Musical acts and drink specials can change nightly, so keep your customers up to date on what's happening at your bar. Customers can sign up to receive text message alerts about what your bar is offering for the night. You should also offer exclusive text message promotions in order to draw more business. Text messages are an immediate way to connect with customers, as most text messages are read within five minutes of being received. If you want to pack your bar tonight, text message promotions are the way to go.
