Workspace secondary domain, send receive emails free?

[jeduke02]

My workspace is set up as

DOMAIN1 - Primary Domain

DOMAIN2 - Secondary Domain (and the one I registered with workspace, Business Standard)

DOMAIN3 - Not yet purchased, but I will and I want to add this one.

How should I add DOMAIN3 so that I can send and receive email for it?  I don't need storage space associated with it since I already have workspace business standard with DOMAIN2.  Can I just add it as a secondary domain and then activate gmail and use any email log in I want to send and receive?

Should I make it it's own user and pay for another account?  

How much gmail storage do I get if I utilize either option?

I watched that a few times.  

If I do Option 1 - Alias Domains, then the storage space used is what?  How much space does that get?  Does it get dumped into whatever the main domain space is?  Is this correct?

If I do Option 2 - Then that's just another business standard account and that's whatever it costs and I get 2 TB for that user.

The amount of space you have/amount of space you use/number of accounts you pay for is not linked to whether you have secondary or alias domains.

The real difference is whether you want *all* of your accounts to be reachable at both domains (both example1.com and example2.com), which is called an alias domain; or if you want the option to use the two independently (some accounts are reachable at example1.com, some at example2.com, some at both), which is called a secondary domain. 

Hope that helps,
