Sending a single review invitation (manual)
This is the best option to use if you are sending a small amount of review invitations, such as up to 100 per month. You will be manually selecting which template and subject line to use, along with each customer name and email address.
Click Review Requests in the left hand menu of your dashboard, then select My Requests. In the top right corner click New Review Request, which is where you will be able to fill in your details and click Send Review Request.
