Plumber database with emails: what each record holds and how to use it

By 67Leads Team · Published 12 Nov 2026 · Updated 12 Nov 2026 (US Central) · 6 min read

A plumber database is a searchable set of plumbers with a phone, a website, an owner name where the company's site gives one and an email checked against the mail server. As of 13 Nov 2026, the 67Leads warehouse holds 16,378 sellable plumbers with a phone. 92 of them have an email, 40 of those emails were confirmed by the mail server, and 1,369 name an owner on their own site.

Shortcut: the plumber lead list shows counts by state and city, the verified emails and owner emails pages apply the email filters, and the email verifier checks a single address.

What is in the plumbers list

These are the live counts today:

Counts are listings that match today and move as the data refreshes. Not every company has an email, so a list of plumbers with emails is smaller than a list of every plumber we hold. Call the rest.

What the columns are

Each row in the default export holds:

• Company and category. The business name and what its listing says it does.
• Phone and line type. The number, and whether it is a local or a toll-free line.
• Website and domain. The site on the listing, or blank when there is none.
• Email and email status. The address, read from the company's own website, and the result of the check.
• Owner name. Filled only when the company's site names one, with where it came from.
• Address. Street, city, state and postal code.
• Rating and review count. From the public listing.

How the emails are checked

Emails are read from the company's own website. None is guessed from a name pattern. Each one is then checked over SMTP: we ask the company's mail server whether that exact mailbox exists. Nothing is sent.

• Verified. The server said the mailbox exists.
• Catch-all (labelled risky). The server accepts every address, so the check cannot tell if this one is real. These are not counted as verified.
• Invalid. The server said the mailbox does not exist.

A check shows the state of a mailbox when it was run. It does not show that a person reads it, and addresses can go stale as people leave and domains lapse. Run the rows you plan to use through the email verifier again before a large send, and drop any hard bounce at once.

Filter the list by state

These are the states with the most sellable plumbers in the warehouse today:

States with 50+ sellable businesses, largest first, live from the 67Leads warehouse.

Work one state or one metro at a time so your message can name a place. The plumber lead list filters by state and city.

Who buys a plumber email list

• Plumbing supply houses and tool brands. They sell to the owner who sets the order.
• Dispatch and invoicing software. Small shops often still use paper and a phone.
• Marketing and answering-service vendors. A missed call is a lost job, so a call-handling offer has a clear fit.

Plumbers take emergency calls at any hour, so an owner may read email in short bursts between jobs. Lead with something that saves a call or wins a job, name the city and offer one clear next step. Winter freezes and the spring rush are busy, so aim for quieter weeks.

Pair the email with a call when the list shows no email. A phone is on every row, and the cold email grader scores a draft before you send it.

Use it legally

Email to a business is covered by CAN-SPAM. The law makes no exception for business-to-business messages, so every commercial email needs:

1. A true sender name and a subject line that matches the message.
2. A clear sign that it is an advertisement.
3. Your valid postal address.
4. A working opt-out that you honor within 10 business days.

Keep a do-not-email list and check each send against it. The FTC's CAN-SPAM guide covers the rules and the CAN-SPAM checker tests a draft. Never send to a hard bounce twice.

Most states license plumbers, and some require the licence number in advertising. Check the state licence before you write about a company, never claim a licence you cannot see, and leave out anything you cannot back up.

Do not text the phone numbers on the list as a first touch. Texting a business needs consent under the Telephone Consumer Protection Act, and a listed number is often the owner's own mobile. This is general information, not legal advice.

What it costs

Search and counts are free, with emails and phones masked. Your first 67 leads export free, and after that credits start at $6.70 per 1,000. Monthly plans are on the pricing page.

How 67Leads fits

67Leads is a search over public business listings and company websites. Companies are graded against the trade, and off-trade rows are never sold. Open the plumber lead list to filter by state, then use the verified emails pages to narrow to rows with an email. The email verifier and the lead list cleaner help before you send.

Questions

How many plumbers are on the list?

As of 13 Nov 2026, 16,378 sellable plumbers with a phone, and 40 of them have an email the mail server confirmed. That counts the listings we hold, graded against the trade, not every plumber in the country.

What does a verified email mean?

The company's mail server was asked whether the exact mailbox exists and said yes. A server that accepts every address is labelled catch-all and is not counted as verified.

Are the emails guessed from names?

No. Each address is read from the company's own website. None is built from a name pattern.

Do plumbing companies have a website?

Many small ones do not, or have a site that no longer loads. The no-website count above is the number of plumbers in the warehouse with none listed.

Can I get the owner's name?

Where the company's own site names an owner we record it. The owner count above shows how many plumbers have one today.

No card. Search is free with contacts masked.
