How to set up a shared inbox that never drops a lead for plumbing companies

Short answerDo not share the password. Add people as delegates instead: Settings, Accounts and Import, Grant access to your account, Add another account. A delegate can read, send and delete mail in that account without your password. Then build three Gmail filters that label incoming mail by urgency so the emergency call is not sitting under a supply house newsletter. The one thing to know up front: when a delegate sends a message, their own email address appears on it.

How to do it

1

Pick one address and stop using personal inboxes for leads

Every web form, every listing, every truck wrap goes to one address. Not the owner's personal mail. The moment leads arrive in two places, one of them stops getting checked, and it is always the one with the $8,000 repipe in it.

2

Add your dispatcher as a delegate, not a password holder

In Gmail settings, open Accounts and Import, find Grant access to your account, and click Add another account. Enter their address and send the invitation. They accept and the inbox shows up in their own Gmail. Nobody types a shared password into anything, and you remove access by deleting one line when somebody leaves.

3

Know what a delegate cannot do before you promise it

Delegates can read, send and delete mail. They cannot chat, cannot change your password, and cannot reach Google Account settings, Drive attachments, Photos, Tasks, client-side encryption, Gemini, Meet, Smart Compose or spelling checks in that account. For a dispatcher answering plumbing leads, read, send and delete is the whole job. For anything else, check the list first.

4

Build the emergency filter first

Click Show search options in the search box, put your emergency words in the has-the-words field, then click Create filter and apply a label. For plumbing that list is short and specific: burst, flooding, no water, sewage, backup, gas smell, water heater leaking. Add star as well so it is impossible to miss on a phone screen.

5

Add a quote-request filter and a noise filter

Second filter labels anything from your web form address as Quote. Third filter takes the suppliers, newsletters and software receipts and archives them with a label so they skip the inbox entirely. Never use delete as a filter action on anything that touches customers. Archive is reversible, delete is a lead you will never know you lost.

6

Use a label as your answered flag

Make one label called Answered and one called Needs Quote. The rule is simple and has to be said out loud: if you reply, you label it. Gmail has no built-in assignment, so the label is your assignment system, and two people replying to the same homeowner is how a shared inbox loses trust in week one.

7

Run the backlog by hand, once

Filters that forward only affect new messages, and label filters you create apply going forward unless you tell Gmail to apply them to matching conversations. Set aside 20 minutes and clear what is already in there. Do it once and the system is clean from that point on.

8

Route what has to leave Gmail with a Paths step

If a labeled lead needs to land in your field service software or a text to the on-call tech, that is a Zapier job, not a Gmail job. One Paths step with an emergency branch and a standard branch covers it, and you can add a fallback branch so an unmatched lead still pings a human instead of vanishing.

Common questions

Do I have to give out the password?

No, and you should not. Delegation gives someone read, send and delete access to the inbox without the password, and delegates cannot change it either. Removing a person is one click in Accounts and Import instead of a password reset that locks out everybody else.

Does this need Google Workspace, or does a regular Gmail work?

Both work. Delegation exists on personal gmail.com accounts with a cap of 10 delegates. A work or school account raises that to 1,000. If you are running a business on a gmail.com address, delegation is still a real improvement over a shared password today.

What should the emergency filter actually match on?

Words a panicked homeowner types, not words you would use. Burst, flooding, leaking everywhere, no hot water, sewage, backed up, gas smell, cannot shut off. Review the list every few months against what actually came in. The words your customers use are better than the words in any template.

Can I mark leads as handled so nobody doubles up?

Only with a label you enforce yourself. Create an Answered label, apply it the moment you reply, and make the shared rule that unlabeled equals unhandled. It is low tech and it works, as long as everyone does it every time.

Sources

  1. Add another person to manage your Gmail — Google Gmail HelpDelegation is set in Settings, Accounts and Import, under Grant access to your account with Add another account; delegates can read, send and delete mail but cannot chat, change the password, or reach Google Account settings, Drive attachments, Photos, Tasks, client-side encryption, Gemini, Meet, Smart Compose or spelling; personal accounts allow up to 10 delegates and work or school accounts up to 1,000 with about 40 simultaneous; the delegate's email address appears when they send.
  2. Create rules to filter your emails — Google Gmail HelpFilters are created from Show search options in the search box then Create filter, or from a message via More and Filter messages like these; available actions include label, archive, delete, star and forward; a forwarding filter affects only new messages.
  3. Add branching logic to Zaps with paths — Zapier HelpPaths route a record into different action sequences with custom rules, an always-run option and one fallback branch per group that runs when nothing else matches.
