Spam filtering or blocking on ISP servers:
There are many reasons you may not receive our emails; however, if you are not receiving any emails from our site, it is usually due to spam filtering or blocking software on your Internet Service Provider's (ISP) email servers.
Occasionally the ISP's spam filtering software bounces the emails, in which case the sender will receive an email telling him that his email was undeliverable. While we can verify that we have sent an email, we cannot verify whether it reached its destination.
What to do:
Since we cannot control your ISP's spam filtering or blocking software, you should contact your ISP or email service provider's Customer Support and ask them to verify that our website, GunBroker.com, is on your Whitelist (a friendly email list that allows our emails to be ignored by your email account's spam filtering software).
