# Email Copywriting — Email Copywriting Methodology

Writing techniques specific to the email medium, used by the copywriter agent when crafting newsletters.

## Why Email Copy Is Different

Blog posts are found via search. Social media posts are discovered in feeds. Emails must be **opened from the inbox** to be read. The battle is won or lost at the subject line, and within 7 seconds of opening, readers decide whether to scroll or close.

## Subject Line Design: The CURVE Framework

| Element | Description | Example |
|---------|-------------|---------|
| **C**uriosity | Create an information gap | "The email secret most marketers don't know" |
| **U**rgency | Create time pressure | "Only until midnight — sharing this strategy" |
