Norbelys is a multi-tenant cold-email platform. Workspaces connect mailboxes, write campaigns with variants, send through SMTP, and track opens and clicks.

Start with [shared-domain sending](/sending-domains) to connect SMTP once, configure branded tracking and send your first campaign through the API. Read [deliverability and sending policy](/deliverability) before increasing volume. The [API reference](/reference) is generated from the deployed contract.

Use [inbox and delivery feedback](/inbox-feedback) to connect the hosted provider, inspect IMAP checkpoints, distinguish submission from delivery, and handle bounces, complaints and opt-outs.

Read [campaign content and runtime AI](/campaign-content) for inline variants, bounded MiniJinja personalization and per-message generation without public template or AI-job resources.

Use [text, native HTML and Zapier](/email-content) to write ordinary text or supply your own email design through the same API.

Set [campaign hours, timezone and tracking](/campaign-settings), including the workspace timezone default and HTML delivery without open pixels or rewritten links.

Use [people and campaign audiences](/people-and-audiences) to import CSV files, combine groups and segments, add individual contacts and page through precise contact selections.

Use [direct email and dynamic sender pools](/direct-email-and-sender-pools) for standalone HTML, multiple To/CC/BCC recipients, request variables and automatic mailbox selection by tag.

Connect an AI client through [MCP with OAuth or an API key](/mcp).

Configure [sender profiles, signatures and BCC](/sender-profiles) for reusable mailbox defaults and explicit sender, recipient and campaign variables.
