Common questions.
Is NimbusOS just a sending tool?
No. NimbusOS brings audience and contact management, personalization research, sequences, deliverability, reply workflow, oversight, and proposals into an outbound workspace for founders, agencies, and sales teams.
Does everything run without external providers?
No. Sending, mailbox sync, and enrichment depend on connected providers and account setup. Available workflows depend on your workspace configuration, permissions, and enabled integrations.
