Gravity4

Gravity4 is the world's first high-frequency machine-learning marketing OS, built to enhance the advertising and SaaS industries. The job it does: sending campaigns and automated emails to a list and measuring what gets opened.

The natural audience is marketers at companies of every size. Alongside the main category they mention Advertising, Advertising Platforms, Analytics, Email Marketing and Machine Learning. They are a mid-sized team, 201 to 500 people, which usually shapes who they work with.

Gravity4 is based in Miami, Florida and around since 2014. Their site is gravity4.com.

Things worth asking about: deliverability, list size pricing, and automation depth. A short pilot with your real data tells you more than any demo.

If you have worked with Gravity4, tell the next buyer what you paid and what surprised you. That is the part of this page we cannot write.
