# Introduction

Email analytics answer one question per email: is anyone reading it. Three rates, computed from the sends Meridian recorded and the events the mail provider reported back.

## The three rates

All three are computed over **delivered** sends: mail that bounced or was dropped never had a chance to be opened, so counting it would flatter or punish an email for the wrong reason.

| Rate | Definition |
| - | - |
| **Open rate** | Delivered sends that were opened, over delivered sends |
| **Click rate** | Delivered sends that were clicked, over delivered sends |
| **Click-to-open rate** | Of the sends that were opened, how many were clicked |

Open and click rates tell you whether the subject and the content are working. Click-to-open separates the two: a low open rate with a high click-to-open means the subject is the problem, not the email.

An email with **no delivered sends yet has no rates at all**: they're empty rather than zero, so a new email doesn't look like a failure.

## Where they show

* **Per email**, on its own page, next to the preview and its recent sends.
* **Across your active emails**, as averages above the [emails list](/emails), which is the quickest read on whether your lifecycle mail as a whole is landing.

Rates are recomputed as provider events arrive, so they move for a while after a send rather than being final immediately.

## Reading them honestly

Open tracking depends on the recipient's client loading a tracking pixel, and some privacy features load it for them or block it entirely. Treat open rate as a **trend on your own mail**, not an absolute number, and lean on clicks when a decision matters.

For delivery itself (bounces, complaints, suppression), see [Sends and deliverability](/email-sends).
