Choosing the right communication channel to boost customer engagement has become a top priority for businesses across all industries. According to the 2015 study by Salesforce, 46% of marketers are using some kind of mobile marketing – either SMS, push notifications, apps or location-based services.

Mobile remains a popular channel of choice and it doesn’t take much guessing to understand why. By 2020, the number of smartphone users worldwide is expected to reach 6.1 billion. The rapid increase in mobile phone use gives marketers a chance to increase loyalty and expand their client base by interacting with customers through the channel they prefer.

Comtrade messaging services can help you harness the potential of mobile and reach more customers quicker by sending a variety of information with complete automation and maximum security.
