## What’s New in Solidrix Send 2.0
### 1. The Smart Airbag & Zero-Drop Defense 🛡️
Traditional email providers react to unexpected traffic surges by instantly suspending accounts or dropping emails without warning. If an attacker spams your signup endpoint, or an engineer writes an unthrottled `while` loop, your domain reputation is destroyed within minutes.
**Solidrix Send 2.0 changes this completely with the Smart Airbag:**
- **Velocity Spike Detection**: Evaluates rolling 5-minute sending velocity against your brand's safe baseline.
- **Zero-Drop Quarantine Buffer**: When an anomaly trips the circuit breaker, outgoing emails are **safely held in an isolated holding tank**. Not a single email is dropped or rejected.
- **1-Click Human-in-the-Loop Review**: Administrators can inspect quarantined payloads in a visual sandbox and choose to **"Allow & Release"** (dispatching seamlessly via background workers) or **"Reject & Purge"** (auto-suspending compromised API keys).
### 2. Multi-Provider Failover & Intelligent Routing ⚡
Your email delivery layer should never depend on a single vendor. AWS SES, Resend, Zoho, Brevo, and Mailgun all experience outages.
With Solidrix Send 2.0:
- Configure **Primary** and **Standby** gateways.
- Under normal operations, route high-volume traffic through cost-effective bulk gateways like AWS SES ($0.10 / 1,000 emails).
- If the primary gateway suffers latency spikes, 5xx outages, or exhausts daily quota, traffic **automatically fails over to Resend or Postmark within milliseconds**.
### 3. Mandatory Custom Tracking Domains (CNAME Verification) 🌐
In legacy platforms, tracking links for all users ran through a single corporate domain (e.g. `send.solidrix.com`). If one bad actor sent spam, Gmail and Microsoft blacklisted the shared domain, ruining deliverability for all honest senders.
Solidrix Send 2.0 strictly enforces **Custom Tracking Domains**:
- Every brand uses an isolated CNAME record (e.g. `send.yourbrand.com` pointing to the router).
- Eliminates cross-tenant contamination.
- Automated real-time DNS verification with instant status updates.
### 4. High-Performance Sharded Campaign Dispatch 🚀
Broadcasting to lists of 500,000+ subscribers previously caused PHP memory exhaustion and queue starvation. Solidrix Send 2.0 introduces:
- **Cursor-based batch chunking** in blocks of 100 subscribers.
- Dispatched across dedicated Redis queue shards (`campaign-shards`).
- Sub-second dispatch velocity without worker memory leaks.
### 5. Automated Global Suppression Engine 🛑
- Immediate suppression of hard bounces and spam complaints.
- Redis-backed cache lookups before gateway handoff ensure your account never re-attempts sending to dead mailboxes.
- 1-Click unblock with atomic Redis eviction.
