Inxmail

Inxmail is a Freiburg-headquartered German email marketing platform operated by Inxmail GmbH (Wentzingerstr. 17, 79106 Freiburg im Breisgau), founded in 1999 and one of the longest-running independent ESPs in DACH. The product is positioned as a premium enterprise solution for media and publishing, energy utilities, banking and insurance, and retail/e-commerce, with a modular platform covering newsletter campaigns, marketing automation, transactional / trigger-based emails, and an SMTP Mail Relay. Inxmail reports more than 2,000 corporate customers. The compliance posture is strong on the technical side: customer data is hosted exclusively on EU servers, the company is ISO 27001-certified by TÜV Rheinland (first issued 2020) for development and operation of its email marketing applications, and it carries the "Software Made in Germany" industry seal. The privacy policy notes that any transatlantic transfers (e.g. for Google Analytics or LinkedIn marketing pixels on the corporate website) are covered by Standard Contractual Clauses; the external Data Protection Officer is DDSK GmbH. Where Inxmail is weaker for a procurement-grade scoring is transparency: the dedicated DPA (AVV), security, and sub-processor pages were not publicly resolvable at audit time, and pricing is enterprise-only on a sales-contact basis, so small EU buyers cannot self-serve a copy of the DPA — which is precisely the cap-at-3/5 rule in our compliance rubric. Pricing is custom: per the public prices page, fees cover hosting, administration, deliverability team, and monthly user support, scaling with email volume; no public price tier or freemium is advertised. Best fit: mid-market and enterprise marketers in DACH (publishers, utilities, financial services) who want a long-running independent German vendor, ISO 27001 attestation, and white-glove deliverability support, and are comfortable with sales-mediated procurement. Buyers who need a freemium entry tier or self-serve DPA download should look at CleverReach or rapidmail in this category.
