SMS Keywords


SMS Keywords are words that people text to either a 5-6 digit number (Short Code) or 10 digit number (Long Code) using their mobile phone, or other device. These SMS Keywords are used to interact with your business through a dedicated phone number that corresponds to a specific text messaging campaign.
Messages can be sent and received through these short or long codes and all messages are stored for later use. You can use CryptoKeywords to send reminders, birthday wishes, set appointments, mass messaging campaigns, discount coupons, reservation notifications, RX refill messages, advertise your business, sell a house, and much more. Easily send SMS messages through our API integration, FTPS, or through our web interface. The possibilities are endless.
