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]
No. At GoDaddy, we are upfront about pricing. If we advertise cheap domain registration for C$1.31 or C$13.19 for the first year, then that’s the price you can expect to pay. While many customers choose to purchase additional products to grow their online presence, you are not required to buy other products to complete registration for a cheap domain name. If you are taking advantage of a special domain offer or first-year registration pricing, you will be notified about the limitations of the offer and future pricing changes at the time of purchase.
You can certainly do that, but it’s often a lot of effort. Not sure it it’s worth it. Even when you narrow it down to one contact – it may not be that one contact at all, but something about his or her email provider, the path to that email provider or something else. It’s difficult (and inadvisable) to point fingers. On the other hand, it’s fairly common when signing up for mailing lists, or leaving comments on web sites that require an email address to use a specific email address to see if THEY end up spamming you. People use Ask Leo! – specific email addresses when leaving comments all the time. (And, no, I don’t spam ’em 🙂 ).
This is how I started doing hosted e-mails, but I recently switched to using Google Apps. If you have a small business (up to 10 users), you can use Google Apps 100% free. Gmail handles the mail, your e-mail has your domain associated with it, and you can link that e-mail up to other Google features (Google docs, Google voice, add-on apps like a CRM or accounting). Best of all, I can sync it all effortlessly with my android phone, so now all of my e-mails still come to my phone… but they’re sorted neatly by account.
Your next major concern will be compatibility. It's not a shock that most businesses run on Microsoft Windows and use some form of Microsoft Office. Being able to use common third-party clients such as Microsoft Outlook can often be a concern, and even today, compatibility with Microsoft Outlook isn't necessarily guaranteed. This is especially true when sending and receiving meeting invites. It only takes one garbled meeting invite to realize how frustrating this can be in the real world. Even if using Microsoft Outlook isn't a concern, portability is. If the service is entirely web-based, then is there a means for me to take my email offline and send email when I connect?

The cloud certainly makes delivering email to your users easier but, for the vast majority of organizations, there's still going to be some setup required beyond simply activating the service. At a minimum, a domain must be purchased and configured to point to the new email host. The service provider can make this process very simple or they can make quite hard; this is something you should watch for in the provider's customer support forums as well as in our reviews. In most cases, there is a validation phase that will require some technical familiarity, though a few providers go so far as to walk even neophyte users through it step by step. Other solid services bolster excellent support with tutorial articles and videos that also walk you through the process. The worst will leave you to figure it out on your own.
In practice, the form validation of some web sites may reject special characters such as "+" in an email address – treating them, incorrectly, as invalid characters. This can lead to an incorrect user receiving an e-mail if the "+" is silently stripped by a website without any warning or error messages. For example, an email intended for the user-entered email address [email protected] could be incorrectly sent to [email protected] In other cases a poor user experience can occur if some parts of a site, such as a user registration page, allow the "+" character whilst other parts, such as a page for unsubscribing from a site's mailing list, do not. 

Interpretation of the local part of an email address is dependent on the conventions and policies implemented in the mail server. For example, case sensitivity may distinguish mailboxes differing only in capitalization of characters of the local-part, although this is not very common.[13] Apart from work, school, or organization addresses, gmail ignores all dots in the local-part for the purposes of determining account identity.[14] This prevents the creation of user accounts your.user.name or yourusername when the account your.username already exists.
