OppBox is a full mail client for your Gmail · read, compose, reply, snooze, schedule, search · with one difference that changes everything: every thread knows the deal it belongs to. Open an email and the opportunity is right there, account, stage, value, last real reply and the signals that say healthy or ghosting. Your mailbox never moves; it just finally knows what it's worth.
Every opportunity email is banded and labelled with the deal it belongs to, pulled live from Salesforce. No tab-switching to remember what a thread is worth · the CRM is rendered where you already read.
A time-sorted inbox has no row for "your biggest deal went quiet nine days ago." OppBox computes that and surfaces it · so the deals you'd otherwise forget to fight are the ones you see first.
Ask for a reply draft, a deal brief or a follow-up and Claude writes it from your real threads, signals and meetings. You review, edit and send from your own Gmail address. Nothing leaves your hands unseen.
Use your existing Google account through WorkOS. No new password, no separate OppBox login to remember.
Approve the minimal mail scopes on OppBox's own Google consent screen. OppBox stores a per-mailbox token, never your password.
One more OAuth and your pipeline fuses onto the inbox. That's the whole setup · two consents, and your Gmail is deal-aware.
Your email is the most sensitive thing you'd hand a tool, so the access path is the part we over-engineer. OppBox reaches Gmail only through enterprise email infrastructure that holds Google's restricted-scope security verification · and OppBox carries its own Google verification and annual CASA security assessment on top of that.
We ask for the minimum scopes a mail client needs and nothing speculative. Adding a scope is a Google re-review and a fresh consent from you, never a silent expansion. Revoke any time in one click, from OppBox or from your Google account.
OppBox doesn't copy your Gmail into another database. It reads your mailbox live and renders it, so your labels, threads and history stay exactly where they are. Stop using OppBox tomorrow and not one email has moved.
A rep on OppBox and a colleague on plain Gmail are working the same mailboxes. Replies, sent mail and threads sync through Google as they always did · OppBox is a better window, not a walled garden.
Mail is an interface inside OppBox, with one implementation today (Gmail) and Outlook on the bench · the same email infrastructure speaks Microsoft natively, so it's a switch we flip, not a rebuild. Your muscle memory survives a stack change. See the roadmap.
Two consents and your inbox knows every account, stage, value and silence · without leaving the mail you already live in.
