# Email Spam Checker

> Verify your email deliverability and identify spam triggers before you send.

## Overview

The **Email Spam Checker** is a specialized tool designed to help you optimize your emails for the primary inbox. By analyzing your subject line and email body in real-time, Nudgen identifies potential **Spam Triggers** and calculates a **Spam Score** to guide your edits.

Using the tool ensures that your messages aren't intercepted by aggressive spam filters, protecting your sender reputation and maximizing your campaign engagement.

## Key Features

### Spam Score

Nudgen provides a dynamic radial gauge that represents the overall risk level of your email content. The score ranges from 0 to 100, where a higher score indicates a cleaner, safer email.

* **Good (Emerald)**: Your email is well-optimized and highly likely to land in the primary inbox.
* **Caution (Amber)**: Some elements may cause concern for strict filters. Review the suggested improvements.
* **Risky (Rose)**: Significant spam triggers detected. High probability of being flagged as spam.

### Spam Triggers

The analysis panel highlights specific words and phrases that are commonly flagged by major email providers (like Gmail or Outlook). These "Spam Triggers" include:

* **Urgency Hooks**: Phrases like "Act Now," "Urgent," or "Last Chance."
* **Financial Claims**: Words like "Free," "Cash," or "No Credit Check."
* **Formatting Issues**: Excessive capitalization, aggressive punctuation (!!!), or suspicious link-to-text ratios.

### Real-time Interaction

As you type in the editor, Nudgen automatically re-evaluates your content. This "debounced" instant feedback allows you to see exactly how changing a single word impacts your overall deliverability.

## Best Practices

To ensure the best possible deliverability score, consider the following tips:

1. **Avoid Clickbait**: Keep your subject lines honest and relevant to the content.
2. **Balanced Formatting**: Use standard capitalization and avoid excessive bolding or colors.
3. **Minimize Junk Words**: Replace high-risk marketing jargon with direct, value-driven language.
4. **Test Before Sending**: Always run your final draft through the Spam Checker before launching a campaign.
