FAQ
Questions before wiring email into an agent workflow
Can MailOS send Mutt 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.
