Hello RacoonCiryHost,
If you need mass mailing functions, for example, to send your company's news to your customers, you should use BILLmanager Corporate. BILLmanager Standard delivers limited functionality and doesn't have such options.
You can install
a free version of BILLmanager Corporate and create up to 50 clients. It provides a large number of functions, including different marketing tools, such as mass mailing, discounts and promo codes, and
much more.
