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

The Deliverability Engineer

Weighted verdict

Cares about one number nobody publishes honestly: what reaches the inbox. Reads for authentication, IP and domain reputation, bounce discipline and sunsetting. Ignores every advertised delivery rate on principle — the infrastructure either is documented or it is not.

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

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 Deliverability Engineer

Automation is real and documented: flows whose nodes hold a template, a waiting time or a condition branching the flow in two — for example paying versus non-paying customers — with delays configurable down to a welcome mail one minute after signup. The editor backs it with 861-plus responsive templates, custom HTML and in-editor image editing, but I found no public information on A/B testing, send-time optimisation or dynamic content per segment. 1 2 9

Report an error

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 Deliverability Engineer

DMARC sender-verification configuration is documented and described as indispensable for the large providers, and the vendor publishes an explainer on how spam filters work. I found no public information on bounce handling or hard-bounce suppression, complaint loops, dedicated IP options, warm-up or engagement-based sunsetting — the discipline that decides what reaches the inbox is not written down anywhere I can see. 3 4

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 Deliverability Engineer

The way in is published: a tutorial walks through importing subscriber lists from Mailchimp. The way out is not — I found no public information on exporting subscribers with attributes and unsubscribe state, on engagement history, or on documented deletion of a subscriber across records. 7

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 Deliverability Engineer

The integrations page lists multiple native integrations with free downloadable plugins, and an HTTP POST API usable from any programming language is documented for the SMS gateway, with API documentation linked in the footer. I found no public information on webhooks, documented rate limits, a sandbox, or maintained bidirectional integrations with named shop or CRM platforms. 1 8 9

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 Deliverability Engineer

The contracting name is published as Acumbamail SL and a GDPR page exists, but that is the whole trail: I found no public information on jurisdiction, hosting or data residency, ownership, or a subprocessor list. For a criterion this buyer weighs heavily, nothing in the chain from subscription to send is traceable on the published pages. 5 6 9

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 Deliverability Engineer

What is public sits at the edges: a free tier of 2,000 emails/month for life, pay-per-send SMS with referenced rates, non-expiring bonus packs and 5 SMS to trial. No paid contact-tier price, send limits, overage rates or VAT treatment appear on the captured pages, and high-volume pricing is a phone-call conversation — a real invoice cannot be computed from what is published. 4 8 9
