What laws apply to B2B cold email (EU, UK, US, Canada, Brazil)?

B2B cold email rules vary significantly by jurisdiction:

United States: CAN-SPAM applies equally to B2B and B2C. No consent required, but compliance requirements apply (identification, opt-out, physical address).

European Union: GDPR applies to personal data processing. The ePrivacy Directive allows member states to permit unsolicited B2B marketing. Implementation varies: Germany is strict; UK (when in EU) was more permissive.

United Kingdom: PECR distinguishes between corporate subscribers (unsolicited B2B permitted) and individual subscribers (consent required). Sending to info@company.com differs from jane.smith@company.com.

Canada: CASL applies to all commercial electronic messages. B2B doesn't get special treatment. Limited implied consent for conspicuous business addresses where the message relates to their role.

Brazil: LGPD (Lei Geral de Proteção de Dados) requires legitimate basis for data processing. Consent or legitimate interest may apply, similar to GDPR structure.
