It amazes me at the different schools of thought on this topic. Touch your clients 28 times a year, touch your clients 5 times a year, touch your clients 10 times a year. And on it goes.
So what is the right answer? Well it is two fold. If you do not have an updated database you won't be touching who you should. Check that out first before you sign up for anything.
You know your clients, you know how comfortable they are with receiving your mail. If you personalize it, if you make it fun, if you switch it up now and then. Try paper and email see the differences. Test market each,or custom email to those that like E Newsletters, and those that like print.
Realtors are bombarded with information everyday, remember you are the best person to decide how and when you are in touch with your clients.
Everyone is right in this scenario, in order to get the repeat and referral marketing stream of business you need to keep in touch with your current database.
Have wonderful day!
