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.

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.

Report an error

The Deliverability Engineer

The captured pages document a drag-and-drop editor with segmentation by engagement, geography, interests, purchase history and signup source, plus multi-step automations with per-tier limits and a webhook action usable inside workflows. I found no public information on subject-line A/B testing for campaigns or a journey builder that branches on behaviour, so this sits solidly mid-table rather than higher. 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 Deliverability Engineer

Authentication is documented end to end — DKIM, SPF and domain verification records with an automated DNS setup path — and bounce discipline is real: hard bounces auto-suppressed, three consecutive soft bounces treated as hard, and a list-verification tool recommended. I found no public information on DMARC guidance, on warm-up for the dedicated IP that appears in the enterprise tier, or on inbox-placement testing, so the documented stack stops short of the top. 2 7 8

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 arrives with field mapping, duplicate cleanup, banned-address screening and a direct Mailchimp path, and export covers custom fields, group membership, unsubscribed and bounced status, campaign opens and clicks, and automation activity, with deletion promised within 30 days of an eligible request. Campaigns and templates are not shown as exportable and the export function is administrator-only, so exit is workable but not a documented feature. 3 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

Shopify, WooCommerce, WordPress, Zapier and Canva are named among a claimed hundred-plus integrations, webhooks cover fifteen subscriber and campaign events with three retries, HMAC signatures and full create-read-update-delete management, and there is a batch endpoint plus an MCP server. I found no public information on a sandbox or on concrete rate-limit numbers beyond the batch cap, and transactional sending requires a separate MailerSend account rather than one API. 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 Deliverability Engineer

Hosting is documented in Germany and the Netherlands with a named infrastructure provider, an Irish contracting entity covers EEA, UK and Swiss billing addresses, and a long subprocessor list is published. A second Delaware entity with Data Privacy Framework certification and FTC authority serves everyone else, US-headquartered processors — Intercom for support, OpenAI and Google Vertex AI for AI features, Stripe for payments — appear with hosting regions unstated, and the EU-only hosting claim sits in FAQ and trust-page copy rather than contract text. 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 Deliverability Engineer

Entry prices are public with billing period and currency — $0 for up to 250 subscribers, $12 listed and $10.80 per month billed yearly for the entry paid tier, $25 and $22.50 for the next — send limits are stated per tier, and overage behaviour is spelled out as an automatic upgrade and charge. The enterprise tier carrying the dedicated IP shows no captured price, taxes are covered only as "may be subject to applicable taxes", and I found no public information on tier prices beyond the 500-subscriber entry point. 2 2 2
