| Edit: I missed the transactional part here. Transactional emails are excluded from CAN-SPAM. There's a test to figure out which is which: http://www.the-dma.org/press/PrimaryPurposeFactSheet.pdf It's shitty UX regardless of whether it's a violation of law, IMO. Original: It's a violation of CAN-SPAM law to put unsubscribe behind a login process. Asking for a password violates the requirement that no additional PII except for the email be required to process the opt-out. From the FTC: Honor opt-out requests promptly. Any opt-out mechanism you offer must be able to process opt-out requests for at least 30 days after you send your message. You must honor a recipient’s opt-out request within 10 business days. You can’t charge a fee, require the recipient to give you any personally identifying information beyond an email address, or make the recipient take any step other than sending a reply email or visiting a single page on an Internet website as a condition for honoring an opt-out request. http://www.business.ftc.gov/documents/bus61-can-spam-act-com... |
