Works with the stack you already run.
Outbound Labs is the engine in the middle. Data comes in through provider APIs; meetings and deals go out to your tools.
Mailboxes
Google Workspace, Microsoft 365, any SMTP/IMAP inbox, or our pre-warmed sending domains.
Contact data
Inbound Labs API and other B2B data providers through their APIs. Billed by the provider, on your own account.
Profile visits, connection requests and messages inside sequences, with per-account daily limits.
Calls
Aircall, JustCall, Dialpad or your own dialer. Call tasks out, outcomes back.
Calendars
Google Calendar, Outlook and Calendly for booking and availability.
CRM
HubSpot, Salesforce and Pipedrive. Contacts, activity and meetings synced both ways.
Approvals
Slack, email and WhatsApp for approval cards and alerts.
Everything else
Webhooks and a REST API for anything not on this list.
