Cold outreach compliance beyond Europe, in plain terms
The short answer
Different regions have different cold email laws: the EU has GDPR, the US has CAN-SPAM, Canada has CASL, and others vary. The details differ, but the safe habits are the same everywhere: identify yourself honestly, target a genuine business reason, make opting out easy, and honour it. Follow the strictest rule that applies and you are broadly safe across markets.
Outbound rarely stops at a border, and the rules do not either. You do not need to be a lawyer, but sending across markets means knowing that the compliance bar moves, and that a few universal habits keep you on the right side of most of it.

There is no single global rule
Cold email is governed regionally, and the regimes differ in both letter and spirit. What is routine in one market can be a violation in another, so where your recipient is matters as much as where you are.
The practical response is not to memorise every statute, but to understand the shape of the main ones and adopt habits that satisfy the strictest.
The EU: GDPR and consent-or-interest
In Europe, GDPR governs, and B2B cold outreach generally rests on legitimate interest: contacting someone about their professional role, with identification and an easy opt-out. The full picture for Europe is in the GDPR guide; the key point here is that it is one of the stricter regimes.
The US: CAN-SPAM
The US takes a lighter, opt-out approach under CAN-SPAM. Broadly: do not use deceptive headers or subject lines, identify the message honestly, include a valid physical postal address, and provide a working way to opt out that you honour promptly.
It is more permissive than GDPR, but the honesty and opt-out requirements are real and enforced.
Canada: CASL
Canada's CASL is among the strictest, leaning toward requiring consent, with some business-relationship exceptions, and carrying significant penalties. If you send into Canada, treat it as a high-bar market and understand the specifics rather than assuming a US-style opt-out approach is enough.
The habits that travel
You can satisfy most regimes at once with a few consistent practices.
- Identify yourself and your company honestly, no deceptive headers or subjects.
- Have a genuine, business-related reason to contact this person.
- Include a real, easy way to opt out, and honour it immediately and permanently.
- Where required, include a physical postal address.
When in doubt, follow the strictest
The simplest safe policy for cross-border outbound is to hold yourself to the strictest standard that could apply to any recipient, usually the European or Canadian bar. Do that and you are compliant almost everywhere by default.
This is general guidance, not legal advice. For significant or high-volume cross-border sending, confirm the specifics for your markets. But honest identification and a respected opt-out will keep most senders on the right side of most laws.
