Postales Magnéticas

Any type of business can use postcard magnets for direct mail marketing & advertising but there are certainly some that are ideal such as pizza delivery restaurants, service businesses like plumbers, roofers, landscapers, heating and air companies, cleaning services, pool companies, and restoration companies.
Another great use is for real estate agents who want to brand themselves in a neighborhood. You can mail a calendar with you photo and contact info on it or perhaps a list of local emergency phone numbers. Get creative there are lots of good ideas. The more useful it is the better chance of staying up where it can be seen.
Magnet postcards can really be done in any size that you normally mail.
