# Send One-to-One Email
> Send personal, individual emails that appear to come directly from team members
## How Send One-to-One Email Works
Send personal, individual emails that appear to come directly from team members. These emails are optimized for personal communication and typically see higher engagement rates than marketing emails.
One-to-one emails do not respect user marketing email opt-out settings. They should be used sparingly and only when necessary.
## Configuration
The ID of the user who will receive the email.
The ID of the team member the email will appear to come from.
The HTML content of the email. Supports rich formatting and dynamic variables.
Additional CC recipients for team notifications and compliance.
Additional BCC recipients for blind copy notifications.
Whether to stop the workflow if the email fails to send. Set to `true` to halt on failure, `false` to continue.
The status of the email send operation: `success`, `failure`, or `skipped`.
The ID of the user that the email was sent to.
The ID of the email that was sent (available on success).
The options used when creating the email (available on success).
The response from the email creation service (available on success).
The code indicating why the email send operation failed or was skipped: `resend_error`, `duplicate_email`, or `user_marketing_email_opt_out`.
The message of the error that occurred (available on failure).
The ID of the sender configuration used for the email.
