# Combining Segments

Advanced customer segments can be created by combining two existing segments. This enables a more specific way of targeting by merging, intersecting, or comparing different customer groups.

1. In the [**Admin Portal**](https://admin.gobossit.com/), go to the **group level.**
2. Click on **Marketing.**
3. Navigate to **Segments**.
4. Click **New from Combine.**
5. Select **Segment A** and **Segment B** from your existing segments.
6. Choose the required operation to combine them.
7. Click **Continue** to generate the combined segment.

## Operation Types

### Union (A ∪ B)

Combines both segments. Includes customers who appear in Segment A, Segment B, or both.

> **Example:**
>
> **Campaign:** Brunch Menu Product Launch Campaign
>
> **Segment A:** Breakfast Customers - Customers who have ordered during breakfast time ranges.
>
> **Segment B:** Lunch Customers - Customers who have ordered during lunch time ranges.
>
> \
> Combining the segments through a union will give a list of customers who have ordered during either breakfast or lunch (or both). This combined segment can then be used to promote the brunch menu.

### Intersection (A ∩ B)

Finds common customers. Includes only customers who appear in both Segment A and Segment B.

> **Example:**
>
> **Campaign:** Lapsed VIP Customer Re-engagement Campaign
>
> **Segment A:** High Points - Customers with 1000+ loyalty points
>
> **Segment B:** Inactive Customers - Customers who haven't ordered in 30 days
>
> Getting the intersection of these segments would result to a list of customers who have high points but have stopped ordering. This combined segment can then be used in the campaign.

### Difference (A \ B)

Excludes Segment B from Segment A. Includes customers who appear in Segment A but not in Segment B.

> **Example:**
>
> **Campaign:** "We Miss You" Win-Back Campaign
>
> **Segment A:** Regulars - Customers with 5+ orders
>
> **Segment B:** Recently Active - Customers whose last order was in the past 60+ days
>
> Combining the segments by getting the difference of the segments will result to a list of customers who ordered frequently but haven't ordered recently. This combined segment can then be used to in the campaign.

### Difference (B \ A)

Excludes Segment A from Segment B. Includes customers who appear in Segment B but not in Segment A.

> **Example:**
>
> **Campaign:** Product Cross-Sell
>
> **Segment A:** Pizza Buyers - Customers who have ordered pizza products
>
> **Segment B:** Recently Active - Customers whose last order was in the past 30 days
>
> Combining these segment by getting the difference of the segments will result to a list of recently active customers who have never ordered pizza. This combined segment can then be used to promote the pizza menu.
