I recently sent out an email to our customers about a contest we’re running at the moment.
The goal?
To get as many positive reviews as possible on the 3 sites that are likely to bring us the most cold traffic going forward.
It took me awhile to figure out how to properly incentivize our current customers to leave reviews on ALL 3 sites but I think I came up with a good scheme to make it happen.
What do you think?
The email:
Subj: Want to win a free year on ZenMaid?
Body:
Hey %firstname%
I’d wanted to give you a heads up that we’re running a quick contest here at ZenMaid with the winner receiving 1 year FREE on our ZenMaid

All you have to do for a chance to win is leave us a review on at least 1 of the following 3 sites:
We know it can take a few minutes to do each so we wanted to incentivize you to leave us a great review on all 3 platforms.
Here’s how it works:
If you leave us a review on 1 of the sites, we’ll enter you ONE time in the contest
If you leave us a review on 2 of the sites, we’ll enter you THREE times in the contest
If you leave us a review on all 3 sites, we’ll enter you NINE times in the contest
This means that your chance of winning is almost 10x better if you leave us a review on all 3.
All you have to do is leave us reviews here:
This contest ends September 15, 2015. I’ll send a few reminders before then.
Like always, please let me know how I can assist you and your business even more

Cheers!
Amar
