5\. Save, Attribuly starts to sync the segment to Meta.

## Tips

1\. Changes to the customer list in the Attribuly segment will also be synced to Meta Custom Audience, but this change will not allow your ads to re-enter the learning phase.

2\. Meta requires a minimum of 100 profiles to create a custom audience.

3\. The Customer list uploaded by Attribuly has a value, and the value is based on the customer's past purchase records. This makes it easier for the Meta algorithm to understand your customer value.
