A practical checklist for email aliases

Before you share the address

Pause at the point where a new service asks for an email before explaining how it will use it. Ask whether the relationship is temporary, whether recovery matters and what would happen if the address became public.

The checklist

• Name the relationship
• Choose a suitable lifetime
• Store it with the account
• Review it when the relationship changes

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 each important relationship a labelled, controllable address. Review on change—not every day. An alias separates the address, not every other identifier a service collects.
