Electronic Communication Allowlisting Instructions

In order to ensure receipt of messaging from IANA, and to prevent SPAM filtering, please "allowlist" the IANA domain, including the iana@intermodal.org email address. Different email clients require different allowlisting steps - please find instructions for major email clients below. By following the steps outlined for your email client you will continue to receive important member communications from IANA.

In cases where deliverability issues persists or if you have questions, please contact Art Cleaver at acleaver@intermodal.org for further assistance.
