Question: Installed and seems to work, but, it doesn't send the review reminder automatically. I've set the "Send Email After X Days" to "0" but nothing happens 


Answer: 

1/ Our module could help you email reminder review to customer after X day but your site needs to set up cron: 

You could see our logic of sending email on this file app/code/Bss/ReviewReminder/Cron/SendMailCron.php
2/ In email reminder, it contains order information, product name and go to review link + Please check our tutorial video here- https://drive.google.com/file/d/1lMx3NODk1e011q9ZH4zvvPdxGfDUJEXh/view?usp=drivesdk 
If you see the module couldn't send email even your site set up cronjob, please give us your site's credentials for further checking at sales@bsscommerce.com or via our ticket.
