# Create a campaign

> The creation panel, then the settings: recipients, sender, tracking.

## The creation panel

**Campaigns → New campaign** (or <kbd>⌘</kbd> <kbd>K</kbd> then "New campaign").

| Field        | Notes                                                                                |
| ------------ | ------------------------------------------------------------------------------------ |
| **Name**     | Seen by the team only: "October newsletter".                                         |
| **Subject**  | What subscribers see first. You may change it later.                                 |
| **List**     | The list it goes to.                                                                 |
| **Template** | Optional: a [layout](/content/templates) whose editable zone the campaign will fill. |
| **Editor**   | Visual blocks, Markdown, HTML or MJML. See [The editors](/content/editors).          |

**Create the campaign** opens its **Content** tab. Everything stays changeable until it is sent.

## A campaign's tabs

| Tab            | Role                                                       |
| -------------- | ---------------------------------------------------------- |
| **Content**    | Subject, content, languages, A/B versions, preview, tests. |
| **Settings**   | Recipients, sender, tracking, A/B test, sending pace.      |
| **Delivery**   | The summary, sending, scheduling, following the progress.  |
| **Statistics** | The results.                                               |
| **Outbox**     | Every e-mail, recipient by recipient.                      |

At the top right: **Duplicate** (copies the campaign as a draft, content and settings included) and **Delete** (not while it sends).

## The settings

The **Settings** tab, saved with **Save the settings**.

### Campaign

<ParamField path="Name" type="text" required />

<ParamField path="List" type="list" required />

<ParamField path="Recipients" type="segment">
  **Everyone on the list**, or a [segment](/contacts/segments) of that
  list. The segments of another list appear once the change of list is
  saved.
</ParamField>

### Sender

<ParamField path="Sender address" type="e-mail">
  Empty: the list's own, then the application's. On a shared installation it
  has to belong to a [verified domain](/deliverability/domains).
</ParamField>

<ParamField path="Sender name" type="text" />

<ParamField path="Reply-to address" type="e-mail">
  Where your readers' replies land.
</ParamField>

The section header says which provider the campaign will leave through.

### Tracking

<ParamField path="Track opens" type="boolean" default="true">
  Adds an invisible pixel. Without it, there is no open rate and no "opened"
  segment.
</ParamField>

<ParamField path="Track clicks" type="boolean" default="true">
  Rewrites the links so that they go through Lekalao before their
  destination. Without it, there is no click map.
</ParamField>

<ParamField path="UTM source, UTM medium, UTM campaign" type="text">
  Added to every link so that your web statistics credit the visits to the
  campaign:
  `utm_source=newsletter&utm_medium=email&utm_campaign=christmas-2026`.
</ParamField>

<Tip>
  When you have verified a **tracking domain** (`click.your-domain.com`), the
  tracked links and the pixel use it instead of Lekalao's own address:
  better deliverability, and links that carry your name. See [Sending
  domains](/deliverability/domains#the-tracking-host).
</Tip>

### A/B test

See [A/B tests](/campaigns/ab-testing).

### Sending pace

<ParamField path="Spread the sending over" type="minutes" default="0">
  Spreads the e-mails evenly over the time you choose (up to 7 days). At
  zero, everything leaves at once, at the provider's pace. Mailboxes trust a
  steady sender more than one that empties a list in one go.
</ParamField>

<ParamField path="Local hour" type="boolean and hour">
  Each subscriber receives the e-mail at the chosen hour **of their own
  day**, going by their time zone (failing that the list's, failing that the
  application's). A campaign started on Monday at 15:00 "at 9:00 local time"
  leaves on Tuesday at 9:00 in Douala, Tuesday at 9:00 in Paris, and so on.
  Spreading starts from that hour.
</ParamField>

The [list's sending hours](/contacts/lists#sending-hours) add to this: an e-mail that would fall outside the window waits for it to open again.
