Email marketing options for Vacation Rentals

[Joe Garvin]

Hello,

We are researching what the best options for doing some email marketing to past customers.  We capture everyone's email address with in Quickbooks and want to send out monthly emails with specials to try and encourage repeat customers.  I've used Constant Contact in the past and like they generate matrix for Open Rate and such which is useful.  Are the other services folks have used that has been successful and lower cost?

Thanks in advance everyone!
