Spam Protection

Spam protection uses blacklists, heuristics, and rate-limits to block malicious destinations and abusive behavior, keeping your brand and users safe.

---

Key mechanisms

• Domain and URL blacklist/allowlist checks.
• Heuristics for suspicious patterns and velocity.
• Bot detection & challenge for automated attacks.

With Cuttly in practice

Cuttly vets custom domains and monitors abuse patterns. Suspicious links can be disabled, and bot clicks are counted separately in Analytics.
