Chat opens by itself in a moment. A person is on the other end at any hour, for hosting, domains, billing or anything that has stopped working.
Chat is fastest for a quick question. Anything with detail, screenshots or an account change is better as a ticket.
Tracked against your account, so it does not get lost and anyone on the team can pick it up. Best for billing and anything needing detail.
contact@skycorehost.com — fine for anything that is not urgent, and it reaches the same people.
Sales and billing take calls during business hours. Outside them, chat or a ticket will be quicker.
