SAP C4C is SAP’s CRM system for sales and service with native SAP integration, while Inxmail is one of the leading email marketing specialists in German-speaking regions. Both systems offer extensive functionality but often operate in isolation from each other.
The SAP C4C Inxmail Integration connects CRM data with highly personalized email campaigns and bridges the gap between marketing and sales. Leads, contacts, and campaign performance flow bidirectionally in real-time, without manual exports or CSV files.
The integration enables sales and marketing to work from a unified data foundation. Here are typical scenarios:
Automatically use CRM contacts for newsletter campaigns. Accounts and contacts from SAP C4C are synchronized as recipients in Inxmail lists. Marketing works with current customer data without manually maintaining lists or risking data duplicates.
Make email engagement visible in the CRM. Opens, clicks, bounces, and unsubscribes from Inxmail are displayed directly in the SAP C4C contact record. Sales knows before the call whether a contact opened the last campaign or which topics interest them.
Automatically create leads from campaigns in the CRM. Qualified leads from Inxmail forms or campaigns are immediately created as leads in SAP C4C and assigned to the responsible sales representative. No more manual handoffs, no lost inquiries.
Personalize campaigns with CRM data. Opportunity status, account data, industry, or custom fields from SAP C4C control segmentation in Inxmail. Marketing can deploy campaigns based on real sales data instead of assumptions.
Synchronize opt-in and opt-out bidirectionally. Consent status and unsubscribes from Inxmail are transferred to the CRM, conversely changes from SAP C4C flow back. GDPR-compliant, without media breaks.
Link transactional emails with CRM events. Through Inxmail Commerce, event-based emails can be automatically sent when an opportunity status changes in SAP C4C or a ticket is closed. Relevant communication at the right time, triggered by CRM events.
The use cases on this page are not theoretical, but implementing them requires experience. You can set up integration and data management yourself through MARINI’s no-code interface, or have our team configure it for you. For implementation in your systems, we work collaboratively with you and your service providers. If you don’t yet have a suitable service provider, we’re happy to recommend an appropriate partner from our network.

CEO at Inxmail
Successful email marketing thrives on interesting and relevant, recipient-specific content. This requires the right content and current data from various sources such as CRM, shop systems, or other platforms. Creating relevant content from data for highly individualized emails is Inxmail’s strength. MARINI provides the necessary data for this, and that’s exactly why the combination of both systems leads to increased revenue and success.
For: C-Level, Management, Business Development
Marketing and sales work with the same data. When both departments access different data sources, friction, misunderstandings, and lost opportunities arise. The SAP C4C Inxmail Integration creates a common data foundation and measurably improves collaboration.
Faster response times bring higher conversion. Whoever responds first to an inquiry has a significantly higher closing probability. Qualified leads from Inxmail campaigns land in the CRM in real-time and are processed immediately, instead of disappearing in email inboxes.
Data-driven marketing becomes standard. Marketing can segment, personalize, and measure based on real sales data. This increases campaign relevance, reduces unsubscribe rates, and boosts the ROI of email marketing activities.
For: Marketing, Sales, Customer Success, Operations
No more CSV exports and manual list maintenance. Marketing works with current CRM contacts without manually exporting, cleaning, or reconciling lists. Changes in the CRM flow automatically to Inxmail, new contacts are immediately available for campaigns.
Sales sees who responds to which content. Opens, clicks, and downloads are visible directly in the contact record. Field sales knows before the appointment which topics interest the customer and can prepare the conversation accordingly.
Campaign attribution becomes transparent. Which email campaign contributed to which opportunity? The integration makes it possible to prove marketing’s contribution to revenue and allocate budgets accordingly.
Unsubscribes reach all systems. When someone unsubscribes from the newsletter, the opt-out status is transferred to the CRM. Conversely, changes from SAP C4C flow back to Inxmail. This keeps communication GDPR-compliant without anyone having to manually maintain records.

Bidirectional synchronization via REST APIs. SAP C4C offers OData REST APIs for accounts, contacts, leads, opportunities, and custom business objects. Inxmail Professional provides REST APIs for recipients, lists, mailings, and tracking data. MARINI orchestrates the bidirectional data flow in real-time without requiring you to write code.
Mapping and field rules without development effort. You define which fields from SAP C4C flow into which Inxmail fields and vice versa. You configure transformations, validations, and conditions via the no-code interface. New fields are automatically detected and can be integrated via dialog.
Event-based triggers for real-time synchronization. SAP C4C offers notifications (webhooks), Inxmail works with API-based events. MARINI uses both mechanisms to synchronize changes immediately. When a lead is created in SAP C4C, it flows to Inxmail without delay. When someone clicks a link, the tracking event appears in the CRM.
Custom business objects are fully supported. SAP C4C allows custom modules and entities that can be synchronized like standard objects. If you use custom fields or objects, MARINI integrates them just as seamlessly as standard data. Inxmail-specific fields can also be flexibly mapped.
Business-critical data deserves maximum reliability. At MARINI, security isn’t an add-on—it’s our lived standard. Our security architecture at a glance:
This keeps your central data infrastructure stable, protected, and scalable at all times. Together, we’ll find the right integration and tailor it precisely to your requirements.

MARINI already has an adapter for Inxmail Professional (newsletter, bulk emails). For Inxmail Commerce (transactional emails) and Inxmail New Xperience (web-based editor), adapters can be easily developed. All API endpoints are fully integrable, both uni- and bidirectionally. MARINI is an official integration partner of Inxmail.
With MARNI, we were able to successfully optimize our digital sales processes. We were particularly impressed by the flexibility and scalability of the platform, which helped us to implement our projects quickly and efficiently.
