How can I disable double opt-in?
You can disable double opt-in in your campaign by choosing the desired campaign from the Your Current Campaign menu and then clicking on the settings wheel just to the right. This will bring you to campaign settings, then on the Permission tab is where you can control your enable or disable confirmed opt-in settings. Simply by checking or un-checking the boxes you’ll be able to control the settings for email subscriptions, web subscriptions and also import subscriptions. However, if you are using the API key in order to add contacts into your account you first need to contact our compliance team to ask them to be able to set this method to single opt-in. So all you need to do is contact us and we’ll be able to help you follow through with the steps needed in order to get that set to single opt-in.
