  • Created and every time it's edited: Evaluates the rule criteria each time a record is created or updated If the rule criteria are met, run the rule.
  • With this option, the rule repeatedly runs every time a record is edited as long as the record meets the rule criteria.
  • Note: If you select this option, you can't add time-dependent actions to the rule.
  • Created and any time it's edited to subsequently meet criteria: (default) Evaluate the rule criteria each time a record is created or updated.
  • For a new record, run the rule if the rule criteria are met.
  • For an updated record, run the rule only if the record is changed from not meeting.
  • With this option, the rule can run multiple times per record, but it won't run when the record edits are unrelated to the rule criteria.
