Send mail notifications in queue

[Aku-benj]

Question

Hey,
Could mail notifications be sent asynchronously in the queue or else instead of in the main thread of the current action ?

Additional context

I am using an SMTP server to send my notifications and today my SMTP logins attempts were failing.
Because of that, on each submission's actions (creation/approbation), the 8 notifications (one for each reviewer) were failing causing timeouts.
I temporarly disabled the notifications and each actions were now instant.

Versions :
Craft CMS | PRO | 4.14.15
Workflow | 2.0.15

Good idea, using the queue should be an option for performance. I'll look into it.
