# What is the sent-unchanged rate?

The sent-unchanged rate is the share of AI-written drafts sent to customers exactly as written, without a single edit. You count it yourself from your own replies, which makes it an honest, easy-to-check measure of whether drafts are good enough to send.

It is the other side of the [edit rate](https://replypen.com/glossary/edit-rate.md): if a quarter of drafts are edited, the
rest went out unchanged. The difference is the question each number answers. The sent-unchanged rate
asks "how often could I just press send?", which is the time you actually save.

## Why it matters

Vendor numbers such as a [resolution rate](https://replypen.com/glossary/resolution-rate.md) are counted by the vendor,
under a definition the vendor chooses. The sent-unchanged rate is counted from what you did with
each draft, email by email, in your own inbox. It is also the number to watch before trusting a tool
with more: when drafts for one kind of email are almost always sent unchanged, that kind of email
needs less review.

Track it per kind of email and week by week. One overall number hides the difference between order
questions, which may be easy, and complaints, which may not be.

## An example

In a week, thirty of forty drafts were sent as written. The sent-unchanged rate is three out of four,
and the ten edits tell you where to look.

**In ReplyPen:** Reports show how many Drafts you sent unchanged and how many you edited, week by week. More in
