How big is the marketing agency market?

Marketing agencies are many small firms and a few big ones. The Census Bureau counted 15,512 advertising agency establishments with paid employees in 2023 (NAICS 541810), led by California (about 2,460), New York (1,610), Florida (1,370), Texas (1,260) and Illinois (660). That code is only part of the picture: digital marketing, SEO, PR, media buying and web design shops are often filed under other codes, and thousands of one- and two-person agencies have no payroll at all. On Google Maps they all show up as marketing agencies, internet marketing services or website designers. The founder usually signs off on tools and vendors, and most agencies buy software that helps them deliver more client work with the same headcount.

How many marketing agencies are there in each state?

California, New York and Florida have the most. The Census Bureau counted 15,512 establishments in Advertising agencies (NAICS 541810) across the 50 states and DC in 2023. These are locations with paid employees, so one-person businesses aren't included and the real number of businesses is higher. Use it to size a market before you build the list.

What's in a marketing agency lead list

Every row is one marketing agency business found on Google Maps inside the area you chose, with its email found on its own website and checked against the live mail server. These are the columns that matter most for marketing agencies:

Field	Why it matters for marketing agencies
category / categories	Splits full-service and ad agencies from SEO shops, web designers and PR firms. A white-label SEO vendor and a print broker want very different subsets.
email + grade	Agencies publish hello@, info@ or a founder's name. Verified means the mailbox exists; Accept-all means the domain takes any address, so treat it as a maybe. Agencies tend to run their own mail setups, so expect some of each.
emails (up to 5, with role and source)	Bigger agencies list new business, careers and press addresses. The role and the page it came from help you write to new business or the founder, not the jobs inbox.
website + website_platform	An agency's own site says a lot about its stack. The platform column shows who builds on WordPress, Webflow or a hosted builder, which matters if you sell plugins, hosting or white-label builds.
rating + reviews	Agencies with many client reviews are established and usually hiring. Agencies with almost none are small or new, and often buy lead lists and outsourced fulfilment.
linkedin / instagram / youtube	Agencies market on social. The links show who posts and where, and LinkedIn is where you check the founder and team size before you write.
address + in_area	Many agencies are remote or run from coworking spaces. The area columns keep the list to agencies that list an address or service area in your market.

About 45 columns in all, including up to five emails per business with their role and source, and eight social networks. See a sample export.

Search terms that find every marketing agency

No single keyword finds them all. Businesses file themselves under different Google Maps categories and describe themselves in different words, so a complete list searches every variant across the whole area, then removes duplicates.

Search terms: marketing agency, digital marketing agency, advertising agency, ad agency, seo agency, seo company, local seo services, ppc agency, google ads agency, social media marketing agency, social media agency, content marketing agency, email marketing agency, branding agency, creative agency, web design company, website designer, web development agency, public relations firm, pr agency, media buying agency, video production company, marketing consultant, internet marketing service, influencer marketing agency, lead generation agency.

Google Maps categories: Marketing agency, Advertising agency, Internet marketing service, Website designer, Marketing consultant, Public relations firm, Graphic designer, Video production service.

Leadraft includes these in its Professional & B2B keyword pack (66 terms), and suggests more in your country's vocabulary when you type a trade.

Who sells to marketing agencies, and what works

White-label and fulfilment providers. SEO, PPC, web builds, content and design delivered under the agency's brand. Pitch the founder on margin and turnaround: what the agency charges the client vs what you charge, and how fast you deliver.
Marketing and agency software. Reporting dashboards, client portals, social scheduling, proposal and invoicing tools. Agencies buy tools that save account manager hours. Lead with hours per client per month, not features.
Lead generation and data tools. Agencies need new clients all the time. Show them how to build a prospect list for a niche and city in minutes (see how to get leads for a marketing agency).
Freelancers and contractors. Designers, developers, copywriters and media buyers who want agency overflow work. A short note with two relevant samples and a day rate works better than a full portfolio.
Printers, promotional products and video studios. Agencies resell print, swag and video to their clients. Offer trade pricing, blind shipping and fast proofs.
Agency brokers and acquirers. Buyers looking for agencies to acquire in a metro. Filter to established agencies with strong review counts and reach the founder with a respectful, short note.

