Resend (email)

Send emails from your own domain during calls using your Resend  account — confirmations, summaries, callback requests, anything you’d want in a customer’s or your own inbox.

This differs from the built-in Send email tool: the built-in tool mails a fixed recipient (you); the Resend integration sends from your domain to addresses the conversation calls for, under your Resend account.

Setup

1. In Resend, verify your sending domain and create an API key.
2. Integrations → Add integration → Resend.
3. Set the From address — e.g. Reservas <reservas@yourdomain.com>. It must be on a domain verified in your Resend account.
4. Paste the Resend API key. It’s stored encrypted and never shown again.
5. Click Add & discover tools.

Tools

• …_send_email — compose and send an email (the agent writes recipient, subject, and body; the from address is fixed to what you configured).

Enable it per agent version in the builder’s Integration tools card, and tell the agent in its instructions when sending email is appropriate (e.g. “after booking, offer to email a confirmation”).
