Get started
Connect Resend and give a brand its support address.
All mail goes through one Resend team, connected by OAuth from setup. An installation set up from a file, with
no browser to approve that in, uses a Resend API key in RESEND_API_KEY instead
(Automated install). During setup, the email step walks through:
- Connect Resend. You approve Bouée in Resend and come back to
APP_URL/api/resend/oauth/callback. - Choose the brand's address. Either reserve its hosted address (
<brand>.<your domain>, see Brand hostnames), which is also its knowledge base's address, or give it a receiving subdomain of your own, such ashelp.example.com. Use a subdomain that does not already receive company mail. - Add the domain to Resend and publish the DNS records Bouée then shows (DKIM and SPF for sending, MX
for receiving). A Cloudflare connection can create them for you if
CLOUDFLARE_OAUTH_*is configured. The sending domain also needs a DMARC policy before the owner's code can be sent. - Connect incoming email. This registers a Resend webhook for
APP_URL/api/inbound/<workspace>, which Resend must reach over https. - Forward an existing support mailbox to the receiving address if you keep one, and run the forwarding test from the same page.
Staff manage the connection and the sign-in sender later on Instance settings (/instance/settings),
and each brand's addresses under its settings.
