The computed means split by criterion. Mailchimp is ahead on integrations (7.7 vs 4.0; 300+ integrations including a stated two-way Salesforce sync, against rapidmail's Shopware 6 and Plentymarkets), deliverability (6.8 vs 4.2), list data control (7.0 vs 6.0), campaign and automation (7.0 vs 6.2), and pricing transparency (5.3 vs 5.2; five judges tie, one leans Mailchimp). rapidmail is ahead on sovereignty, 6.8 to 1.5, with six judges leaning rapidmail and zero leaning Mailchimp: German contracting entity, a data processing agreement assuring server location Germany, EU-only data residency and EU-only subprocessor exposure, against Mailchimp's US jurisdiction, foreign-controlled ownership, US-default hosting and US Cloud Act exposure. Consent and proof is the genuine split (5.5 vs 5.0): four judges lean Mailchimp, one rapidmail, one tie. Mailchimp is ahead for the CRM manager, deliverability engineer, integrator and skeptic; rapidmail for the data protection officer. No overall winner: the lean differs by judge and criterion.
Choose Mailchimp if
Your team builds journeys with conditional and percentage splits — campaign and automation stands at 7.0 vs 6.2, with five judges leaning Mailchimp and one tie.
Your stack depends on two-way Salesforce sync or the stated 300+ integrations — integrations run 7.7 vs 4.0 with six judges leaning Mailchimp, against rapidmail's documented Shopware 6 and Plentymarkets.
Deliverability is your priority — six judges lean Mailchimp, 6.8 vs 4.2, and we found no public information on rapidmail's bounce suppression, complaint loops, dedicated IP or warm-up.
You need whole-account data portability — list data control is 7.0 vs 6.0 with six judges leaning Mailchimp, and Mailchimp documents a whole-account export as a zip.
Your compliance posture accepts a US contracting entity (The Rocket Science Group LLC under Intuit Inc.), US-default hosting and US Cloud Act subprocessor exposure, with transfers resting on annual Data Privacy Framework certification and standard contractual clauses as fallback.
Choose rapidmail if
You need EU-only data residency and EU-only subprocessor exposure — rapidmail's sovereignty attributes state both, and sovereignty runs 6.8 vs 1.5 with six judges leaning rapidmail and zero leaning Mailchimp.
Your contract must sit with a German entity — rapidmail is the newsletter tool of Positive Group Deutschland GmbH in Freiburg, and its data processing agreement assures server location Germany.
Your data protection officer holds the deciding voice — their weighted total reads 6.0 for rapidmail against 4.6 for Mailchimp.
Your security review requires an ISO 27001-certified datacenter and daily encrypted backups on German servers — both are documented for rapidmail.
You need the consent record to travel with your list exports — rapidmail's recipient lists export as CSV or Excel with the double opt-in record included, and its list data control score sits at 6 with no spread.
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.

Criterion by criterion
Campaigns & automation
Mailchimp
Automation flows are documented as a visual journey map with conditional and percentage splits, wait steps, webhooks and up to three segmentable triggers, plus dynamic content on paid tiers and an API trigger that starts journeys from outside events. We found no public information on send-time optimisation, holdout groups, or A/B testing that reports significance, which keeps a genuinely strong journey builder short of the top band; flow depth is also tier-gated to four steps on the entry paid plan.
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
Mailchimp
Authentication is documented properly — domain verification first, then two CNAME records for DKIM and one TXT for DMARC, with an automated setup method and guidance on the Gmail and Yahoo DMARC requirements — and bounces are categorised soft or hard from SMTP replies with subscriber engagement factored into cleaning decisions. Dedicated IPs are provisioned with a roughly 30-day warm-up and custom reverse DNS on the transactional side. We found no public information on inbox-placement or seed testing, complaint-loop handling, or sunsetting of inactive subscribers, so the top of this band stays out of reach.
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
Mailchimp
Double opt-in exists per audience with a customisable confirmation mail, the captured pages show a plain-text record of the GDPR form wording stored on each contact profile, and exports carry SMS consent source and revocation times — consent evidence a long way past a bare timestamp, with a forget endpoint and per-audience contact export behind it. But double opt-in is offered as one of two opt-in methods rather than a documented default and can be enabled only on Mailchimp signup forms, and we found no public information on switching open or click tracking off, pixel-free sending, or unsubscribe honoured across audiences.
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
Mailchimp
Exit is documented as a real feature: a whole-account zip with audiences, campaign content, templates, gallery assets, contact events and reporting data, plus per-contact CSVs that include opens, clicks and campaign interactions, and API actions that delete all personally identifiable information or forget a contact. The captured pages also state only one export can be generated per 24 hours and that contact-level exports must be repeated per audience when a contact sits in several, and the migration services we can see run inbound only, for Premium customers or the first 30 days of an 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
Mailchimp
Over 300 integrations included in every plan, named two-way sync with Salesforce and a Shopify connection, and two documented APIs — marketing (version 3.0.91, batch operations, list webhooks) and transactional (raw MIME sending, scheduled mail, SMS, subaccounts, inbound routes, tracking domains). Per-endpoint rate limits are stated and deprecation is practised openly, with the legacy export API given an end date; we found no public information on a sandbox or documented webhook retries.
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
Mailchimp
Sovereign this is not: the contracting entity is The Rocket Science Group LLC under Intuit Inc. in Mountain View, US storage is the fixed default with no EU hosting option on any captured page, and even export files are hosted by Google. Transfers do carry a stated basis — annual EU-US Data Privacy Framework certification with SCCs folded into the data processing addendum as fallback — and some processors are named, but we found no public information confirming a complete subprocessor list, and session replay runs through FullStory and Medallia.
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
Mailchimp
Monthly prices are public with send limits per plan, automation flow depth per tier, and feature boundaries down to audiences, seats and onboarding sessions — enough to price the shape of a plan before talking to anyone. But overage is only ever stated as extra costs applying when limits are exceeded, we found no public information on VAT treatment or a Premium price figure, and the captured pages give different figures for the same plans — Standard at €17.45/Monat and at €17.68/Monat, Essentials at €11.34/Monat and at €11.50/Monat — which we do not choose between.
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.
