p.s. About your postcard. Do you really want to advertise your detailing business the same as the dairy industry?
Understandably, the forum members are split on whether post cards are a good idea or not. I personally think any well thought out advertising is beneficial. Post cards are relatively low risk, there is not a substantial investment if you are willing to put sometime into it.
Attached is a mailer that I quickly threw together... (the upload tool forced me to shrink the file size).
A few general advertising tips:
Remember to keep some "white space"
Don't feel as though everything needs to be centered.
Fonts can help set a mood....but must be legible
The eye reads left to right , top to bottom.....keep that in mind...(pics attract the eye)
Headline and picture should match....
The job of the mailer is to make the phone ring....and interest the customer....
Your advertising should speak to your target market.
Sometimes use focusing on an end result or playing to pleasure vs. pain theory.
i.e. Winter is coming, is your car protected ????
Spend the day with the kids..... not the car.
Want your car to look brand new all over again???
Waxing your car has never been easier.
Did you know there are 1,237 pollutants that are attacking your car right now...... (# stat made up)
I don't really have anything specific to comment on since, you know your business better than i do.
Ask yourself....
Is it attractive?
Does the piece convey your business, brand etc..?
Does the piece easily provide contact info?
Does the piece speak to the target market?
Keep up the good work. Feel free to ask for any help or suggestions...
