A custom sender ID, also known as an alphanumeric sender ID, enables users to set a business name as the sender ID for one way organisation-to-consumer messages. This is only supported in certain countries and are up to 11 characters long, and support uppercase and lowercase ASCII letters and digits 0-9. Senders aren’t allowed to use digits only as this would mimic a shortcode or virtual number that they don’t have access to. Reputable bulk SMS providers will check customer sender IDs beforehand to make sure senders are not misusing or abusing them.
Don’t forget to include your SMS marketing campaign as part of your overall marketing plan. Place a call to action on all of your marketing products, print and digital, inviting customers to join your SMS circle by texting a message or code to your phone number (in exchange for a discount, freebie, or other reward). This will help to broaden your customer base as well as increasing sales.
