Hello!
How far the the mail going back?
Customer in .... 2016 can Get also a mail?
Well, it's possible but needs lots of work from you.
You can create the reminder with the delay before sending like 3, 4, 5 or 10 days.
The add-on will check what add-ons get the specific order status 10 days ago, for example, and sends the message to these customers. Not to those who changed order status 8 days ago, not to those who changed order status 15 days ago. only 10 days, or any other number of days specified in the reminder settings.
So, if you want to ask fro a review from customers of 2016. you need to set up one reminder with the delay 150 days, for example. In this case, you will send a reminder to those who place order exactly 150 days ago.
Best regards,
