If you import contacts that are already in Simio, these contacts will be automatically deduplicated so that you don’t have the same contact twice in your database.

You can re-import a database with the same contacts if you want to add a custom field to your contacts (for example, a birthday). Contacts already present in Simio will be updated with the new custom field.

A 'never opt-in' user is a contact who has not opted in to receive your communications. However, they may have received a message from you as part of a Utility-type automation (for example: order confirmation). Utility messages do not require an opt-in to be sent.

If you want to convert these users into opt-ins, we recommend adding an option at the end of your Utility flow to offer subscription to these users.
