A straightforward Gmail sending tool that handles the messy parts of email composition for you. Automatically deals with RFC 5322 formatting, MIME encoding, and base64 attachment handling so you don't have to think about it. Supports the usual suspects like CC/BCC, HTML content, file attachments up to 25MB, and sending from aliases. The draft mode is handy for preparing emails programmatically without firing them off immediately. It's a write command so Claude will ask before executing, which is exactly what you want when dealing with email.
