Senderz never resells AI tokens. Every AI feature — the natural-language segment builder, subject-line and email generation, the marketing calendar, the assistant chat — runs on your own provider key, fetched per request and never logged.

​
Supported providers

Claude

Anthropic models via your API key.

Gemini

Google models via your API key.

OpenAI

OpenAI models via your API key.

Custom endpoint

Any AI SDK-compatible provider (OpenAI- or Anthropic-compatible base URL).

​
Configuring

In Settings → AI provider, pick your provider, model and (for custom) base URL, then paste your key. Keys are write-only — the API returns presence flags, never key material.
Keys are stored in a secrets manager keyed by workspace + provider, fetched into request scope, used, and dropped. They’re never cached across requests or written to logs.

​
What AI powers

A tool-using agent over your workspace — contacts, segments, campaigns, flows, analytics, billing, compliance. Read tools by default; optional write tools (draft campaign/segment/flow/template, schedule, create coupon) all go through the normal service layer.
Describe an audience in plain language; the agent verifies its draft against your data and proposes a valid v1 filter.
Generate a full subject + HTML + text email matching your brand kit, and translate between Hebrew and English. Merge tags are never translated.
Propose an editable calendar or 3–8 draft campaigns/flows/segments from a goal. Proposals are never auto-sent — you accept them and they materialise as normal drafts.

​
Safety model

The AI can never bypass compliance. Every AI-initiated action runs through the same pipeline — RLS confines it to your workspace, the approval workflow still gates campaigns, and quiet hours, consent, suppression and the SMS wallet all apply at send time. AI-initiated actions are audit-logged distinctly from UI actions.

​
If your key fails

If your provider returns 401/429/insufficient-quota, the AI surface pauses for your workspace with a clear “fix your API key” banner. There’s no silent fallback to another key — the request fails, because the whole point is that you pay the provider directly.
Product copy uses “your API key”, not “BYOK”. The default models are the capable tiers (quality over latency) for tool-using surfaces.
