CAN-SPAM Compliance
Last updated: 10 October 2026
Who the law binds
The CAN-SPAM Act of 2003 is the United States' law on commercial email. It applies to any email whose main purpose is to advertise or promote something, wherever the sender is, if the recipient is in the US. It binds the sender: you. SplashSend is built so that the mechanical parts of complying happen by default, and this page says exactly which parts those are, and which are still yours.
What the product does
Accurate headers
The From name is yours. The From address is on your own verified domain, or on our shared sending domain with your name, with replies going to the address you set. We never disguise the origin of an email.
The postal address
CAN-SPAM requires a valid postal address in every commercial email. A street address counts, and so does a PO box registered with the US Postal Service or a private mailbox at a commercial mail receiving agency. Every header and footer SplashSend provides carries your business address, filled in from Setup. If you haven't entered one, or your design leaves it out, we warn you before a campaign sends and on the Cruise page, and the email can still go out without it.
Unsubscribe
Every marketing email carries an unsubscribe link, and the List-Unsubscribe headers that let Gmail, Apple Mail and Outlook show their own unsubscribe button. The law allows ten business days to honour an opt-out; ours takes effect the moment the link or button is used, and the person receives nothing further from your account.
Bounces and complaints
Addresses that hard-bounce, or bounce repeatedly, are suppressed automatically, and anyone who reports one of your emails as spam is unsubscribed and suppressed, so continued sending to unwilling or invalid addresses cannot happen by accident.
What stays yours
- Your postal address has to be in every email you send to people in the US. Add it in Setup, and keep the address block in your footer.
- Subject lines must not mislead about what is in the email. Our suggestions are suggestions; the line you send is your choice.
- Identifying an advertisement where the law requires it is done in your content.
- Opt-outs made elsewhere, such as a reply asking to stop, must be honoured within ten business days across every list you hold; SplashSend can only act on the ones it sees.
- Your list must be one you are allowed to email. Purchased lists are against our Terms.
Penalties
Each email that breaks the Act can carry a civil penalty of more than $50,000, a figure the Federal Trade Commission adjusts for inflation every year. The FTC enforces it, and email providers act on complaints long before the FTC does, which is why the suppression above matters as much as the law.
