# Blocklists

Block form spam with Form Plume blocklists: filter by keyword, email domain, IP address, and CIDR network range, all scoped to your account.

Some abuse is specific to your form. Blocklists let you stop the patterns you already know about.

## Keywords

Add phrases that clearly identify unwanted submissions. Prefer a specific phrase over a broad word that legitimate customers may use.

## Email domains

Enter the domain without a protocol or path:

```text
example-spam.com
```

Use [Email hygiene](/docs/spam-protection/email-hygiene) for disposable providers and domains without mail servers.

## IP addresses and networks

Block one address or a CIDR range. Be careful with large ranges because offices, mobile carriers, and shared networks can place many people behind the same addresses.

Every blocklist belongs to your account. A value blocked by another Form Plume customer does not automatically affect your forms.
