The birthday gift module will send an email to the customer who has a birthday today, it can also create a discount voucher. You can set it to make vouchers or not, how much the voucher is worth, whether it's fixed or percentage value voucher, and the duration of the voucher. You can also set the prefix of the voucher code, and whether or not to send to all users, or just users with a valid order, and also set for which user groups will get the voucher/email. The module will log the emails sent, showing you stats on how many emails were sent, and how many vouchers used. This module works with eschiendorfer's Krona module.
thirty bees modules are open-source extensions to the thirty bees e-commerce solution. Everyone is welcome and even encouraged to contribute with their own improvements.
