Right now, if you want your emails to stay out of the spam folder and have good deliverability, you have to set a 'dedicated header' for the sending domain, which locks the account into sending from a single email address (for all workflows, reminders, conversations, etc.) per domain.

If you want to be able to send from multiple email addresses under the same domain (e.g. mikaela@mail.example.com, nikki@mail.example.com, reminders@mail.example.com, etc.), you have to remove the dedicated header settings. But doing this has a huge impact on email deliverability and heaps more emails start landing in spam because of DMARC issues.

It would be awesome if you could allow users to register and use multiple email addresses per domain, and then the system gives each proper DMARC authentication and whatever else is required (kind of like having multiple 'dedicated headers' per domain).

Most other email platforms already support this. If this change is made, it would make a huge difference for deliverability when wanting to use different email addresses depending on the workflow or audience.
