Rules depend on country, audience, and channel

There is no single global cold-outreach law. Your obligations shift with where the recipient is, whether they're a business or a consumer, and whether you're emailing, calling, or messaging. Before you scale, know which rules apply to the markets and channels you actually use - assumptions are how campaigns get flagged.

  • Recipient's country and its anti-spam law.
  • Business vs consumer contact.
  • Channel: email, phone, or messaging.
  • Any sector-specific rules.

The safeguards that travel across most regimes

A handful of practices keep you defensible almost everywhere: a truthful sender identity, a clear reason for contact, an easy opt-out, honoring opt-outs promptly, and a suppression list so you never re-contact someone who declined. Build these in from the first send, not after a complaint.

  • Truthful sender details and subject.
  • A visible, working opt-out.
  • Prompt suppression of opt-outs.
  • No deceptive or harvested data.

Public availability is not blanket permission

A published business email or phone can be used for a genuine, relevant business reason - but that's not the same as consent to market anything to anyone. Keep contact relevant to the recipient's public business context, and treat individuals and consumers with more caution than clearly business contacts.

When in doubt, get advice - this isn't it

This is general guidance, not a substitute for professional advice. Rules like GDPR, PECR, CAN-SPAM, CASL, and local calling regulations carry real penalties and specific requirements. For anything beyond small, careful, business-to-business outreach, confirm your approach with a qualified professional for your markets.
