Subject: Action Required: Review WHOIS contact data

Given the importance of these emails, more transparency is in order, and 
using shared mailers does open the threat of 'phishing'..

First of all, the sender should clearly show @arin.com,

The originating IPs, should have PTR's reflecting their role in arin 
infrastructure.

host 50.6.74.62
62.74.6.50.in-addr.arpa domain name pointer 50-6-74-62.unifiedlayer.com.
host 50.6.129.163
163.129.6.50.in-addr.arpa domain name pointer 50-6-129-163.unifiedlayer.com

These are operated by Newfold Digital?

IMHO, a better job can be done on these mailings, and the use of shared 
services can open doors to problems, including at the least ending up in 
people's spam folders.. and have them miss such an important notice.
