Cold email
Cold email is unsolicited but targeted commercial mail to a recipient with no prior relationship — legal in most jurisdictions when CAN-SPAM and GDPR rules are followed.

What it is
A cold email is a one-to-one commercial message sent to a recipient who has not previously consented to or interacted with the sender. It differs from spam in two ways: it is targeted to a specific identified individual, and it complies with the laws that govern commercial mail in the recipient's jurisdiction. It differs from marketing email in one way: the recipient is not on a list they knowingly joined.
How it works
Practitioners build a list of named prospects, enrich it with role and company data, write a short message tied to a specific reason for contact, and send through a dedicated outbound infrastructure — usually a secondary domain, warmed in advance, with strict daily sending caps. Replies and bookings come back to a human, not an automated funnel.
Legally, cold email is governed by overlapping regimes: CAN-SPAM in the United States, CASL in Canada, GDPR plus the ePrivacy Directive in the EU, and PECR in the UK. Compliance generally requires an accurate From line, an honest subject, a physical postal address in the message, and a working unsubscribe mechanism. EU and UK rules tighten further when the recipient is an individual rather than a corporate role address.
Why it matters
Cold email remains the highest-leverage outbound channel for B2B software, services, and recruiting, because it is the only one that scales while still being personal. But the channel is unforgiving: one careless campaign can blacklist a domain for months. The practitioners who survive at scale invest in three things — list hygiene, authentication, and template-based warmup — long before they press send on a single message.
