SingaporeIs spam email illegal in Singapore?
Yes, sending unsolicited commercial emails (spam) is illegal in Singapore under the Personal Data Protection Act 2012, which prohibits such messages without consent and requires clear unsubscribe mechanisms.
What the Law Says
The Personal Data Protection Act 2012 (PDPA) makes it illegal to send unsolicited commercial electronic messages — including spam email — unless strict conditions are met.
Section 43 of the PDPA specifically prohibits the sending of marketing messages via email (or other electronic means) to individuals without their prior consent. This applies to all organisations operating in Singapore, including foreign companies targeting Singapore residents.
Even with consent, every commercial email must include a clear, functional, and free unsubscribe mechanism. The sender must honour opt-out requests within 10 business days.
Violations can lead to enforcement action by the Personal Data Protection Commission (PDPC), including financial penalties and public censure.
Statutory TextNo person shall send or cause to be sent to any individual any marketing message by electronic means unless the individual has given his consent to the sending of the message and the message contains a statement informing the individual of his right to request the sender to stop sending him marketing messages.
