pop

"Pop" is a software package that allows users to send emails directly from the terminal. It features a text-based user interface and requires a RESEND_API_KEY to use. Users can also set the POP_FROM environment variable to pre-fill the "From" field. Installation can be done through various package managers or by downloading a binary. Pop can be combined with other tools to create email pipelines, such as mods for AI-generated email bodies, gum for choosing email addresses, and invoice for generating and sending invoices. The software is part of the Charm ecosystem, which is built on open source technologies.
