About this template

NPS Survey Email — Free Net Promoter Score Feedback Email Template

NPS Survey Email template: A one-question Net Promoter Score (NPS) survey email: "How likely are you to recommend us to a friend?" with a row of eleven clickable 0–10 scores that each open your survey with the score filled in, "not likely" and "very likely" labels, a time estimate, a link for longer feedback and a thank-you note.

NPS Survey Email is a free, responsive HTML template for measuring Net Promoter Score (NPS) right inside the inbox. It asks the classic question, "How likely are you to recommend us to a friend or colleague?", with a row of eleven clickable scores from 0 to 10. One click records the answer, which is why one-question, in-email surveys get far more responses than a link to a long form.

One click from the inbox

Email can't run forms reliably, so each number is a normal link: the score is added to the end of your survey link, for example …&score=9, and your survey tool or landing page records it and can ask a follow-up question. Scores 0 to 6 have a light red tint, 7 and 8 amber and 9 and 10 green, a subtle nod to how NPS groups detractors, passives and promoters, with "Not at all likely" and "Extremely likely" labels under the ends of the scale.

How NPS works

Net Promoter Score is the percentage of promoters (9–10) minus the percentage of detractors (0–6), giving a number from −100 to 100. It's one of the most widely used customer loyalty metrics, and tracking it over time shows whether customer experience is improving. The optional "Share detailed feedback" button lets people who want to say more go straight to a longer form.

Works with your survey tool

Use it with Delighted, Typeform, SurveyMonkey, Hotjar, Qualtrics, Google Forms or your own endpoint, and send it from Customer.io, HubSpot, Intercom, Klaviyo or your own code. Built with tables and inline styles, an Outlook-safe button, a dark palette and a plain-text version that lists a link for each score. Send it after a customer has had time to experience your product, for example 30 to 90 days after sign-up, and use the Review Request template for product reviews.

Extend with AI

Take This Email Further With AI

Give this prompt to an AI assistant to write your own version of the NPS Survey Email email: draft ten subject lines and preheaders, adapt the copy for a customer segment, translate it, convert it to MJML or React Email, or write the plain-text version. Then paste the result back into the editor above to check it in desktop, mobile and dark mode.

Create a responsive HTML email: “NPS Survey Email”, an onboarding email.

Purpose: A one-question Net Promoter Score (NPS) survey email: "How likely are you to recommend us to a friend?" with a row of eleven clickable 0–10 scores that each open your survey with the score filled in, "not likely" and "very likely" labels, a time estimate, a link for longer feedback and a thank-you note.

Inbox text:
- Subject line: “Quick question: would you recommend Acme?”
- Preheader (hidden preview text): “One click is all it takes. Your answer helps us decide what to build next.”

Content, top to bottom:
- Question & message
- Score scale Main button: “Share detailed feedback”.
One primary action only, with short body text, so a new user knows exactly what to do next.

Build it like a professional email developer:
- Table-based layout, 600px wide on desktop and fluid on mobile (width 100%, max-width 600px).
- Inline CSS on every element, with one small style block only for media queries and dark mode (prefers-color-scheme).
- A bulletproof, Outlook-safe call-to-action button (padded table cell with a VML fallback), never an image.
- Colours: brand and button #1d4ed8, button text #ffffff, page background #eef0f7. Web-safe font stack with a fallback after the brand font.
- Every image has alt text and explicit width and height. Use PNG icons, never SVG, because Gmail and Outlook drop them.
- Hidden preheader text, a plain-text version, and a legal footer with the postal address, the reason the person is receiving it and a working unsubscribe link.

Finish with a short checklist of what to test in Gmail, Outlook for Windows, Apple Mail, mobile and dark mode.

Frequently Asked Questions

An email that asks one question, how likely the customer is to recommend you on a scale of 0 to 10, so you can calculate your Net Promoter Score. The best NPS emails let people answer with one click from the inbox.

Subtract the percentage of detractors (scores 0 to 6) from the percentage of promoters (scores 9 and 10). Passives (7 and 8) count toward the total responses but not either group. The result ranges from −100 to 100.

Each number links to your survey link with the score added at the end, for example https://webdevpuneet.com/survey?score=9. Your survey tool or landing page reads the score, records it and can ask an optional follow-up question.

After customers have had enough time to form an opinion, such as 30 to 90 days after sign-up or a week after delivery, and then every few months. Avoid surveying the same person too often.

It is safest to include one, especially if you survey customers regularly, so the footer has an unsubscribe link and your postal address.

It saves an editable copy of your NPS Survey Email in My Code, the UI Snippets code editor: the email markup goes in the HTML panel and its CSS (mobile and dark-mode rules plus fonts) in the CSS panel, so you can keep refining the code and save your own versions.
