Restrictions on the Service to prevent spam

In order to prevent spam, there is a mechanism that limits the number of messages you can send. You will see a warning in your personal account. If you do not agree with this solution, please contact technical support.

If this situation occurs, you may see the following errors when sending:

{
  "errors": [
    {
      "code": 429,
      "detail": "Too many messages. Try again in 92 seconds."
    }
  ]
}
