Hello @SaralyP ,
We don't have any official integration we've developed with an app called "Setmore." You may be able to find a 3rd-party developed integration that can sync contacts between the systems, by searching online. Otherwise, we generally recommend exporting the contacts as a CSV file from the source you're trying to pull from, and import that file into your Constant Contact account.
