What Is the Build-a-List Tool?

Our Build-a-List service is an email list builder that lets you request a custom email list matched to your ideal customer profile and build a targeted email list around exactly the audience you need. Instead of purchasing a pre-packaged custom email database, you specify the exact criteria — such as industry vertical, professional title, geographic region, and organizational headcount — and our team assembles a bespoke email database from our pool of over four million verified contacts.

The process works as a custom data request. You submit your targeting preferences through the form below, and our data specialists assemble a filtered email database that reflects those selections. We apply multi filter email list logic so you can stack parameters together — combining seniority level with technology stack, or pairing annual revenue with employee count — to produce a micro targeted email list that precisely matches the audience your outreach campaign is designed to reach and convert over time. Delivery typically takes 48 hours for standard builds — our 48 hour delivery custom list option covers most orders — and a same day custom email list turnaround is available for urgent campaigns requiring immediate deployment.

Every custom B2B data file goes through our full SMTP verification pipeline before handoff, allowing you to create custom contact database files with confidence. You receive the finished dataset as a CSV or XLSX download containing verified email addresses, phone numbers, company names, and all requested segmentation fields. This custom data build approach works well for teams that need a tailored email list without committing to a broad package, and it pairs naturally with account-based marketing strategies where your ideal customer profile drives every decision in the outreach funnel.

Why Choose a Custom Email List

Pre-built databases work well for broad campaigns, but teams running account-based strategies or entering unfamiliar verticals often need a custom list shaped around their specific audience. Here is why our on-demand approach delivers better results.

🎯

ICP-Based Precision

An ICP-based email list ensures every contact matches your ideal customer profile. By combining firmographic, technographic, and role-based criteria, you eliminate irrelevant records and focus spend on the prospects most likely to convert into pipeline.

🔀

Multi-Filter Combinations

Our multi-filter email list approach lets you stack parameters. Target CFOs at mid-market SaaS companies in the United States — or marketing directors at healthcare firms with over 500 employees. This advanced capability goes far beyond what static packages can deliver.

Fast Turnaround

Standard custom builds ship within 48 hours of approval. Need records faster? Our same-day option delivers verified contacts within business hours. Every order receives full SMTP verification regardless of turnaround speed, protecting your deliverability and sender reputation.

📞

Phone Numbers Included

Each custom email list with phone numbers adds direct-dial numbers where available. Multi-channel outreach combining email and phone consistently outperforms single-channel campaigns, giving your SDR team more touchpoints to start conversations.

💡

Niche Targeting Capability

Building a niche email list for a specialized vertical or emerging segment is where our service excels. Whether you are entering a new geography, testing a micro-segment, or enriching existing CRM data with net-new contacts, tailored builds give you control at a granular level.

💰

Transparent Quote Pricing

Every request receives a clear quote before you commit. Pricing reflects volume, complexity, and delivery speed with no hidden fees or recurring subscriptions. This on-demand model lets you build email lists at your own pace and request data only when you need it.

Build-a-List FAQ

Answers to frequent questions about targeting options, delivery timelines, data quality standards, and the process of building verified B2B contact lists around your specific audience.

How does the custom list builder tool work?+

Our list builder tool lets you define exact targeting criteria through the form. Specify your preferred country, industry, job title, seniority level, company size, revenue bracket, and technology stack. Once submitted, our data team assembles a custom contact list from our verified pool of over four million B2B records. You receive a personalized quote within hours, and delivery follows within 48 hours after approval.

What filters can I use to build a B2B list?+

You can combine nine core dimensions: geographic location, industry vertical, professional job title, seniority level, company size by headcount, annual revenue range, employee count brackets, technology stack, and data field preferences. This multi-filter approach means you can stack parameters for granular results — for example, targeting VP-level contacts at mid-market healthcare companies in the United States that use Salesforce.

What is the typical turnaround from approval to download?+

Standard builds follow a 48-hour delivery timeline after quote approval. If you need records sooner, our same-day custom email list option is available for rush orders placed during business hours. Every file goes through full SMTP verification regardless of speed, so quality remains consistent whether you choose standard or expedited turnaround.

Can I add direct-dial numbers to my custom build?+

Yes. You can request a custom email list with phone numbers by checking the phone field option in the form. Direct-dial numbers are appended where available in our database, enabling multi-channel outreach that combines email prospecting with phone follow-ups. This approach is widely used by SDR teams and sales organizations running blended cadences.

What details appear in the pricing breakdown you send back?+

Your custom email list quote breaks down estimated record counts, per-contact pricing, included data fields, file format options (CSV or XLSX), delivery timeline, and any applicable rush fees. We also note the match rate against your specified criteria so you understand exactly what to expect. There is no obligation — quotes are free and carry no commitment until you approve the order.

Do you handle hard-to-find verticals and specialized segments?+

Absolutely. Our custom data request process handles niche segments that standard packages do not cover. Whether you need contacts in emerging verticals, sub-industries, or very specific technology niches, our team can search the database for matching records. You can build your own email list around virtually any criteria as long as the contacts exist within our verified four-million-record pool.

Why do campaigns perform better when data matches your buyer persona?+

An ideal customer profile email list focuses every record on the firmographic and demographic traits that historically drive your best conversions. Instead of blasting a broad audience, an ICP-based email list narrows scope to companies matching your sweetspot size, industry, and buyer persona. Campaigns built around this method consistently see higher open rates, better reply rates, and stronger pipeline generation.

How few contacts can I order for a pilot test?+

Our minimum custom data build starts at 500 contacts. This makes the service accessible for teams testing a new segment or running a focused pilot campaign before scaling. Larger volumes — up to 50,000 contacts and beyond — are available, and per-record pricing drops as quantity increases. Submit your request through the form to receive accurate volume and pricing details.

Are postal addresses available alongside email for physical mailers?+

Yes. While our primary focus is digital outreach, our custom mailing list data includes physical business addresses where available. If your campaign strategy involves direct mail alongside email, simply note that in the additional requirements field when submitting your build request. We will include postal addresses along with standard email, phone, and company fields.

What quality checks happen before my file ships?+

Every record in your custom lead list passes our full five-step SMTP verification pipeline: source validation, MX record checks, live SMTP handshake, spam-trap filtering, and deduplication. We maintain a 95%+ deliverability guarantee on all custom builds. This verification standard applies equally to standard and rush orders, ensuring your database arrives clean and ready to deploy.

Which file types and column structures ship with completed orders?+

Custom builds arrive in your choice of CSV or XLSX format, pre-structured for direct CRM import. Column headers map to standard field names recognized by Salesforce, HubSpot, Pipedrive, and other major platforms. Each row contains the requested data fields — email, name, company, title, phone, and any additional columns — so you can create your workflow without reformatting.

Does the builder support multi-region orders spanning several geographies?+

Yes. Select "Multiple Countries" in the location field and specify which markets you need in the notes section. Our list builder supports multi-region builds that pull verified contacts from any combination of our 11+ covered countries. This is ideal for teams running international campaigns or expanding into new territories.
