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

The Data Protection Officer

Weighted verdict

Signs off the tool that holds named people and records what each of them opened. Wants double opt-in with a proof that survives a complaint, tracking that can be switched off, and an answer to where the behavioural data lives that does not require a Schrems II argument.

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

Scored by The Data Protection Officer

Campaigns & automation

How this is scored

Building the mail and the journey around it: editor, templates, segmentation, triggered sequences, A/B testing.

0 — One-off broadcasts from a fixed template; no segmentation and no automation of any kind.

3 — A drag-and-drop editor and simple list segmentation, but automation is a single welcome mail and there is no testing.

5 — Reusable templates, attribute and behaviour segmentation, multi-step automations on common triggers, and subject-line A/B testing.

8 — A visual journey builder with branching on behaviour and data, dynamic content per segment, send-time optimisation, and testing that reports significance rather than raw counts.

10 — Journeys treat the whole lifecycle: event-driven entry from other systems, branching on any attribute or event, holdout groups for measurement, and automations a marketer can read months later without a diagram.

Report an error

The Data Protection Officer

A no-code drag-and-drop editor with conditional splits, channel branching, exit conditions and entry on shopping, browsing, form or custom events is a genuine journey builder, and send-time optimisation plus per-message reports in the editor go beyond the middle of the scale. We found no public information on holdout groups or significance reporting for tests, which is what the top of this criterion turns on. 3 4 1

Deliverability infrastructure

How this is scored

Whether the mail arrives — authentication, sending reputation, bounce and complaint handling — judged on what the vendor documents rather than the inbox rate it advertises.

0 — No documentation of authentication or bounce handling; deliverability appears only as a marketing number.

3 — SPF and DKIM setup documented, but no DMARC guidance, no stated bounce policy and shared sending only.

5 — SPF, DKIM and DMARC documented with a custom sending domain, automatic hard-bounce suppression, and complaint-loop handling stated.

8 — The above plus dedicated-IP options with a documented warm-up, seed or inbox-placement testing, engagement-based sunsetting, and published guidance on list hygiene.

10 — Deliverability is operated as a service: reputation monitoring surfaced to the customer, per-domain and per-ISP diagnostics, enforced authentication before first send, and postmaster or blocklist handling the vendor documents doing on the customer's behalf.

Report an error

The Data Protection Officer

SPF, DKIM and DMARC are documented with free domain signing, in-app SPF error guidance, dedicated IP options with a two-to-four-week warm-up schedule, and published hygiene guidance on engaged-contact windows and complaint rates. We found no public information on automatic hard-bounce suppression, complaint-loop handling or inbox-placement testing, which is what the higher rungs of this criterion require. 5 6

List ownership, import & exit

How this is scored

Whether the list and its history remain the sender's: import with attributes intact, full export including engagement history, deletion that executes, and no metering that prices leaving out of reach.

0 — Export is addresses only; engagement history, segments and automations cannot leave.

3 — CSV import and export of subscriber fields, but engagement history and unsubscribe state are not exportable.

5 — Full subscriber export including custom attributes, subscription status and unsubscribe state, plus API access sufficient to sync elsewhere.

8 — Everything exportable in open formats — subscribers, engagement history, campaigns and templates — with documented deletion of a subscriber across all records, and no export throttling.

10 — Exit is a documented feature: full-fidelity export of the whole account, contractual data return, deletion that is evidenced rather than asserted, and migration tooling in both directions.

Report an error

The Data Protection Officer

CSV export covers the full contact record including consent, opt-in and opt-out dates, tags, segments and custom properties, with four export routes, and the processing agreement promises deletion with a certificate or full return at the end of the service. We found no public information on exporting engagement history per campaign, or campaigns and templates out of the account, and deletion is addressed only at contract end rather than documented per subscriber. 9 10 2 1

Integrations & API

How this is scored

The connection surface a newsletter lives on: shop and CRM systems, events in and out, webhooks, and an API somebody can build against without a partner agreement.

0 — No API and no named integrations; the list is maintained by CSV upload.

3 — A handful of native integrations and a read-mostly API, with no webhooks and no documented rate limits.

5 — Named integrations for common shop and CRM systems, a documented REST API with keys, and webhooks for the core subscriber events.

8 — Maintained bidirectional integrations with named systems including at least one major shop platform, event webhooks with retries, documented rate limits, and a sandbox.

10 — The tool is a component rather than a destination: transactional and marketing sending on one API, events flowing both directions, versioned API with a deprecation policy, and integrations the vendor maintains rather than lists.

Report an error

The Data Protection Officer

Eight named commerce platforms including Shopify, 280-plus integrations, and scoped API keys covering contacts, orders, products, carts and custom events in and out give a real build surface without a partner agreement. We found no public information on webhooks, documented rate limits or a sandbox, which a buyer building against this would need documented. 1 12 11

European sovereignty

How this is scored

Where subscriber data and behavioural tracking live, who the contracting entity is, and which subprocessors touch the send. Independently sourced by the sovereignty pipeline; scored here as this buyer weighs it — which in this category is heavily.

0 — US vendor and contracting entity, US hosting, subprocessors unnamed; subscriber behaviour leaves the EU with no stated basis.

3 — EU hosting offered as an option or for storage only, while sending, tracking or support access remains non-EU, or the subprocessor list is absent.

5 — EU hosting as standard and an EU contracting entity, but parts of the chain — sending infrastructure, analytics, support tooling — are non-EU without an explained safeguard.

8 — EU or DACH hosting with a named data-centre provider, EU contracting entity, complete subprocessor list published, and any non-EU processing named with its legal basis.

10 — Sovereign end to end and evidenced: vendor, entity, hosting, sending and every subprocessor in the EU, certification published, and no transfer that needs a Schrems II argument to survive.

Report an error

The Data Protection Officer

The processing agreement names a group of three companies in Vilnius, London and Charleston, South Carolina without saying which one a given customer contracts with, and hosting location is not stated anywhere we captured. The subprocessor list sits in an annex we could not see, and the presence of Standard Contractual Clauses with a UK transfer addendum signals non-EU legs this buyer would have to argue safeguards for. 2

Pricing transparency

How this is scored

Whether a sender can compute the real invoice for their list size and send volume — including overage, extra domains and automation limits — from public pages alone.

0 — No public prices at all; every tier is a sales conversation.

3 — A headline price per contact tier exists, but send limits, overage rates or the tier where automation begins are not stated.

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

8 — Every tier priced publicly with contact and volume limits, overage rates, feature boundaries and VAT treatment stated; only genuinely custom volume lacks a number.

10 — Complete price computability: a calculator producing the annual invoice for a given list size and send frequency, including overage, additional domains and dedicated IPs.

Report an error

The Data Protection Officer

The captured pages show a free tier with full access and no credit card, and that confirmation emails do not count toward a monthly email limit, which confirms limits exist without stating them. No contact-tier price, send limit or overage rate appears, so a real invoice cannot be computed from public information. 1 3 4 7
