Honest, table-led comparisons. Every tool here is good at what it was built for · the question is what your day is actually made of. If it's deals moving through a pipeline, start with what an opportunity inbox is.
Both make email fast. Superhuman is the premium general-purpose inbox; OppBox keeps the speed and adds the deal on every email. If you're weighing the two for a revenue team, also read Superhuman for sales teams · what's missing.
The full field · deal-aware, collaborative, AI-first and budget options, compared by fit rather than feature count.
Salesforce Inbox is on its way out. What the official replacement path gives you, what it doesn't, and how to keep a deal-aware inbox on Gmail.
Streak turns Gmail into the CRM. OppBox does the inverse · your CRM stays Salesforce or HubSpot, and the inbox learns to read it.
Mixmax is sales engagement on Gmail · built to send more. OppBox is built to see deals · attention over activity.
Outreach is a sequencing platform for outbound volume. OppBox is an inbox for working the book you already have.
Not a comparison, a map · the four kinds of tool a rep can put on top of Gmail, what each is for, and what to look for before you pick one.
Fourteen days of Core, no card. Connect Gmail and your CRM and watch every email arrive wearing its deal.
