It works inside what you already use
OppStream sends from your address, writes to your CRM and reads your calendar. It is not another inbox to check or another list to keep up to date.
- Your mailbox
- Gmail or Outlook, your domain, your threads
- Your CRM
- Salesforce and HubSpot, kept in step both ways
- Your calendar
- real availability, not a booking link
Connected today
Gmail
Send from your own address, in your own thread. Replies are read back so the sequence knows to stop.
Outlook
The same, for Microsoft 365. Drafts land in your mailbox if you would rather send them yourself.
Salesforce
Accounts and contacts flow both ways, so the CRM stays the system of record and OppStream stays out of the way.
HubSpot
The same two-way sync, for teams running HubSpot instead.
Bring in the people you already know, so outreach can open on a shared contact instead of a press release.
Google Calendar
Meeting slots proposed in replies come from your real availability and your working hours.
What it does not do
Two things worth saying plainly, because most tools in this category do the opposite.
It does not send from a shared domain
Everything goes out from your own mailbox and your own domain. Your deliverability stays yours rather than being pooled with strangers.
It does not become the system of record
Your CRM stays authoritative. OppStream researches, drafts and tracks — and hands the result back rather than holding it hostage.
Every item here is connected and working today. There is no “coming soon” section, because an integrations page is the one page a reader can verify in thirty seconds — and a single thing that turns out not to exist puts every other claim on the site in doubt.
