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

The Data Protection Officer

Weighted verdict

Sees a profiling system, not a mailing tool. Wants consent reproducible per person, tracking that can be switched off for someone who never agreed to it, deletion that removes derived scores as well as raw events, and scoring documented well enough to assess under Art. 22.

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

Scored by The Data Protection Officer

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.

Report an error

The Data Protection Officer

A visual workflow builder is named and behavioural triggers are marketed for activation, onboarding, retention and cross-sell flows, which evidences multi-step automation exists. We found no public information on waits, entry and exit conditions, per-contact journey state, or what happens when journeys collide, so the parts that decide whether orchestration survives contact with reality are unevidenced. 1

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 Data Protection Officer

Retention messaging that responds to churn-risk signals implies engagement-based targeting, but we found no public information on scoring models, decay, lifecycle stages, or routing to owners and teams. Nothing here documents any decision about a lead, which is itself the finding for a scoring capability. 1

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 Data Protection Officer

Six channels are listed — email, mobile, in-app messages, push, SMS and WhatsApp — on a single platform that personalises cross-sell campaigns on product usage, which is behavioural rather than stored-field personalisation. We found no public information on shared suppression or unsubscribe handling across channels, ad-audience sync, or cross-channel frequency capping, so the one-profile claim rests on marketing copy alone. 1

Report an error

Consent, tracking & profiling

How this is scored

The platform builds behavioural profiles of named people. Consent capture and proof, tracking that can be limited, retention, and whether automated decisions about individuals are documented and contestable.

0 — Tracking always on and undocumented, single opt-in, no consent record, no retention rule, no way to exclude a person from profiling.

3 — Double opt-in available with a timestamp, cookie tracking that cannot be disabled per contact, and retention described as the customer's problem.

5 — Double opt-in as documented default with a stored consent record including source, per-channel consent states, tracking switchable per contact, and stated retention for inactive records.

8 — Consent reproducible as evidence with the wording versioned, profiling suppressible per person, retention executed per data category, documented handling of access and erasure requests including derived scores, and a cookieless or first-party tracking mode.

10 — Built for the accountability principle: a per-contact history of what was tracked, scored and decided, automated decision-making documented well enough to support an Art. 22 assessment, profiling off by default for anyone who has not consented to it, and deletion that removes derived scores as well as raw events.

Report an error

The Data Protection Officer

The platform builds behavioural profiles of named people — behavioural triggers, churn-risk signals, product-usage personalisation — and claims GDPR compliance and a Trust Center, but we found no public information on consent records, double opt-in, per-contact tracking switches, retention rules, or handling of access and erasure requests including derived scores. For a profiling system this silence is decisive: nothing on the captured pages lets a buyer reproduce consent or suppress profiling for a person who never agreed to it. 1

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 Data Protection Officer

Custom objects, a data warehouse, data activation, anonymous messages and a published API reference are evidenced, which shows a real data model rather than CSV exchange. We found no public information on sync with any named CRM, field mapping, deduplication or conflict rules, or identity resolution between anonymous and known states — the join that decides the implementation is entirely unevidenced. 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 Data Protection Officer

The only contracting entity on record is Peaberry Software, Inc., and no sovereignty attributes exist for this vendor — we found no public information on hosting location, an EU contracting entity, subprocessors, or the legal basis for any transfer. Certifications such as ISO 27001 and GDPR speak to a security and compliance posture, not to where behavioural profiles of EU residents are processed, and given the profiling that gap weighs heavily. 1

Pricing transparency not rated — the vendor publishes no price

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 Data Protection Officer

Only trial terms are public — fourteen days free, no credit card required — and we found no public information on tier prices, contact or send limits, feature boundaries, overage, or the cost of the hands-on implementation the page itself advertises. A buyer cannot compute any invoice for their contact base from these pages, and the tier where automation begins is unstated. 1

Where this could be wrong

Evidence ages. The oldest capture behind this page is from 29 Sep 2026. Vendors change pricing and policies without notice; every fact reflects its source as of the capture date shown in the registry.
Weak sourcing — Data residency, Subprocessors. Not confirmed on the vendor’s own pages as captured.
AI can misread a source. Extraction and judgement are automated; a citation guarantees traceability, not infallibility. If something here is wrong, say so — no account needed, every report is decided within 5 business days, and accepted corrections are published.
