Include the clients' name
Thank them for their time
Let them know how long it will take to complete
Mention the importance of reviews for your business
Wish them luck in the future
Reassure them that you are there to assist in any future endeavours
Keep it short and sweet and straight to the point
Forget to let your vendor know their review is important to you - if you don't tell them they may not take the time to write one
Forget to send a review request from your dashboard - with RateMyAgent, you're in control of who can review you - without a link, your vendors and buyers can't leave feedback - even if they want to.
Leave it too long to ask for a review. Make requesting reviews a part of your weekly admin, on a Monday morning, for example, to chase up those weekend sales. Make it a habit.
Forget that you can personalise the email that goes with your review request, why not add something personal to the vendor.
