Where it fits
MailOS is useful when email is part of a larger workflow: customer support, sales follow-up, recruiting, personal operations, or developer coordination.
Use case
CLI email automation without brittle browser sessions
Replace one-off scripts and fragile UI automation with stable commands for search, read, draft, and send workflows.
$
npm install -g mailos What this gives you
- Works across common inbox providers
- Produces command output agents can read
- Keeps sensitive sending steps explicit
Example commands
mailos search --subject invoice --days 30mailos stats --days 7mailos send --file update.md --preview Why a CLI helps
The terminal gives agents a stable interface. Instead of navigating visual inbox state, they can search, read, draft, and summarize through clear commands.
How to start
Install MailOS, configure the account you want to automate, then begin with read-only search commands before moving into draft and send flows.
FAQ
Questions before wiring email into an agent workflow
Can MailOS send cli email automation emails automatically?
MailOS supports send commands, but the recommended agent workflow uses draft, preview, dry-run, and confirm steps before final sending.
Does MailOS replace my email client?
No. It complements your existing inbox by giving terminal tools and AI agents a consistent command interface.
Can I use multiple accounts?
Yes. MailOS is designed around explicit account selection so work, personal, and project inboxes can stay separate.
