Emailing and calling businesses in Singapore

Can I email businesses from a list in Singapore?

The Spam Control Act sets requirements for unsolicited commercial email sent in bulk, such as an unsubscribe facility, an <ADV> label and honest headers. It does not set a prior-consent rule. The PDPC says the DNC Provisions cover calls, texts and faxes to Singapore numbers, but they do not apply to B2B marketing messages sent to business telephone numbers.

Main rules: Spam Control Act 2007 and the Do Not Call (DNC) Provisions of the Personal Data Protection Act (PDPA). A summary of the official guidance linked below, checked 2026-11-11; not legal advice.

Email

  • Section 6 counts messages as sent in bulk above 100 similar messages in 24 hours, 1,000 in 30 days or 10,000 in a year. Section 11 then applies the Second Schedule.
  • Include an email address for unsubscribe requests, with a clear statement in English. The address must work for at least 30 days.
  • Stop sending within 10 business days of an unsubscribe request.
  • Put '<ADV>' before the subject line, keep the subject and header honest, and give an accurate email address or phone number for contact.

Phone calls

  • The PDPC says the DNC Provisions do not apply to B2B marketing messages sent to an organisation's contact details, such as an office landline.
  • They do apply if the message also markets goods or services for the recipient's personal use. Then you must check the DNC Registry within 21 days before sending, unless you have clear consent.
