Hi @vmpetsmart,
Unfortunately, there’s no option to bulk-resend the confirmation email to all “Unconfirmed” subscribers. That would be a big risk if you had a high number of “Unconfirmed” subscribers with invalid email addresses (or from fake signups, for example), as all of the confirmation emails would bounce back and affect your deliverability and your account.
The important thing here is to find out why you have so many “Unconfirmed” subscribers in the first place. Is this because the sending was not working when they signed up? Could these be fake signups coming from an unprotected form on your website? Or maybe these people changed their mind about subscribing and decided not to confirm their subscription?
