Before you share the address

Pause at the point where a hobby account is linked to a professional profile through a reused email. Ask whether the relationship is temporary, whether recovery matters and what would happen if the address became public.

The checklist

  • Separate contact routes
  • Vary repeated identifiers
  • Review profile visibility
  • Protect every recovery path

Write down the purpose beside the credential. A label is small operational memory: it prevents a random-looking address becoming another mystery.

After the first message arrives

Confirm that the route works, that replies behave as expected and that important mail is not being forwarded somewhere unsafe. If the relationship grows, extend the lifetime before it becomes urgent.

Review without over-managing

Give distinct identities independent contact and recovery routes. Review on change—not every day. Writing style, usernames, devices and photos may still reveal connections.

Give the next relationship its own route.
