Frequently asked questions
+ Is spam the same as phishing?
No. Spam is unwanted, mass-distributed messages — often intrusive advertising, but not necessarily dangerous. Phishing is deliberate fraud that impersonates a trusted institution in order to extort data or money. Phishing is sometimes distributed as spam, but classifying a message as spam does not in itself mean an attack — the key difference is intent: nuisance (spam) versus extortion (phishing).
+ What is phone spam (SMS and calls)?
Phone spam is unwanted SMS messages and calls: advertisements, fake parcel notifications, loan offers, and also smishing (SMS with links that phish for data). On a phone, it is reduced by blocking numbers, the spam filters built into the system (iOS/Android), anti-spam apps and reporting numbers to the operator and the national CERT.
+ How can you effectively reduce the amount of spam?
The most effective methods are: not publishing your email address and phone number in public places, using anti-spam filters (on the server and mail-client side), not clicking 'unsubscribe' links in suspicious messages, using disposable addresses for registrations and, in companies, mail gateways and Secure Email Gateway-class solutions that filter spam and phishing before they reach mailboxes.
+ Is sending spam legal?
In the European Union, unsolicited marketing communication is generally illegal without the recipient's consent — this is governed by the GDPR and by regulations on the provision of electronic services and telecommunications law. Mass spam containing phishing or malware is already a crime. Legal email marketing requires prior consent (opt-in) and an easy way to opt out.
