Despite the wide range of special characters which are technically valid, organisations, mail services, mail servers and mail clients in practice often do not accept all of them. For example, Windows Live Hotmail only allows creation of email addresses using alphanumerics, dot (.), underscore (_) and hyphen (-).[11] Common advice is to avoid using some special characters to avoid the risk of rejected emails.[12]
Providers often bill for dedicated servers on a fixed monthly price to include specific software packages. Over the years, software vendors realized the significant market opportunity to bundle their software with dedicated servers. They have since started introducing pricing models that allow dedicated hosting providers the ability to purchase and resell software based on reduced monthly fees.
Email isn't going away any time soon. Despite a rise in adoption of collaboration-based communication platforms such as Microsoft Teams or Slack, 86 percent of professionals prefer to use email for business purposes. How companies host, store, and distribute their email—that's the area that has undergone a massive transformation. Businesses are veering away from costly onsite email servers running products such as Microsoft Small Business Server and looking instead to the cloud with hosted email solutions. Businesses of all sizes have realized the wisdom of going with a scalable and secure hosted Software-as-a-Service (SaaS) solution with guaranteed uptime that breaks down pricing into flexible, per-user charges.
Earlier forms of email addresses on other networks than the Internet included other notations, such as that required by X.400, and the UUCP bang path notation, in which the address was given in the form of a sequence of computers through which the message should be relayed. This was widely used for several years, but was superseded by the Internet standards promulgated by the Internet Engineering Task Force (IETF).
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.

Line speed, billed on the 95th percentile, refers to the speed in which data flows from the server or device, measured every 5 minutes for the month, and dropping the top 5% of measurements that are highest, and basing the usage for the month on the next-highest measurement. This is similar to a median measurement, which can be thought of as a 50th percentile measurement (with 50% of measurements above, and 50% of measurements below), whereas this sets the cutoff at 95th percentile, with 5% of measurements above the value, and 95% of measurements below the value. This is also known as Burstable billing. Line speed is measured in bits per second (or kilobits per second, megabits per second or gigabits per second).
Running in-house email servers does provide more control and wider customization as well as tracking and compliance for small to midsize businesses (SMB). But they require specialized on-site IT staff as well as the need to manually manage and support both hardware and software. A third-party hosted email service matches many of the advantages of in-house email without the expensive initial investment. The ability to manage the number of users, access the latest security protocols, and enjoy ease of connectivity and deployment of hosted solutions makes it a viable and competitive option.
