Inxmail and rapidmail split the bench by criterion rather than by judge. Inxmail is ahead on integrations (6.8 to 4.0; six judges lean Inxmail), its verdict crediting self-service SOAP and REST APIs with public documentation plus named connections to Shopify, Magento, Shopware, OXID, Salesforce and Microsoft Dynamics. rapidmail is ahead on sovereignty (6.8 to 2.7; six lean rapidmail), consent and proof (5.0 to 3.5; six), campaign and automation (6.2 to 5.2; five lean, one tie) and pricing transparency (5.2 to 0.5; six — rapidmail shows prices at the 500-contact step, and Inxmail publishes no prices, noted as a B2B norm). The genuine splits are deliverability (4.0 vs 4.2; five ties, one lean to rapidmail) and list data control (5.7 vs 6.0; four ties, two leans to rapidmail). Weighted totals are on record for five judges; rapidmail scores higher in each, and we found no totals for the e-commerce owner.
Choose Inxmail if
You build your own connectors and need documented self-service APIs — six judges lean Inxmail on integrations (6.8 to 4.0), crediting public SOAP and REST documentation and a Commerce API for transactional workflows.
Your stack includes Shopify, Magento, Salesforce or Microsoft Dynamics — Inxmail documents named connections to these platforms; rapidmail's documented integration surface is Shopware 6 and Plentymarkets.
You send transactional email and need an SMTP mail relay module alongside newsletters — both are named modules in Inxmail's line-up.
You synchronise recipient responses, delivery information and subscription states into your own warehouse or CRM — Inxmail documents bidirectional export for this.
Choose rapidmail if
You need your provider contracted in Germany with servers in Germany — rapidmail's data processing agreement assures server location Germany, and sovereignty runs 6.8 to 2.7 with six judges leaning rapidmail.
Your security review requires an ISO 27001-certified datacenter and daily encrypted backups on German servers — rapidmail documents both.
Your compliance team limits subprocessor exposure to the EU — rapidmail's attribute is EU-only; Inxmail's is US Cloud Act.
You must export consent records together with your lists — rapidmail's CSV and Excel exports include the double opt-in record, and consent and proof runs 5.0 to 3.5 with six leans to rapidmail.
You want to see prices before talking to sales — rapidmail shows prices at the 500-contact step (pricing transparency 5.2 to 0.5, six leans), while Inxmail publishes no prices.

The Skeptic
Has seen every vendor claim 99% deliverability and GDPR compliance on the same page. Reads for the contact-tier staircase, the overage rate, the feature that begins two tiers up, and whether "EU hosting" covers the sending infrastructure or only the database.

This judge's pick
Criterion by criterion
Campaigns & automation
Inxmail
A drag-and-drop editor, an audience editor segmenting by language, location and purchasing behaviour, and a visual workflow builder with templates for common sequences are documented, plus a dynamic-content add-on for per-segment personalisation. We found no public information on A/B testing, send-time optimisation or holdout measurement, which is what separates this from a higher band.
rapidmail
A visual workflow with if/then branching, triggers on signup, recipient activity and date, unlimited mailings per automation, 250-plus templates and tagging are all documented — that clears the journey-builder bar, and per-tier automation counts are stated. We found no public information on subject-line or content A/B testing, send-time optimisation, dynamic content per segment or holdout measurement, which is what separates a competent automation tool from a complete one.
Deliverability infrastructure
Inxmail
Automatic bounce handling, a requirement that the spam rate stay below 0.3 percent, domain-authorisation protection and a deliverability team that diagnoses spam-folder causes are documented. But we found no public information naming SPF, DKIM or DMARC setup, custom sending domains, dedicated IPs or warm-up — authentication appears only as a generic word in the relay copy.
rapidmail
Real authentication documentation exists — DKIM for mailings and forms, SPF set up as a CNAME, and DMARC policies explained with a recommendation above 5,000 recipients — rather than only the advertised "höchste Zustellbarkeitswerte", plus account activation gated on a list-quality review. We found no public information on a stated bounce-suppression policy, complaint-loop handling, dedicated IP options or warm-up, and the vendor itself states it can only check whether a DNS entry exists, not whether it is correctly configured.
