Bulletproof Inbox

Bulletproof Inbox provides email screening software that blocks spam, phishing, and unwanted messages for Gmail and Outlook users. 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 Email and Email Marketing. They are a very small team, 1 to 10 people, which usually shapes who they work with. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

Bulletproof Inbox is based in Austin, Texas. More on bulletproofinbox.com.
