An Individual in our Data Cloud has multiple Contact Point Emails for example 2 private emails, 1 business email. When we build an activation, we need to reach all of these email addresses separately, not just one.
The problem: in the activation setup, the Contact Point Email section has "Max # of Attribute Values" locked to 1. Even when we use a custom DMO on a file-based activation, we can increase this number, but the output is still one row per Individual with multiple emails packed into the same row (as extra columns or JSON). Marketing Cloud cannot process this we need one row per Contact Point, not one row per Individual.
Salesforce Support confirmed that this fan-out format is not natively supported by the activation engine.
Has anyone found a way to activate all Contact Points per Individual as separate rows?

Here is what you can try:
1. Build a custom DLO/DMO that's a
bridge/fan-out table: one row per (Individual, Contact Point Email) pair — basically your Contact Point Email DMO reshaped as an engagement-style child object, related many-to-one back to Individual.2. Instead of segmenting on Individual or Unified Individual, set "Segment On" to that fan-out DMO.
3. Now every row in your segment membership is a contact point, not a person — so when you activate, the output has one row per email address.
4. Use an Activation Template here, since it lets you tie the specific contact point to the record without invoking identity resolution at all. With Activation Templates, the Contact Point to use is tied to the Individual or Engagement record, without any Identity Resolution needed.
I haven't run this exact "3 emails per individual" scenario end-to-end myself yet, so treat it as an architecture direction to prototype rather than a guaranteed fix.
