Official NationBuilder Integration Partner | Built for the 2026 Midterms
NationBuilder Runs Your Campaign. CallHub Runs Your Ground Game. Together, You Win Your Midterm.
NationBuilder gives you the voter file, the website, and the email engine, making it the political campaign software that campaigns trust for data and organizing. But it does not give you predictive dialer software, a political texting platform, voice broadcasting software, or a compliance layer built for high-volume political outreach. CallHub is the voter outreach software that adds every missing channel and every conversation syncs back to your NationBuilder database in real time. Your data gets smarter. Your targeting gets sharper. Your ground game gets faster. Every single day until November.

Three Gaps That Cost NationBuilder Campaigns Races
Your NationBuilder Data Is a Weapon. But Without the Best Political Campaign Software to Deploy It, You’re Bringing a Voter File to a Ground War.
NationBuilder gives you the operating system. CallHub gives you the campaign management software that executes your outreach. These are the three operational gaps that separate campaigns that win midterms from campaigns that almost did, and how the NationBuilder integration closes each one.
You Have 200,000 Modeled Targets. No Campaign Dialer to Reach Them.
Your Problem
NationBuilder stores your voter file, your tags, and your support levels. But it has no phone banking software, no predictive dialer, no power dialer, no auto dialer for political campaigns, and no voice broadcasting software. Your volunteers are hand-dialing from personal phones. Without virtual phone banking capability, you are stuck running a manual phone bank political campaign. At that pace, you will reach 3% of your persuasion universe before Election Day. NationBuilder phone banking requires a dedicated campaign dialer, and NationBuilder does not include one.
The Fix
Predictive Dialer Software, Campaign Dialer Solutions, and Voice Broadcasting, All Connected to NationBuilder. CallHub is the political dialer software that imports your NationBuilder lists and launches them through TCPA compliant dialer modes, predictive for GOTV volume, power for persuasion conversations, preview for high-value targets. As a TCPA compliant predictive dialer, CallHub’s system is SHAKEN/STIR verified. Dynamic caller ID displays a local number that is 4X more likely to be answered. Our voice broadcasting software delivers pre-recorded messages to thousands in seconds with press-1 transfer to live agents, the compliant alternative to political robo calls. Whether you need GOTV calling software for the final sprint or political campaign calling software for year-round organizing, CallHub is the campaign calling software that integrates natively with NationBuilder.
What You Get
100,000+ Voter Contacts in the Final 60 Days. Logged. Tagged. Synced. Campaigns using CallHub’s best predictive dialer software and campaign dialer solutions reach hundreds of thousands of voters in half the time of manual dialing. Every call disposition, survey response, and supporter level writes back to NationBuilder automatically. Your voter file gets smarter with every dial. Whether you need GOTV phone banking software for Election Day surges or virtual phone bank software for remote volunteer operations, CallHub’s political phone banking tools scale with your campaign.

Your Texting Is One-Dimensional. Your Opponents Are Running Political Peer to Peer Texting.
Your Problem
NationBuilder includes basic text messaging for political campaign communications, blasts, and simple targeting. But it does not offer peer to peer texting software with conversational workflows, MMS with images and video, automated political SMS with URL tracking and auto-responses, or the compliance infrastructure that keeps high-volume political campaign SMS from being filtered. Your opponent is running peer to peer texting political campaigns with 500 volunteers. You are sending one-way blasts. Without a dedicated political texting platform, you are losing the texting war.
The Fix
Full Political Campaign Texting Software: Mass Texting, P2P Texting Platform, MMS, Video Texting, Auto-Responses. 10DLC Registered. CallHub is the campaign SMS software that adds broadcast SMS with URL tracking and auto-responses, political peer to peer texting with templates and profanity filters, MMS messaging with up to 1,600 characters plus media, and video texting. As a p2p texting platform for political organizations, CallHub handles peer to peer texting for political campaigns at scale. All channels are 10DLC registered through CallHub’s official Campaign Registry partnership, meaning your political SMS marketing messages reach inboxes, not spam folders. CallHub is the political campaign texting service that treats NationBuilder texting as a native workflow, not an afterthought.
What You Get
Five Texting Channels Where You Had One. Compliant. Deliverable. Synced. Personalized GOTV texting follow-ups via P2P texting for GOTV. P2P texting GOTV workflows power peer to peer texting GOTV at scale. Polling location reminders via mass texting for political campaigns. Candidate video messages via MMS. Barrier-solving conversations ride to polls, mail ballot questions via P2P texting voter outreach workflows. Every opt-out, response, and click is tracked and synced to NationBuilder. Whether you need voter outreach texting, SMS political campaign software, or a dedicated political campaign texting software solution, CallHub delivers it all, integrated directly with your NationBuilder voter file.

