Write subject line copy

Write three subject line options for the June sale email to test with 20% of the list: a straightforward option that highlights the 30% off deal, a curiosity option that teases an extra surprise at checkout, and a urgency option that uses the Friday deadline. Keep each under 50 characters and avoid all caps or excessive punctuation. I will send these to Priya for approval.

Before I send the subject lines to Priya in acquisition, make them approval-ready: surface the savings figure early, suggest one version that references the recipient's past purchase category, flag any words that could trigger spam filters, and recommend which two to A/B test based on likely open-rate lift.

Marketing asked for a high-open subject and legal insists we state the discount clearly. The email goes to 200,000 subscribers and Priya expects data-backed advice. I don't know whether to prioritize curiosity or explicit savings. Given this conflict, what subject line approach is most likely to balance legal comfort and lift, and which exact phrasing should I send to Priya to test first?

Over the last six campaigns our new subject lines rarely beat the control, wasting list segments and time. I want a habit change that improves wins: what three simple rules about structure, length, and personalization should I adopt, and one easy testing plan so we learn something useful every send?
