The most effective and standard method within Adobe Campaign to test that all variations of dynamic content display correctly is to send proofs. The proofing functionality is specifically designed to allow a practitioner to generate and send test versions of a delivery. When dynamic content is used, Adobe Campaign provides the capability to send a proof for each specific content variant, ensuring that every version can be reviewed in an actual email client before the main delivery is sent to the final target audience.

A. A content control group is a subset of the target audience that is intentionally excluded from the delivery to measure the campaign's impact and lift, not to test content rendering.

B. Content approval is a workflow process where a designated user must approve the delivery's content and parameters before it can be sent. It is a validation gate, not a tool for testing different content versions.

C. Including seeds sends a copy of the delivery to internal addresses simultaneously with the main send. A seed address will typically only receive one version of the dynamic content, not all possible variations for testing.

1. Adobe Campaign Classic v7 Documentation - Sending Proofs: "When your delivery contains several content variants

you can choose to send a proof of a specific variant

or proofs for all variants. This allows you to check each one of your content before sending the delivery to the main target." (See section: Send a proof > Content variants).

2. Adobe Campaign Classic v7 Documentation - Previewing Messages: "The preview lets you check the message personalization

the format (HTML and/or Text)

and the general message layout for a specific recipient. [...] For deliveries with dynamic content

you can preview each content." (This describes previewing as a validation step

which is complemented by sending proofs for a full end-to-end test). (See section: Preparing the send > Previewing messages).
