Email Bombing & How to Defend Against It

An email bomb is a sudden flood of subscription-confirmation and junk emails aimed at one address. It's often a smokescreen.

Why attackers do it

The flood buries a real notification — like a "your card was charged" or "password changed" alert — so you miss a fraud in progress.

How they do it

Attackers script sign-ups to thousands of newsletters using your address, triggering a confirmation avalanche.

Defenses

• If you're suddenly flooded, immediately check financial and key accounts for unauthorized activity.
• Use provider-side filtering and rules to quarantine the surge.
• Keep low-trust sign-ups on disposable addresses so your primary inbox is a smaller target.
