You are always thankful for all of the work and services provided by the vendors during your wedding. Everyone from the venue staff to the hairdresser puts so much effort into making sure you are happy on your wedding day. One of the simplest things you can do to thank them is review them. This could be on their site, Yelp, and also by word of mouth. Knowing how much they put in for you, its the least you can do for them.
