The IETF's EAI Working group published RFC 6530 "Overview and Framework for Internationalized Email", which enabled non-ASCII characters to be used in both the local-parts and domain of an email address. RFC 6530 provides for email based on the UTF-8 encoding, which permits the full repertoire of Unicode. RFC 6531 provides a mechanism for SMTP servers to negotiate transmission of the SMTPUTF8 content.
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. 

One great way to protect data is by using email encryption. This feature can do wonders for protecting your organization's privacy and that of your employees, but it demands some investigation when you're selecting your provider. Is it built-in or do you require a third-party tool? Does it use common standards that the recipient can process? What about Secure Sockets Layer (SSL) certificates? Are they included or do they need to be purchased separately? The best-in-class tools will not only make encryption easy for anybody to configure and use, buy they'll also make it easy for you to understand pre-purchase.
While most businesses will have such suites in place, it often falls to the email service to provide an additional layer of anti-phishing and anti-malware protection. Our reviews found a surprising variance in this department, however, ranging from very robust to completely non-existent, so be careful. Since it's such a huge liability for business owners, this could be one of the most important factors in terms of background features. At the very least, it's better than filing an insurance claim or outright losing funds due to simple social engineering tactics.
Above all else, we strive to deliver outstanding customer experiences. When you buy a domain name from Namecheap, we guarantee it will be handed over to you with superior standards of service and support. Our primary goal is to build a customer-focused atmosphere filled with the happiest customers in the galaxy. The Namecheap guarantee is our mark of excellence.
Hosted email often comes as part of another service, such as web hosting or Infrastructure-as-a-Service (IaaS). Since that means there will be many extras available with these services, it's inescapable that you'll be paying for those extras in some way. Purchasing them usually means a slight uptick in that per-user price. Many businesses find that, once they're done selecting all of their needed "optional extras," their end price can often reach as high as $10 or more per user. This can start to add up for larger teams. It's somewhat like buying cable service: sometimes you need to pay for the channels you don't want to get the couple of channels that you need. There is also the old adage that "you get what you pay for" when it comes to quality. This is almost always true when considering an email host.
Our aim is to keep our servers clean from malware, phishing, and other malicious activities posing threat to Internet users. It does not mean that we judge before knowing you, but today's reality is that we can not predict intentions of every user who signs up. In order to prevent misuse of our services we had to apply certain limitations to free hosting accounts. In turn our servers are never blacklisted so you can always expect your email message to reach it's recipient, and Internet users to reach your website.
