From ads to drip campaigns, brands are using messenger apps to better connect with their users.

With record-breaking engagement (up to 80%!) on messenger apps, it's no wonder.

But not all messenger apps are created equally.

WhatsApp is has the most users worldwide, but Facebook Messenger dominates the U.S. market.

But in some countries, neither Facebook Messenger or WhatsApp are even available.  
It's important to pay attention to the top messenger apps throughout the world, especially if you have an audience in other countries.

To that end, let's explore the top 7 messenger apps in the world!

1. WhatsApp

WhatsApp is the most preferred messenger app in the world today.
