Demo: an email to Sarah Miller is typed and sent; she reacts "Finally, a clear email!" and the score reaches 92 out of 100.

How it works

Three minutes, one email, real feedback.

  1. 01

    Read the situation

    The context, the recipient and their personality, what you need to get. Like at work, in three lines.

  2. 02

    Write your email

    On your own, no template, no assistant. Subject, body, sign-off: it's all yours.

  3. 03

    Watch them read

    The recipient reads your email in front of you: their thoughts, their reaction, then a score out of 100 and one thing to work on.

Before / After

Same situation, two emails.

Sarah expects the quarterly report on Thursday. It will be ready on Monday. Here are two ways to tell her.

Before

SubjectQuick question

Hello, I hope this email finds you well. I just wanted to touch base about the report, as there have been quite a few issues lately with various things that didn't necessarily arrive on time, so Thursday might be a bit tricky, but I'm doing my best of course and I'll keep you posted as soon as I can. Don't hesitate to reach out. Regards

After

SubjectQuarterly report: delivery Monday morning

Hi Sarah, Finance sent their numbers three days late, so I won't be able to deliver the quarterly report on Thursday. Can I send it to you Monday at 10am instead? Let me know if that works. Best regards, Alex
