Zoho Workplace’s Free plan includes webmail-based email and single domain hosting for up to five users. While the plan includes 5GB of storage, free email addresses, and attachments up to 25MB, it doesn’t include the advanced email functionality found with Zoho’s paid plans such as internet message access protocol (IMAP) and post office protocol (POP) support, or integration with other tools like Zoho’s in-house document writer, chat, and video conferencing.
The practice of using a simple memorable abstraction of a host's numerical address on a computer network dates back to the ARPANET era, before the advent of today's commercial Internet. In the early network, each computer on the network retrieved the hosts file (host.txt) from a computer at SRI (now SRI International), which mapped computer hostnames to numerical addresses. The rapid growth of the network made it impossible to maintain a centrally organized hostname registry and in 1983 the Domain Name System was introduced on the ARPANET and published by the Internet Engineering Task Force as RFC 882 and RFC 883.
One of the most important compatibility factors to consider with email is the mobility question. How often do your employees need to access email via mobile devices? That's an important issue because most email hosting providers deliver some kind of web client usable as a default inbox. Almost all of these can be accessed via a mobile device, so if your employees don't need to access their emails on the road that much, then such mediocre clients are probably fine.
