 ## Email Communication Policy
 
 We tend to use the subject line tag "[PSL notification]" in all Public Suffix List communications. For effective spam filtering, you can create a case-insensitive filter to allow only emails with exact "[PSL notification]" in the subject line. If you choose to set up such a filter in your email application, please verify the filter is implemented correctly and test it thoroughly to ensure you don't accidentally miss important communications from us.
