (error spikes, brute-force attempts, exploit signatures).
- **[Archival email](/whp/add-ons/archival-email/)** — long-term, searchable retention of your mail outside the live mailbox.
- **[Resource upgrades](/whp/add-ons/resource-upgrades/)** — extra CPU, RAM, or storage without changing plans.
- **[Email upgrades](/whp/add-ons/email-upgrades/)** — extra mailboxes or larger per-mailbox storage caps.
- **[Optimized Webserver](/whp/add-ons/optimized-webserver/)** — run your sites on OpenLiteSpeed with server-level LSCache for dramatically faster page delivery.

## How billing works

Add-ons are **pro-rated** to align with your base plan's billing cycle and appear as separate line items on your next invoice. Cancelling an add-on stops it from the next cycle — you keep access through the end of the period you've already paid for.

## How to enable an add-on

1. Sign in to the [client portal](https://secure.anhonesthost.com/clientarea.php).
2. Go to **Services → My Services** and pick your hosting plan.
3. Click **Upgrade/Downgrade** (sometimes called **Add-ons** depending on the add-on).
4. Pick the add-on, review the price, and confirm.

WHP applies the change usually within a few minutes — no downtime for any of the add-ons listed here.
