SMS and Multichannel Marketing
Text messages open faster than email and carry their own rules, carrier registration, opt-in language, quiet hours, so these platforms are built around SMS and MMS first and layer email or push on top rather than the other way around. Pricing runs on message credits and phone number fees, and a few of these tools pair naturally with an email platform you already run elsewhere.
