Sendblue

Sendblue is built specifically for iMessage, Apple's native messaging app, and automatically falls back to RCS or SMS for Android users. This approach captures the premium experience on iOS while ensuring delivery to all devices. It's designed for brands that want to reach customers where they already message.

Sendblue works best for B2C brands targeting iPhone users, especially in North America. It offers a different value proposition than SMS-first platforms, prioritizing Apple's ecosystem before defaulting to standards.
