v0.4.0
Scheduled sending, activation codes, AI Agent overhaul, and onboarding redesign
v0.4.0
Release Date: January 12, 2026
This is a milestone release. Scheduled sending is finally here — one of the most requested features. We've also completely rebuilt the AI Agent to make it smarter and more reliable, and redesigned the onboarding flow from scratch to ensure every new user can get started in minutes.
✨ What's New
⏰ Scheduled Sending
No more waiting at your computer for the perfect send time.
- Flexible Scheduling — Pick any future time, and your emails will be sent automatically right on schedule
- Smart Timezone Handling — The system calculates send times based on your timezone, no manual conversion needed
- Reliable Task Queue — Background job system ensures scheduled emails are delivered on time, even if the server restarts
- Edit Before Sending — Modify or cancel scheduled campaigns anytime before the scheduled time arrives
- Batch Scheduling — Set different send times for multiple campaigns and plan your entire week's email strategy
Finally, you can set up Monday morning's promotional email before leaving work on Friday. Send your emails when recipients are most active and watch your open rates soar.
🎫 Activation Codes & Workspace Plans
More flexible subscription options to fit different needs.
- Instant Code Redemption — Enter an activation code to instantly unlock a workspace plan, no payment method required
- Team Bulk Activation — Enterprise customers can purchase multiple codes and distribute them to team members
- Transparent Plan Status — Clear display of your current plan type, remaining quota, and expiration date
- Smooth Upgrade Path — Upgrade from free to paid seamlessly with all your data intact
Whether you're an individual user or an enterprise team, you'll find the subscription model that works best for you.
🤖 AI Agent Complete Overhaul
We've rebuilt almost the entire AI Agent to make it a true email marketing assistant.
- Three Core Capabilities Enhanced — Email composition, campaign creation, and data analysis all significantly improved
- Deeper Context Understanding — AI now better understands your business context and generates more relevant content
- Smarter Email Generation — Optimized prompt engineering means AI-generated subject lines and body copy are more compelling
- Automatic Base URL Detection — AI-generated email links automatically use the correct domain, no manual edits needed
- Graceful Error Recovery — When AI encounters issues, it provides clear error messages and solution suggestions
Tell the AI what product you want to promote, and it'll draft the email, select the audience, and even suggest the best send time.
🎓 Onboarding Completely Redesigned
We listened to new user feedback and redesigned the onboarding flow from the ground up.
- Progressive Guidance — Features unlock gradually as you progress, not all dumped on you at once
- Interactive Tutorials — Each step involves hands-on actions, learning by doing is more effective
- Contextual Tips — Help appears when you need it most, not when you're busy with other things
- Skip Option — Power users can skip the tour anytime and dive right in
- Achievement Design — Positive feedback after each step makes getting started more enjoyable
From signup to sending your first email: 5 minutes on average.
🔧 Improvements
🔄 Workspace Switching Thoroughly Fixed
Multi-workspace users can finally switch with confidence.
- State Sync Perfected — When switching workspaces, all data (contacts, templates, campaigns) loads correctly
- Data Isolation Strengthened — Complete separation between workspaces, no cross-contamination
- Faster Switching — Optimized switching logic for quicker, smoother transitions
- Remember Last Selection — Automatically return to your last-used workspace on next login

📧 Email Delivery Reliability Dramatically Improved
We rebuilt the entire email queue system to ensure every email gets delivered.
- Smart Retry Mechanism — Automatic retries on failure, up to 3 attempts with exponential backoff
- Detailed Error Diagnostics — No more generic "send failed" messages, now you get specific reasons and solutions
- Queue Status Visualization — Clearly see each email's status: queued, sending, sent, or failed
- One-Click Resend — For transient errors, manually trigger a resend with a single click
- Database Lock Optimization — Rebuilt queue locking mechanism to avoid performance issues under high concurrency
Email delivery success rate improved to over 99.5%.
