Update: 5/3/2016
Even though this particular post had not been updated for many years, it got tons of traffic and still continues to do so. It seems a lot of people really, really, really want to contact Netflix. Here is some updated information.
You can call Netflix on the phone and speak loving words to them at the following Netflix customer service phone numbers:
(866) 579-7172
(800) 585-7265
You can also stop by and give them warm hugs at their corporate headquarters:
Netflix, Inc.
100 Winchester Circle
Los Gatos, CA 95032
USA
100 Winchester Circle
Los Gatos, CA 95032
USA
For those of you who prefer to send your love via email, good luck with that. When valid email addresses get discovered and posted on this site, Netflix soon shuts them down. If you want to try your luck, you can always make educated guesses. For example, Netflix’s leaders are listed at http://ir.netflix.com/management.cfm. Using those names, you might be able to come up with a valid email address, like johndoe@netflix.com, john.doe@netflix.com, etc. Emailing a company that clearly does not want to be emailed is very likely to be a big waste of your time. It is just way too easy to filter, block, or delete emails.
Of course, you could always send snail-mail to one of the illustrious leaders at their corporate headquarters. These days people are so surprised by paper correspondence, a person might actually take the time to read an actual letter.
Note: Most of the contacts you will find in the comments section were shut down by 5/3/2016. If you have any helpful new Netflix contact information, please post it here.
