A good CRM, Customer Relations Management system gives you the capability to send out helpful information and correspondence to your clients in a Drip Campaign (an automatic email & text messaging system). Using the CRM for reminders and contacts is extremely useful as well. CRM's range in prices from no cost at all to healthy monthly fees. It's up to you to see where a CRM will fit into your budget. If you are not using a CRM you are behind the times in relation to just about every successful Realtor.
