1. Order Filters

Order filters decide which orders Postflows processes. If an order is blocked by an order filter, none of its shipping events will be forwarded to your email platform - regardless of which events are enabled. By default, with no filters configured, Postflows processes all orders.

When to use order filters

Order filters are useful when you want to:

Send notifications only to customers in specific countries
Exclude internal test orders or sample products
Limit notifications to specific product lines
Separate Ecomflow-fulfilled orders from standard orders

Filter types

Postflows has three order filter types.

Ecomflow Filter

The Ecomflow filter lets you include or exclude orders that are fulfilled by Ecomflow (a third-party logistics provider).

Note: This setting is only relevant for active Ecomflow clients.

Operator	Value	Behavior
`is`	`true`	Match only orders fulfilled by Ecomflow
`is`	`false`	Match only orders not fulfilled by Ecomflow

How this filter works:

When set to true (enabled): only Ecomflow-fulfilled orders sync to Postflows
When set to false or no filter is active: all orders sync to Postflows regardless of fulfillment source

Billing:

Ecomflow-fulfilled orders are free
Non-Ecomflow-fulfilled orders are billed at $0.035 per shipment

Country Filter

The Country filter lets you include or exclude orders based on the shipping destination country.

Operator	Behavior
`in`	Only process orders shipping to the listed countries
`not in`	Process all orders except those shipping to the listed countries

Use ISO 3166-1 alpha-2 country codes (e.g. US, GB, FR, DE, AU).

Example uses:

Only send notifications to customers in your primary markets
Exclude orders to countries where a local carrier handles communications directly

Items Filter

The Items filter lets you include or exclude orders based on the products they contain.

Operator	Behavior
`contains any`	Match orders that include at least one of the listed SKUs or Product IDs

You can enter product SKUs or Shopify Product IDs. An order matches if it contains any one of the listed items.

Example uses:

Exclude orders containing internal test or sample products
Only send notifications for orders containing specific product lines

Include vs. exclude mode

Every filter rule has a mode: include or exclude.

Include mode (whitelist)

At least one include rule must match for the order to be processed
If include rules exist and none match, the order is blocked
If you have no include rules, all orders pass this check

Exclude mode (blacklist)

If any exclude rule matches, the order is blocked immediately
Exclude rules always take priority over include rules

No rules

All orders pass through

Example: Include rule Country in [US, CA] + exclude rule Items contains any [TEST-SKU]:
US order, regular product: passes (matches include, doesn't match exclude)
CA order with TEST-SKU: blocked (matches exclude - exclude wins)
UK order, regular product: blocked (no include rule matches)

Editing filters

Each filter type is configured inline: toggle it on or off, adjust its settings, then click Save.

Changes take effect immediately for new events. Existing orders in progress are not re-evaluated.
