Fight back against harassment.

Put a squad of trusted friends, volunteers, or paid moderators between the world and your inbox.

Messages only reach you if your squad approves it.

Together, the members of your squad can weather harassment so that you don't feel overwhelmed.

How does it work?

You can use Squadbox in both of the following ways:

A. You are experiencing harassment on your current email account and want to get some of your emails moderated by your squad. We help you set up filters on your email so that suspicious emails get forwarded to members of your squad. They determine which emails are harassment and which can be forwarded back to your inbox.

B. You need an email address to give out to strangers or post publicly, but want to avoid receiving harassing messages. We give you a @squadbox account to use. Emails to that address get sent to members of your squad. They determine which emails are harassment and which can be forwarded to your inbox.
