Send a courteous acknowledgment when a support ticket has no matching approved answer and leave it open for an Agent.
Post the next shift's chat list of tickets awaiting a personal reply.
Customers get a receipt after hours, and your next support shift sees which tickets still need a personal reply in team chat.
Send approved answers to matching tickets and acknowledge the rest.
Your customers hear back by email on familiar questions, while tickets needing a personal answer stay open for your support team.
