Outreach you can audit

SS Leader is a B2B cold-outreach platform where the model never writes a freeform email. It fills one paragraph into your own templates and runs every send through an eight-step, fully traced pipeline. Nothing leaves unaudited.

02 · The guarantee

The model never writes
the email

Most AI outreach hands a language model a blank page and hopes. SS Leader does the opposite: the model fills a single paragraph into copy you wrote and approved. That is the difference between outreach you have to police and outreach you can trust.

Template-fill

The model writes one paragraph, the trigger. It is dropped into your owner-verbatim template. Every other line is fixed by construction, so the email cannot drift off-brand or invent a fact.

8-step logic DAG

Suppression, greeting, draft, AI critic, refine, send-gates, render, deliver. The runtime walks a declarative graph held in lockstep with its contract by a drift test.

Covenanted skills

Each step is a skill with a typed, machine-validated covenant. The critic judges only the trigger. The refiner declines rather than ground a fact it cannot verify.

A logic-md pipeline: three reasoning steps linked by typed output contracts, with a quality gate firing a retry loop and a human fallback.
logic-md — typed handoffs, quality gates, halting policy
covenant-md: a skill folder with a fuzzy boundary versus the same skill bound by a typed, validatable COVENANT.md the caller can depend on.

03 · What it does

One pipeline,
end to end

Draft

The drafter fills the trigger paragraph into your template and runs a deterministic validator. No freeform body, ever.

Critic

A second, independent model reviews only the inserted paragraph and returns a pass, warn, or fail verdict.

Refine

A surgical refiner edits just that paragraph and re-checks itself. It declines rather than invent a fact it cannot ground.

Send-safe gates

Opt-out suppression, a one-live-send-per-business lock, per-tenant daily caps, and a banned-phrase hard gate run before anything leaves.

Delivery telemetry

Sent, delivered, opened, clicked, bounced, complained. Svix-verified webhooks land every event against the engagement.

Multi-tenant

Per-tenant templates, voice, send identity, and caps. One platform, isolated tenants, row-level security throughout.

04 · Evidence

Every send leaves a trace

The operator console renders this trace as chips on every draft. Nothing about a send is a black box: each step, verdict, and model is recorded and replayable.

05 · Send safety

Gates before
anything ships

SS Leader is built for South African B2B outreach and treats consent as a hard constraint, not a setting. Every live send clears the same fail-first gates.

GATE · 01

POPIA

Opt-out, checked twice

Suppression runs before any model call and again at the send boundary. An opted-out lead is dropped before a single token is spent.

GATE · 02

One

Live send per business

A per-business lock blocks re-targeting. Nobody gets a second live cold email by accident.

GATE · 03

Caps

Per-tenant daily limits

Live sends are bounded per tenant per day. Volume stays deliberate, never a spray.

GATE · 04

Hard

Banned-phrase gate

A throwing validator at send time blocks forbidden phrasing outright. Test and mock sends are exempt; live sends are not.

06 · Workflow

From lead to tracked send

01

Select

Pick a scored lead in the operator console and choose a hook. The greeting is resolved deterministically, never guessed by the model.

02

Draft & critique

The drafter fills the trigger paragraph into your template. An independent critic reviews only that paragraph and returns a verdict.

03

Refine or approve

On a warn or fail the refiner edits surgically and re-checks. The operator can edit, deep-refine, regenerate, or approve.

04

Send, gated and traced

Suppression, live-lock, daily cap, and banned-phrase gates clear in order. The send and its full trace are persisted; webhooks track delivery.

Built by Single Source

SS Leader is built and run by Single Source Studios, an AI systems integrator based in Durban, South Africa.

We build production AI that solves the problem, not just describes it. SS Leader is that principle applied to cold outreach: every claim the system makes about a send is one you can open and verify.

08 · Why it holds up

Trust the output,
not the vibes

01

Auditable by default

Every send persists a full step-by-step trace: suppression, greeting, draft, critique, refine, gates, render, deliver. Nothing about a send is a black box.

02

It cannot fabricate the pitch

The model fills one paragraph into copy you wrote and approved. The rest of the email is fixed by construction, so it cannot invent a fact or drift off-brand.

03

Consent is a hard gate

POPIA opt-out is enforced before any model call and again at the send boundary. Suppressed leads never reach a live send.

04

Multi-tenant and isolated

Per-tenant templates, voice, send identity, and daily caps, with row-level security throughout. One platform, cleanly separated tenants.
