What I have done before now is look up a well known internet telephone directory, look say for Dentist in your area copy and paste email addresses collate a list make an email up that personalised it from you to a dentist and send a block email keep the list on outlook and mail them out once a month or so, keep lists for doctors surgeries all sorts, its time consuming to build your lists but once you have them the rest is easy I have only targeted Dentists about 15 to 20 and secured one from it so it does work. I just don't have the staff for night jobs and can't get staff to do them, so it’s on hold for me right now regards Phil
