Priced per company. Not per inbox.
Most cold email tools bill for every sending address and every seat, so the tool gets more expensive exactly as it starts working. One price here, both engines, as many mailboxes as you own.
Set up your account, connect a mailbox, and look around before you pay anything.

What we never charge extra for.
Sending mailboxes
Connect every Google Workspace mailbox you own. There is no per inbox charge and no seat count.
Contacts
Import as many contacts as you have. No list size tier, no overage bill when a list grows.
Campaigns and sequences
Run as many campaigns, sequences, and steps as you need, across both engines at once.
Calendar invitations
Calendar campaigns are not counted separately or billed per invite.
AI inference
You connect your own OpenRouter, Cerebras, or Novita key and pay them directly. We add no markup and sell no credits.
Both engines
Cold email and calendar outreach are one product. You do not buy them separately.
The one limit we do not set: Google Workspace allows up to 1500 recipients per mailbox per day. Tantra holds every mailbox under that ceiling. Adding more mailboxes raises your headroom, and it costs nothing.