Consent, proof & tracking limits
Inxmail
Tracking can genuinely be left out — open and click tracking is listed as an optional service and the platform's tracking is described as optionally integrable — and double opt-in appears in the Shopware and Meta Lead Ads integration descriptions. We found no public information on the consent record itself, unsubscribe handling, a preference centre, or whether double opt-in is the default anywhere on the platform.
rapidmail
Double opt-in is documented as automatically applied, and the consent record is unusually deep — IP address, date and time for both the signup and the confirmation, exportable per contact — which is close to evidence-grade. The captured privacy policy describes a tracking pixel and tracking links in every mailing, and we found no public information on turning tracking off per campaign, on versioned and retrievable form wording, or on unsubscribe effect across lists.
List ownership, import & exit
Inxmail
Automated CSV import and a bi-directional export automation that pushes recipient responses and delivery information into a warehouse or campaign tool are documented, with a REST API carrying recipient data, content and statistics in real time. We found no public information on documented deletion across records, export of campaigns and templates, or exit terms.
rapidmail
Recipient lists export as CSV or Excel with a documented path and retrievable files, per-mailing opens, clicks, bounces and unsubscribes export from the statistics area, backups are restorable, and the API covers recipient management. We found no public information on exporting campaigns and templates, and contact deletion is asserted as GDPR-compliant deletion without a documented process or evidence of execution.
Integrations & API
Inxmail
SOAP and REST APIs with public documentation and self-service connection, a Commerce API that triggers events and returns transaction results, and named bidirectional integrations including Shopify, Magento, OXID, Salesforce and Microsoft Dynamics — with partner platforms claiming over 100 and over 300 systems respectively — make this surface broad. We found no public information on webhooks with retries, documented rate limits or a sandbox, which keeps it short of the top band.
rapidmail
Two named shop integrations — Shopware 6 and Plentymarkets via SOAP and REST — plus an API that sends mailings and manages recipients, with a developer documentation site. We found no public information on webhooks, documented rate limits, a sandbox, or any named CRM integration, so the connection surface reads as shop-only.
European sovereignty
Inxmail
The captured pages name the vendor as Inxmail GmbH with a named CEO, but we found no public information on where subscriber data is hosted, the contracting entity's jurisdiction, ownership, or any subprocessor list. Even the security and data-protection page as captured contributes nothing on hosting or subprocessors, so nothing evidences that sending and tracking stay in the EU.
rapidmail
The core is genuinely DACH: a German contracting entity in the commercial register, a German datacenter with ISO 27001, a data processing agreement available in the customer account that assures the server location Germany, and daily encrypted backups on German servers. The datacenter operator is not named and a complete subprocessor list is not published, and we found no public information on where the sending infrastructure or the authentication service partner Entri sit — the Google and HubSpot entries with standard contractual clauses concern the vendor's own website, not the sending chain.
Pricing transparency
Inxmail
No captured page shows a price of any kind — no contact tiers, no send limits, no overage rates, no VAT treatment; the commercial path is a demo request and a free test. The relay page lists included services but attaches no figures to them, so a sender cannot compute any invoice from the public pages.
rapidmail
Three tiers are priced at the 500-contact step — "Essential 15,00 € / Monat bis zu 500 Kontakte", "Performance 25,00 € / Monat", "Unlimited 35,00 € / Monat" — with the tier boundaries for automations, recipient lists, sender addresses and users stated, and a no-term "20,00 € / Gesamt" send of 500 emails. The captured pages show prices only at that bottom rung, and we found no public information on higher contact tiers, send limits below Unlimited, overage rates or VAT treatment.
