Resend

Resend lets you send emails from your own domain with a simple API. ClientHunter can use Resend to send cold emails and, optionally, Resend templates. Reply detection for two-stage flows uses Resend Receiving and a webhook.

What you need

  • A Resend account (resend.com).
  • A Resend API key (starts with re_).
  • A verified domain and a from address in Resend (e.g. noreply@yourdomain.com).

Step 1: Get your API key

  • Sign in at resend.com.
  • Go to API Keys and create a new key.
  • Copy the key (it starts with re_). Keep it secret.

Step 2: Verify your domain and from address

In Resend, add and verify your sending domain. Then ensure the "from" email address you plan to use (e.g. noreply@yourdomain.com) is allowed for sending. ClientHunter will use this address when you connect.

Step 3: Connect in ClientHunter

  • Go to Accounts in the dashboard.
  • Click Add Account.
  • Click Connect Resend.
  • Enter your Resend API key.
  • Enter the from email (must be verified in Resend).
  • Optionally enter a from name (e.g. Your Company).
  • Click Connect.

Using Resend templates

If you use the "Resend template" mode in a project, select your Resend account and enter the Resend template ID. Emails will be sent using that template; variables are replaced when sending.

Reply detection (two-stage campaigns)

For two-stage flows (question first, follow-up after reply), Resend does not use the same thread as Gmail or AgentMail. You need to set up Resend Receiving and point the "email.received" webhook to your ClientHunter receiving endpoint. When a reply is received at a Resend receiving address, ClientHunter matches it to the campaign and can send the follow-up.
Configure Resend Receiving in the Resend dashboard and add a webhook for the email.received event to the URL provided in your ClientHunter account or docs.

Next steps

After connecting, create or edit a project and select your Resend account. Choose custom template (subject/body) or Resend template (template ID) and run your campaign.
