I have a single opt-in list and want to add new subscribers and update existing subscribers.
Using the AddAndResubscribeWithCustomFields method I can do both, but when updating an active subscriber, they don't receive the confirmation email which new subscribers get sent.
The API documentation here, if I understand it correctly, says if it's not a double opt-in then the subscriber will be sent the confirmation email again (http://www.campaignmonitor.com/api/method/subscriber-add-and-resubscribe-with-custom-fields/).
I'm using VB.NET.
Please advise.... Thanks for your help.
