# Email With Resend In DialNexa

> Configure email with Resend in DialNexa using API key, from email, to email, subject, text body, workflow Application nodes, and delivery review.

Email with Resend in DialNexa lets workflows send emails from a connected Resend account. Use it when a call outcome needs written confirmation, a support summary, a lead follow-up, or an internal review notice.

<Note>
  Email actions are wonderfully quiet. That is why success and failure paths matter.
