You buy something from an online shop. Three weeks later, you receive phishing emails. How did they get your address?
The Problem: Your Email Is Your Digital Fingerprint
The average person has their email address stored in over 100 databases. Every online shop, every newsletter signup, every app — they all store your email. And if just one of them gets hacked or sells your data, your address is out there.
Your email address connects everything: social media, shopping, banking. Whoever knows it, knows your digital life.
Why Spam Filters Aren't Enough
Spam filters are reactive, not preventive. They try to filter out the bad emails after they've already reached your inbox. But the data is already there — and being resold, shared, and reused.
The Alias Solution
One alias per service means: When the online shop you bought from three weeks ago gets hacked, only that one alias is affected. You disable it — and the rest of your online identity stays safe.
What You Can Do Today
- Create separate email addresses for important accounts (banking, health)
- Use aliases for all new signups
- Regularly review which services have your main address
