How to get IMAP messages( init) to the (Get transaction) without Queue. Or is queue better?

Hello, I have to get IMAP messages …List… from Init to Get transaction.
I have to filter them with keywords (csv lists) invoices/reminders/others.

Is it better to read or filter the keywords in the Init? before the transaction?
Or only get IMAP and save attachments in the init?

And the most important question: What is the most interesting/efficient way to add/get transaction items?
With Orchestrator Queue or without Queue?
