Read this page as one judge. Each weighs the same scores by what they care about.

The Lifecycle Marketer

Weighted verdict

Thinks in cohorts and retention rather than in campaigns. Wants frequency capping across every journey, holdout groups so the effect is measurable, and personalisation drawn from the behavioural record rather than assembled by hand.

Same scores as the panel view — this lens weights them the way this judge cares.

Scored by The Lifecycle Marketer

Journeys & orchestration

How this is scored

Multi-step automation: triggers, branching, waits, and — the part that decides whether it survives contact with reality — what happens when journeys collide.

0 — Autoresponders on a single trigger; no branching, no waits, no conditions.

3 — Linear sequences with simple conditions, one entry trigger per journey, and no visibility into where a contact currently sits.

5 — A visual builder with branching on attributes and behaviour, waits and goals, entry and exit conditions, and per-contact journey state visible.

8 — Event-driven entry from external systems, frequency capping and suppression across journeys, priority when a contact qualifies for several, versioning of a live journey, and testing against real records.

10 — Orchestration is coherent across the whole programme: one decision layer deciding what a person receives next regardless of which journey wants to send it, holdout groups for measurement, and a journey a colleague can read months later without a diagram.

The Lifecycle Marketer

Flows exist as objects the AI agent can analyse and omnichannel campaigns launch across email, SMS, push, WhatsApp and web, but the evidence says nothing about branching, waits, frequency capping across journeys, priority on collision, versioning or holdouts — the parts that decide whether automation survives contact with reality. Even linear-sequence structure is inferred from the word 'Flows' rather than evidenced, so this sits at the bottom of the linear band. 1 2

Lead scoring, routing & lifecycle

How this is scored

Scoring, qualification and handover to sales — including whether the customer can explain to a lead why the system decided what it decided.

0 — No scoring or lifecycle model; every contact is treated alike.

3 — A single additive score with fixed rules, no decay, no lifecycle stages and no routing.

5 — Configurable scoring on attributes and behaviour with decay, lifecycle stages, and routing to owners or teams with notification.

8 — Multiple scoring models per product or region, negative scoring, account-level scoring alongside contact-level, SLA on follow-up, and score history visible per contact.

10 — Scoring is explainable and accountable: the contribution of each signal visible per record, model changes versioned with their effect on the funnel, routing rules auditable, and predictive scoring — where offered — documented well enough for a DPO to assess it as automated decision-making.

Report an error

The Lifecycle Marketer

Nothing in the evidence evidences scoring, decay, lifecycle stages or handover to sales — segments and a unified profile exist, but segmentation is not scoring, and 'basic segmentation' in the free tier is the only lifecycle-adjacent fact. For a product calling itself 'the autonomous B2C CRM', total silence on how a lead qualifies is itself information: as far as this evidence goes, every contact is treated alike. 1 2

Channels & personalisation

How this is scored

What the platform can actually send and personalise: email, SMS, push, on-site content, ads audiences — judged on what shares one profile and one suppression list.

0 — Email only.

3 — Email plus one further channel, managed separately with its own list and no shared suppression.

5 — Email, SMS or push and web forms driven from one contact profile, with dynamic content blocks and shared unsubscribe handling.

8 — The above plus on-site personalisation, ad-audience sync to the major networks, cross-channel frequency capping, and content personalised on behaviour rather than only on stored fields.

10 — Channel is a delivery detail: one profile and one consent state across every channel, next-best-channel selection, and personalisation that draws on the full behavioural record without the marketer assembling it by hand.

Report an error

The Lifecycle Marketer

Email, SMS, RCS, push, WhatsApp, web events, reviews and social all hang off one customer profile with native WhatsApp and no third-party bridge — that clears the one-profile bar comfortably. But there is no evidence of cross-channel frequency capping, shared suppression or ad-audience sync, which is precisely what I need before letting six-plus channels loose on one cohort, so it stalls short of the next anchor. 1 2

CRM integration & data model

How this is scored

The join that decides the implementation: how the platform and the CRM stay in agreement about who a person is, and what happens when they disagree.

0 — CSV import and export; no CRM integration and no identity resolution.

3 — One-way sync into a named CRM on a schedule, with duplicates resolved by hand and no conflict rules.

5 — Bidirectional sync with at least one major CRM, field mapping, deduplication rules, and a sync error log somebody can act on.

8 — Configurable conflict resolution per field, account and contact objects both modelled, custom objects supported, near-real-time sync with retry, and a documented API with rate limits.

10 — One record, two systems, no ambiguity: identity resolution across anonymous and known states, field-level ownership defined per system, replay of failed syncs, and a data model the customer can extend without vendor services.

Report an error

The Lifecycle Marketer

Klaviyo positions itself as the CRM, with a real-time unified customer profile, 350+ integrations and a full API/webhook/SDK/warehouse surface — the breadth is real. But the evidence is silent on sync direction, field mapping, conflict resolution, deduplication and sync error handling, which is the join that decides implementations, so it lands between 'one-way sync' and the bidirectional anchor without evidencing either. 1

European sovereignty

How this is scored

Where behavioural profiles of named EU residents are processed, who the contracting entity is, and which subprocessors see them. Independently sourced by the sovereignty pipeline; scored here as this buyer weighs it — which given the profiling is heavily.

0 — Non-EU vendor and contracting entity, hosting unstated or non-EU, subprocessors unnamed, behavioural data leaving the EU with no stated basis.

3 — EU data residency for storage while tracking, sending or support access remain non-EU, or the contracting entity sits outside the EU.

5 — EU hosting as standard and an EU contracting entity, but parts of the chain — tracking scripts, AI scoring, analytics — are non-EU without an explained safeguard.

8 — EU hosting on named infrastructure, EU contracting entity, complete subprocessor list published, and any non-EU processing named with its legal basis.

10 — Sovereign end to end and evidenced: every profile, event and derived score processed in the EU by European subprocessors, certification published, and no transfer requiring a Schrems II argument to survive.

Report an error

The Lifecycle Marketer

Klaviyo, Inc. of Boston is the contracting entity, hosting is an unnamed 'cloud hosting provider', storage and processing run through the US and UK, and the subprocessor list is unpublished — transfers rest on the EU-US Data Privacy Framework and SCCs, which is exactly the Schrems II argument a behavioural profiling programme should not have to make. For named EU shoppers' profiles, this is a hair above the floor. 3 1

Pricing transparency

How this is scored

Whether a buyer can compute the real annual invoice for their contact base and send volume — including the tier where automation actually begins, overage, and mandatory onboarding — from public pages alone.

0 — No public prices at all; every tier is a sales conversation, and onboarding fees are never mentioned.

3 — A contact-tier headline exists, but the tier where journeys, scoring or CRM sync begin is unstated, as is any mandatory implementation fee.

5 — Contact-tier prices public with billing period and send limits stated, but at least one commonly needed capability sits in an unpriced enterprise tier.

8 — Every tier priced publicly with contact and volume limits, feature boundaries, overage rates, onboarding costs, minimum term and VAT treatment stated.

10 — Complete price computability: annual invoice derivable for a given contact count, send volume and feature set, including overage, additional users and any implementation fee stated outright.

Report an error

The Lifecycle Marketer

The free tier is fully specified — 500 emails/month, $5 of mobile messaging, 10,000 Composer credits, 60 days of email support — but no paid price figure exists anywhere in the evidence, only a 'contacts plus channels' basis and custom enterprise quotes. I cannot compute the invoice for the tier where flows, WhatsApp or the data platform actually begin, and onboarding fees, overage and VAT treatment are never mentioned. 1 2
