Report as Spam and Use Email Filters
The most effective immediate response to subscription bombing is to let your email provider's spam filters learn and block the unwanted messages.
When an automated service targets your email address, you may receive thousands of messages in a short time. Many of these subscriptions remain inactive until verified.
By simply ignoring the verification requests and marking them as spam, you prevent the subscriptions from activating and help your email provider improve its filtering.
Leave unverified subscriptions alone. Do not click any links that say 'Confirm your subscription' or 'Unsubscribe', as this confirms your account is active.
Select the unwanted emails in your inbox and click your email provider's 'Report Spam' or 'Junk' button to train the filter.
Access your email settings and create custom filters to automatically move emails containing words like 'subscription' or 'verify' from unknown senders directly to the trash folder.

Secure Your Email Account Settings
Ensure your email account hasn't been compromised by unauthorized users by updating your security and recovery settings.

Frequently Asked Questions
Why is someone signing my email up for hundreds of newsletters?
This tactic is known as 'subscription bombing' or 'email bombing.' Malicious actors use automated scripts to flood your inbox with harmless newsletters to hide important security alerts, such as unauthorized bank transactions or account password resets.
Should I click 'unsubscribe' on these unwanted emails?
No. Clicking 'unsubscribe' on unverified or suspicious emails confirms to spammers that your email address is active and monitored, which can lead to even more spam in the future. It is better to mark them as spam.
Will these unwanted subscriptions charge my credit card?
No, signing up for free newsletters and web forums requires only an email address. However, you should check your financial accounts directly to ensure the spam flood isn't masking a real fraudulent transaction alert.
How long does a subscription bombing attack usually last?
Most automated subscription bombing attacks are temporary and will stop after a few hours or once a few thousand emails have been sent. Continuing to mark them as spam will mitigate the annoyance until it ends.
