One small update since [month]
Type: Product update, Winback, Marketing
Tone: Informative, confident, restrained
Product-led re-engagement subject lines win when the update feels concrete.
Pick one update that solves a known blocker. Mention the outcome in the first paragraph, and then add one short proof point, such as a customer quote or a “before and after” example.
Avoid hype words. If the update requires setup, mention the time cost in plain language.

For best results, send the email at peak open times, usually mornings or early afternoons.
