Resend
LiveInfrastructure by Resend, Inc.. Available now.
Transactional email: sign-in links, team invites, and a booking confirmation only when no calendar sent an invite.
How it works
What happens when Resend is connected
Sign-in links, team invites and the few emails Setupp sends about an account go through Resend, plus a booking confirmation when no calendar sent an invite. Recipient, subject and body pass through it to reach an inbox.
With no API key configured, every message is rendered in full and logged instead of sent, so nothing silently disappears while you are still setting up.
Data
What Setupp accesses
This is not something you connect. It is part of how Setupp runs, listed here because security reviewers are right to ask where the data goes.
No OAuth scopes. Setupp authenticates to this service with a server-side key that is never sent to a browser.
The full table, including what Setupp never does with any of it, is on the integrations overview.
