Campaign overrides: which campaign wins
An override rule makes one campaign take a shopper who also qualifies for another, wherever the two sit in the start conditions order.

What a rule does
Without rules, the first campaign in the start conditions order that accepts a shopper takes them. A rule changes that last decision: when the shopper qualifies for both campaigns, the higher-priority one runs and the other is skipped. Qualifying means passing every check, so if the higher-priority campaign is paused, capped or refuses the shopper, the normal order stands.
Moving a campaign up the start conditions list often does the same job. A rule helps when one campaign should win whatever order the list ends up in.
Add a rule
- Open the campaign that should win, and go to Campaign overrides under Advanced.
- Choose Add override rule.
- Switch on Win over every other campaign, or leave it off and pick one under Campaign this one wins over.
- Choose Add rule. It applies at once, with no publish step. The bin icon on a row removes the rule.
The table shows rules where this campaign is on either side, so you can see or remove a rule from either campaign.
Where rules do not reach
- ACR compares only campaigns with the same event and lead source. The dialog lists every campaign, but a rule between a Shopify campaign and a Custom API campaign never fires.
- Rules do not chain. ACR replaces the first campaign once, with the first qualifying campaign that has a rule over it.
- Campaigns in an A/B test are left out of overrides.
- A lead you add by hand or import with a chosen campaign starts that campaign, whatever the rules say.
- Duplicating a campaign does not copy its rules.
