Mailchimp leads five criteria: campaign and automation (7.0 versus 6.0; six judges lean Mailchimp), deliverability (6.8 versus 6.3; four lean Mailchimp), list data control (7.0 versus 3.8; six lean Mailchimp), integrations (7.7 versus 6.7; five lean Mailchimp) and pricing transparency (5.3 versus 4.3; five lean Mailchimp). The list-data gap has a stated reason: CleverReach's verdict found no public information on a whole-account exit, while Mailchimp documents a whole-account export as a zip. CleverReach takes the other two — consent and proof (6.5 versus 5.5; three lean CleverReach, three tie) and sovereignty (5.3 versus 1.5; six lean CleverReach), where Mailchimp's captured pages show US hosting as the fixed default. The benches also split by judge: five weighted totals are published, four favor Mailchimp, and the data protection officer persona favors CleverReach, 5.5 to 4.6. That split, not a single winner, is the result.
Choose CleverReach if
You must be able to evidence consent in a dispute: CleverReach's double opt-in logs automatically, and consent and proof leans CleverReach three judges to zero with three ties (6.5 versus 5.5).
Your compliance team requires EU data residency: CleverReach's sovereignty attribute lists EU-only data residency, and six judges lean CleverReach on sovereignty (5.3 versus 1.5) — though its verdict notes support data is hosted in the USA via Zendesk on the basis of consent.
Your procurement requires a German contracting entity: CleverReach's legal entity jurisdiction is DE.
Your data protection officer signs off on the purchase: that persona's weighted total favors CleverReach, 5.5 to 4.6.
Choose Mailchimp if
You need to leave with your data intact: Mailchimp documents a whole-account export as a zip, and six judges lean Mailchimp on list data control (7.0 versus 3.8).
Your team builds journeys with conditional and percentage splits: six judges lean Mailchimp on campaign and automation (7.0 versus 6.0).
You rely on 300+ integrations, including a stated two-way Salesforce sync: five judges lean Mailchimp on integrations (7.7 versus 6.7).
Deliverability comes first for you: four judges lean Mailchimp on deliverability (6.8 versus 6.3).
You need published pricing figures and US-default hosting is acceptable to your compliance team: five judges lean Mailchimp on pricing transparency (5.3 versus 4.3), and Mailchimp's data residency attribute reads US by default.
Read this comparison as one judge. Each weighs the same scores by what they care about.
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.

Criterion by criterion
Campaigns & automation
CleverReach
A visual drag-and-drop automation editor, behaviour and tag triggers, twenty-plus prebuilt automation tracks, cart-abandonment and RSS mailings, and subject-line A/B testing with automatic winner send clear the middle of this criterion comfortably. What holds it back is that the A/B analysis reports raw open rates, and we found no public information on branching journeys on behaviour and data, send-time optimisation, or testing that reports significance.
Mailchimp
The flow builder is the real thing — conditional and percentage splits, wait-for-trigger, webhooks and API-triggered entry, dynamic content from Standard up — but flow depth itself is metered by plan (200 flow points on Standard versus 4 steps per flow below). We found no public information on A/B testing, send-time optimisation or holdout groups.
Deliverability infrastructure
CleverReach
DKIM is documented in unusual depth and made a precondition for sending, with automatic DNS record generation and a record check, and bounce handling is refreshingly concrete: soft bounces blocked a month with up to three retries, hard bounces a year, plus a deliverability dashboard in the reporting. We found no public information on DMARC setup guidance, complaint-loop handling, dedicated-IP warm-up or seed testing — the advertised 90% inbox rate is a third-party benchmark, and the dedicated IP appears only as an on-request item in the Enterprise tier.
Mailchimp
Authentication is documented down to the DNS records — two CNAMEs for DKIM, one TXT for DMARC, with an automated setup path — plus dedicated IPs with a roughly 30-day warm-up and automatic soft/hard bounce categorisation that factors engagement into cleaning. We found no public information on complaint-loop handling or seed and inbox-placement testing, and bounce reasons expire after 30 days with no bulk export.
