#The operating checklist
B2B email to business contact information proceeds without consent hurdles provided the purpose is genuinely business-to-business; keep identification clean, unsubscribe mechanics functional, and note that consumer-directed marketing loses the business-contact exclusion entirely. Singapore's regime is a model of why 'is cold email legal in Asia' has no single answer — jurisdictions span opt-out to strict opt-in within the same region.
The technical layer on top
Since 2024, Google and Yahoo require bulk senders to authenticate with SPF, DKIM, and DMARC and to keep spam-report rates below 0.3%. Legal compliance and inbox access are separate gates — passing PDPA (Singapore) while failing authentication or the 0.3% spam threshold still means the spam folder. The deliverability guides cover that layer.
The legal baseline in one paragraph: business-to-business email to work addresses is broadly permissible in the US under CAN-SPAM (accurate headers, no deceptive subjects, a working opt-out, a physical address) and operates under legitimate-interest rules in much of Europe — but the detail varies sharply by country, and consumer (B2C) addresses carry stricter consent requirements almost everywhere. Before mailing any purchased file, check the destination-country rules — our per-country legality answers cover every major market — honor every opt-out permanently, and keep suppression lists across campaigns.
