Magento Order Reminder extension helps increase sales by marketing to existing customers who have not ordered from your store in a while. It is almost always cheaper to market to your existing customers than to try and acquire new customers. Magento Order Reminder extension will e-mail customers who have not ordered in a while and encourage them to make a new purchase. You can setup multiple reminders / follow up intervals and you can even include a automatically generated coupon in the reminder to incentivize the purchase.
For example, you can email customers who have not ordered in the last 3 months. At month 4, if they still have not ordered, you can send them another follow up that includes a coupon to further encourage them to make a purchase.
