How to ask for feedback by email (and actually get honest answers)

Hi [Name],

Now that [project] has wrapped, I'd value your honest read on how I handled it — I'm actively trying to improve on [dimension, e.g., stakeholder communication].

Three specific questions:
1. What's one thing I should do differently next time?
2. Was there any point where you felt you had to step in or double-check my work?
3. What should I keep doing?

Happy to grab 15 minutes instead if that's easier than writing.

Thanks,

Hi [Name],

With [project] delivered, I'd love two minutes of honest feedback — it directly shapes how we work.

- What's one thing we could have done better?
- On a 0–10 scale, how likely would you be to recommend us — and what would have made it a 10?

And if you were happy with the work, a short testimonial or a referral would mean a great deal to us — but the honest answers matter more.

Thank you!

Hi [Name],

You see my work up close, so I'd genuinely value your take. No need to sugarcoat — the useful stuff is usually the uncomfortable stuff.

Two questions:
1. What's something I do that makes your work harder?
2. What do you think I underestimate about how I come across?

Coffee's on me either way, and I'm happy to return the favor.

Thanks,
