Prove the risky pieces first.
Milestone 2
Build Campaign
Import recipients, map columns, select a draft, validate merge fields, and preview samples.
Milestone 3-4
Send Safely
Test sends, launch confirmation, queued scheduling, and the DigitalOcean worker.
Milestone 5-6
Measure
Open, click, unsubscribe, bounce parsing, suppression, and auto-pause safety.
Gmail draft templates
The app reads existing Gmail drafts, freezes personalized content at launch, and preserves attachments without mutating the original draft.
Droplet scheduler
Vercel hosts the app and tracking endpoints; the DigitalOcean worker owns minute-level queue processing and send pacing.
Tracking by toggle
Open, click, bounce, and unsubscribe tracking are individually controlled, with raw events retained and bot-like events marked.
