SMS Marketing Vs Email Marketing: Which Drive Better Result?

What is SMS Marketing and how does it work?
SMS stands for Short Message Service. Meanwhile, SMS marketing is a digital marketing strategy that follows the process of sending text messages directly to mobile users, which doesn’t require an internet connection. Messages include promotions, updates, alerts, etc.
Messages can be of various types: Promotional, Transactional, or Reminders. Promotional messages include the mass texts sent to a group of clients regarding flash sales, coupons, product arrivals, etc. On the other hand, transactional messages are more personalized automated texts sent based on specific customer behavior, like past purchases, order confirmation, shipping, etc.
You initially start by collecting the number of previous or potential clients who gave consent to receive messages. Marketers generally use specialized SMS marketing software instead of standard phones. This software enables businesses to automate campaigns, schedule bulk texts, and personalize messages. The messages are generally short, concise, and focused, but in less than 160 characters & features a clear CTA (Call-To-Action).
