Set a custom "To" header

Estimated time to read: 1 minute

Add this to the content.headers to override the To header. Use this in test mode to display the original recipient address but deliver emails to your own mailbox.

Example (API):

{
  "to": "customer@example.com",
  "subject": "Test Bounce Scenario",
  "text": "This is a message.",
  "headers": {
    "seseu-to": "dev@agency.com"
  }
}
