We want to hear from you! If you can’t find what you’re looking for below, email cenfeedback@acs.org, and we’ll be happy to help.

Submit a letter to the editor for publication

Readers are invited to submit letters to the editor to be considered for publication in our weekly magazine. We read every letter we receive, and we appreciate the views of ACS members and others who take the time to send us their thoughts. Because of the volume of letters we receive, we cannot publish every letter, and we cannot respond to the authors of letters we don’t publish. 

Letters should be 400 words or fewer and should include the writer's full name, address, email address, and telephone number. Letters may be edited for length, clarity, and C&EN style. Send your letter via email to edit.cen@acs.org.

Please note: 

• We don't publish a letter by the same writer more than once every 3 months.

• We don’t publish letters that are primarily intended to advance commercial ends.

• We don’t publish letters that are defamatory or ones that contain ad hominem criticism of a C&EN reporter, C&EN, or a subject of our coverage.

• The letter must not have been submitted to or published by any other media outlet or posted as comments or feedback on other websites.

• The letter should appear in the body of the email rather than as an attachment.

Request a correction or send feedback

Correction requests and general feedback may be sent to cenfeedback@acs.org.

Send a news tip

If you’d like to share news with us, you can contact any of our reporters and editors directly by email or phone. Some of our staffers also have Signal accounts for secure messaging.

Share tips or documents securely with C&EN

Do you have information or evidence about people in industry, government, or academia doing the wrong thing? Here’s how to let us know while protecting yourself, although no system is 100% secure.

US Postal Service: One of the most secure ways to communicate is via US postal mail without a return address. You can send us paper materials or digital files on a thumb drive. You can address the package to a specific reporter or simply to Chemical & Engineering News. Preferably, drop the package into an out-of-the-way sidewalk box rather than go to a post office. C&EN’s mailing address is C&EN Editors, 1155 16th St. NW, Washington, DC 20036.

ProtonMail: ProtonMail is an easy-to-use encrypted email service that encrypts messages and attachments—but not header or subject information—in transit and on ProtonMail servers. You need to sign up for your own ProtonMail account to encrypt messages you send. You can use the service through a web browser or a phone app. Go to ProtonMail's website to read more about what it does and does not encrypt. C&EN’s ProtonMail account is contactcen@protonmail.com.

Notes: If you want to call us or use a messaging or email app, the most secure approach is to purchase a separate prepaid phone with cash. If you prefer to email from a personal computer, take it to a public Wi-Fi network, such as one at a coffee shop. Or use a public computer in a location that you don't normally frequent.
