--- title: 'Meta Creative Testing with Paused Ad Copies' description: 'Reuse Meta ads with selected images or videos. Stage JPEG/PNG uploads, review proposals and verify paused copies before a separate governed resume.' canonical: 'https://plainrouter.com/product/launch' last_updated: '2026-10-03' --- # More Meta creative tests. Less setup. Stop rebuilding ads for every new creative. Reuse an existing Meta ad, choose your next image or video from the library, and submit the variant under Ask or Full. Build your next test without starting ad spend. Policy-allowed copies arrive in Meta paused, ready for you to inspect before activation. ## Give your next idea a faster start. Reuse the setup. Focus on the creative. ### Creative library Choose your next test with context. Inspect account-owned images and videos, associated source ads and the last 30 days of reported performance. Use that history as context for a test, not proof that a creative caused the result. ![Illustration of account-owned images and videos associated with a source ad.](https://cms.plainrouter.com/_emdash/api/media/file/01M4223GXA40HE7V1V68VXR3FK.png?v=fd856750adc65cf2c8b028d4491d5bccf7dc83673ad3b920656790f92ae905a8) - Images and videos together - Source ads connected - 30 days of performance ### Private asset staging Get new creative ready for review. Stage a JPEG or PNG privately and submit an upload proposal. Ask requires approval; Full can execute an allowed upload automatically. Wait for verified completion before selecting the new image from the Meta library. ![Illustration of a privately staged image waiting for upload-proposal review.](https://cms.plainrouter.com/_emdash/api/media/file/01M4223HXSH8JV5D41BQF9PV28.png?v=fd607afd123e97a99deb091971272f160c0f1ddbc30369ffcddcab68e2406306) - JPEG and PNG uploads - Private image storage - Reason for the test included ### Source ad reuse Skip the repetitive ad setup. Select an existing source ad and an image or video owned by the same Meta account. Reuse the source structure with the selected creative; this workflow does not create an arbitrary new campaign or audience. ![Illustration of an existing source ad paired with selected creative from the same account.](https://cms.plainrouter.com/_emdash/api/media/file/01M4223JPRGZZAMYJD0TJVXN8D.png?v=4982a653a29153106f0c3e37884f13358162b32173a1016d78383066bdf41170) - Source ad selected - Source structure reused - Creative swapped ### Reviewable proposals See each proposed variant clearly. Inspect the source ad, new creative, and reason for the test in one proposal. In Ask mode every change waits for your approval; in Full mode, changes that pass admission and workspace policy run automatically. Rule violations are blocked and shown in the Inbox. ![Illustration of a creative variant proposal showing its source, creative and approval state.](https://cms.plainrouter.com/_emdash/api/media/file/01M4223KMN1S3KJ0W50JE57M2W.png?v=27ed6ce4ac386b8e26f3ba5ab205375a0bc5dc06798f82b63ffbc78c064c6a7a) - Reviewable proposal - Evidence and rationale - Policy and mode ### Paused by default Prepare today. Activate when ready. Policy-allowed ad copies are created paused, so preparing a test does not start spend. A separate resume follows workspace policy. In Ask mode every change waits for your approval; in Full mode, changes that pass admission and workspace policy run automatically. ![Illustration of a new ad copy created paused with a separate policy-governed resume action.](https://cms.plainrouter.com/_emdash/api/media/file/01M4223MG0Q90JJK6Y9TAQPWBN.png?v=73d7f1682c322238e77e379aac97b1428b9370602783aca5c457997986a0a1bf) - Every duplicate paused - Resume follows Ask or Full policy - Paused state verified ### Verification & retries Finish with a confirmed ad copy. Inspect the receipt for the exact created ad, selected creative and initial paused state. Uncertain results are reconciled before retries; a failed or incomplete recovery remains visible for review. ![Illustration of uncertain provider results held for verification before retrying.](https://cms.plainrouter.com/_emdash/api/media/file/01M4223NDGCP7B7JRR12VS4V3J.png?v=1b17ae1686996ab69f927fe9bcc20028fc3262b66fb14bbe7e65b90bdbd75bfd) - Exact ad checked - Creative and state checked - Retries tied to the same request ## How Launch works ### Choose a source ad Browse Meta image and video assets with their source ads and recent performance context. ### Stage the next asset For a new image, submit a JPEG/PNG upload proposal and wait for verified Meta completion before selecting it for the variant. ### Prepare the variant Select a source ad and creative asset so Plainrouter can build the ad-copy proposal. ### Review through Actions Check the proposal and evidence against workspace policy. In Ask mode every change waits for your approval; in Full mode, changes that pass admission and workspace policy run automatically. ### Create paused and verify Create the policy-allowed duplicate paused, then verify the exact ad, selected creative, and delivery state. ## Launch FAQ ### Can Launch create an active ad? No. Launch creates ad copies paused and verifies their paused state. A separate resume can unpause one. In Ask mode every change waits for your approval; in Full mode, changes that pass admission and workspace policy run automatically. ### Which creative assets can Launch use? Launch reads images and videos in the selected Meta account and can reuse either in an ad copy. New uploads support JPEG and PNG images; new video uploads are not supported. ### Does Launch rebuild the entire campaign? No. Launch reuses a selected source ad with the creative you choose, saving you the work of rebuilding its structure. You decide what to test; performance depends on the creative and campaign. ### How do I know the intended ad was created? Plainrouter checks the created ad directly in Meta, including its ID, selected creative, and paused state. You can inspect the confirmed result; a separate resume can activate it under workspace policy. ### Do I need to upload every creative again? No. Select an existing image or video from the intended Meta account. For a new JPEG/PNG, submit an upload proposal first and wait for verified completion before selecting the asset for duplication. ### Can I prepare variants through MCP or the API? Yes. Use the creative-library, upload and duplication tools or the documented API with appropriate Write access. The requests create proposals; Ask requires approval and Full queues policy-allowed work automatically.
