Frequently asked questions

MailNox is a local-first desktop app for cold email and email marketing. It combines everyday email, campaigns, contacts, validation, warmup, multi-account sending, deliverability checks, analytics and campaign replies in one workspace.

MailNox is built for cold outreach and marketing campaigns from your real mailboxes — not a mass ESP or full marketing-automation suite. Prospecting, follow-up, and list-based campaigns are first-class; everyday email stays in the same app.

Replies return to the normal MailNox inbox as real email conversations. Campaign name, sender identity, recipient, group and original subject stay attached so you can continue the thread.

Yes. A campaign can use multiple approved sender identities. Adaptive Send distributes eligible recipients across that pool while respecting per-sender, provider and domain limits, with a finish-time estimate on the Senders step.

Yes. Warmup uses a diverse seed pool to ramp senders before heavy volume. Email validation offers quick local checks and optional paid credits; suppression and unsubscribe keep lists clean.

Mailbox data, contacts, campaign drafts, templates, search and supported AI stay local to your device. MailNox Cloud is used only for features that need a public endpoint, such as unsubscribe and optional open or click tracking.

No. MailNox helps you check validation, authentication, suppression, warmup readiness, bounces and campaign preflight before you send. It respects provider limits and does not promise inbox placement.

Marketers, agencies, growth teams, founders and operators who run cold or marketing outreach and want replies in the same desktop inbox they work from every day.

No. MailNox connects to the email accounts you already use and sends campaigns through those sender identities.

Gmail itself is a web and mobile product. MailNox is a Windows desktop email client that connects to supported Gmail accounts, so campaigns and everyday mail can stay in one local workspace.

Yes. MailNox is designed around multiple accounts and multiple sender identities, so everyday mail and campaigns can share one desktop workspace.

No. MailNox is a client, not a mailbox host. You keep your existing Gmail, Microsoft, or IMAP/SMTP accounts as supported by the product.

No. Supported intelligence can run on your device. Optional cloud models are configurable, and using them does not mean uploading your mailbox by default.

Downloaded mail, contacts and campaign drafts are designed to remain available on the device. Sending, provider sync, unsubscribe endpoints and optional tracking require connectivity.

Windows is available now as a 64-bit .exe and .msi from the download page. macOS and Linux follow the same architecture and are not published yet.

MailNox's provider architecture is designed for Microsoft accounts through supported Microsoft integration, alongside Gmail and IMAP/SMTP where supported.

MailNox supports standard email-provider integration through IMAP/SMTP where supported, including common hosts and self-hosted mailboxes that speak those protocols.

Views filter, group, and sort conversations without forcing you to reorganize the underlying mailbox. One conversation can appear in multiple Views without being copied or moved.

Unread does not mean important. Needs Your Attention is a focused workspace for conversations that may require action—questions, decisions, deadlines, commitments, or a customer waiting—using mailbox signals plus semantic understanding.

Yes. MailNox supports templates, snippets, variables, and Spintax. You can also Generate Spintax with the on-device local model in the template editor. Variation lives in the template; you review the final email before sending.

Adaptive Send distributes eligible recipients across a pool of approved sender identities while respecting per-sender, provider, and domain limits. The Senders step shows a finish-time estimate based on audience size, caps, and your send window.

Yes. Set organization name and physical postal address under Settings → Marketing. Preflight requires it for the compliance footer and automatic Unsubscribe injection.

Yes. Undo Send gives a configurable moment to catch mistakes. Scheduled Send lets you write now and deliver later. Snooze brings a thread back at a chosen time.

MailNox combines fast local full-text search with semantic and natural-language discovery, plus Gmail-style operators, attachment-aware search, and cross-account search of downloaded mail.

MailNox includes email-native Tasks, Waiting, and follow-ups attached to conversations, plus Google Calendar views where configured. It is not a standalone CRM or generic project manager.

No. MailNox is designed to store credentials using OS secure storage, with encrypted local-data architecture for mailbox state and attachments. OAuth for Gmail uses PKCE rather than embedding a privileged server secret in the client.

Remote images are controlled by default. MailNox is designed to sanitize HTML, render messages in a sandbox, flag phishing indicators, and show authentication signals such as SPF, DKIM, and DMARC where available.

MailNox does not require sending your mailbox to an AI vendor. Local intelligence is designed for supported tasks on-device. If you configure an optional cloud model, that boundary should stay explicit—and you should review that provider's own training policy.

MailNox is designed to support local models for appropriate intelligence tasks. Cloud AI remains optional where supported and configured.

Where the provider supports it, MailNox is designed to use native change notifications, with reconciliation so missed events are recovered. Desktop notifications can fire for eligible new mail.

MailNox is a licensed desktop product. After install, the app registers the device, then activates a licence against an allowed device slot. First launch can happen offline; registration completes when connectivity returns.

MailNox is proprietary software owned by Thetawave Technologies. It is a commercially licensed desktop workspace (licensed, not sold). Public plan details are published with commercial release.

No. Mail stays with your email provider. MailNox keeps a local copy of downloaded mail for speed, search, and offline use. Removing the app does not delete the mailbox at Gmail, Microsoft, or your IMAP host.

No. MailNox is a native Windows workspace (Tauri + Rust), not a WebView wrapper. It downloads supported mail into a local database so search, Views, and intelligence run on your machine.

Gmail uses OAuth with PKCE rather than your password. MailNox is designed so you connect with Google credentials you control—typically an OAuth client ID you create in Google Cloud—instead of sending a MailNox server your Gmail password.

Yes. Optional cloud writing and summaries can use a key you provide for supported providers. Local Ollama or LM Studio, and on-device models where installed, are designed for supported intelligence without sending mail to those APIs.

Yes. Mail rules can auto-label, archive, star, or mark read. You can pin or mute threads. A Kanban board (Todo / Waiting / Done) sits alongside email-native tasks and follow-ups.

Where supported, MailNox can group newsletters by sender and hold them until a delivery schedule you choose, plus one-click unsubscribe when List-Unsubscribe headers are present.

Google Calendar month, week, and day views are designed for configured Gmail accounts. IMAP accounts can connect a CalDAV server where you set it up. MailNox is not a full Google Workspace suite replacement.
