Your stack, connected.
Tantra sends from your Google Workspace, writes with your own AI key, syncs your webinar platform, and emits every event to your automation tool. Here is everything it connects to and what each connection actually does.
Where your mail comes from
Google Workspace
AvailableUpload a service account, have your admin authorize it once, and every mailbox on your domain becomes a sender for both email and calendar invites. Tantra never holds a password or a personal OAuth token.
Custom tracking domains
AvailableServe click tracking from a CNAME on your own domain, so every link in your emails carries your name rather than a shared tracker.
Microsoft Calendar
Coming soonOAuth connection for Outlook calendar users, as an alternative to Google Workspace.
From invite to attendance
Zoom Webinars
AvailableSync webinars, registrants, and attendance with watch time from a Server to Server OAuth app you create in your own Zoom account. Recurring webinars sync per occurrence, and registrants export to CSV.
WebinarGeek
AvailableSync broadcasts and subscribers, register RSVP positive contacts automatically, and see attendance next to your Zoom webinars in the same report.
Your key, your model
LLM providers
AvailableOpenRouter, Cerebras, and Novita. Your key, your model, your system prompt. You pay your provider directly, so there are no AI credits to buy from us and no markup on inference.
MCP server
AvailableThirteen tools that let Claude, Claude Code, or Cursor drive Tantra in plain language: list campaigns, import contacts, check stats, start a send.
Everything else downstream
Webhooks with n8n, Zapier, and Make
AvailableTyped events POST to any endpoint the moment something happens, with retry and deduplication. Wire them into your automation tool to update the CRM, alert Slack, or run anything downstream.
REST API with scoped keys
AvailableIssue keys scoped to exactly what an integration needs across campaigns, contacts, and webhooks. Revoke one without touching the rest.
Invite. RSVP. Registered. Attended.
Webinar outreach usually dies in a spreadsheet. You export the invite list, import it into Zoom, hope the join links go out, then guess who came because of you. Tantra closes that loop. A contact accepts your calendar invite, Tantra registers them into the linked webinar, and Zoom sends them the join link. After the session, sync attendance and the report answers the only question that matters: of the people you invited, how many showed up.
Automatic registration
An RSVP of yes or maybe triggers registration into the linked webinar a few minutes later, backed by a queue with recovery, so nobody falls through.
Attributed attendees
Reports unify Zoom and WebinarGeek and show attendance with watch time for the people your campaign invited, separately from everyone who found the webinar some other way.
Your Zoom, your data
You create the app in your own Zoom account and paste the credentials. Syncs run when you trigger them, and the client secret is encrypted and never shown again.
The integrations we did not build are covered too. Every event Tantra emits can reach any tool through webhooks, so this page is the floor rather than the ceiling.
