Why does the newsletter subscription send multiple confirmation emails?

Hello,

it's by desing in Kentico. For each Newsletter the confirmation is sent.

You can clone the NewsletterSubscriptionWebPart and modify it in the function Save(..) to meet your requirements.

To disable the confirmation email you need to setup SendConfirmation and RequireOptIn to false.

                mSubscriptionService.Subscribe(subscriber.SubscriberID, newsletter.NewsletterID, new SubscribeSettings()
                { 
                    SendConfirmationEmail = SendConfirmationEmail,
                    RequireOptIn = true,
                    RemoveAlsoUnsubscriptionFromAllNewsletters = true,
                });

That will disable the confirmation altogether? How does this differ from the webpart setting "Send Confirmation Email"?

Thank You for your time.

Yes, it will disable the confirmation email for all newsletters, but you can put there your own logic.

Which version Kentico do you use ? I think this web part is obsolete.
