Test mode

Send to these addresses to test your integration. Nothing reaches a real inbox, nothing counts toward your daily limit, and you don’t need a verified domain.

Address	Result
[email protected]	sent, then delivered
[email protected]	sent, then bounced
[email protected]	sent, then complained

Use any address at test.vaartix.com as the sender:

{
  "from": "Acme <[email protected]>",
  "to": "[email protected]",
  "subject": "Testing bounces",
  "text": "Hello"
}

Rules

• Sending from test.vaartix.com only works when every recipient is a test address. Otherwise the request fails with 400 invalid_from_address.
• You can mix test and real recipients when sending from your own verified domain. The test addresses are simulated and the real ones are sent normally.
• Simulated events carry "test": true in their data.
• Simulated bounces and complaints do not add the test addresses to your suppression list.
