Mailboxes vs Domain Aliases
Mailboxes
An email mailbox is some disk space on a mail server where email is stored. At SWCP each account has mailbox storage allocated and the email address for that account is account@swcp.com. We refer to this as your SWCP email address.
Domain Aliases
You may have a domain name that you've registered for your business with the intention of having a website and you'd probably like to use it for email as well. The way this works is we set up an alias using your domain to be directed to an email mailbox. This alias doesn't have any physical storage space. It just acts as a redirection.
Think of it like this: if you're an author and you have a pseudonym your fans may write to you using your pseudonym. You publishing company we forward that mail to your actual address without the fans having to know where you live. A domain alias is like that. And it can be redirected to several different email mailboxes.
Managing your domain aliases
If your domain is registered with SWCP you can set up unlimited email aliases from the members dashboard [mp.swcp.com]. Login and go to "Mail Tools" then "Domain Email Aliases". From there you can select the domain you want to work on and set up your aliases. They can be sent to your SWCP email addresses or to offsite email addresses like Gmail.
