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
More revenue from existing customers. Email marketing is based on real purchase data from weclapp. Cross-selling and upselling become measurable. Campaigns trigger automatically when customers become inactive or show potential. Customer lifetime value increases.
No more duplicate data maintenance. Customer data lives in weclapp, not in Excel files or in Inxmail. Changes are synchronized automatically. Marketing, sales, and accounting work with the same data. Fewer errors, less effort.
Better delivery rates for transactional emails. Send order confirmations and invoices via Inxmail Commerce instead of directly from weclapp. Inxmail is CSA-certified and delivers an average 98% delivery rate. Your customers receive the emails, you have tracking.
For: Marketing, Sales, Customer Success, Operations
Campaigns with real data instead of gut feeling. Who buys which product, who is inactive, who has potential: Everything is in weclapp. Inxmail fetches the data automatically. You build segments based on purchase history, revenue, and product interests.
Sales sees email engagement before the call. Open rates, clicks, and unsubscribes from Inxmail are displayed in the weclapp customer record. Sales knows whether the customer responds to mailings, which topics are of interest, when the last contact was.
Automated campaigns without manual export. No more CSV exports from weclapp and imports into Inxmail. The integration synchronizes in real-time. New customers automatically land in welcome campaigns. Inactive customers trigger retention mailings.
Make newsletter performance measurable. Inxmail delivers detailed tracking: who opens, who clicks, which links work. This data flows back to weclapp. Marketing can optimize campaigns, sales sees which topics resonate with the customer.
For: IT, Development, System Architects, Admins
Modern APIs, no legacy interfaces. weclapp offers a REST API with good documentation. Inxmail as well. Both systems support webhooks and event-based synchronization. The MARINI Integration Platform connects both systems bidirectionally.
Bidirectional synchronization without data loss. Customer data, purchase history, and segments flow from weclapp to Inxmail. Tracking data, unsubscribes, and opt-ins come back. Field mapping, validation, and duplicate detection are configurable. Conflicts are logged.
No installation in weclapp or Inxmail required. The integration runs via MARINI as middleware. Both systems are connected via their APIs. On-premises target systems can also be connected. You install nothing in the source systems.
Centralized monitoring, logs, and error handling. All data flows run through MARINI. You see in real-time what is being synchronized, where errors occur, which records cannot be mapped. Alerts for problems, logs for audits, rollback when needed.
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.
In weclapp, typically customers, contacts, articles, quotations, sales orders, invoices, and purchase history are retrieved.

Custom attributes in weclapp are supported and can be used for segmentation in Inxmail.

Yes, bidirectionally. When a recipient unsubscribes in Inxmail, the consent status is automatically updated in the weclapp customer record. Conversely, newsletter opt-ins from weclapp are adopted into Inxmail lists. This is GDPR-compliant and ensures that no unwanted mailings are sent.
weclapp is typically leading for customer master data, purchase history, orders, and invoices. Inxmail is leading for email sending, newsletter creation, tracking, and deliverability. The integration synchronizes bidirectionally, but you can define per data field which system holds the truth.
