When is the best time to send an NPS survey?
Explains when to send transactional NPS after key interactions and when to run relationship NPS on a fixed cadence.
Send NPS when the customer’s experience is still recent: trigger transactional NPS right after an interaction, and run relationship NPS on a fixed cadence. (help.delighted.com)
When is the best time to send an NPS survey?
The best time is either immediately after a meaningful interaction (transactional NPS) or on a regular schedule that captures brand-level sentiment (relationship NPS). Transactional NPS should be sent close to the event that matters (order delivery, support ticket close, onboarding completion) so answers reflect that moment. Relationship NPS is calendar-based (quarterly, semi-annual or annual) to show trends across the whole customer base. Both approaches are complementary: transactional surveys drive operational fixes, while relationship waves track strategic progress. (info.nice.com)
When during the customer lifecycle should I send NPS?
Send transactional NPS at the lifecycle touchpoint you want to measure (post-purchase, post-fulfilment, post-support closure, or post-onboarding). Triggering within 1-7 days after the event is common for tangible outcomes (delivery or support); for experiences that require time (a SaaS feature) wait until the customer had a chance to use it. Relationship NPS belongs at points that represent overall experience, many companies run it quarterly or twice a year to avoid oversurveying while keeping trends visible. (nicereply.com)
How often should I repeat NPS surveys and to whom?
Repeat transactional NPS every time a customer completes the measured interaction, and repeat relationship NPS on a fixed rotation (quarterly or biannually) to a representative sample. Use rotating samples so the same individual isn’t surveyed too frequently; common rules are no more than once per quarter per person for relationship surveys. Avoid sending multiple NPS asks to the same customer within a short window to reduce fatigue and bias. If you rely mainly on transactional signals, aggregate them into a rolling brand NPS for reporting. (npsbench.com)
Does optimal timing vary by channel or industry?
Yes, channel and industry change the tradeoffs. Email or SMS are best for transactional triggers where you can tie the ask to a delivery or ticket; in-app or on-site widgets work well for product usage or checkout flows. B2B buyers and high-value accounts often expect a personal outreach or scheduled relationship survey; retail and e-commerce customers respond well to short post-purchase emails or thank-you page widgets. The practical differences:
| Channel | Best timing | Strengths | When it’s not ideal |
|---|---|---|---|
| 1-7 days after event or scheduled wave | Broad reach, easy automation. | Low open rates for cold lists. (uk.surveymonkey.com) | |
| SMS / Mobile | Within 24-72 hours after event | High visibility and fast responses. | Limited message length; regulatory considerations. (nicereply.com) |
| In-app / On-site (thank-you page) | Immediately on completion (thank-you/order status) | Highest contextual relevance; tied to order. | Only reaches customers who return to the site or app. (zigpoll.com) |
| Phone / Account-based | Scheduled or after major milestone | Deep qualitative follow-up for high-value customers. | Costly and time consuming for large samples. (davies-group.com) |
What changes this answer: regulation, sample size and the customer’s need for time to form an opinion. If your product needs days or weeks to reveal value (complex software, medical devices), delay transactional NPS accordingly. If you have short, frequent transactions (news apps, grocery), favor in-app micro-surveys and rolling samples to avoid repeats. Medallia and others warn that poor timing and frequency cause falling response rates, so test and monitor response rates and trend stability. (medallia.com)
If you want a tool that supports on-site, post-purchase, email and SMS NPS triggers tied to orders, Zigpoll is a practical option, it supports NPS, post-purchase and order-linked responses and offers a free Lite plan (50 responses/month) with paid plans shown as starting from $29/month (annual) on the vendor site. Prices and limits checked on Zigpoll’s pricing page as of November 6, 2026. (zigpoll.com)
Who this does not suit: programs that need a single universal cadence for every customer (that flattens actionable signal) or teams that can’t follow up on detractors quickly. When rapid remediation is the priority, transactional triggers win; when organizational benchmarking and board reporting are the goal, scheduled relationship waves win, they serve different purposes and are best used together.
