Hey there!
If we've just wrapped up a project together, first of all – thank you. It's been a pleasure working with you! Now, if you’ve got a minute or two, I’d love to hear what you thought of our cooperation and of my performance.
Your feedback helps me keep the good stuff going (and catch anything I might’ve missed). Plus, with your permission, I might feature your kind words on my website to inspire future collaborators!
No pressure – just be honest, be yourself, and write whatever feels right 😊.
Thank you very much!
