Prevent fake DLR

In SMS marketing, a keyword is a unique term (it can include letters as well as numbers) that people text to your short code to join your list. For the best results, you want to choose a keyword that your customers can easily remember. You also want to select something that’s relevant to your brand. On top of your keyword opt-in strategy, it’s a great idea to have a sign-up form somewhere on your website where visitors can enter their details and subscribe directly to your SMS marketing.
