A switch may make sense if Zoho's free plan's one-domain, five-user cap or its lack of IMAP, POP, and Active Sync is a problem. Paid plans start at $1/user/mo billed annually, and Mail Lite has no monthly option. Most alternatives here are email clients rather than custom-domain hosts, so weigh whether you want a new hosting service or a different way to manage existing accounts. Platform support, offline access, unified inboxes, scheduling, calendars, and account limits can help narrow the choice.
