Latest Updates
View all releases- Pixel — Double Page View Counting (WordPress Plugin):
- Removed netsendo_wp_track_page_view() function and its wp_footer hook from the WordPress plugin. The NetSendo Pixel JavaScript already tracks page views automatically on initialization — the redundant PHP hook was causing every visit to be counted twice.
- Pixel — Engagement Events Misreported as Page Views:
- Fixed trackTimeOnPage() sending page_view event type instead of a dedicated engagement event. This was further inflating page view counts with time-on-page/scroll-depth data. Renamed to trackEngagement() and changed event type to engagement.
- Autoresponder Queue — Missing SubscriberSignedUp Events:
- Fixed autoresponder messages not being queued for subscribers added to lists through automations, tracked link clicks, webinar registration, subscriber preferences, CardIntel, form co-registration, resubscribe links, and CSV import. Root cause: these 10 code paths added subscribers to lists without dispatching the SubscriberSignedUp event, which is the sole trigger forCreateAutoresponderQueueEntries listener. All paths now correctly dispatch the event with unique source labels for traceability.
- Brain — Full Automation Management (SegmentationAgent):
- 5 New Executors: create_automation (creates AutomationRule with trigger, actions, conditions, rate limiting), update_automation (modifies any fields), toggle_automation (enable/disable), delete_automation (with system rule protection), list_automations (full list with stats and execution counts).
- Enriched AI Context: Plan prompt now includes all 30+ available trigger events, 18 action types, 15+ condition types, and the user's existing automations — enabling AI to make informed automation decisions.
- Validation: Trigger event validation, empty actions check, system rule deletion protection.
- Brain — A/B Test Management (CampaignAgent):
- 3 New Executors: create_ab_test (creates AbTest + AbTestVariant records with type, sample %, auto-winner, up to 5 variants), check_ab_results (displays per-variant open rate, click rate, CTOR with winner determination), list_ab_tests (lists all tests with status, type, metric, and winner).
- Marketplace — Perplexity AI Integration Page:
- New dedicated marketplace page (/marketplace/perplexity) with hero section, features overview (deep research, company intelligence, trend analysis, content ideas), setup guide, use cases, and sidebar with resources.
- Added Perplexity AI to marketplace active integrations grid and AI & Research category.
- Full translations in PL, EN, DE, ES.
- Marketplace — SerpAPI Integration Page:
- New dedicated marketplace page (/marketplace/serpapi) with hero section, features overview (Google Search, news search, knowledge graph, company lookup), setup guide, supported search types, use cases, and sidebar with resources.
