Can an ESP allow its users to use the ESP's physical address in marketing emails under CAN-SPAM?

Summary

The CAN-SPAM Act mandates that all commercial emails include a valid physical postal address for the sender. A key question arises for smaller businesses and individuals using email service providers (ESPs): can they use the ESP's physical address instead of their own? While the law states "your" physical address, enforcement often prioritizes severe violations like deceptive headers or missing unsubscribe mechanisms over the exact ownership of the postal address. Many consider using an ESP's address a technical violation, yet its practical consequences are typically minimal, especially for smaller entities.

What email marketers say

Email marketers frequently discuss the practicalities and ambiguities of CAN-SPAM's physical address requirement. Many acknowledge the legal mandate but question its strict enforcement, particularly for small businesses or direct-to-consumer (DTC) brands that may not have traditional physical headquarters. The consensus often leans towards the importance of transparency and general compliance, even if some aspects of the law are perceived as outdated or challenging to implement literally.

What the documentation says

Official documentation for the CAN-SPAM Act consistently outlines the requirement for a valid physical postal address in commercial emails. While it specifies that this can be a street address, a registered PO Box, or a private mailbox, the wording focuses on "your" address. This implies a direct connection to the sender or their designated mail receiver. The intent behind this rule is to provide transparency and a tangible point of contact for recipients who wish to communicate with the sender outside of email, particularly for opting out.
