Where can I find my contact import rules so I can add or edit a rule
Can you share a little more detail in what it is that you are trying to change? There isn’t really a rule set for imports, but if you could share a little more detail, the community may be able to come up with a solution.
Rules for importing are not governed by users. You could call support and ask for a change if it’s available to do but you can’t change import rules that are set in your app on your own.
