Mailchimp sends to confirm your subscription. How to disable?

Hello!
Daily using the service Mailchimp (via API) we will arrange the delivery of notifications on the day of birth for our employees.
The mechanism works as follows: the script generates a list of e-mail addresses of employees of the organization and updates the mailing list. Next, create a campaign and running the newsletter for the updated list. The sheet is always the same.
3 campaigns were successful and subsequently all the addresses were unsubscribed to the post office and the employees began to come daily emails asking you to confirm the mailing, although some have confirmed. How to disable confirmation mailing? Has anyone faced with such a situation?

you need to change the type of bulk that "after registration, password reminder", etc., forgot the name
Sorry, found no such settings. But after the first 3 campaigns were successful, and the change in the script and newly created mailing lists, no one did.. - Brandy_Parker commented on July 9th 19 at 10:30
