Pop

TUIMail tool

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.

Use Pop with Forward Email

How Pop fits with a Forward Email mailbox. Replace you@example.com with your alias and the password command with your own. The same settings work with any provider once the server names change.

~/.bashrc (or your shell profile)

# ~/.bashrc or ~/.zshrc
export POP_SMTP_HOST=smtp.forwardemail.net
export POP_SMTP_PORT=465
export POP_SMTP_ENCRYPTION=ssl        # or port 587 with: starttls
export POP_SMTP_USERNAME=you@example.com
export POP_SMTP_PASSWORD="$(pass show email/forwardemail)"
export POP_FROM=you@example.com

# Interactive: pop
# Scripted:    pop < message.md --to friend@example.org --subject "Hello"

Protocol	Server	Port	Security
IMAP	`imap.forwardemail.net`	993	SSL/TLS
POP3	`pop3.forwardemail.net`	995	SSL/TLS
SMTP	`smtp.forwardemail.net`	465	SSL/TLS
SMTP	`smtp.forwardemail.net`	587	STARTTLS

Username: your full alias address, such as you@example.com. Password: the one shown by Generate Password next to the alias in your Forward Email account. Folders: INBOX, Drafts, Sent Mail, Trash, Spam and Archive.

Prefer no config at all? Forward Email's terminal app signs in with your account and has mail, calendar and contacts in one program.