Consent, proof & tracking limits
CleverReach
Double opt-in is the documented standard for signup forms, its confirmation is automatically logged so the sender can prove consent in a dispute, and unsubscribe is immediate with single, confirmed and double opt-out variants, a reason field and full documentation. We found no public information on whether the stored consent record captures the form wording or source, on a per-campaign tracking switch (only a global option to anonymise reporting data is documented), or on handling of access and erasure requests, so this stops short of consent reproducible as evidence.
Mailchimp
Double opt-in exists per audience but only for Mailchimp signup forms — contacts added via API cannot get it — and single opt-in is offered equally, so it is a choice rather than a default. The versioned form wording retrievable on each contact's profile is genuinely proof-grade consent evidence; we found no public information on switching open and click tracking off, or on unsubscribe honoured across audiences.
List ownership, import & exit
CleverReach
Import is well served — CSV, Excel, text files and FTP with 45 custom fields, real-time sync from shop, CMS and CRM, a developer API and webhooks — and deletion is documented both per record ("Datensätze jederzeit bearbeiten oder löschen") and at account level within 10 days of withdrawal. We found no public information on subscriber export, engagement-history export, or any migration or exit tooling, so a buyer cannot see from the captured pages how their list and its history leave the tool.
Mailchimp
Exit is materially supported: an account export as a zip with audiences, campaign and template content, contact events and reporting, opens and clicks files per contact, and documented permanent deletion endpoints. What caps it is the metering — one export per 24 hours, per-audience exports for access requests, and files hosted by Google behind signed URLs that skip user verification.
Integrations & API
CleverReach
More than 120 integrations with named systems across Shopify, Shopware, WooCommerce, HubSpot and Salesforce, real-time recipient sync, a documented developer API with a PHP SDK and an MCP server, and webhooks delivering POST requests with verification and optional encryption. We found no public information on rate limits, webhook retries or a sandbox, which is where this surface stops short of the top band.
Mailchimp
Named integrations for the shops and CRMs that matter — Shopify, Square, Lightspeed, a two-way Salesforce sync — across 300+ apps, with marketing and transactional APIs, webhooks in both directions and batch operations. We found no public information on a sandbox or webhook retries, and rate limits appear only for a single search method at 20 calls per minute.
European sovereignty
CleverReach
The German contracting entity is verifiable down to the commercial register and VAT ID, there is an external data protection officer in Hamburg, a digitally signable data processing agreement, and the claim that all data sits exclusively on servers in Germany and the EU in ISO 27001-certified data centres. But the data-centre provider goes unnamed, we found no public information on where the sending infrastructure runs or on a complete subprocessor list for the service itself, and the captured pages give different pictures of third-country processing: the GDPR page states servers in Germany and the EU with no processing in an unsafe third country, while the privacy policy names support data hosted exclusively in the USA on the basis of consent.
Mailchimp
US contracting entity under Intuit, US hosting with no EU option anywhere on the captured pages, and no published subprocessor list — names like Twilio, FullStory, Medallia and Google appear only incidentally in the privacy statement. Transfers do carry a stated basis (annual DPF certification with SCCs as contractual fallback), which is more than nothing, but the entire structure rests on the framework this buyer does not trust, and this category weighs it heavily.
Pricing transparency
CleverReach
The free tier is concrete (250 recipients, 1,000 mails a month, permanent, no credit card) and the add-ons carry real numbers — 22,95 € im Monat premium support, 5,00 € per design-and-spam test, 3,00 € per accessibility test — with billing annual in advance and a stated 10% annual discount. But of the paid tiers only Enterprise shows a figure on the captured pricing page (449,10 $ per month); we found no public information on what the Basic or Pro tiers cost, on VAT treatment, on a price for the dedicated IP offered on request, or on where automation begins below the Pro tier, which lists unlimited automations.
Mailchimp
Headline monthly prices and per-tier send limits are public — Standard with 6,000 emails per month, the captured pages giving different figures for Essentials (€11.34 versus €11.50 per month) and Standard (€17.45 versus €17.68 per month) — with feature gating laid out per tier. Overage rates, VAT treatment and the price of the SMS add-on, dedicated IPs and high-volume plans are not stated, and the captured pages describe exceeding the limit both as incurring extra costs and as paused sending.
