I usually "recycle" email addreses to avoid license payments. For example:
normalemail@test.com and the recycled one would be, normalemail+alt@test.com
Gmail allow that, and it eases some automatic activities.
Anyways, when I am trying to share a sheet in smartsheets, the system does not allow to do that, and alerts that the email address is not valid.
Is there a way to escalate that to smartsheets support?
