Integrations · Outreach channels
Run Gmail and Google Calendar outreach from your own Workspace.
Gmail steps and Calendar invitations send from your team's own Workspace mailboxes. A Workspace admin authorizes one service account with domain-wide delegation once; you then verify each mailbox that will send.
Requires a Google Workspace super administrator.
What you get
One admin authorization
Upload service-account JSON and authorize the required scopes once at the domain level.
Multiple sender mailboxes
Verify and manage mailboxes without collecting each sender's password.
Calendar and Gmail capability
Each mailbox is shown as calendar-capable, Gmail-capable, or both.
Your sender identity
Messages and invitations are sent from your own Workspace mailboxes.
Sender controls
Manage sender verification, connection state, signatures, and separate limits for each channel.

Create a service account in a Google Cloud project
- 2

- 3

Supported actions and data
Tantra can do
- Send threaded Gmail steps as part of a sequence
- Create Calendar events and send Google Calendar invitations
- Detect replies, clicks (when enabled), bounces, and unsubscribes
Tantra receives
- RSVP Yes, No, or Maybe from calendar invitees
- Inbound Gmail replies and bounce notifications
Requirements and permissions
A Google Workspace super administrator
Needed once, to authorize the service account in the Google Admin console
A service account in a Google Cloud project
Its JSON key file is uploaded to Tantra
Domain-wide delegation for the required scopes
Gmail scopes for Gmail steps, the Calendar scope for Calendar invitations
Verified sender mailboxes on the authorized domain
Each mailbox is verified in Tantra before it can send
Scope and limits
- Gmail and Calendar capability checks are separate; a mailbox can be one, both, or neither.
- Calendar invitation campaigns and sequences are separate campaign paths.
- Sending requires a Google Workspace domain; consumer Gmail accounts cannot send through Tantra.
- Google Workspace is required only for Calendar campaigns or sequences containing Gmail steps. A social-only sequence does not need it.
