Free tier

Turns a shared support@ address into an assignable queue for up to three people.
Incoming mail to a shared address becomes a ticket with an owner, a status and a thread, so two people stop replying to the same customer and nothing sits unanswered for a week. The free plan is a real permanent tier rather than a trial: three agents, email ticketing, a knowledge base and basic reports. It is the cheapest honest way off a shared mailbox password.
Questions
A genuinely usable free tier with paid plans for volume or team features. Free caps you at three agents and email only — no SLAs, no automation rules, no live chat or telephony.
Yes. Zoho Desk sends your input to its own servers to process it. That is fine for public material; for anything containing personal data, use one of the on-device tools instead.
