We've just released Octeth v5.7.2, combining nearly 800 commits of improvements developed over the past 8+ months. This release represents two major milestones - v5.7.0 (released November 16, 2025) and v5.7.2 (released December 29, 2025) - and includes some of the most significant enhancements we've ever shipped.
Here's what's new.
Journey Builder Complete Redesign
The centerpiece of this release is a complete overhaul of our Journey Builder. We didn't just add features - we rebuilt the entire system from the ground up.
Decision Nodes with Advanced Logic
Journey decision nodes now support sophisticated conditional branching with nested decision structures. You can build complex workflows that adapt to subscriber behavior in real-time, routing contacts through different paths based on their actions, field values, or engagement patterns.
Multiple Journey Triggers
Journeys can now be triggered by multiple events simultaneously:
- Email opens
- Email link clicks
- Custom field value changes
- Journey completions
- Tag assignments and removals
- Multiple tags at once (v5.7.2)
The multi-tag trigger capability is particularly powerful - you can now trigger journeys only when subscribers have multiple specific tags, enabling sophisticated segmentation-based automation.
Multiple Enrollments
Contacts can now enroll in the same journey multiple times. This opens up recurring campaign scenarios, seasonal promotions, and behavioral workflows that were previously difficult to implement.
Journey Statistics Dashboard
We've added a comprehensive analytics screen that gives you deep visibility into journey performance. Track execution rates, conversion paths, bottlenecks, and outcomes - all with 95% less database load than before.
The drag-and-drop interface has been refined with better node cloning, improved visual feedback, and smoother interactions throughout.
Google Postmaster Tools Integration
Email deliverability has always been about data - knowing what inbox providers see when they receive your emails. We've integrated Google Postmaster Tools directly into Octeth to give you that visibility.
Complete OAuth Integration
Connect your Google Postmaster account through a secure OAuth flow. Once connected, Octeth automatically collects and monitors your sending reputation data.
Analytics Dashboard
The new analytics dashboard shows correlation analysis between your sending patterns and deliverability metrics, encryption rates, spam classification trends, and detailed performance breakdowns by domain and IP.
Automated Monitoring
Data collection runs automatically in the background. Redis caching ensures the dashboard loads instantly while keeping your reputation data up-to-date.
This integration gives you the same deliverability insights that major ESPs use internally - now available in your self-hosted Octeth instance.
Admin Campaign Report Page
v5.7.2 introduces a powerful new admin interface for campaign analytics.
The report page includes advanced filtering capabilities that let you slice campaign data by date range, status, user, or delivery performance. Real-time velocity metrics show how fast campaigns are sending and where bottlenecks might be occurring.
Batch statistics give you visibility into sending patterns at a granular level - useful for troubleshooting delivery issues or optimizing throughput.
Performance Optimizations Throughout
Beyond the headline features, we've made substantial performance improvements:
- Redis caching now covers entities, custom fields, lists, and counts
- Journey statistics queries reduced database load by 95%
- Campaign monitoring APIs optimized with auto-interval velocity calculations
- Query optimizations across subscriber searches, segment filtering, and list operations
These aren't just theoretical improvements - they translate to faster page loads, more responsive interfaces, and the ability to handle larger contact databases without performance degradation.
Security Enhancements
We've addressed several security issues including SQL injection vulnerabilities in order parameter validation, XSS prevention in admin interfaces, and improved authentication token management. All Octeth users should upgrade to this release.
API Improvements
The API surface has expanded with new endpoints for subscriber tagging, journey bulk operations, and segment retrieval optimization. We've also standardized error codes across all API responses and added comprehensive validation to prevent invalid requests.
What This Means for You
If you're running Octeth, this release gives you capabilities that most commercial email platforms charge premium prices for - journey automation with sophisticated logic, deliverability monitoring integrated with Google, and enterprise-grade analytics.
For those evaluating Octeth, this release demonstrates our commitment to continuous improvement. We're not standing still - we're actively building features that solve real email marketing challenges.
