Well, this is good Email would really make impact to your case for BOWP, but such one liner would not be good. Please have Email "like" below and make sure few people (like Senior Manager/ Client Manager) are copied so that it wont look like created specially for this purpose.

==============================
Also, don't submit your application on the same day you get Email. Wait for some 8/10 days and then submit the application. Also, you need very good explanation letter to support this and also good blessing from your friends
. If you have offer letter from other company, that would also make impact although not 100% required.
