A newsletter that has many recipients has to be sent in stages. This process is managed by a queue.
You can access your queue by navigating from the dashboard to Newsletter >Newsletter Queue.
After you start the queue, your SITEBIZ website starts sending the emails in packs. To ensure the delivery of your newsletter, it's recommended to integrate your Sitebiz website with a third-party newsletter manager. MailChimp is highly recommended.
