# Pop

> Send-only email tool from Charm with a terminal form for composing and a command-line mode for scripts.

Pop composes and sends email from the terminal, either through a full-screen form or from flags and standard input. It sends through the Resend API or any SMTP server, renders the Markdown body to HTML unless plain text is requested, and can attach files. It cannot read or fetch mail, so it is used next to a mail client or in scripts and pipelines. It is configured entirely with environment variables or flags.
