How do you market your cakes with retaurants, cafe's, party planners etc. to do business with them.
In person, e-mail or letter ?
Go to a restaurant between the hours of 2pm to 3pm only, Monday through Wednesday. Have a business card and possibly an introduction short note. Ask to see who is in charge of ____. Hand the person your packet and ask for an appointment to discuss your offerings. He/she will tell you right then if they are interested. Make an appointment in an appointment book and tell the person you will send an email the day before to make sure the appointment time is still convenient. If they say maybe later, ask permission to contact him in ___ weeks. For party planners, an intro email about your company with a date that you will call to set up a time to see them.
You can add a cupcake in an individual box, or something like that, but don't overwhelm or make them seem obligated to talk to you because you brought a large sampling. For those who do make an appointment and confirm, another sample would be a nice gesture.
I agree with scp1127, that is the best way. They get to see you in person and see your personality.
Personally I like communicating through email so I would try that first since that is my style (although not the most effective method ).
This info comes from my old days of selling Yellow Pages on full commission in the 90's. I would suggest to anyone wanting to expand their business to go to amazon and look up the top rated sales and marketing books. They are a wealth of information. Sometimes business owners don't see that "salesman" is one of the hats to wear.
