Comcast internet has been very over-zealous about blocking spam, including thousands of legitimate membership e-mails from NACHI.ORG. Though we are in constant contact with Comcast to resolve the issue, requests from fee-paying Comcast subscribers are much more effective than requests from a 3rd party. If you have not been able to receive your membership material or message board notices from InterNACHI at a Comcast e-mail address, please follow these simple steps to alert them to the problem.
