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.

Scored by The Deliverability Engineer

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.

The Deliverability Engineer

A visual drag-and-drop journey builder with eleven trigger types plus custom events fired via API or Zapier, If/Else branching on opens, clicks and purchases, and segmentation by location, engagement and any profile field. A/B testing covers subject lines, content, send times and whole workflows, and a statistical significance calculator tells you when a winner is reliable instead of raw counts. I found no public information on holdout groups for measurement, which is the one thing short of the very top of the scale here. 3 4 5

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

SPF, DKIM and DMARC are documented down to exact record values with a verification recheck button and guidance to strengthen DMARC past p=none, and bounce discipline is genuinely good: automatic hard-bounce suppression, soft-bounce retry with suppression after persistent failures, hard and soft rates reported separately, and a domain filter to see whether bounces concentrate on one recipient domain. I ignore the advertised "up to 99% email deliverability" on principle. I found no public information on dedicated IP options, warm-up, seed or inbox-placement testing, engagement-based sunsetting, or complaint-loop handling, which keeps this short of the best-documented setups. 1 3 6 7

Consent, proof & tracking limits

How this is scored

How subscribers arrive and what the sender can prove afterwards: double opt-in, logged consent, unsubscribe handling, and whether open and click tracking can be limited or switched off.

0 — Single opt-in with no consent record; tracking is always on and cannot be disabled.

3 — Double opt-in available but not the default, and the consent record is a timestamp without the source, IP or the wording consented to.

5 — Double opt-in as the documented default with a stored consent record including source and timestamp, one-click unsubscribe, and tracking that can be turned off per campaign.

8 — Consent is reproducible as evidence: the confirmation mail and form wording versioned and retrievable per subscriber, unsubscribe honoured across lists, tracking off-by-default available, and retention rules for inactive subscribers.

10 — Built for the burden of proof: a per-subscriber consent history an authority would accept, documented handling of Art. 15 access and Art. 17 erasure requests, pixel-free and link-tracking-free sending as a supported mode, and preference-centre granularity rather than all-or-nothing.

Report an error

The Deliverability Engineer

Double opt-in is available with a timestamped confirmation and Confirmed/Not-confirmed groups, granular never-pre-ticked consent checkboxes with customizable wording, and a consent action recorded alongside the subscriber record with signup source and audit logging of every submission. But the confirmation flow is something the marketer assembles as an automation rather than a documented default, and I found no public information on versioned form wording retrievable per subscriber, on Art. 15 access or Art. 17 erasure handling, or on any way to switch off open and click tracking — the privacy policy logs click data with no opt-out documented. 2 3 8 9

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

Import handles CSV, Excel and text with custom fields and downloadable templates; export covers contact details, email and SMS subscription status, group assignments, custom fields and registration and activity dates in CSV or Excel, with per-profile export and profile deletion that leaves a clean audit record of when and why. A documented bearer-token API makes syncing elsewhere plausible. I found no public information on exporting engagement history, campaigns or templates, or on export throttling, and the free migration service is evidenced for coming in, not for leaving. 3 10 11 12

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

Named shop and CMS integrations include Shopify, WooCommerce, PrestaShop and WordPress plus Zapier and an MCP server, the API is documented at its own domain with bearer-token auth and code examples, and the webhooks are engineered properly: eight topics including bounces, HMAC signing with a rotatable secret, retries on timeout, pause, and failure and response-time monitoring. I found no public information on documented rate limits, a sandbox, or a versioning and deprecation policy — that is what keeps this from the top of the scale. 4 5 12 13

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 EU-hosting claim lives in marketing copy on the compliance page — subscribers' data "hosted in the European Union by default, no transfer mechanism to evaluate" — while the privacy policy says only that servers sit in "a highly secure server environment," naming no location, provider or region, and no hosting confirmation appears in a DPA or subprocessor list. The operator is UAB Sender.lt with a designated DPO and an Article 28 DPA, but the subprocessor picture is two US companies for website functions, an unnamed credit-card processor, and a third-party web analytics partner the privacy policy explicitly does not cover. For a buyer who weighs this heavily, the hosting assertion is unverified exactly where it would need to be. 2 3

Pricing transparency not rated — the vendor publishes no price

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

The only concrete price figure in the captured pages is the Free Forever plan's 15,000 emails per month; the marketing promises "no hidden costs or usage limits" alongside it. I found no public information on any paid tier price, contact tiers, send limits beyond the free plan, overage rates, VAT treatment, or where automation and other paid features begin. A buyer cannot compute an invoice for their list size from these pages. 1 3 4

European sovereignty — proven facts

1 of 4 dimensions proven

Built only from facts shown on the vendor's own pages. A dimension we could not prove is left open, not scored as zero.

Legal entity	Not determined	—	uncited Report an error
Ownership	Not determined	—	uncited Report an error
Data residency	EU only ⚠ unverified	3/3 pts	3 Report an error
Subprocessors	Not determined	—	uncited Report an error

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. The statement appears only in marketing copy on the GDPR compliance page; the privacy policy (S1) names no server location ('Sender stores its servers in a highly secure server environment') and no hosting provider or region is confirmed in a DPA or subprocessor list.
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.
