## Built-in templates

These templates are ready to use and marked **Built-in**:

- DMCA Takedown Notice and DMCA Follow-Up (category Legal)
- ARC Request and ARC Application Declined (category ARC)
- Beta Reader Application Declined

You can't change a built-in template directly. To customize one:

1. Find it in **Email Templates**.
2. Click **Duplicate**.
3. Edit the copy and click **Save Changes**.

## The ARC Delivery template

The first time you use **File Watermarker**, an editable template called **ARC Delivery (Default)** is added to the ARC category. It has a **Watermarker Default** badge. File Watermarker uses it as the starting email when you send a copy, so editing it changes that default message.

## Categories

To add, rename or delete categories:

1. Click **Manage categories**.
2. Type a name and click **Add** to make a new category. You can add one before any template uses it.
3. Rename or delete a category from the list.

The Legal and ARC categories are built in and can't be renamed or deleted. If you delete one of your own categories, its templates move to Custom.

## Other tips

- Each card shows how many times you've used the template, for example Used 3×.
- Click a card to preview it.
- If you delete a template by mistake, click undo in the message that appears.
