在此頁面上：設定定義登陸頁面URL的子網域，重複使用已委派給Adobe的網域，或設定新的網域。
開始使用登陸頁面子網域 gs-lp-subdomains
若要能夠建立登陸頁面預設集，您必須設定您將用於登陸頁面的子網域。
您可以使用已委派給Adobe的子網域，也可以設定另一個子網域。 在本節中進一步瞭解將子網域委派至Adobe。
登陸頁面子網域設定是所有環境通用。 因此：
-
若要存取及編輯登陸頁面子網域，您必須對生產沙箱具有 管理登陸頁面子網域 許可權。
-
對登陸頁面子網域所做的任何修改也會影響生產沙箱。
使用現有的子網域 lp-use-existing-subdomain
若要使用已委派給Adobe的子網域，請遵循下列步驟：
-
存取管理 > 管道功能表，然後選取登陸頁面設定 > 登陸頁面子網域。
-
按一下設定子網域。
-
從 組態型別 區段中選取使用委派網域。
-
輸入要顯示在登入頁面URL中的前置詞。
只允許使用英數字元和連字型大小。
note caution CAUTION 請勿使用 cdn或data首碼，因為這些首碼保留供內部使用。 其他限制或保留的前置詞（例如dmarc或spf）也應避免。 -
從清單中選取委派的子網域。
您無法選取已用作登陸頁面子網域的子網域。
請注意，您無法使用相同上層網域的多個委派子網域。 例如，如果「marketing1.yourcompany.com」已針對您的登陸頁面委派給Adobe，您將無法使用「marketing2.yourcompany.com」。 不過，支援登陸頁面的多層子網域可繼續使用「marketing1.yourcompany.com」的子網域（例如「email.marketing1.yourcompany.com」）或不同的上層網域。
note caution CAUTION 如果您選取使用CNAME方法委派給Adobe的網域，您必須在您的代管平台上建立DNS記錄。 若要產生DNS記錄，此程式與您設定新登陸頁面子網域時的程式相同。 在本節中瞭解如何操作。 -
按一下提交。
-
提交後，子網域會顯示在狀態為 處理中 的清單中。 如需子網域狀態的詳細資訊，請參閱本區段.
您必須等到Adobe執行必要的檢查（最多可能需要4小時.），才能使用該子網域傳送訊息。
-
檢查成功後，子網域會取得 Success 狀態。 它已準備好用來建立登入頁面預設集。
設定新的子網域 lp-configure-new-subdomain
若要設定新的子網域，請遵循下列步驟。
-
存取管理 > 管道功能表，然後選取登陸頁面設定 > 登陸頁面子網域。
-
按一下設定子網域。
-
從 組態型別 區段中選取新增您自己的網域。
-
指定要委派的子網域。
note caution CAUTION -
您無法使用現有的登陸頁面子網域。
-
子網域中不允許使用大寫字母。
不允許將無效的子網域委派給Adobe。 請務必輸入貴組織所擁有的有效子網域，例如marketing.yourcompany.com。
對於登入頁面，支援多層級子網域。 例如，您可以使用「email.marketing.yourcompany.com」。
-
-
將會顯示要放置在DNS伺服器中的記錄。 複製此記錄或下載CSV檔案，然後導覽至您的網域託管解決方案，以產生相符的DNS記錄。
-
請確定已在您的網域託管解決方案中產生DNS記錄。 如果所有專案皆已正確設定，請勾選「我確認……」方塊，然後按一下提交。
當您設定新的登陸頁面子網域時，它一律會指向CNAME記錄。
-
提交子網域委派後，子網域會顯示在狀態為 處理中 的清單中。 如需子網域狀態的詳細資訊，請參閱本區段.
您必須等到Adobe執行必要的檢查（最多可能需要4小時.），才能將該子網域用於您的登陸頁面
-
檢查成功後，子網域會取得 Success 狀態。 它已準備好用來建立登入頁面預設集。
請注意，如果您無法在託管解決方案上建立驗證記錄，子網域將會標示為失敗。
取消委派子網域 undelegate-subdomain
如果您想要取消委派登入頁面子網域，請遵循下列步驟。
Adobe處理您的請求後，未委派網域不再顯示在子網域詳細目錄頁面上。
This section contains structured knowledge intended to support interpretation, retrieval, and question answering related to this topic.
For complete understanding, this information should be combined with the documentation on this page. Neither source is intended to stand alone; the page describes the feature, while this section provides additional context that helps disambiguate terminology, intent, applicability, and constraints.
- TL;DR: This page explains how to configure, use, and undelegate the subdomains used to build landing page URLs, either by reusing a subdomain already delegated to Adobe or by delegating a new one.
Intents
- Reuse a subdomain already delegated to Adobe for landing pages.
- Configure a new subdomain for landing pages by generating a matching DNS record.
- Identify which subdomain prefixes are reserved or restricted before submitting a configuration.
- Check the delegation status of a landing page subdomain.
- Configure a WAF IP allowlist for a delegated landing page subdomain.
- Undelegate a landing page subdomain that is no longer needed.
Glossary
- Landing page subdomain: the subdomain used to build a landing page URL, either reused from an existing Adobe delegation or newly delegated for that purpose.
- Prefix: the alphanumeric and hyphen string entered by the user that displays in the landing page URL, combined with the selected subdomain.
- Delegated subdomain (product-specific): a subdomain already delegated to Adobe that can be reused as a landing page subdomain.
- Landing page preset: the configuration object that requires a landing page subdomain to be set up beforehand, from which its subdomain name is picked.
Guardrails
- The Manage Landing Page Subdomains permission on the production sandbox is required to access and edit landing page subdomains.
- Landing page subdomain configuration is common to all environments; any modification to a landing page subdomain also impacts the production sandboxes.
- Only alphanumeric characters and hyphens are allowed in the prefix.
- The
cdnanddataprefixes cannot be used, as they are reserved for internal use. - The
dmarcandspfprefixes should also be avoided (recommended). - A subdomain that is already used as a landing page subdomain cannot be selected again.
- Multiple delegated subdomains of the same parent domain cannot be used for landing pages; however, multi-level subdomains of an already-used parent domain are supported.
- Capital letters are not allowed in subdomains.
- After submission, required checks can take up to 4 hours before the subdomain is ready for use.
Terminology
- Processing, Success, and Failed are the statuses a landing page subdomain can display during and after delegation.
- Do not confuse “delegating a subdomain” (making it available for use) with “undelegating a subdomain” (removing it from use).
FAQ
- Can I reuse a subdomain already delegated to Adobe for landing pages? Yes, as long as it is not already used as a landing page subdomain.
- What prefixes cannot be used? The
cdnanddataprefixes cannot be used, as they are reserved for internal use; thedmarcandspfprefixes should also be avoided. - How long does subdomain validation take? Required checks can take up to 4 hours after submission.
- Can I use multiple delegated subdomains of the same parent domain? No, but multi-level subdomains of an already-used parent domain are supported.
- What happens if I fail to create the validation record on my hosting solution? The subdomain is marked as Failed.
- How do I undelegate a landing page subdomain? Unpublish the associated landing pages, optionally delete the CNAME DNS record without deleting an original email subdomain, then reach out to your Adobe representative.
