How to avoid spam with throwaway mail

Spam filters help, but they cannot unsell your address once it lands on a list. Prevention beats filtering.

Why spam sticks around

Marketing databases merge, resell, and resurrect old contacts. An address you typed into a quiz in 2019 can still receive pitches in 2026.

Using a dedicated disposable address for risky signups means the blast never reaches the inbox you check every morning.

A simple workflow

1. Open voidmail and copy your temporary address.
2. Paste it into the signup form.
3. Confirm the verification email in your voidmail inbox.
4. When you are finished, generate a new address — the old one stops being yours.

When to keep your real email

Use your primary address only when you need long-term access: billing receipts, account recovery, or people who must reach you months later.

For everything else, a throwaway inbox is the spam firewall you control.
