Big brands yes.. but not so much in the SME market (although we do have 60,000 UK business customers... many are SMEs in every sector...)
Imagine a Fish & Chip shop. They ask their customers to join their "text club" by texting FISH to 60777. Over a short time they grow an OPT IN list of people who CHOOSE to receive messages on their handset.
The owner can then send a message to 100 people for around £4... in an instant - directly into the palm of their hand. "Come to our shop tonight with the code xxx7 and get a free bottle of coke with any order!"...
Quite simply the most cost effective way to generate repeat business available!
NOT SPAM. NOT INTRUSIVE. NOT TECHNICAL!
