CAN-SPAM for Cold Email: Where the Official Rules Live

Point US senders at the FTC's CAN-SPAM guidance and at the headers, address, and opt-out their mail still has to get right.

CAN-SPAM applies to commercial email in the United States. The Federal Trade Commission publishes the compliance guide. Use that page for what the headers must not do, what the postal address must be, and how quickly an opt-out must work. This article will not invent a fine or a day-count. Those figures belong to the current official text.

Cold email is commercial if it promotes a product or service. Labelling it a 'quick question' does not change the content. An accurate From name, a real address, and a suppress list you actually apply are the operational core.

What to wire in the send

When someone opts out, every later draft for that person on every channel stops. Sendblox can hold sends for approval and should treat a suppression as final. It cannot decide whether your postal address is real or whether your subject line is deceptive. That is the copy a person is approving.

Before you publish a change for CAN-SPAM, write down the date, the record you edited, and the one message you used as a test. A week later, check whether that test still matches production. Provider rules, DNS includes, and CRM fields all move. A page that was true in general can be wrong on your domain if nobody looked again. Keep the send small until that check is dull. One contact, one objective, a person reading the draft. If the test fails, stop the campaign. Do not widen it to see whether a larger list forgives a broken setup.
