Book calls for local clients:outbound with Clay and Esy

The outbound system we run for local service businesses: Clay finds and checks them, Esy writes, waits for your sign-off and sends. What it booked, and how to sell it to your clients.

A sample issue. The campaign, its numbers and the prices are examples from Esy’s sample data, and Esy doesn’t connect to Clay yet.

Most agencies get their clients from referrals. It works until it doesn’t, and when referrals slow down, so does the agency.

This week is the outbound system we run to find local service businesses that need to show up in AI search, and to book calls with them. You can rebuild it for your agency this week, then sell it to your clients as a retainer.

One rule before the steps: AI does the research and the first draft. A person signs off every first email. That’s what keeps it from reading like spam, and it’s the answer when a client asks “is this AI?”

How the system works

  1. 1

    Write the rules You

    Who fits, in plain lines you can prove wrong: roofing contractors in four Texas metros, 25+ reviews rated 4.2 or better, a site with two or fewer service pages, no franchises. Esy keeps each version of the rules, so you can see which one won clients.

    Rules v3, from 3 won and 5 lost
  2. 2

    Build the list Clay

    A Google Maps search by category and city fills a Clay table. Filter columns apply your rules, and anything that fails says why.

    412of 1,240fit the rules. 301 had no website: a different offer.
  3. 3

    Find a reason to write now Clay

    Clay’s research agent reads each site and the latest reviews: a storm in their area last week, a service they offer with no page, a review asking for something they don’t list.

  4. 4

    Find who decides, and check the address Clay

    A waterfall of email finders, cheapest first, stops at the first hit. A verification check runs after it, and catch-all domains are held instead of guessed.

    Send it to Esy Clay → Esy

    Each approved row goes to os.esy.com’s Outreach, into “To reach”. Every field keeps where it came from and what it cost.

  6. 6

    Write, sign off, send Esy

    Scout writes the first two lines from those facts only, and notes the source of each. You sign off every first email. Esy sends from warmed mailboxes, in their morning, a few dozen a day.

    84of 120emailed so far. The rest wait for a mailbox slot.
  7. 7

    Replies and calls Esy

    Replies are sorted into interested, not now and out of office, and the sequence stops for anyone who writes back. A yes books on your calendar and lands in your CRM with the thread.

How Clay plugs into Esy

A column at the end of your Clay table sends each approved row to Outreach in os.esy.com. It arrives in “To reach” with its sources.

Esy to Clay
When you approve one business by hand in Esy, Esy asks your Clay table to enrich it and fills in the answer when it comes back.
Costs
The Clay credits each row used land on the campaign’s spend, beside address checks, drafting and mailboxes, under one budget cap.

This connection is hypothetical: Esy doesn’t talk to Clay yet. Today you’d export a CSV from Clay and import it. The screen is a mock with sample rows.

What it cost us

Clay data$38.40
Address checks$1.90
Scout’s drafting$0.62
Mailboxes, share of the month$12.00
Total$52.92
Per reply$4.81
Per client$52.92

The biggest drop wasn’t the email. It was the list: 301 roofers had no website at all. They need a site before they need AI search, so they’re a different offer, and a different campaign.

For your clients

Booked calls for local service businesses

  • The rules, written with the client and kept as versions
  • One campaign a month: the list, the research, the emails
  • Every first email signed off by your team
  • A weekly report: found, emailed, replied, booked
Setup$1,500 once
Monthly$1,000
Or per booked call$150

Example prices, for a shape to start from.

  • Data and sending for one campaign: about $52.92 (our numbers above).
  • Your team’s time: about 20 minutes a day of sign-off and replies.
  • Price it on calls booked, not hours. The hours keep shrinking; the calls are what the client values.
“Is this AI?” AI does the research and the first draft. A person on your team reads and signs off every first email before it goes. That’s also why it doesn’t read like spam.

The weekly skill

First lines from facts

Give it the facts Clay found: their reviews, the gap on their site, the reason to write now. It writes two opening lines that use only those facts, cites each one, and flags any line it can’t source.

Worth your time

  • Clay: The tool this issue builds on.
  • Outreach in Esy: Where the sign-off queue, the pipeline and the costs live.
