THE PROBLEM
Your contacts are out there. Getting to them shouldn’t take days...or a compliance headache.
Most orgs spend more time sourcing, cleaning, and clearing data than actually running outreach. That’s backwards and avoidable.
Broken third-party lists
Stale data, unknown accuracy, manual CSV cleanup before you can even start.
Importing wrong audience
Generic lists waste budget on the wrong ZIP codes, wrong party affiliation, wrong age group.
Days before you can call anyone
Sourcing → cleaning → formatting → importing → fixing duplicates. Hours become days.

TESTIMONIALS
Hear it from the field
“A lot of our folks are volunteers, a lot of them are retired, they are often anxious with technology … It’s empowering for volunteers who don’t see themselves as very tech-savvy to be able to pick [CallHub] and a new program and just use it!”
Celine Trojand
Organizing for Change
“When other platforms were struggling, CallHub was a trusted partner who could easily scale up quickly when needed… from texting 5 people to calling 5 million, we could trust CallHub.”
John Robinson
Bernie 2020
“CallHub is my go-to platform for affordable phone canvassing, voice broadcasts, and text message blasts. The text message blasts are the most useful tool for volunteer mobilization.”
John Roche
Green Party of Prince Edward Island
“We can make calls at about 5x the rate that we would with a manual dialer, getting through a list of 100 calls in just over an hour. This has been a huge capacity saver in our organization.”
Amanda Destefano
United Workers Union
“Nationbuilder integration is awesome, particularly for SMS and for making calls to recruit volunteers. The development team is very responsive to questions and feature requests, too.”

FAQs
What is List Builder?
List Builder lets you search, filter, and import contacts directly into CallHub. Build targeted lists without leaving the platform or juggling a separate vendor tool.
Where does the data come from?
List Builder is powered by a trusted third-party national contact database that’s embedded directly in CallHub, so there’s no separate tool or export process to manage.
What can I filter by?
900+ filters across geography, demographics, voting history, and party affiliation. Preview your contact count in real time as you narrow it down.
Do I need to map fields myself?
No. Contacts map to CallHub’s native fields automatically the moment you import, so there’s no manual spreadsheet matching to get right.
How does the list get into CallHub after I build it?
Once you import your list, it lands directly as a contact list inside CallHub, ready to be used in calling, texting, or any campaign. No reformatting needed.
What's the difference between List Builder and uploading my own CSV?
Uploading a CSV means you’re relying on data you already have, which can be outdated or incomplete. List Builder pulls from a regularly updated database from a trusted data partner, so your contacts are fresher and more reliable.
How does pricing work?
One flat rate: 2.9 cents per contact. This includes 300+ exportable columns, such as landline, cell phone, name, and other core contact details.
Is this data compliant to use?
Yes. Before you can export, you’ll confirm your organization’s authorized use case and accept the usage agreement. The check runs automatically before the data leaves the platform.
Why do I need to confirm a use case?
This kind of contact data comes with usage restrictions. The compliance step protects you and CallHub by confirming that your use case, whether political, nonprofit, advocacy, or labor, meets those terms.
Who is List Builder for?
Political campaigns, nonprofits, advocacy groups, and workplace organizers who need targeted, accurate contact lists for outreach.
How current is the data?
It updates every 30 days, so it stays fresh.
