NetSendo v1.7.12: Claude 4.5 AI & Key Fixes
🚀 A Smarter, More Stable NetSendo: Introducing v1.7.12
In the world of marketing automation, reliability isn't just a feature—it's the foundation. Every link must track, every feature must work seamlessly, and the platform must be secure. That's why we're excited to release NetSendo v1.7.12, a significant update focused on stability, bug fixes, and a major upgrade to our AI integration capabilities.
This release addresses key user-reported issues, making your daily workflows smoother while also future-proofing your content strategy with the latest generation of AI models from Anthropic, OpenAI, and more. It's all about providing a robust, self-hosted platform you can truly depend on.
🔧 What's New and Improved in v1.7.12
This update is packed with refinements that enhance the core NetSendo experience. Let's dive into the details.
🤖 A Major AI Upgrade: Meet the January 2026 Models
Staying on the cutting edge of AI is crucial for creating compelling content. We've updated our AI provider integrations with the latest models available as of January 2026.
Anthropic Claude 4.5
The entire Claude 4.5 family is now available, from the lightning-fast Haiku to the powerhouse Opus 4.5, giving you the perfect balance of speed and intelligence.
Next-Gen OpenAI & Google
Access GPT-5.2 Preview models via OpenRouter and the powerful Gemini 2.5 Pro from Google, ensuring you always have the best tool for the job.
Enhanced Connection Testing
We've fixed the Anthropic connection test, which now uses your selected model for validation and provides clearer error messages (401 vs. 404) for easier debugging.
ℹ️ Note: The new default model for Anthropic is now claude-sonnet-4-5-20250929, offering a fantastic blend of performance and advanced reasoning for your marketing copy.
🔗 Smarter, More Reliable Link Tracking
Have you ever had a tracked link with a URL hash (like #section) fail to trigger a list action? This was caused by a subtle mismatch in how URLs were encoded. We've fixed this by ensuring URL hashes are consistently decoded, making your link-based automations 100% reliable.
🔄 A Smoother "Resend to Failed" Experience
The "Resend to Failed Subscribers" button is a powerful tool for maximizing campaign reach. However, a pesky CSRF error could sometimes cause a "419 Page Expired" message. We've migrated this feature to use Inertia's modern request handling, eliminating the error and making the process faster and more integrated with the UI.
💼 Benefits & Use Cases
SaaS: Flawless Onboarding Journeys
With the link tracking fix, you can confidently create onboarding sequences where users clicking a link like /setup-guide#step2 are automatically moved to a "Completed Step 1" segment. Use the new Claude 4.5 Sonnet to generate clear, concise, and helpful onboarding emails that boost user activation.
E-commerce: Powerful Promotional Campaigns
Generate high-converting subject lines and product descriptions using GPT-5.2 Preview. When you send a campaign, the "Resend to Failed" feature now works seamlessly, ensuring you can easily retry sending to any subscribers who were initially missed due to temporary provider issues, maximizing your sales opportunities.
Agencies: Offer Cutting-Edge, Reliable Services
Assure your clients their marketing platform is stable and secure. Offer AI content generation as a premium service using the absolute latest models like Claude 4.5 Opus. The improved stability and detailed AI connection error logs mean less time troubleshooting and more time delivering value.
