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

The Shop Owner

Weighted verdict

Runs a shop where the newsletter is a revenue channel. Wants the shop connected properly — orders, carts, products flowing in, abandoned-cart and post-purchase flows out — and revenue attributed per campaign. Judges price against contribution, not against a competitor's tier.

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

Scored by The Shop Owner

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 Shop Owner

The visual builder branches on behaviour — if a contact clicks, opens or buys — with eleven trigger types including purchases plus custom events I can fire from my shop through the API or Zapier, and the ready-made cart-abandonment and post-purchase flows are exactly the revenue work I buy this for. A/B tests on subject lines, content, delays and send times come with a statistical-significance calculator and conversions in the workflow analytics, so I can see which flow earns. I found no public information on holdout groups for measuring a flow's true lift. 4 5 3

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 Shop Owner

SPF, DKIM and DMARC are documented with exact record values, a single-SPF merge rule and an upgrade path from p=none to quarantine or reject, and bounce handling is genuinely worked out: hard bounces suppressed automatically, soft bounces retried and reclassified, transactional bounces tracked separately and filterable by recipient domain. I found no public information on complaint-loop handling, dedicated IP options, warm-up or inbox-placement testing, and the 'Up to 99% email deliverability' figure is a marketing number I don't count as infrastructure. 6 7 3 1

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 Shop Owner

Double opt-in exists but you assemble it yourself as an automation with a confirmation mail and a link-clicked condition rather than a documented default, though the consent record is better than a bare timestamp: the action is logged against the subscriber with source and the wording I chose, and the footer unsubscribe removes people automatically. I found no public information on turning open and click tracking off per campaign, on versioned retrievable consent wording, or on retention rules for inactive subscribers — gaps that matter when mailing paying customers. 8 9 3 2

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 Shop Owner

Export covers email, name, phone, email and SMS subscription status, group assignments, custom fields and registration and activity dates in CSV or Excel, filterable down to bounced or unsubscribed subscribers — that is my list leaving intact — and import takes CSV, Excel and text files up to 64MB with custom fields, backed by a free migration service and profile deletion that leaves an audit record of when and why. I found no public information on exporting full engagement history, past campaigns or templates, or on export throttling. 10 11 3

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 Shop Owner

WooCommerce, Shopify, PrestaShop and Jumpseller are named natively, and my shop's events can drive the automations through triggers and custom events via API or Zapier, with behavioural data flowing in for segmentation. The webhooks are the strongest part — eight topics, HMAC signatures with a rotatable secret, retries on timeout, pause and failure monitoring — over a documented bearer-token API with code examples. I found no public information on documented rate limits, a sandbox, or an API versioning and deprecation policy. 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 Shop Owner

The EU-hosting claim — data hosted in the European Union by default on every plan including the free tier, with an Article 28 DPA and a designated DPO — sits in marketing copy, while the privacy policy says only that servers sit in 'a highly secure server environment'. The operator is named as UAB Sender.lt, but I found no public information on a confirmed jurisdiction, ownership, a named data-centre provider, a complete subprocessor list for the sending chain, or certification — only two website widgets and a generic credit-card-processing mention. I weigh this heavily, and marketing-copy residency without a subprocessor list is not something I bank a customer list on. 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 Shop Owner

The one figure I can rely on is the free tier — 'automate up to 15,000 emails/month', no credit card, cancel anytime. Beyond that I found no public prices for paid tiers at all: no contact-tier prices, no send limits, no overage rates, no VAT treatment, so I cannot compute the invoice for the list size my shop actually mails. 'Premium features included No hidden costs or usage limits' is positioning, not a figure I can plan an invoice around. 4 1 3

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.

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.
