- We will not respond to services that require interaction (e.g., spam challenge/response).
- Do not expect an instant response. In most cases, a response is sent within one hour, but please allow 12 hours with the rare exception of travel, where responses can be delayed up to a few days. Check the delivery status if more than 24 hours has elapsed, but first check your spam box, this is 99% of the issue.
