The short answer: a customer feedback email that gets answers has a subject line that says what you want ("How was your visit, Sam?"), two or three sentences, one question or one button, a note on how long it takes, and a sign-off from a real person. Send it soon after the visit, order or project, and follow up once at most.
Below are 15 templates you can adapt: customer satisfaction survey emails, a one-click rating email, feedback requests for B2B clients, a reminder, and replies for when the feedback arrives. Plus 20 subject lines and the rules that keep these emails out of spam.
Key Takeaways
- Shorter surveys get finished. In SurveyMonkey's data, 10-question surveys average an 89% completion rate and 40-question surveys 79% (SurveyMonkey).
- The first question costs the most. Respondents spend about 75 seconds on question one, including reading the intro, and about 5 minutes on a 10-question survey (SurveyMonkey). Put the first question in the email itself.
- One email, one ask. A single button or a 1 to 5 rating row beats a paragraph of links.
- Follow up once. A single reminder catches people who meant to answer. More becomes noise.
- Follow email rules. Gmail requires authentication from every sender, and one-click unsubscribe on marketing email from anyone sending over 5,000 a day (Google). Promotional content brings in the CAN-SPAM Act (FTC).
- Keep survey rewards and review requests apart. Rewarding a private survey is one thing. Rewarding a public review breaks Google's policy.
What Makes a Feedback Email Work
| Part | What to write | Why |
|---|---|---|
| Subject line | Exactly what you're asking, in a person's voice | It's the only thing most people read |
| Opening | One line of thanks, naming the visit, order or project | Shows it's not a mass mailing |
| The ask | One question, or one button | Every extra choice loses people |
| Effort | "Takes 30 seconds" or "two questions" | People decide by effort |
| Why it matters | One sentence on what you'll do with it | Gives a reason to bother |
| Sign-off | A real name and role | People answer people |
| Footer | Your business name, address and an unsubscribe link | Required for some emails, good practice for all |
Put the first question in the email
The most effective format puts the first question inside the email: a row of five clickable ratings (1 to 5, or five faces), where each one is a link that records the answer and opens a short follow-up form. The customer has answered before they've decided whether to "take a survey". SurveyMonkey's timing data shows why this matters: the first question takes the longest, about 75 seconds including the intro, and later questions go faster (SurveyMonkey).
20 Subject Lines for Feedback Emails
| For | Subject line |
|---|---|
| A visit or appointment | How was your visit, [Name]? |
| Quick question about today | |
| Did we get it right today? | |
| One question about your visit to [Business] | |
| An order | How's your new [product]? |
| Quick question about your order | |
| Did your order arrive OK? | |
| Customer support | Did we fix the problem? |
| How did [Agent] do? | |
| Was this resolved? | |
| A survey | 2 minutes to help us improve? |
| Your opinion on [topic], in 3 questions | |
| Help us decide what to build next | |
| A B2B client | One question about last week's project |
| How are we doing so far? | |
| Before we start phase two | |
| Your honest take on our work this quarter | |
| Reminders | Still have a minute for that question? |
| Last chance to tell us how we did | |
| Replies | Thanks for your feedback, [Name] |
Avoid all caps, multiple exclamation marks and vague lines like "We value your feedback". They read as marketing, and a subject line that suggests a promotion can also change how the law treats the email (see the rules section below).

15. Thank you for your feedback (negative)
Subject: I'm sorry about your visit, [Name]
Hi [Name],
Thank you for telling us about [issue]. I'm sorry. That's not the experience we want anyone to have, and I appreciate you letting us know rather than just not coming back.
I'd like to put it right. Could I call you at a time that suits you? You can also reach me directly at [phone or email].
[Your name], [Role]
Bonus: replying to a suggestion. Keep it to two lines: "Thanks for the suggestion about [idea], [Name]. I've passed it to [team], and I'll let you know if we make the change."

