Email templates for asking customers for feedback
Three short emails to adapt: after sign-up, after a first success, and after someone goes quiet. Copy, change two lines, send.

Short answer: keep it short, ask one specific thing, make it obviously from a person, and make replying easy. Choose the example that matches what the person has actually done.
After sign-up
Template
Subject: Quick question about why you signed up
Hi {first name},
Thanks for trying {product}. I’m {your name}, one of the people building it.
What were you hoping it would help with? Just hit reply, a sentence is plenty.
{your name}After their first success
Template
Subject: How did {first task} go?
Hi {first name},
I saw you {did the first meaningful thing}. Nice.
Was anything harder than it should have been? I read every reply and fix what I can.
{your name}After a quiet week
Template
Subject: Did something get in the way?
Hi {first name},
You signed up for {product} last week and I noticed you haven’t been back. No pressure at all.
If something didn’t work or wasn’t clear, I’d really like to know. Reply with a word or two and I’ll take a look.
{your name}What makes these work
- A real name and a reply-to address that reaches a person.
- One question per email.
- No survey link in the first email; a reply is lower effort.
- Sent when the moment is fresh, not in a monthly batch.
