A Gmail and Google Inbox extension to help make sure your email ends up in the right hands.
One of my biggest fears when sending an internal email is that I might mistakenly send it to folks outside the company. Guardrails for Gmail and Google Inbox is a lightweight browser extension that fixes that. Guardrails will give you a heads up when you're sending an email to folks outside your organization or mixing external people in with internal contacts. It'll also give you some peace of mind when you're only talking to people in your own organization. This extension is open sourced at https://github.com/michaelschade/guardrails.