When to Send, and How Often
- Soon after the experience. The same day for visits and appointments, a few days after delivery for orders, right after a ticket closes for support, and at milestones for projects.
- The same trigger for everyone. Send every customer the same request at the same point. If you later invite reviews, that consistency also keeps you clear of review gating.
- One reminder. A single follow-up a few days later, then stop.
- Don't over-survey regulars. If someone visits weekly, ask monthly or after milestones, not after every visit.
- Close the loop. If feedback leads to a change, tell the people who suggested it.
Should You Offer an Incentive?
For private feedback surveys, a small thank-you (a prize draw, a discount) can lift responses. Say so up front, and don't tie the reward to what people say. The FTC's rule on consumer reviews specifically bans incentives "conditioned expressly or by implication on" a review expressing a particular sentiment (16 CFR 465.4).
For public reviews, don't offer anything at all. Google's policy treats incentives for reviews, positive or not, as fake engagement (Google). The mistake to avoid is combining the two: "Fill in our survey and leave us a Google review for 10% off" breaks Google's rules for the review half.
The Rules: Deliverability, Unsubscribe and CAN-SPAM
- Authenticate your sending domain. Gmail requires SPF or DKIM from every sender, and SPF, DKIM and DMARC from anyone sending more than 5,000 emails a day to Gmail accounts. Those bulk senders also need one-click unsubscribe on marketing and subscribed messages, and every sender should keep reported spam below 0.3% (Google). If you send through a feedback or email platform, it should handle most of this.
- Know when CAN-SPAM applies. The CAN-SPAM Act's requirements apply to commercial email: messages whose primary purpose is to advertise or promote. If your feedback email includes promotional content, and especially if the subject line suggests a promotion, it can count as commercial. Commercial emails need honest headers and subject lines, your valid postal address, a clear way to opt out, and opt-outs honored within 10 business days (FTC).
- Include an unsubscribe link anyway. Even when the law doesn't strictly require one, a visible unsubscribe link is better than a spam complaint.
- Send from a real reply-to address. Many customers will reply to the email itself, especially B2B clients. Make sure someone reads those replies.
Email or Text?
Email suits longer surveys, B2B clients, and anything that needs context. Text suits a quick rating right after a visit. Many businesses use both: a text first for speed, with email for customers who don't have a mobile number on file. See our customer feedback text message templates for 30 SMS versions, each checked to fit in one message.
From Feedback to Reviews
Feedback and reviews do different jobs. Feedback tells you how you're doing. Reviews tell other customers. If you want both, give every customer who answers the same invitation to post a public review, whatever they said. Inviting only the people who gave high scores is review gating, which Google's policy bans, and the FTC says asking only happy customers could violate the FTC Act (FTC). More in how to ask for reviews.
How Spokk Helps
Spokk sends a short feedback form by email or text after every visit: classic, chat-style or a voice answer, in five languages. Low ratings reach you straight away so you can follow up, and every customer then gets the same invitation to review you on Google. Customers who want help writing get a draft built only from their own feedback, which they can edit before posting. On our platform, 1 in 3 feedback responses click through to the Google review page.

FAQs
How do you write an email asking for customer feedback?
Use a subject line that says what you're asking ("How was your visit, Sam?"), thank them in one sentence, ask one question with an obvious button or a 1 to 5 rating they can click in the email, say how long it takes, and sign off with a real name. Send it soon after the purchase or visit, and follow up once at most.
What should a customer satisfaction survey email include?
A clear subject line, a one-line thank-you, the reason you're asking, how long the survey takes, one button (or the first question right in the email), and a sign-off from a person. Keep the survey itself short: in SurveyMonkey's data, 10-question surveys average an 89% completion rate and 40-question surveys 79%.
What is a good subject line for a feedback email?
One that says exactly what you want and sounds like a person: "How was your visit, Sam?", "Quick question about your order", "Did we fix the problem?", or "One question about last week's project". Avoid all caps, exclamation marks and vague lines like "We value your feedback".
When should I send a customer feedback email?
Soon after the experience you're asking about: the same day for a visit or appointment, after delivery for an order, after a ticket is closed for support, and at milestones or the end of a project for B2B clients. Send one reminder a few days later if they haven't answered, then stop.
How do you reply to customer feedback by email?
Reply within a day or two, thank them by name, refer to what they actually said, and say what happens next: that you've shared it with the team, fixed the problem, or would like to call them. For negative feedback, apologize where it's appropriate and offer a direct way to reach a person.
Can I offer an incentive for filling in a feedback survey?
For a private survey, a small thank-you is generally fine, but say so up front and don't tie it to the answers being positive. Never offer anything for a public review: Google's policy bans incentives for reviews, and the FTC's rule bans rewards conditioned on positive reviews. Keep survey rewards and review requests separate.
Do feedback emails need an unsubscribe link?
Include one. If an email promotes anything, it's commercial under the CAN-SPAM Act and needs an opt-out honored within 10 business days and your postal address. Gmail also requires one-click unsubscribe for marketing messages from senders of more than 5,000 emails a day. A clear unsubscribe link costs nothing and protects your sender reputation.
