FREQUENTLY ASKED QUESTIONS
Everything you need to know before putting email on autopilot.
Does Banger handle both inbound and outbound work email?
Yes. Banger keeps inbound and outbound in one system. The inbox reply stays connected to the transactional send, lifecycle flow, or campaign that started the conversation, sharing context, identity, deliverability, and control.
How does Banger achieve best-in-class deliverability?
Deliverability is a core part of Banger. We are deliverability experts, and we built proprietary checks for authentication, domain health and reputation, bounces, complaints, suppression, unsubscribes, and sending limits. You get expert guidance and guardrails even if deliverability is not your specialty.
Can agents use Banger from Claude Code, Cursor, ChatGPT, Hermes, or OpenClaw?
Yes. CLI, MCP, SDK, and API give agents a stable interface to read, prepare, and operate email inside the permissions you define.
Does Banger have a public API, SDK, webhooks, and MCP?
Yes. The platform is built to be integrated by developers and operated by agents, with API, SDK, CLI, webhooks, and MCP as surfaces of the same system.
Can I use Banger for transactional and marketing email?
Yes. Connect company domains once, create mailboxes for teams, workflows, projects, customer queues, or agents, send sign-in codes, receipts, alerts, onboarding, and notifications by API, automate welcome, nurture, activation, retention, and winback from events, and run newsletters, launches, announcements, segments, and performance analysis.
Is Banger headless, or can my team manage email in a visual app?
Banger is not headless-only. Agents work through MCP, CLI, SDK, or API while your team sees the work and takes over in the same visual app used for every company mailbox. Read and reply like a regular inbox, inspect what agents changed, fine-edit templates and campaigns, review audiences and delivery, or approve sends. You get speed without creating a parallel inbox, audit trail, or source of truth.
How do approvals and deterministic rules work?
The agent can interpret context and prepare the work. Before every sensitive action, Banger’s engine applies permissions, approvals, schedules, limits, suppression, compliance, and delivery rules. Those policies stay predictable even when the agent improvises.
Is my email content used to train models?
No. Banger does not sell your data or use your email content to train models. Personally identifiable information (PII) is removed before any call to an AI provider.
Who decides what an agent can access?
You do. Access is scoped by workspace, mailbox, and action. An agent can draft for support@ without seeing founders@ or receiving permission to send.
