Subject lines for asking customers for input.
Survey-request subjects work best when they're specific about the time commitment and the topic. 'Two questions — 30 seconds' beats 'We'd love your feedback!' by a wide margin. Naming the topic in the subject pre-commits the recipient to what they'll be answering ('Two questions about your trial experience') and lifts completion rates. Avoid 'Help us improve' framing — it shifts the work onto the recipient with no specific scope. The strongest patterns are bounded ('30 seconds'), specific (named topic), and honest about what comes next ('30 seconds — we'll share the aggregated answers next week').
