Import the staff list, send everyone their link, and stop being the person who edits HTML every time someone gets promoted.
CSV in, everyone created, each with their own durable link. No seat provisioning, no invitations to accept.
One click sends every person their personal page with step-by-step install instructions for their mail client.
The dashboard shows who has copied theirs and who has never opened the link, so you chase two people rather than forty.
