CAN-SPAM Act Requirements- Physical Address, Unsubscribe Option

This Law likely does not apply to your List, since non-commercial email is not subject to this Law.

However, your messages are sent to a "list" address. Such emails appear to be commercial to an ISP.

Many ISPs have written software to scan incoming emails like this for a valid physical address, an unsubscribe option, etc. If the software does not find these items, the email is rejected.

What we do to avoid rejected emails is described below.

The CAN-SPAM Act (Controlling the Assault of Non-Solicited Pornography and Marketing) is a U.S. Law that established a nationwide set of standards for the sending of commercial email. This law includes 7 main requirements:

  • Don’t use false or misleading header information.
  • Don’t use deceptive subject lines.
  • Identify the message as an ad.
  • Tell recipients where you’re located. *
  • Tell recipients how to opt out of receiving future email from you. **
  • Honor opt-out requests promptly. ***
  • Monitor what others are doing on your behalf.


* Valid physical postal address required

What We Do To Be in Compliance:
We automatically place the physical address at the bottom of outgoing messages, below the footer. You can edit this field to be your own physical address.

If the field is left blank, we use our business address in Houston, Texas.

** Unsubscribe option required

What We Do To Be in Compliance:
Every email message includes the option for Subscribers to unsubscribe.

*** Promptly honoring unsubscribe requests

What We Do To Be in Compliance:
Every request to unsubscribe is completed as soon as received.
