Mark Awaiting Reply is a free Chrome add-on designed to enhance Gmail's functionality by adding a simple checkbox next to the Send button in the compose window. This feature allows users to easily mark emails that require a reply, ensuring that those messages are automatically BCC'd to the sender's own email address, thus landing in a dedicated 'Waiting' label. The add-on aims to eliminate the common issue of not receiving responses to important emails by streamlining the follow-up process.

With an easy one-time setup and no ongoing subscriptions or accounts required, Mark Awaiting Reply is user-friendly and respects privacy by keeping all data within the browser. It supports multiple Gmail accounts independently and features a first-run setup wizard to guide new users. This tool is ideal for anyone looking to manage their email follow-ups more effectively and avoid the hassle of forgotten replies.
