Does CAN-SPAM apply to a one-to-one B2B introduction email?
CAN-SPAM can apply to business-to-business email, because it regulates commercial messages and is generally understood not to exempt business recipients. A permissioned one-to-one introduction is lower risk than a bulk send, but the message should still be honest, identify the sender, include an address and offer an opt-out.
Short answer: does CAN-SPAM reach B2B email?
It can. The CAN-SPAM Act regulates commercial electronic mail, and it is generally understood to cover business recipients as well as consumers. Whether a particular introduction counts as "commercial" depends on its primary purpose, which is a fact question about the message, not a label you choose.
Read the FTC's CAN-SPAM compliance guide and the statute itself before relying on this page; treat the summary below as a list of questions to check, not a ruling. This is general information, not legal, tax or financial advice. Confirm with your own counsel before acting.
Why does a permissioned one-to-one introduction lower the risk?
The program is built around single, owner-approved introductions, not bulk sends. A partner introduces a company that has agreed to be contacted, usually in an email the owner has seen or requested. That pattern differs from the cold, list-driven messages the law was written to curb in three ways.
- Consent exists before the message. The owner agreed to the introduction.
- Volume is one. One message to one person is not a campaign.
- The purpose is mutual. The owner asked to hear about the program.
None of this makes a message exempt. A one-to-one email that promotes a commercial product or service can still be a commercial message, so the basics below apply as good practice either way.
The basics a commercial email should meet
These are the commonly cited requirements for commercial email. Confirm each against the FTC guide and the statute, because they are summarized here from general knowledge.
| Requirement | Plain-language meaning | Practical step |
|---|---|---|
| Accurate header information | From, To and routing details are not misleading | Send from your real address, under your real name |
| Honest subject line | The subject reflects the message | "Introduction: {first_name} and SourceX" |
| Identify as an advertisement where required | Do not disguise a commercial message | Say plainly why you are writing |
| Physical postal address | The sender's valid address is included | Put it in your signature |
| Opt-out mechanism | The recipient can say stop, easily | A line such as "Reply stop and I will not write again" |
| Honor opt-outs promptly | Do not email after a stop request | Keep a do-not-contact note |
| Responsibility for others | Both the company whose product is promoted and the sender may be responsible | Do not outsource sending to someone you cannot supervise |
What does this mean in common partner situations?
| Situation | What to check | Likely approach to confirm |
|---|---|---|
| You email an owner you know, with their agreement | Is the message about the introduction or a promotion? | Keep it brief, honest and opt-out-friendly |
| You email an owner you do not know, with no prior agreement | Is it a commercial message? Do you have permission? | Avoid; seek a warm route first |
| You send the same text to many owners | Is it bulk commercial email? | Do not; this is not how the program works |
| You use a tool that sends sequences | Who is the sender, and who honors opt-outs? | Do not use sequences for this program |
| You reply to a person who asked about the program | Is the reply a transactional or relationship message? | Answer the question and keep it factual |
Programs like this one are not for lead-list sellers or cold-outreach affiliates. See how SourceX referrals work for the permission-first model.
Disclose that you may be paid
Separate from CAN-SPAM, the FTC's Endorsement Guides address connections between a person who recommends something and the business that benefits. The agency's 16 CFR Part 255 and its FAQ on endorsements explain that a connection a reader would not expect should be disclosed. A referral reward is such a connection, so say so in the email in one plain sentence. Do not type the reward amount. Rewards are 25% of the eligible platform fees SourceX actually collects, capped at $100,000 cumulative per referred company, and they become payable only after the buyer pays and SourceX receives its fee. No reward is guaranteed.
A safe structure for the email
The company introduction email template and the introduction email builder give wording. Use this order.
- A subject line that says what the email is.
- One sentence on who you are to the owner and that they agreed to the introduction.
- One sentence on what SourceX does: licensing company records to AI developers, with the company keeping ownership.
- One sentence disclosing that you may receive a reward if a deal completes.
- A clear way to stop receiving messages.
- Your name and postal address.
For who replies first and when to move to BCC, see the introduction etiquette guide.
Other rules can apply
CAN-SPAM is a US federal law. If you or the recipient are elsewhere, other rules can apply, and licensed professionals have their own conduct rules on fees and communications. If your introduction crosses a border, see introducer agreements. If you also refer to other programs, see referring the same company to more than one program. Ask your counsel about referral fee clawbacks in the same conversation.
Questions for your counsel
- Is my introduction email a commercial message under the statute?
- What should my signature, subject line and opt-out wording say?
- Do my other rules, such as my profession's, require extra disclosure?
- If I use a tool, who is the sender in law?
Next step
Draft one owner-approved email, keep it plain, and register as a partner. The program applies to US companies with 50+ full-time employees at peak (contractors excluded); the employee count guide helps you check before you write.

Common questions
Does CAN-SPAM apply to business-to-business email?
It can. The law covers commercial electronic mail and is generally understood not to exempt business recipients. Whether a given message is commercial depends on its primary purpose. Read the FTC's compliance guide and the statute, and ask your counsel about your own email.
Is a one-to-one introduction email exempt from CAN-SPAM?
Not automatically. One-to-one does not by itself remove a message from the law if its primary purpose is commercial. A permissioned introduction the owner asked for is far lower risk than a cold message, but good practice still means honest headers, a clear subject, an address and an opt-out.
What should the opt-out line say?
Keep it simple and honest, for example asking the recipient to reply stop if they do not want further messages, and then honor that request promptly. Confirm the exact requirements in the FTC's guide. Keep a note of who opted out so you do not write again.
Do I have to tell the owner I may be paid?
Yes, as a matter of good practice and the FTC's endorsement principles, which look at connections a reader would not expect. Say in one sentence that you may receive a reward if the company licenses its data and a deal completes. Do not state an amount.
Can I send the same introduction email to many companies?
That is not how the program works and it raises CAN-SPAM and reputation risks. Introductions here are one at a time, with the owner's agreement. Bulk sending and cold sequences are the pattern the law targets, and lead-list sellers are not who the program is for.
