Permission and opt-out rules for B2B cold email by country
Rules for B2B cold email differ by country. See three official quotes (Canada, US, UK) and the questions to ask counsel for every other market.
Short answer: rules for B2B cold email differ by country, and business email is not exempt everywhere. This guide quotes three official pages, from Canada, the United States and the United Kingdom, and lists the questions to ask counsel for every other country you contact. It is not legal advice.
Vivin Sales charges USD $15 to $500 per accepted lead. Each lead is exclusive and never resold, a lead that is off-criteria is replaced, and there is no setup fee. Every fee is listed in your written quote before you sign.
Do the same permission rules apply in every country?
No. Each country sets its own rules on who you may email, what permission you need and how people opt out, so ask counsel instead of assuming that a message allowed in one country is allowed in another. Do not assume a business address is outside the rules.
If a provider sends email for you, ask which rules it follows in each country it contacts. Then ask how it records permission and opt-outs, because you need that record if a recipient complains. Our guide to comparing B2B lead generation agencies fairly puts compliance in its comparison table.
What does Canada’s anti-spam law say?
Canada’s anti-spam law is known as CASL. Section 6(1), on the Justice Laws statute page, read on October 23, 2026, includes this condition for sending a commercial electronic message: “has consented to receiving it, whether the consent is express or implied”. That phrase is one condition among others in the section, so it is a starting point for your counsel, not a complete statement of the law.
The practical question for a buyer is how permission is established and recorded for each recipient, and which kind your provider relies on. Ask to see the record for a sample contact.
What does the United States say about business email?
The US Federal Trade Commission states in its CAN-SPAM compliance guide, read on October 23, 2026: “The law makes no exception for business-to-business email.” The guide is the regulator’s own summary, so ask counsel how it applies to your messages, your lists and any calling or texting that goes with them.
What does the United Kingdom say?
The UK Information Commissioner’s Office publishes guidance on electronic mail marketing. On its electronic mail marketing page, read on October 23, 2026, it states: “You can email or text any corporate body (a company, Scottish partnership, limited liability partnership or government body).” The same page also raises possible data protection implications when emailing employees at those bodies, so read the full page and ask counsel before you rely on one sentence.
We did not fetch an official page for any other country, so this guide states no rule for them. Rules differ by country, and the European Union, Australia and other markets each need their own advice.
Which questions should you ask counsel for each country?
Use the same list for every country you plan to contact.
| Question | Why it matters |
|---|---|
| Which law covers commercial email to businesses? | The answer names the rule your messages must follow |
| Is permission needed before the first message? | It decides whether a cold message can be sent at all |
| What counts as valid permission? | It sets the evidence you must keep |
| What must each message contain? | Ask for the required contents in writing |
| How must opt-outs work, and by when? | You need a process and a deadline written down |
| Do rules differ for named individuals? | Ask whether personal data rules also apply |
| Which regulator and penalties apply? | It tells you the cost of getting it wrong in that market |
Counsel can answer these for the country and the facts of your campaign. Write the answers into the agreement with your provider.
What should the agreement say about permission and opt-outs?
Ask for written statements on three points: which countries the provider contacts for you, how permission is recorded and how opt-outs are handled and shared. Vivin’s lead agreement says campaigns run under CASL in Canada and CAN-SPAM in the United States, and names the other laws that apply for each country. It also says suppression lists are loaded before launch and opt-outs and consent withdrawals are honoured with no end date. The compliance page explains the approach. That is a description of Vivin’s practice, not advice for yours.
Also ask who holds the suppression list at the end of the work, so an opt-out does not disappear when you change provider. For the sources behind a contact, see red flags that a B2B lead vendor sells scraped lists, and for a sector view, read pay per lead for financial advisors. The pay per lead company comparison lists what other providers publish about themselves, and the lead generation hub shows how the models differ.
Frequently asked questions
Is B2B cold email exempt from permission rules?
Not everywhere. The US Federal Trade Commission says its law makes no exception for business-to-business email, and Canada’s statute speaks of consent. Ask counsel about each country.
Can I use one opt-out process for every country?
That is a question for counsel. Deadlines and wording can differ by country, so ask for the rule in each market and write the process you need into the agreement.
Who is responsible if my provider sends the email?
Allocate responsibility in the contract and ask counsel to review it. Ask the provider to state the rules it follows and how it records permission.
Where can I read the rules Vivin says it follows?
In the compliance and data section of the lead agreement. Ask for the countries covered in your written scope, and take advice on any country the agreement does not name.
