1. Open Google Contacts using the intended business account.
2. Search for the people already present before creating new records.
3. Select the contacts and apply an existing label or create a clearly named one.
4. Open the label and review its membership and each person's intended email address.
5. Correct duplicates or outdated details carefully, preserving information you still need.
6. Test recipient selection in Gmail without immediately sending to the entire list.

A contact can have several email addresses, and a saved list can become stale. Inspect the actual expanded recipients before sending. Use Bcc when recipients should not see each other's addresses and your business process permits the message.

If several staff members need a centrally managed address and membership, create an authorised Google Group. A personal label can depend on one person's account and does not provide the same ownership, posting or moderation controls.

Review suggested merges before accepting them. Two people with the same name are not necessarily duplicates, and separate business and personal records can be intentional. Keep an export before a large cleanup where the consequences would be difficult to reverse.

For staff handovers, document which lists are personal convenience and which are business-owned communication channels. Do not rely on an employee's private contact labels as the only record of customers or suppliers the organisation needs to reach.
