Once you have a warm contact list of interested prospects, what are the best ways of making sure your SMS campaign is successful? Probably the two best hooks you can use are an offer or discount code and rather than just supplying your telephone number, directly asking them to call you. In addition, always make sure that your message is clear and on a single subject: too many potentially good campaigns are scuppered by confusing details crammed into 160 characters. Talking of which, never use text speak – what may be acceptable in a message to a friend is never acceptable in business, however hip you think your campaign and your target audience may be. So remember: be clear, be concise and be proactive – the three golden rules of successful SMS marketing.
