  • Why does Boomerang Yahoo need access to my email account?

    Like many email plug-ins, we need access to the full email data to be able to move and send messages. In our queries, we only store the headers of the message (subject, sender, time) so that we can uniquely ID the message you want to schedule. We don't store any message text.

  • Does it mean you have my Yahoo! account password?

    No, we don't have access to your Yahoo! password. You are authorizing us access to your account through Yahoo!'s official OpenID system.

  • Uninstallation

  • Troubleshooting

  • I use Firefox and I'm recieving an authentication error, what now?

    Please ensure that third-party cookies are enabled. Detailed instructions are here.

  • I cannot Boomerang a message. An error occurs during processing.

    This means that Boomerang had trouble reading the email's headers and was unable to uniquely identify the message. If you don't mind sharing the email with us, please forward it to us at We'll look into it and improve Boomerang for a future release.

  • I continue to get Failed Boomeranged Message notifications.

    Make sure that you did not remove your scheduled messages from the Boomerang folder. If you did not remove the scheduled message from the Boomerang folder and the errors still continue to occur, please contact
