Do you have a tip or sensitive material to share with CNN? We offer several ways to reach our journalists.
We regularly review submissions, but because we receive a large number, we cannot respond to or investigate every tip.
Anatomy of a good tip
Tips should be newsworthy, meaning they concern systemic problems of timely and broad public interest. The most compelling tips are those that can be corroborated with documentation or evidence.
These channels are not for press releases. To share feedback about something you saw on CNN or CNN.com, use our feedback form.
Before reaching out
Remember that no method is completely secure and what measures you should take depend on how much anonymity you need. Before using any of these apps or tools, consider taking a few extra security precautions, including: considering whether the network you use can be used to identify you or your activity; using a secure web browser or operating system; disabling features that back data up to cloud services; and avoiding using accounts or devices linked to your name, email or phone number.
The Freedom of the Press Foundation offers more detailed guides aimed at maintaining privacy and anonymity.
Regular email is convenient but not secure. Do not use it if your information is sensitive or if you are concerned about someone knowing that you are a source.
For more sensitive tips, you can send email encrypted with Pretty Good Privacy (PGP). Be aware that while the content of PGP-encrypted emails is secure, metadata — such as information about the sender or recipient, time stamps and the subject — is not. Keep in mind that many email providers retain your messages unless you direct otherwise.
Several browser extensions, such as Mailvelope, Enigmail and FlowCrypt, make it easy to use PGP with existing email providers, such as Gmail. You can also use ProtonMail, an email provider that supports PGP.
For additional anonymity, set up a dedicated email address to communicate with us.
Signal is a free app that allows users to make and send encrypted calls and self-destructing text messages, images and videos. The Signal Protocol is end-to-end encrypted, which means only the sender and recipient can access the conversations. Signal does save some information about you, including your phone number, when you signed up and when you were last active, but stores no metadata about your communications. By default, Signal saves your messages on your device unless you configure them to self-destruct.
For additional anonymity, consider setting up a dedicated phone number to use with Signal. You can do this through several services, such as Google Voice, Skype or Twilio, or you can purchase a prepaid SIM card.

WhatsApp is a free app that secures phone calls and text messages using end-to-end encryption and allows you to delete messages even after they’ve been read. The app is owned by Facebook and retains a significant amount of metadata about conversations. However, WhatsApp claims neither it, nor third parties, can see users’ private conversations.

Traditional first-class mail is still among the safest ways to communicate securely.
When sending tips through postal mail don’t include a return address on the letter’s face. (If you’d like us to be able to contact you, include your contact information inside the letter.) Make sure any writing on the letter’s face is typed, not handwritten, and send your letter from a sidewalk mailbox, and not your home, workplace or a post office.