Your Tools Don’t Talk to Each Other. Your Targeting Pays the Price.
Your Problem
You export a list from NationBuilder. Volunteers make calls in a separate tool. Results sit in a spreadsheet. Someone manually re-imports the data two days later. By then, your targeting is stale, you are calling voters who already said yes, missing voters who just moved to undecided, and wasting volunteer hours on contacts who asked to be removed.
The Fix
Bi-Directional NationBuilder Sync. Tags, Surveys, Notes, Supporter Levels, All Flowing Back in Real Time. CallHub’s NationBuilder integration is not a one-way export. Every call disposition, text response, survey answer, supporter level, tag, note, call recording, and event RSVP writes back to NationBuilder automatically. Your volunteer in Ohio tags a voter as “supporter” at 2:00 PM; your NationBuilder database reflects it at 2:01 PM.
What You Get
A Voter File That Gets Smarter Every Hour. Automatically. No CSV exports. No manual re-imports. No two-day lag. Every conversation refines your targeting in real time so your next wave of calls and texts hits a sharper universe than the last. In the final 10 days of a midterm, that compounding intelligence is the difference between guessing and knowing.

Winning Stories from Real Campaigns
We couldn’t have hit our goals without CallHub. When other platforms were struggling, CallHub was a trusted partner who could easily scale up quickly when needed. Even more, CallHub could handle our small program needs across all channels; from texting 5 people to calling 5 million, we could trust CallHub.
Cost is one. We also really liked the user friendliness of CallHub on the agent side. We had consistent feedback from all kinds of volunteers of all ages and all abilities across the country that it was just really easy to use.

CallHub has become my go-to platform for affordable phone canvassing campaigns, voice broadcasts and text message blasts. In particular, text message blasts are the single most useful tool for volunteer mobilization that I have used in recent years.
The Questions NationBuilder Campaigns Ask Before Adding CallHub
1. We already have NationBuilder set up. How hard is the integration?
It is a direct, native NationBuilder integration, not a Zapier workaround or a CSV export. You connect your NationBuilder account to CallHub, import your lists and surveys, and start dialing or texting. Survey responses, tags, notes, supporter levels, and RSVPs sync back to NationBuilder automatically. Most campaigns are running their first CallHub campaign within days of connecting the integration.
2. We have 300 volunteers. Can they all use CallHub?
Yes, unlimited volunteer accounts, no per-seat charges. Every phone bank volunteer logs in through a browser or downloads the mobile app. They see the script, the survey, and the contact. They call or text. Every response syncs to NationBuilder. Campaign managers can monitor live calls, review recordings, and track volunteer performance from the analytics dashboard.
3. We’re worried about 10DLC and TCPA compliance. Does CallHub handle that?
CallHub is TCPA compliant dialer software built for political outreach and an official Campaign Registry (TCR) partner that handles 10DLC brand and campaign registration directly. Our dialers are TCPA-compliant; they do not use random or sequential number generators. Voice calling is SHAKEN/STIR verified, giving your calls a “Caller Verified” badge that improves answer rates. The spam-label shield actively protects your caller ID reputation. You do not need a separate compliance vendor.
4. What if the data doesn’t sync correctly?
The NationBuilder integration is bi-directional and tested across hundreds of NationBuilder campaigns. Tags, supporter levels, survey responses, notes, call recordings, and event RSVPs flow back in real time. During your onboarding call, we will run a live sync test with your NationBuilder instance so you can verify the data flow before launching any voter contact campaign.
5. Can we be up and running before September 2026?
Yes. Typical onboarding from contract to first campaign launch is 5–10 business days, including 10DLC registration. If you start the process by July 2026, you will have a fully operational multi-channel voter contact program with months of runway before the November sprint. The earlier you start, the more intelligence your NationBuilder database accumulates before the final GOTV push.
6. We also need door to door canvassing and fundraising tools. Does CallHub cover that?
CallHub’s door to door canvassing software lets field teams collect survey data on mobile devices that syncs directly with NationBuilder, the same real-time sync as calling and texting. For fundraising, CallHub’s phone banking tools support political campaign fundraising software use cases, including donation asks with call dispositions and pledge tracking that write back to NationBuilder. Whether you are running a democratic campaign software stack or a nonpartisan advocacy operation, CallHub’s political canvassing software and phone banking tools integrate with NationBuilder to cover your full ground game, doors, phones, and texts.
Your NationBuilder Data Can Win This Midterm. But Only If You Can Reach Every Voter Before November.
NationBuilder is your campaign’s operating system. CallHub is the political campaign management software and voter outreach software that turns your voter file into live conversations, targeted texts, and GOTV surges across every channel that matters. The 2026 midterms will not wait. Neither should your ground game.
