When to Send a Review Request Email: What the Data Actually Says

There's no single universal "best time" — the ideal delay between service and request depends heavily on what kind of experience you're asking someone to remember. For physical products, waiting 7–8 days after delivery shows response rates of 18–22%, compared to just 8–10% for requests sent only 3 days out — the customer needs time to actually use the thing first. For services, it's the opposite: send within 24–48 hours, while the experience is still vivid, because unlike a product, there's nothing left to "try" after the appointment ends and the details fade fast.

Timing research on review-request emails consistently finds the same pattern: sending midweek can lift response rates by up to 10% compared to Monday or Friday sends, and the best window within the day is 10 AM to 2 PM in the customer's local time zone. A request sent Friday afternoon is competing with weekend inbox neglect; the same email sent Tuesday at 11 AM isn't.

• Send the first request on the recommended schedule for your business type.
• If there's no response, send exactly one follow-up, 5–7 days later.
• Stop after that. More than two total sends starts to read as pressure rather than a reminder, and can hurt brand perception more than the missed review costs you.
