# About the Campaign API

With the Campaign API you can create and manage email marketing campaigns for a Wix site, including composing content, publishing to contacts, and tracking engagement statistics.

With the Campaign API, you can:

- [Create](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/campaign/create) campaigns from editor data.
- [Retrieve](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/campaign/get-campaign) information about a campaign.
- [List](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/campaign/list-campaigns) all campaigns for a site.
- [Publish](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/campaign/publish-campaign) a campaign and send it to contacts.
- Send a [test email](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/campaign/send-test) to preview how a campaign will look in an inbox.
- [Reschedule](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/campaign/reschedule) a scheduled campaign.
- [Resend](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/campaign/resend-to-non-openers) a campaign to recipients who didn't open the original email.
- [Reuse](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/campaign/reuse-campaign) an existing campaign to create a draft copy.
- Retrieve [statistics](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/campaign/list-statistics) and [recipients](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/campaign/list-recipients) for a campaign. Statistics are available only for published campaigns.

## Creating a campaign

Use [Create Campaign](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/campaign/create) to create a new draft campaign from editor data. Pass the `composerDataJson` field with the campaign's content and set `campaignEditorType` to match the format you're using.

The `composerDataJson` field supports three formats, determined by `campaignEditorType`:

- `WEB`: Wix proprietary JSON format for the classic drag-and-drop editor.
- `MOBILE`: A subset of the `WEB` format for the classic mobile editor.
- `MJML`: MJML markup wrapped in a JSON object under key "mjml".

Passing a format that doesn't match the specified `campaignEditorType` doesn't return an immediate error, but causes the campaign to fail silently when previewing or sending. `MJML` is the most straightforward format to generate programmatically.

You can also set an optional `emailPreheader` when creating or updating a campaign. This is short preview text shown after the subject line in many email clients and can improve open rates.

After creating a campaign, you can update its content with [Update Composer](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/campaign/update-composer) or render a preview with [Preview Campaign](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/campaign/preview).

The `campaignEditorType` can't be changed after a campaign is created. Passing a `composerDataJson` in a different format when calling Update Composer causes a silent failure when sending or previewing.

If your campaign content contains dynamic placeholders for personalization, pass a `placeholders` map to [Preview Campaign](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/campaign/preview) to resolve those tokens in the preview. Set default placeholder values in `composer.defaultValues` to use as fallbacks when actual recipient values aren't available.

To retrieve a campaign's subject line, use [Get Composer](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/campaign/get-composer). The `emailSubject` field on the [Campaign](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/campaign/campaign-object) object is deprecated.

## Publishing a campaign

To publish a campaign, sender details must be set up for the site. Call [Identify Sender Address](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/campaign/identify-sender-address) to determine which email address will appear as the "From" address.

Call [Publish Campaign](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/campaign/publish-campaign) to send the campaign:

- Pass `emailDistributionOptions` to distribute the campaign by email to contacts. Campaigns can only be sent to Wix site contacts, defined by contact IDs, contact labels, or segment IDs.
- Omit `emailDistributionOptions` to publish the campaign as a landing page only, without sending any emails. This decision is permanent — once published as a landing page only, the campaign can't be sent by email. Use [Reuse Campaign](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/campaign/reuse-campaign) to create a new draft copy if you need to send emails later.

The response always includes a `landingPageUrl` that can be shared on social media, regardless of whether emails are sent.

You can schedule a campaign to send at a future time by passing `emailDistributionOptions.sendAt`. The scheduled time must be at least 30 minutes in the future. Use [Pause Scheduling](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/campaign/pause-scheduling) and [Reschedule](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/campaign/reschedule) to adjust a scheduled campaign before it sends.

## Email distribution process

After publishing with email distribution, the campaign moves through the following `distributionStatus` values:

1. `SAMPLING`: A small subset of the audience receives the email first. The system checks for issues such as spam-trap hits or excessive bounce rates.
2. `SENDING`: Sampling passed and the email is being sent to the full audience.
3. `DISTRIBUTED`: The email has been sent to all recipients.
4. `TERMINATED`: Sampling failed due to quality issues. The campaign is stopped before reaching the full audience. A terminated campaign can be reused with [Reuse Campaign](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/campaign/reuse-campaign) to create a new draft for republishing.
5. `REJECTED`: The campaign was identified as abusive and blocked before sending.

## Paused campaigns and audience retrieval

When a scheduled campaign is paused with [Pause Scheduling](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/campaign/pause-scheduling), the original audience settings are preserved. Use [Get Audience](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/campaign/get-audience) to retrieve those audience settings so you can pass them back when republishing the campaign.

## Resending to non-openers

Use [Resend to Non-Openers](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/campaign/resend-to-non-openers) to send a follow-up to recipients who didn't open the original campaign email. The following conditions must be met:

- The original campaign was sent at least 24 hours ago.
- There are recipients who received the email but didn't open it.
- Resend to Non-Openers hasn't already been called for this campaign.

An optional different subject line can be passed to improve open rates on the follow-up.

## Before you begin

It's important to note the following points before starting to code:

- Each site has an email quota per billing period that depends on the [email marketing plan](fallback::https://support.wix.com/en/article/email-marketing-upgrading-your-email-marketing-plan).
- The site's email marketing account must be active. A site owner can be blocked from using email marketing for not complying with the [Wix Email Marketing Terms of Use](fallback::https://www.wix.com/shoutout/terms-of-use). Use [Get Account Details](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/account-details/get-account-details) to check the account status before publishing.
- Sender details must be configured before publishing a campaign.
- Campaigns can only be sent to Wix site [contacts](fallback::https://dev.wix.com/docs/rest/crm/members-contacts/contacts/contacts/contact-v4/introduction).

## Use cases

- [A/B test email subject lines](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/campaign/sample-use-cases-and-flows)

# Campaign API: Sample Flows

This article presents possible use cases and corresponding sample flows that you can support. It provides a useful starting point as you plan your implementation.

## A/B test email subject lines

A marketing team wants to determine which subject line drives higher open rates before committing to a full send. They run two variants of the same campaign with different subject lines, measure the results, and send the winning variant to the rest of the audience.

> **Prerequisite:** Create and publish two campaigns with different subject lines before running this flow.

To A/B test email subject lines:

1. Call [List Campaigns](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/campaign/list-campaigns) to retrieve the campaign IDs for both campaigns. Save the IDs for later.
1. Call [List Statistics](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/campaign/list-statistics) and pass both campaign IDs. Compare the `email.opened` count for each campaign to determine which subject line performed better.
1. Call [List Recipients](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/campaign/list-recipients) for the winning campaign with `activity` set to `CLICKED` to identify the most engaged recipients.
1. Call [Label Contact](fallback::https://dev.wix.com/docs/rest/crm/members-contacts/contacts/contacts/contact-v4/label-contact) to tag the clicked recipients with a label for future targeting.
1. Call [Reuse Campaign](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/campaign/reuse-campaign) on the winning campaign to create a draft copy.
1. Call [Publish Campaign](fallback::https://dev.wix.com/docs/api-reference/business-management/marketing/emails/email-marketing/campaign/publish-campaign) with the label ID from step 4 in `emailDistributionOptions.labelIds` to send the refined campaign to the engaged audience.
