You can write from your kitchen table without necessarily putting that address in your marketing emails. Start with the kind of mail you need to receive, then check the postal rules and your email platform's requirements. This is an independent guide, not legal advice or an official government or platform publication.
The key takeaway
For U.S. commercial email, your home address is often not necessary. The CAN-SPAM rule also recognizes an accurately registered USPS PO Box or an accurately registered private mailbox at a commercial mail receiving agency established under USPS regulations. A service calling itself a “virtual address” is not, by itself, enough.
Compare the options
| Option | Privacy and trade-offs | Receiving mail and packages |
|---|---|---|
| Your current home street address | Simple if you already receive mail there, but the footer shares where you live with readers. | Use your existing delivery arrangements; this does not separate reader correspondence from home deliveries. |
| USPS PO Box | Keeps your home address out of the footer. Requires a rental and collecting mail; location and access hours matter. | Receives USPS mail and packages. Do not assume ordinary UPS or FedEx shipments can go there; see the exceptions below. |
| Private or virtual mailbox at a qualifying CMRA | Uses a separate mailing address, but requires registration and identity verification. Ask about fees and how you will collect or receive your mail. | Check the specific location's carrier acceptance, pickup, forwarding and storage terms. Do not assume every virtual-mailbox plan handles packages. |
CMRA means commercial mail receiving agency: a business that accepts U.S. Mail for other people as a service. USPS rules require customer authorization using PS Form 1583 and identity checks. This is a way to separate your public mailing address from home, not an anonymous mailbox.
How to choose
- Decide what you actually need — If you mainly need a newsletter address and occasional letters, start by comparing a nearby PO Box with a registered private mailbox. If packages matter, ask about the carriers and package sizes you expect before choosing.
- Confirm the mailbox qualifies — For a private or virtual mailbox, ask whether the receiving location operates as a CMRA under USPS rules and how your mailbox will be accurately registered. Get the complete address and required mailbox designation from the provider.
- Compare the practical terms — Check current rental charges, pickup access, forwarding and storage terms directly with the location. A convenient address you can reliably use is more useful than one chosen only because its advertised fee looks low.
- Check your platform's instructions — Use the help page for the service that actually sends your newsletter. A shared address offered by one platform is not automatically available on another.
- Update and preview your emails — Once the address is ready, update the relevant footer settings and review your templates, including automated emails. Check the rendered footer rather than only the account settings. Keep other required content, such as the unsubscribe link.
If you are unsure whether your newsletter is commercial, or whether a particular address qualifies, ask a lawyer familiar with your situation. This guide does not decide that for you.
Why the address is there
The U.S. CAN-SPAM Act requires a commercial email message to provide a valid physical postal address of the sender: 15 U.S.C. 7704(a)(5)(A)(iii). That is why marketing-email footers commonly include one. The statute requires the address in the message; email platforms commonly put it in the footer. Statute: https://www.govinfo.gov/content/pkg/USCODE-2024-title15/html/USCODE-2024-title15-chap103-sec7704.htm
The FTC's rule defines that address in 16 CFR 316.2(p): the sender's current street address, a PO Box accurately registered with USPS, or a private mailbox accurately registered with a CMRA established pursuant to USPS regulations. Read the definition at https://www.ecfr.gov/current/title-16/chapter-I/subchapter-C/part-316
This is not a rule that every personal email needs a postal address. Section 316.3 explains how a message's primary purpose is assessed, including emails mixing promotional and other content. A newsletter's label alone does not settle that question. This article covers the address choice, not the whole CAN-SPAM compliance checklist.
What about packages?
UPS and FedEx generally do not deliver ordinary shipments to a regular PO Box. There are service-specific exceptions: UPS says Ground Saver can deliver to U.S. PO Boxes, and FedEx identifies its contract-only Ground Economy service as its domestic PO Box option. Check the actual shipping service rather than relying only on the carrier's name.
Some Post Offices offer Street Addressing: the Post Office street address plus your box number in the prescribed format. USPS says this can receive qualifying packages from private carriers, including UPS and FedEx, subject to availability and USPS mailing standards. It is not available for every box or location. Ask the Post Office and read its agreement before relying on it.
The USPS agreement says Street Addressing cannot be used as your physical residence or place of business in legal documents. It also excludes alcohol, items over 70 pounds and prohibited items, and requires its specified address format, not “Suite” or “Apt.” This is a mailing option, not a replacement home address.
Private mailboxes can be useful for packages, but verify the location's terms. As one concrete example, The UPS Store says its mailbox agreements include package acceptance from all carriers. That is a description of that provider's service, not a promise about every virtual mailbox.
Check your email platform
Mailchimp says its footer address must be somewhere you can receive mail, not an email address or website, and suggests a PO Box if you do not want to share your home. Its default templates pull footer content from your audience details. Start with its footer guide: https://mailchimp.com/help/about-campaign-footers/
For custom-coded Mailchimp footers, check the separate implementation guidance carefully: its customization page includes a “not a post office box” instruction for manually entered addresses, despite the general footer guide recommending PO Boxes. If this affects your setup, ask Mailchimp support how to implement your registered PO Box; do not treat that wording as a change to the federal definition. https://mailchimp.com/help/customize-your-footer-content/
Kit offers current Kit users its own address for email marketing sent through Kit. Its help page says Kit will not monitor, accept or forward your mail or packages there. This is Kit's stated platform option, not a general permission to borrow any company's address or a legal determination about your newsletter. Read the current address and conditions directly before using it: https://help.kit.com/en/articles/2502494-alternatives-for-your-physical-address
