What GBrain can do with Resend

Resend is an email platform for developers that delivers transactional and marketing email. Connected to a workspace, GBrain can answer “did the password reset email to this customer go out?”, read the API logs behind a failed send, or draft a broadcast to a segment.

The tools cover the whole account, including domains, API keys and webhooks, and they can send email.

  • Send, schedule and look up emails
  • Read received emails and attachments
  • Manage contacts, segments and broadcasts
  • Set up domains, templates and webhooks

From the command line

GBrain gives Resend a command line too. From a terminal, a script or Claude Code, gbrainio tool help resend lists its commands once it is connected.
