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.
Similar to email, SMS has anti-spam laws which differ from country to country. As a general rule, it’s important to obtain the recipient’s permission before sending any text message, especially an SMS marketing type of message. Permission can be obtained in a myriad of ways, including allowing prospects or customers to: tick a permission checkbox on a website, filling in a form, or getting a verbal agreement.[16]
I first got interested in mobile marketing when I saw how powerful it was to engage with my subscribers. I also could gather a huge list of leads on demand and order. ​Sending out text messages is a powerful way to talk and communicate with my prospects to make sale conversions. That's where it all begins with mobile marketing. This is a very profitable way to swiftly make money online

To avoid sharing numbers with other senders, and for brand recognition and number consistency, leasing a dedicated virtual number, which are also known as a long code or long number (international number format, e.g. +44 7624 805000 or US number format,[9] e.g. 757 772 8555), is a viable option. Unlike a shared number, it can receive SMS replies. Senders can choose from a list of available dedicated virtual numbers from a bulk SMS provider. Prices for dedicated virtual numbers can vary. Some numbers, often called Gold numbers, are more easy to recognise, and therefore more expensive to lease. Senders may also get creative and choose a vanity number. These numbers spell out a word using the keypad, like +1-(123)-ANUMBER.

This question exists for many. First, NEVER EVER purchase a list of mobile numbers. (SMS/MMS) marketing is permission based, and ultimately you want a list of customers numbers who are genuinely interested in your product or service and are happy to receive your text message and are likely to buy your goods and service. Remember, you can turn customers off and possibly upset a lot of your potential customers when sending text messages on their mobile devices without their consent.
