### 2. Quality HTML Outperforms Plain-Text

<Info>
  **The "plain-text is better" myth is wrong.** High-quality HTML emails achieve 20.5% higher inbox placement than plain-text.
</Info>

**Why:**

* Professional HTML signals legitimate business
* Better engagement metrics (2.5x more time spent)
* Plain-text associated with spam and low-effort outreach

### 3. Email Quality Matters

**Not all HTML is equal.** The distinction between high-quality and low-quality HTML is significant:

| Quality Level         | Inbox Placement | Engagement     |
| --------------------- | --------------- | -------------- |
| **High-Quality HTML** | 92.3%           | 24.3s avg time |
| **Low-Quality HTML**  | 78.4%           | 16.7s avg time |
| **Plain-Text**        | 71.8%           | 9.2s avg time  |

**What makes HTML "high-quality":**

* Clean code structure (semantic HTML)
* Cross-client compatibility (40+ clients)
* Dark mode optimization
* Mobile responsive design
* Proper email standards (CAN-SPAM, GDPR)
* Optimized assets (compressed images, alt text)
