Spam is one of the most frustrating problems with email. But there are concrete steps you can take to both clean up existing spam and prevent new spam from reaching you in the future. Here are five methods that actually work.
Method 1: Mark Spam and Train Your Filter
The simplest and most important thing you can do is consistently mark unwanted messages as spam instead of just deleting them. When you click "Mark as Junk" or "Report Spam" in Gmail, Outlook, or similar services, you train the spam filter to recognize similar messages in the future. Do this every time without exception. Over time you'll notice that more and more spam messages are automatically sorted out before they even reach your inbox. It takes 2–4 weeks of consistent marking before you see clear results.
Method 2: Unsubscribe Systematically
If you subscribe to newsletters you no longer want, unsubscribing is the right approach — not spam-marking. Under GDPR, every commercial email sent within the EU must contain an unsubscribe link, usually at the bottom of the message. Scroll down and click "Unsubscribe". Be selective though: only do this for messages from senders you recognize as legitimate businesses. For pure spam from unknown senders, unsubscribing is risky — it can confirm that your address is active and lead to even more spam.
Method 3: Create a Separate Email Address for Online Shopping
One of the most common sources of spam is online stores and registration forms. Create a dedicated email address just for shopping and subscriptions. Use it for all such registrations while keeping your primary address private for important communications. That way, if the shopping address starts drowning in spam, you can easily replace it without affecting your important communications.
Method 4: Use Temporary Email for One-Time Registrations
For websites you visit once, services you want to test, or downloads that require email verification, temporary email is the smartest solution. Instead of providing your real address, you use a disposable address that automatically expires after 10 minutes. Your real address never ends up in the website's database, never gets on mailing lists, and can never be passed on. Temp-Mail.se gives you a temporary address instantly with no registration — close the tab when you're done and the address is gone forever.
Method 5: Check if Your Address Has Been Leaked
A common cause of a sudden spike in spam is that your email address has been exposed in a data breach. Visit haveibeenpwned.com and enter your email address. The service checks against hundreds of known data breaches and shows whether your address appears in their database. If it does, you should immediately change passwords on the affected services and consider creating a new email address to break the spam flow.
