Business Services Mailing Lists

Agencies, consultancies, staffing firms and professional-services leaders in one verified file.

Industry overview

Why this list works

Business services is the connective tissue of the economy — marketing agencies, consultancies, law firms, staffing companies, facilities and outsourcing providers. Our business-services database organises this diverse market by service line and firm size, with contacts at partner, practice-lead and operations level.

It's the file of choice for software vendors selling to agencies and firms, and for companies that partner with or sell through the services channel.

Our process

How we build your business services list

Brief & scoping

We capture your target titles, geographies, firmographics and exclusions in a short brief, and confirm counts before any work starts.

Sourcing & matching

Records are pulled from our contact graph, event registrations and industry registries, then matched and deduplicated against your suppression lists.

Six-step verification

Syntax, domain, mailbox, phone, web-presence and human-review checks filter the file. Anything that fails is removed, not padded back in.

Delivery & guarantee

You receive CSV/Excel within 24–48 hours with a match report — and replacement credit for any contact that fails our deliverability guarantee.

FAQ

Frequently asked questions

How current is the Business Services database?

Every record in the business services file is re-verified on a rolling 90-day cycle using email, phone and web-presence checks. Contacts that change jobs, bounce or go stale are corrected or removed before the next delivery, so the 5.3M+ figure reflects live, reachable contacts — not historical volume.

Can I select specific job titles, regions or company sizes?

Yes — that's the default way we work. Tell us the titles, seniority levels, countries or states, revenue bands and employee ranges you care about, and we cut the file to match. You can also exclude existing customers or competitors by supplying a suppression list.

What format is the list delivered in, and how fast?

Lists ship as CSV or Excel with your chosen fields, typically within 24 hours for standard selections and 48 hours for complex custom builds. Files import directly into any CRM or outreach platform — Salesforce, HubSpot, Zoho, Outreach and others.

Is the data compliant to use for marketing?

All records are business contacts collected on an opt-in, permission basis and screened against GDPR, CAN-SPAM and CCPA requirements. We also honour opt-out requests continuously, so the file you receive is safe to use for lawful B2B outreach.

What happens if some emails bounce?

We stand behind a deliverability guarantee: if hard-bounce rates exceed the threshold in your order, we replace those contacts free of charge. In practice, our six-step verification keeps typical bounce rates under 2–3%.
