This is a really nice email client designed to send emails from your terminal:
Written in Go. Has a nice TUI:
Or you can do things like:
pop < some-md-file.md --to "hi@mail.com --bcc "yo@mail.com" --subject "This is an important email"
And a nicely formatted email is sent.
By default it uses the https://resend.com/ email service. But, you can also configure a custom SMTP server:
export POP_SMTP_HOST="smtp.example.com"
export POP_SMTP_PORT="587"
export POP_SMTP_USERNAME="you@example.com"
export POP_SMTP_PASSWORD="super-secret"
