To setup your own business/family, the process is:
Enter the business or family name you want, and the password you want for the "masteruser" account, and then follow the wizard steps to complete the signup
NOTE: BE SURE TO CAREFULLY READ BOTH THE TERMS OF SERVICE AND THE BULK EMAIL SENDING DOCUMENTS there, which are accessible through the links you will see right at the box you will check to agree to them. To maintain consistent email delivery for all our users, we will lock any accounts that violate our TOS or Bulk Email guidelines.
While you're creating your Business/Family package, you'll be asked to add any existing domains you have, or you can also purchase new domains if you want them.
Note that if you have an existing domain you want to use with us, you'll need to change the DNS for the domain to point to us so that email starts coming to our servers. Please see our domain management help pages for information on how to do this, and what you need to change.
Once your Business/Family package is created, you'll be in the "masteruser" account. This account is not designed for everyday use, it's a "bootstrap" account that allows you to create your real user accounts.
Write down the details of the masteruser account, including your full account name and the password, and store them somewhere safe. In general usage, you will never use or need that account, but if you accidentally forget your password one day, or manage to remove administrator rights from yourself, you can always get back in with the masteruser account
After you've created your business/family container, you'll want to setup an account for yourself, and mark that account as an administrator of the business/family.
If you have an existing FastMail individual account, you can import that into the business/family (see below for import details). If you don't have an existing account, use the "Add / delete / change users" screen to create an account for yourself (see below for account creation details).
Once you have an account for yourself, you can mark it as an administrator of the business/family.
Go to the Manage -> View / manage users screen
Click the "[+]" link in the left column next to your account name
Click the "Give admin rights" link in the menu. This will make You an administrator of the business/family
Now log out of masteruser account and log back in under your own user name. You will now see a "Manage" link in the menu at the top of the page
To change the accounts in a business/family, go to the Manage -> Add / change / delete users screen.
Using the Existing users tab, you can upgrade/downgrade existing accounts, or use the "Delete" column to permanently delete an account.
The New users tab allows you to create new users.
The Build actions tab allows you to download a CSV list of all user accounts, and then you can modify that list in a text editor or a spreadsheet program, and upload the changed list (eg accounts added, service level changed, accounts deleted), and it will interpret the changes as a list of actions to perform.
Once you've made the changes you want, click the "Review and confirm..." button. You'll be taken to a screen where you get an overview of all the actions that will be performed, and how much the entire process will cost (or refund) so you can confirm that's actually what you want before proceeding.
If you have some existing FastMail personal accounts, you can easily import those accounts into a business or family.
Just login to an account that's been marked an administrator of the business/family and go to the Manage -> Import user screen and follow the directions to import the account you want in the business/family.
If your existing account was in a FastMail domain, and you want to move it into one of your own domains, your can do that using the Manage -> Rename user screen after you've done the import.
All money calculations are done on a pro-rata basis, so any remaining subscription is reimbursed, and a new charge is made to bring the account into line with the business/family billing cycle, so no money is lost during the import process.
In some cases, the new cost will be more than the existing subscription, so you'll need to add money to your account to do it. Unfortunately, it can only calculate the amount on an account-by-account basis as you import each account (rather than multiple at once), which can result in a few credit card transactions if you have a number of accounts to import.
If you're ok with that, then just import the accounts one at a time, adding money as needed. If you want to reduce that, you have two options.
You can go to the Manage -> Import User screen and "Calculate" the cost of the import. Repeat this for all the accounts you want to import. Add up the figures it gives for each one, then add that money to your account pool in one go so you can do the imports one after another
When you signup the family/business, you can create "spare" accounts. Create enough spares for the users you want to import, and you'll be charged just one amount for the business/family account & spares. Then when you import the users, it will automatically use your spare accounts. Any pro-rata subscription refund from the old account will be credited to the business/family, which can be used for the next renewal
