+# The emails property is an array of email objects.
+{
+  "links": {

+    "emails.campaign": "https://api.getdrip.com/v2/{emails.account}/campaigns/{emails.campaign}"

+    "href": "https://api.getdrip.com/v2/9999999/campaigns/123456/emails/7654321",
+    "sending_delay": 0,
+    "sending_order": 0,
+    "subject": "Welcome to the course, {{ subscriber.first_name }}",
+    "html_body": "<html><body><h1>Welcome!</h1></body></html>",
+    "text_body": "Welcome!",
+    "created_at": "2026-06-21T10:31:58Z",

+      "account": "9999999",
+      "campaign": "123456"
+    }
+  }]
+}
+```
+
+Returns every email in the Email Series Campaign in sending order, including drafts, which are
+not sent and are not marked as drafts in the response. The list is not paginated.
+
+`sending_delay` is how long Drip waits before sending the email, counted from the previous email
+or, for the first email, from when the person subscribed unless the campaign has
+`start_immediately`. Its unit (minutes, hours, or days) is set in the Email Series Campaign and
+is not part of the response. For an email's performance, use
+[Fetch email metrics](#fetch-email-metrics). Liquid in `subject`, `html_body`, and `text_body` is
+returned as written, not rendered for a subscriber.
+
+### HTTP Endpoint
+
+`GET /v2/:account_id/campaigns/:campaign_id/emails`

+part of it.
