How to increase direct bookings through marketing emails

[Pablo Flores]

Hey all,

    Is there some service that will automatically send marketing emails to previous guests? Im looking for ways to increase direct bookings through our website. We're nearing close to 3000 nights booked for the year, and have all emails/ phone numbers for previous guests saved through our property management software. How do i best use that information to send periodic marketing emails to get guests to rebook via our website?
