Why do I need a mailing address in my emails?

Every email you send from Flodesk must include a complete, valid mailing address. This isn’t optional—it’s a legal and deliverability requirement that helps protect both you and your subscribers.

This article explains why a mailing address is required, what address you can use, and how to update it in your account.

A mailing address is required to comply with anti-spam laws, including the U.S. CAN-SPAM Act and similar regulations worldwide.

These laws apply to all commercial emails, regardless of business size or location.

Including a valid mailing address:

• Confirms that your business is legitimate

• Builds trust with email providers and subscribers

• Helps prevent your emails from being flagged as spam or blocked

Yes.
Even if your business is fully online or doesn’t have a physical storefront, you must still include a mailing address in your emails.

This requirement applies to:

• Online businesses

• Freelancers and solopreneurs

• Creators and service-based businesses

• Side hustles and home-based businesses

You’re not required to use your home address.

Common alternatives include:

• PO Box

• Virtual business address (sometimes called a virtual office address)

Many businesses choose virtual address services because they:

• Provide a professional-looking business address

• Protect personal privacy

• Can often receive and forward mail

Pricing and availability vary by region, so it’s best to research providers and choose what fits your business needs.

If your emails don’t include a valid mailing address:

• Email providers may see your emails as untrustworthy

• Your emails may be blocked or bounced

• Deliverability and inbox placement can suffer

• Spam complaints are more likely

A missing address can directly impact whether your emails reach the inbox at all.

No.
Using a fake address (for example, “123 Smile Street”) can cause serious deliverability issues.

Email providers can detect invalid addresses, and using one may result in:

• Emails being blocked

• Reduced sender reputation

• Long-term inbox placement problems

Always use a real address where you can receive mail.

To update your mailing address:

1. Go to My Account

2. Select Branding

3. Click Company address

4. Update your address and save

This updated address will automatically appear in new emails you create.

Currently, the new mailing address won't sync automatically to published workflows. If the email is already published inside a workflow:

• Pause the workflow

• Open the email in edit mode

• Click Finish to allow the new address to populate

• Re-publish the workflow

You don’t need to change anything else in the email.

• A valid mailing address is legally required in all commercial emails

• This applies to all businesses, including online-only businesses

• PO Boxes and virtual addresses are acceptable alternatives

• Missing or fake addresses can hurt deliverability

• You can update your mailing address anytime in My Account → Branding

Do I legally need a mailing address in my emails?
