I have added contact from c# api but those contact are not getting confirmation email.

WE have tried EmailService.Optin method but it’s not working.
Please suggest.

Hi @Justin_Lam, calling APEmailService.optIn will only change a contact’s status to Unconfirmed and does not send out a confirmation email. You could automate the sending of the confirmation email by setting up a campaign to that sends the email and use the API goal and FunnelService.achieveGoal to add the contact to that campaign.
