Some subscribers are not active?

Inactive subscribers means that they have not confirmed their subscription request. In order for subscribers to begin receiving emails, they must click the confirmation link inside the email they receive when they request to be subscribed. This is a basic Opt-in feature that prevents random people from subscribing people without their permission.

Is there a way to resubmit the confirmation email to users that haven’t confirmed their subscription?

If the user resubscribes, OSD Subscribe will send them another confirmation email (it knows they have tried subscribing before). There is no way for an administrator to resend this confirmation email.

Thank you for the prompt response… Do you think this could be an option in the future?

We are no longer adding features to this plugin because sending emails from a WordPress install is considered bad practice. We have another plugin in OSD Subscribe’s place called “OSD Mailchimp Forms”. OSD Mailchimp Forms leverages free (or paid) mailchimp accounts to create/manage email subscriber lists and send newsletters.
