Gws Gmail Reply

Replies to Gmail messages while automatically handling all the threading complexity that makes email integration a pain. It sets proper In-Reply-To and References headers, quotes the original message, and preserves the conversation thread without you having to think about it. You can add attachments, CC additional people, or save as a draft instead of sending immediately. The HTML mode preserves inline images and formatting from the original message. If you're building any kind of email automation or assistant that needs to participate in real conversations rather than just blast out notifications, this handles the tedious parts correctly.
