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.
Read this comparison as one judge. Each weighs the same scores by what they care about.
The Deliverability Engineer
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.

This judge's pick
Criterion by criterion
Campaigns & automation
Inxmail
A visual drag-and-drop workflow editor with templates for common sequences, segmentation on attributes and purchasing behaviour, and dynamic personalized content as an add-on; event triggers arrive from other systems through the Commerce API. We found no public information on A/B testing, send-time optimisation, or holdout measurement.
rapidmail
There is a visual workflow builder with drag-and-drop editing, if/then branching, triggers on signup, recipient activity and date, unlimited steps per automation, free test sends before activation, and documented use-case templates. We found no public information on subject-line A/B testing, send-time optimisation or holdout groups, which keeps this short of the top band.
Deliverability infrastructure
Inxmail
Bounce management is documented as automatic handling and tracking of delivery errors, protective mechanisms hold the spam rate below 0.3 percent, and a deliverability team is named as included — but authentication is asserted in one word rather than documented as SPF, DKIM or DMARC setup, and we found no public information on dedicated IPs, warm-up, or engagement-based sunsetting. The "high delivery rate" line on the sending servers is a number I discount on principle.
rapidmail
Authentication is documented properly: SPF via CNAME, DKIM for mailings and signup forms, and DMARC with policy guidance plus a status display and realistic verification timing — this is setup documentation, not a delivery-rate boast, so I count it. Beyond a list-quality review before accounts are activated and exportable bounce records, we found no public information on automatic hard-bounce suppression, complaint-loop handling, dedicated IP options with warm-up, or inbox-placement testing.
Consent, proof & tracking limits
Inxmail
Tracking and reporting are optional rather than built in — open and click tracking is listed as an optional service — and consents are handled as data that syncs to your leading system. Double opt-in appears only inside two integration descriptions rather than as a documented default, and we found no public information on what the consent record stores, unsubscribe handling, or retention rules for inactive subscribers.
rapidmail
Double opt-in is applied automatically, the duty-of-proof requirement is addressed, and the consent record exports with IP address, date and time for both signup and confirmation — that is a usable evidence trail. Against that, the privacy policy describes a tracking pixel and tracking links in every mailing, and we found no public information on a mode to switch tracking off, on versioned consent wording, or on documented access and erasure-request handling.
List ownership, import & exit
Inxmail
Export automation is bidirectional and pushes recipient responses, delivery information, subscriptions, unsubscriptions and consents into your own campaign management tool or warehouse in real time, so engagement history clearly leaves the platform. We found no public information on documented deletion of a subscriber across all records, on export formats and throttling, or on full-fidelity export of the whole account.
rapidmail
Recipient lists export as CSV or Excel including the opt-in record, per-recipient activity — opens, clicks, bounces and unsubscribes — is exportable per mailing, an API manages recipients for syncing elsewhere, and list backups can be restored. We found no public information on exporting campaigns or templates, on import with attributes intact, or on deletion that is evidenced rather than stated as GDPR-compliant.
Integrations & API
Inxmail
Self-service SOAP and REST APIs with available documentation, transactional sending and event triggers through the Commerce API, and dozens of maintained integrations including Shopify, Magento, Shopware, Salesforce and Microsoft Dynamics, plus wider reach through com:con BAF and Marini. We found no public information on webhooks with retry behaviour, documented rate limits, or a sandbox.
rapidmail
There is a publicly documented API with a developer site that can send mailings and manage recipients — a write-capable surface, not a read-only one — plus native Plentymarkets and Shopware 6 connections. We found no public information on webhooks, documented rate limits, a sandbox, or CRM integrations beyond the two shop platforms.
European sovereignty
Inxmail
The captured pages name Inxmail GmbH, but we found no public information on where subscriber data and behavioural tracking are hosted, on the contracting entity's jurisdiction, or on a single subprocessor that touches the send. For a buyer who weighs this heavily, undocumented equals unevaluable — even the captured security and privacy pages yielded nothing on residency.
rapidmail
The contracting entity is a German GmbH in Freiburg, hosting is in a German datacentre assured by the data-processing agreement and backed by an ISO 27001 certificate, backups are daily, encrypted and stored in Germany, and an external German data-protection officer is named. The data-centre operator itself is not named, a complete subprocessor list is not published, and the vendor's own website runs Google and HubSpot under standard contractual clauses — non-EU processing named with a legal basis, but not a fully evidenced chain.
Pricing transparency
Inxmail
No price figure appears anywhere: the captured pages offer a free test and a live demo, and enumerate what the relay includes — hosting and administration costs, one hour of user support per month, deliverability team assistance — with open and click tracking as an optional service. We found no public information on contact tier prices, send limits, or overage rates.
rapidmail
Three tiers are priced publicly at up to 500 contacts with the monthly period stated, per-tier limits on automations, lists, sender addresses and users are spelled out, and a pay-as-you-go option of 1 x 500 emails for a total of 20,00 € with no contract term is listed. We found no public information on overage rates, VAT treatment, or prices for contact volumes beyond 500, so the invoice for a bigger list is not computable from these pages alone.
