There is a 160 character limit on text messages. With SMS, it’s simply about providing an irresistible offer. There’s no point in droning on and on with a 300-word marketing message. Subscribers are opting in to receive an exclusive offer, not to hear about how your day is going. Our current digital age rewards simple marketing messages with easy to understand calls to action. The 160 character limit on SMS messages is actually ideal.
You will have a greater chance of gaining access to their mobile number by following these guidelines. You can collect their numbers using a sign-up sheet at your register, asking them when talking on the phone, allowing them to submit a form on your website, or by giving them a number that they can text to subscribe to your SMS messages. Whatever you do, keep a copy of their permission to market to them via SMS, if you run into problems you will be glad you did.
