Today marks a major milestone for Sunnybox with the release of version 2.0. After months of development and valuable feedback from our community, we’re excited to share what we’ve built: a faster, more reliable, and incredibly powerful email API platform.
What’s New in 2.0?
Simpler API, Better Performance
We’ve streamlined our API to make it easier to use and faster to respond:
- 30% faster response times across all endpoints
- Cleaner URLs without version numbers (your integrations stay stable)
- 50% reduction in API calls needed for common operations
- 2x faster email processing in background jobs
Choose Your Webhooks
Tired of getting flooded with webhooks you don’t need? Our new event system lets you pick exactly what you want to know about:
- Subscribe to specific events like “message.received” or “job.failed”
- Reduce webhook traffic by up to 90% by only getting what matters
- Discover all available events with our new events endpoint
- Filter by provider to only get events for specific email accounts
For example, if you only care about new messages and failed sends, just subscribe to those two events. No more filtering through noise.
Full Draft Support
Email drafts are now fully supported, making Sunnybox perfect for email clients and CRM systems:
- Save drafts with all formatting and attachments preserved
- Edit and update drafts as many times as needed
- Send when ready with a single API call
- Automatic sync with Gmail and IMAP providers
Enterprise-Grade Security
We’ve significantly enhanced security across the platform:
- Webhook signatures to verify requests are really from Sunnybox
- Granular permissions to control exactly what each API key can do
- Encrypted provider credentials with industry-standard encryption
- Comprehensive audit logging for compliance requirements

Managing emails is now more powerful and intuitive:
