The purpose of this seventh permanent email is to discuss Sub-addressing with you, introduce you the concept if you've never heard about it, and how timeNough will use it fully in its first versions, in its MVP and here.
'timeNough' is an enterprise software product hidden behind an organization's local and internal email account. CoreNough LLC, that does not exist in the real world, is the target company here, and firstname.lastname@example.org the email address where the product lives.
With many different names (such as address tagging, plus-addressing, plus-forwarding, address extension, "subaddressing" without the dash or even sub-aliasing), Sub-addressing is a native feature offered by email clients (such as Gmail, Outlook, Yahoo, etc...) that allows you to use multiple aliases for one real email address, such as email@example.com, and publicly disclose these aliases so you can be reached through it. It is not widely known or used, but it can be very helpful in some situations, like if you want to directly place an email into a specific folder when received, without any rules or specific e-mailbox configuration. The alias becomes the rule itself where +something designs an internal mailbox folder called something".
