What works?!?!

Not sure what you are asking for?

E-mail, mailings, phone calls... Bekah, from what I have gathered talking with a lot of sales professionals, what helps isn't so much a particular type of "touch" so much as varying the "touches" and sending them consistently and systematically.  Quality, user-friendly customer relationship management (CRM) software will help you the most.  Once you've got that down, you can experiment more with what works best for you and your target client-base.  Good luck!
