Subject line examples for email JSON prompts
See how subject-line style changes the prompt for promo emails, welcome messages, and activation sequences.
{
"task": "Write a promotional email for a spring software discount",
"language": "en",
"output_format": "json",
"email_type": "promo_campaign",
"subject_line_style": "benefit_plus_urgency",
"personalization_level": "medium",
"preview_text_style": "specific_and_short"
}Subject lines shape expectation before the email is even opened, so the prompt should treat them as a separate strategy layer.
Common subject-line directions
- Benefit-first
- Curiosity-led
- Urgency plus offer
- Personal and conversational
When personalization helps
Personalization improves relevance when it is tied to behavior, lifecycle stage, or account context instead of using shallow name insertion.
