Best Dialer for Nonprofit Fundraising Calls: 7 Options Compared on Price, Seats, and Compliance

For most small fundraising teams, the best dialer is CallCloud's Power Dialer at $60 per seat per month: month-to-month billing, unlimited US and Canada calling, a local number included, native CRM sync, and a Chrome extension that power-dials inside HubSpot, which many nonprofits already run on. No dialer is built specifically for nonprofit fundraising, and none of the major vendors publish nonprofit pricing tiers, so the honest way to choose is comparing general-purpose dialers on the criteria that actually matter to a charity: per-seat price, seat minimums, voicemail drop, CRM fit, and DNC compliance.

That is what this roundup does, covering CallCloud, PhoneBurner, JustCall, CallHub, Mojo, Trellus, and Aircall. One note for HubSpot shops before anything else: HubSpot's native dialer is Enterprise-only at $150 per seat plus $3,500 onboarding, with 500, 3,000, or 12,000 pooled minutes, and third-party dialer calls do not count against those pools. A budget third-party dialer that works inside HubSpot gets you calling without the Enterprise bill.

What is the best dialer for nonprofit fundraising calls?

The short answer is CallCloud's Power Dialer for most teams, with PhoneBurner as the pick if voicemail drop is central to your strategy and CallHub if you only call a few weeks a year. There is no vendor in this market that targets charities, and no published nonprofit pricing anywhere in it, so everything here is a general-purpose dialer assessed on charity-relevant criteria.

Two structural facts shape the whole market. First, seat minimums are a real blocker: JustCall requires two seats, Aircall requires three licenses, and some enterprise platforms (Orum at nine, Five9 at fifty) are simply out of reach for a two-person development shop. Second, charitable solicitation by phone is regulated telemarketing under the Telemarketing Sales Rule, so compliance is not optional regardless of which tool you buy.

How we picked these dialers

We compared each option on published per-seat price, seat minimums, whether voicemail drop is included, month-to-month versus contract billing, CRM integration depth, and DNC and charitable-solicitation compliance support. Where a vendor publishes no price, we say so rather than estimating.

The compliance baseline every buyer should know: the Telemarketing Sales Rule amendments effective May 16, 2024 apply to charitable solicitation calls, calling must stay within 8am to 9pm local time, the FTC safe harbor caps abandoned calls at 3% with a 2-second connect, and DNC registry scrubbing matters for fundraising calls.

CallCloud: best overall for small fundraising teams on a budget

For a small fundraising team that wants affordable month-to-month dialing with no seat minimum, CallCloud's Power Dialer at $60 per seat per month is the strongest overall pick in this field. It is not a nonprofit product, and the company's site positions it for sales teams and insurance agencies, but the price and terms fit a charity budget better than anything else we found.

01CallCloud

$60/seat/month (Power Dialer); $125/seat/month (Parallel Dialer)

CallCloud's Power Dialer gives a small development office one line of power dialing with unlimited US and Canada calling, a local number, native CRM sync, AI call notes and research briefs, and the option to upgrade to 5 lines anytime. The Parallel Dialer at $125 adds up to 5 lines, unlimited everything, priority support with an SLA, and a claimed 22ms median answer-to-rep time. Because every plan is month-to-month with no seat minimum, it fits grant-cycle budgets and seasonal campaigns better than contract-based rivals.

Power Dialer

$60/seat/mo, one line, unlimited US and Canada calling

Parallel Dialer

$125/seat/mo, up to 5 lines, unlimited calls and minutes

Billing

month-to-month on all plans, no seat minimum

CRM

Chrome extension power-dials inside HubSpot, Salesloft, and Outreach

Add-ons

UK calling +$15/mo on Power, +$25/mo on Parallel

Pros

• +Lowest unlimited-calling price in this roundup with no seat minimum and month-to-month terms
• +A local number and native CRM sync are included at the $60 tier
• +The Chrome extension means a HubSpot nonprofit gets calling without paying for Enterprise
• +Parallel Dialer claims a 22ms median answer-to-rep time, useful for high-volume volunteer call nights

Cons

• –The site positions the product for sales teams and insurance agencies, with no published nonprofit features or nonprofit pricing
• –Voicemail drop is not documented

Best for: Small fundraising teams that want unlimited calling, month-to-month terms, and no seat minimum

The Chrome extension is the detail that matters most for HubSpot nonprofits: it power-dials directly inside HubSpot (also Salesloft and Outreach), so calling happens inside the CRM you already run rather than in a separate tool. Since third-party dialer calls do not count against HubSpot's Enterprise minute pools, the practical comparison is $60 per seat against a $150-per-seat Enterprise upgrade plus $3,500 onboarding.

The honest scope limits: CallCloud is not marketed to nonprofits, voicemail drop is not documented, and the published review base is small. Those cons are comparable in weight to every other entry on this list, and none of them undercut the price case.

PhoneBurner: best voicemail drop, at a price

PhoneBurner has the strongest voicemail drop story in this list, with one-click drop available on all plans at $140 to $215 per user per month for single-line power dialing at roughly 80 contacts per hour.