How to segment and qualify a marketing agency list

By service

Run separate searches for SEO, PPC, social, web design and PR terms and tag each row by the term and category that found it. A white-label SEO offer goes to SEO and web design shops, not PR firms.

Solo and small vs established

Review count and website depth are good size proxies. Small agencies buy fulfilment and lead lists; larger ones buy software seats and hire freelancers.

Niche agencies

Many agencies serve one vertical: dental marketing, law firm SEO, restaurant social. Their names and sites say so. These are strong leads if your offer fits that vertical, and you can pair them with the matching list, like dentists or law firms.

Web designers

Website designer is its own Google Maps category and often the largest group in a city. Keep it as a separate segment for hosting, plugin and white-label development offers.

Newly opened agencies

New agencies need everything: tools, a site, first clients, a fulfilment partner. A monitor on your area surfaces new listings as they appear on Google Maps.

How to reach marketing agencies

Write to the founder, briefly

In most agencies under 20 people the founder buys. They get a lot of cold email and know the patterns, so skip the flattery, name one specific thing about their agency, and make one clear offer.

Avoid month-end and launch weeks

Agencies are busiest at month-end reporting and around client launches. Mid-month, Tuesday to Thursday, is when founders have time to read.

Show the margin

Agencies think in retainer margin and billable hours. "You bill $1,500 for this, we deliver it for $600 in five days" lands better than a list of features.

CAN-SPAM and TCPA

Commercial email to businesses is covered by CAN-SPAM: honest subject lines, your physical address and an opt-out that you honor. Many listed agency numbers are founders' cell phones, so calls and texts fall under the TCPA: dial by hand and don't send marketing texts without consent. Read our cold email laws guide and get legal advice for your setup.

How to find marketing agency leads: build the list in four steps

Choose the place. A city, county or ZIP code, a radius around an address, or a shape you draw on the map (or a KML file).
Search every variant. Start from the terms above. Leadraft splits large areas into tiles so you get the businesses past Google's first few hundred results, and keeps only the ones inside your area and in the trade.
Preview before you pay. The free preview shows real businesses already found there, with emails masked.
Export or push. Download CSV or XLSX, or send the Verified emails straight to Instantly, Smartlead, lemlist or HubSpot with your suppression list applied. Each business is charged once, ever.

Marketing agencies lead lists: questions

How do I find marketing agency leads?

Pick the city, county or ZIP code you sell into, search the agency terms that match your offer (marketing agency, seo agency, website designer, advertising agency, public relations firm) and let Leadraft collect every matching business on Google Maps inside that area. It then finds up to 5 emails on each agency's own website and checks every mailbox, so you export only Verified and Accept-all emails.

How many marketing agencies are there in the US?

The Census Bureau's County Business Patterns counted 15,512 advertising agency establishments with paid employees in 2023 (NAICS 541810). That undercounts the market you'll see on Google Maps: digital, SEO, PR and web design shops are often filed under other codes, and many agencies are one-person businesses with no payroll.

Can I get a list of only SEO agencies or web designers?

Yes. Search only the terms for that service (seo agency, local seo services, website designer, web design company) and filter by the category column. Leadraft records each business's Google Maps categories, so you can keep a Website designer list separate from Advertising agency rows.

Are the emails verified?

Each email is checked against the agency's mail server and graded Verified (the mailbox exists), Accept-all (the server accepts any address, so it's a maybe) or Invalid (never exported). Emails come from the agency's own website, with the page each was found on.

How much does a marketing agency email list cost?

Leadraft charges one business credit per agency, once, and one checked-email credit per verified email you take out. California has about 2,460 advertising agencies with employees (Census 2023), and Google Maps will show more once you add digital, SEO and web design terms. A list of 5,000 agencies fits the Starter plan ($19 a month for 25,000 businesses and 1,000 checked emails); if you want 3,000 verified emails, Growth ($49, 5,000 checked emails) covers it in one month. The Free plan gives you 500 businesses and 50 checked emails a month to test one city first.

Do you include the agency owner's name?

No. Leadraft lists businesses, not people. You get the emails each agency publishes on its own website, often a hello@ or new business address and sometimes the founder's own, with the role and the page it was found on. The LinkedIn column links to the agency's page when it has one.
