Ensure Delivery of Emails

Although the email software we use has a high deliverability rate, sometimes we need your help to ensure delivery of emails from the National Minority Supplier Development Council (NMSDC). If you are concerned that you are not receiving emails you subscribed to, please review the information below.

Whitelisting Instructions

This will tell the inbox that it should expect to receive emails coming from these addresses. Each email client has a different process for adding addresses, so please consult your email client’s help files.

  • Request that your IT Department whitelist our email sending domain: nmsdc.org
    This will tell the email server that it should expect to receive emails from any from address containing this domain.
  • Request that your IT Department whitelist our sending IP address:
    • General Marketing and Communications:,,,,,,,,,,
    • Connections Communities Communications:,,,,,,,,,,, and
  • Open and click links in emails you have received from us. This will help train the inbox to trust emails coming from our addresses and email sending domain.
  • Move our emails found in your spam/junk folder back to the inbox or mark them as not junk/spam. This teaches the inbox where to place that email in the future and helps boost our domain’s sender reputation.

If you have taken these steps and still continue to have problems, please email us at marcom@nmsdc.org and we will try to troubleshoot further.
