It is also necessary to study email alternatives as part of your email service setup plan. Email is the standard way to communicate and it is familiar to most users, but it isn't always the most effective or expedient method. Email can be slow, result in delayed responses, and messages are rarely read to completion. Because of this, many businesses require additional "collaboration" tools, that various email services also include, in order to fill the communication gap more effectively.
A domain name consists of one or more labels, each of which is formed from the set of ASCII letters, digits, and hyphens (a-z, A-Z, 0-9, -), but not starting or ending with a hyphen. The labels are case-insensitive; for example, 'label' is equivalent to 'Label' or 'LABEL'. In the textual representation of a domain name, the labels are separated by a full stop (period).
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.
