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

The Integrator

Weighted verdict

Has to wire this into a stack that already exists. Wants a documented API with rate limits, webhooks that retry, a sandbox and a deprecation policy. Treats a partner-form integration page as a missing API, and reads "Zapier supported" as an outsourced one.

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

Scored by The Integrator

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 Integrator

The segmentation is genuinely grown-up — engagement, geography, time zone, purchase history and signup source, combinable with custom fields and auto-updating — and automations scale from three on the free tier to unlimited with multiple triggers, with a webhook action available inside the workflow. What keeps this off the upper rungs is testing and journey sophistication: I found no public information on subject-line A/B testing, dynamic per-segment content or send-time optimisation, and the only A/B testing the pages describe is PostHog analysing MailerLite's own product usage. 2 6 14

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 Integrator

SPF, DKIM and custom-domain authentication are documented down to the CNAME and TXT records with an automatic setup path, and bounce handling is precise: hard bounces auto-removed, three consecutive soft bounces promoted to hard. I found no public information on DMARC guidance, complaint-loop handling, dedicated-IP warm-up or inbox-placement testing; list verification is referred out to a separate tool, and the dedicated IP appears only in the custom-priced tier. 2 7 8

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 Integrator

Double opt-in is on by default on forms and separately togglable for API and integrations, with per-form confirmation mails, redirects and a documented parameter flow for existing subscribers. Unsubscribe is documented as an opt-out link in every mail, but I found no public information on one-click specifics, on a stored consent record showing source and the wording consented to, or on switching open and click tracking off; the preference centre arrives one paid tier up. 3 2 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 Integrator

Import comes from CSV, Excel paste, single adds, the API and a direct Mailchimp path with field mapping and duplicate cleanup, and export covers chosen columns including groups, status segments down to unsubscribed, bounced and spam complaints, per-campaign engagement reports and automation activity, in CSV. I found no public information on exporting campaigns and templates, on documented deletion of a single subscriber across all records, or on export throttling — export is administrators-only, and the migration help on the pages I have points to moving in. 1 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 Integrator

This is what I came for: fourteen subscriber and campaign webhook events managed through create, read, update and delete endpoints, signed with HMAC-SHA256, retried three times at 10, 100 and 1000 seconds inside a documented 3-second response window, plus batch requests that reference the platform's rate limits — though the captured pages do not state the limit figures themselves. Native Shopify, WooCommerce and WordPress integrations and an MCP server sit next to a real developer API, but I found no public information on a sandbox or an API versioning and deprecation policy, and transactional sending requires a separate MailerSend account rather than one API. 1 1 3 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 Integrator

For an EEA billing address the contract sits with MailerLite Limited in Dublin and storage is documented in Germany and the Netherlands, with a long published subprocessor list and ISO 27001 certification. Against that, the second contracting entity is a Delaware corporation serving the rest of the world, the EU-hosting statement sits in FAQ and trust-page copy while the infrastructure is named as US-headquartered Google Cloud Platform, and US processors such as Intercom, OpenAI, Google Vertex AI and Stripe appear without a stated hosting region or legal basis for the transfer. 3 3 4

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 Integrator

The published tiers name subscriber ceilings, monthly email limits, seats and automation counts, the overage rule is an automatic upgrade to the next tier with the card charged, the free plan's lock at 250 active subscribers is spelled out, and billing counts only active subscribers. But the captured figures stop at "up to 500 subscribers", VAT treatment is only "All prices may be subject to applicable taxes", and the dedicated IP sits inside the unpriced custom tier, so a larger list has no visible number to compute an invoice from. 2 2 2

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 ⚠ unverified	—	uncited Report an error

Where this could be wrong

Evidence ages. The oldest capture behind this page is from 30 Aug 2026. Vendors change pricing and policies without notice; every fact reflects its source as of the capture date shown in the registry.
Weak sourcing — Legal entity, Data residency. Not confirmed on the vendor’s own pages as captured.
Weak sourcing — Subprocessors. Intercom is US-headquartered and the policy does not state its hosting region; the policy also names other US-based processors of product data (OpenAI, Google Vertex AI, Stripe for payments), while no subscriber Personal Data goes to Intercom unless the customer uploads it to the live chat.
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.
