Mailbox provides aliases for free, meaning emails of both myname@domain.com and theirname@domain.com will come to a single account.
You would need to buy another account in order to keep both of them separate.

Thanks for the clarification.
So thinking outside the box would either of these work.
A) Point my domain to Anonaddy instead of mailbox.
Then I link the aliases to different recipients. So myname@custom to go to my fastmail and theirname@custom to go to their gmail.
B) Leave myname@custom pointing to mailbox. Then setup a subdomain and point that to anonaddy, and use their gmail as a recipient. They'd end up with theirname@mail.custom.
I'd think A would work (pointing your custom domain to Anonaddy and linking the specific alias to their gmail as the recipient for that alias). This can be done w/ Anonaddy's Lite Plan, which is $1/month and allows up to 5 recipients.
Yep. Went with A and initial tests work.
The only thing is being somewhat limited to incoming mail per month. I'll just monitor it.
Plan B I thought should technically work too but hard to organise.
And it looks like mxroute, puremail, and migadu (spelling?) offer multiple accounts and mailboxes. But they arnt so privacy focused.
I don’t know about mailbox.org, but with Fastmail I use a combination of explicit aliases and a catchall alias. The catchall and some individuals direct to me, but other individuals go to me and my spouse@gmail, while others go only to spouse@gmail. The per-user fee is about how many distinct mailboxes with different passwords exist in the service, so I’m only paying for one for me, and the aliases are configurable to resend incoming mail externally.
Is this via a rule, as in the email hits the inbox then gets sent on.
Or is it a setting when you configure the alias.
Where the email goes to fastmail then gets sent onto gmail, are you limited to replying from the gmail?
Each alias has a configured delivery destination. Aliases that only point externally never reach the main account inbox.
You are limited to replying from the gmail unless you jump through more advanced hoops. Those include telling gmail in its settings that it can “Send mail as” something else, and also giving gmail authorization to send mail for your domain by adding them into your SPF and DKIM records. Those are more complicated than I want to describe here, and it will be complicated to merge both mailbox.org and gmail into them, so if you don’t already know about them, let’s just say yes, you can only reply as the gmail user.
I'd be doing everything you can to move any and all emails out of outlook.
That's the plan.
But anonaddy vs catchall/alias on own domain ?
I use someone else's domain for privacy reasons. Any email with your personal domain in it can be traced back to you.
