Resend (email)
2 min
Send emails from your project: sign-up confirmations, receipts, notifications. Resend's free plan includes 100 emails a day.
Connect
- Create a free account at resend.com. No credit card needed.
- Copy your API key. It is shown after sign-up, or create one in API Keys. It starts with re_.
- Ask the Agent for an email feature, or open Connections → Resend, and paste the key.
Send to your users: verify a domain
Until you verify a domain, emails are sent from [email protected] and only reach your own email address (the one on your Resend account). That is enough for testing.
To email your users:
- Add and verify your domain at resend.com/domains.
- Open the Resend connection and click Re-check.
- In the connection's secrets, change RESEND_FROM_EMAIL to an address on your domain, like [email protected].
Good to know
- If the connection says the key works but no domain is verified, emails still only reach you. Verify a domain as above.
- Usage and limits are managed in your Resend account.
