How server-side deployment works

Three steps from sign-up to live signatures across your entire team.

1

Authenticate

Sign in as admin. We use OAuth 2.0 with least-privilege scopes.

2

Map your team

Match departments and groups to signature templates. Auto-applies to new hires.

3

Deploy

Signatures go live across all mailboxes — usually within 10 minutes.
