The setup
Founder Rosa fans studio@ out to four designers. Each owns their projects and replies from their own address.
How the mail flows
- A client sends revision notes with annotated screens Monday.
- All four designers hold the identical notes within minutes.
- The owning designer turns v3 around Tuesday instead of Thursday.
- studio@ keeps the brief history that settles scope debates.
Why Sinka fits here
- Briefs stop queuing behind the founder's inbox.
- Annotated files arrive byte-identical to whoever opens them.
- Contract designers get copies per project, revoked at delivery.
Watch out for
- Version discipline is yours: confirm v-numbers back to the client or designers polish the wrong file.
- Keep invoices on a separate address so creative threads stay clean.
