When comparing SMS and email, SMS has many advantages when it comes to speed, accuracy of delivery, engagement and open rates. Another primary benefit of SMS is that most people worldwide own a mobile phone (billions) and almost of those phones are always in reach.
Many e-mails automatically end up in the trash or spam folder, and inboxes often quickly fill up with e-mails that just never get seen. In comparison a SMS message is typically read within the first few minutes of receipt, by over 90% of the recipients. That includes Person-to-Person (or P2P) as well as Application-to-Person (or A2P). To reach consumers and encourage them to engage, businesses are increasingly turning to mobile messaging as their primary channel.
