You and I both know it would be! Well, the SOLUTION is to put automated information between YOU and your PROSPECT. So lets do the same voice broadcast or ringless voice drop to 1,000 prospects on a Tuesday afternoon but this time around, you use your (NEW) sms mobile number as a "buffer" between YOU and the PROSPECT. In other words, they have to go through your phone marketing system BEFORE they can get a chance to talk to you.
This allows people to text a custom keyword to a dedicated virtual number or shortcode. Through custom keywords, users can opt-in to a service with minimal effort. Once a keyword is triggered, an autoresponder can be set to guide the user to the next step. They can also activate different functions, which include entering a contest, forwarding to an email or mobile number, group chat, and sending an auto response.
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.
