New emails come to our system from various sources:

• email collectors or intelligent site collector;
• manual input of emails from users;
• import users within dashboard;
• through the API

By default, new emails do not get any extra information or subscription status, if you do not pass those attributes along with the emails.

If you want to automatically subscribe new email recipients with isSubscribed and isSubscribedAlerts set to true, you can do it from this page. Note that you are the only responsible to acquire subscription confirmation for those that you are sending emails to.

Default values for user attributes can be set under Users > Optin

How default values work when Double Optin is enabled?

If you have DOI enabled, regardless of you default attributes the following are set:

• isSubscribed = False
• isSubscribedAlerts = False

They become true when the recipient clicks on the link inside the confirmation email to confirm the subscription.