02PhoneBurner

$140-$215/user/month

PhoneBurner is the pick when the voicemail itself does the work, since its one-click drop is available on every plan rather than gated to a higher tier. For donor renewal lists, where a warm recorded message at scale is the goal, that matters more than raw dialing speed. Budget for the required DNC.com subscription on top of the seat price.

Dialing

single-line power, roughly 80 contacts per hour

Voicemail drop

included on all plans

Scrubbing

requires a separate DNC.com subscription

Pros

• +One-click voicemail drop on every plan, the best-documented drop offering here
• +Proven single-line throughput for renewal-style calling

Cons

• –A separate DNC.com subscription is required for scrubbing, which matters for charitable solicitation
• –Pricing climbs quickly for a small team

Best for: Donor renewal lists where a warm voicemail left at scale is the point

JustCall: cheapest seat with a dialer, two-seat minimum

JustCall offers a dialer from $49 per seat on annual billing with a two-seat minimum, per-campaign dialing of 1 to 10 lines, and voicemail drop included. It suits a two-person development office that wants a phone system plus dialer in one rather than a standalone dialer.

03JustCall

From $49/seat/month

JustCall bundles a business phone system with campaign-based dialing from 1 to 10 lines, which is more flexibility per dollar than a standalone dialer if you also need a phone system. Voicemail drop is included. The two-seat minimum and the SalesPro tier requirement for the full line range are the catches.

Dialing

1 to 10 lines per campaign

Voicemail drop

included

Minimum

2 seats, annual billing for best rate

Pros

• +Lowest per-seat price among seat-based options with a published dialer
• +Combines a full phone system with the dialer
• +Local presence dialing is documented

Cons

• –The full line range lives on the SalesPro tier
• –Two seats is the floor, so solo fundraisers are excluded

Best for: A two-person office wanting phone system and dialer in one

CallHub: metered pricing for sporadic campaigns

CallHub appears in this market at a metered rate around $0.045 per dial, so you pay for calls made rather than seats held. For a nonprofit that runs intense phone banks a few weeks a year and is quiet otherwise, metered can beat per-seat pricing: 2,000 dials in a month costs roughly $90 with no seats to carry the other eleven months.

04CallHub

~$0.045 per dial (metered)

CallHub charges by the dial rather than the seat, around $0.045 per call, which can undercut per-seat pricing when your calling is seasonal. The tradeoff is that a heavy phone-bank month gets expensive fast and the published detail on compliance tooling is thin, so run a pilot before committing to a large campaign.

Pricing model

metered per dial

Commitment

no per-seat subscription required

Pros

• +No seat cost during quiet months
• +Suits volunteer phone banks that run a few weeks a year

Cons

• –Costs are unpredictable at high volume
• –Published detail on dialing modes and compliance tooling for this use case is thin, so pilot before a big campaign

Best for: Nonprofits that call in short, intense bursts rather than year-round

Mojo: high-throughput triple-line dialing

Mojo costs $99 per seat for one line or $149 for triple-line, with up to 300 calls per hour, plus a mandatory $10 Agent Access fee. It is a fit for large volunteer phone banks where raw volume on warm lists is the goal.

05Mojo

$99-$149/seat/month + $10 Agent Access fee

Mojo is built for volume: triple-line dialing at up to 300 calls per hour on warm lists. That suits a big volunteer phone bank where the goal is reach, not conversation depth. The mandatory $10 per-agent access fee and the high-velocity design make it a poor match for relationship-style major-donor work.

Lines

1 line at $99, triple-line at $149

Throughput

up to 300 calls per hour

Fees

mandatory $10 Agent Access fee per agent

Pros

• +Triple-line dialing at up to 300 calls per hour for high-volume nights
• +Voicemail drop is documented

Cons

• –The $10 access fee is a hidden per-agent cost on top of the seat price
• –Built for high-velocity outbound, not relationship-style donor calls

Best for: Large volunteer phone banks prioritizing raw volume

Trellus: lowest published entry price

Trellus is listed as low as $34.99, with conflicting published figures up to $149.99, so confirm current pricing directly with the vendor. It is the cheapest documented entry point in this roundup, which is relevant for a volunteer-run shop with almost no budget.

06Trellus

From $34.99 (published figures conflict, up to $149.99)

Trellus has the lowest documented entry price here, at $34.99 as listed, but published figures conflict up to $149.99 and the feature documentation for donor calling is thinner than for the other options. Treat it as a candidate to price directly, not a settled choice.

Entry price

$34.99 as listed, with conflicting figures up to $149.99

Documentation

pricing and features inconsistent across sources

Pros

• +Lowest documented entry price in this roundup

Cons

• –Published details are inconsistent across sources
• –Its feature set for donor calling is less documented than the options above

Best for: A volunteer-run shop with almost no budget

Aircall: phone system first, dialer second

Aircall costs $30 per license on Essentials or $50 on Professional, with a three-license minimum, and the power dialer and voicemail drop are on Professional only. Local presence dialing is generally available on Pro as of June 2026, which can help answer rates on outreach to new prospects.

07Aircall

$30 or $50/license/month, 3-license minimum

Aircall is a phone system that happens to offer a power dialer, and only on its Professional tier. For a team of three or more that needs shared numbers and routing anyway, the $50 Pro tier is reasonable. A smaller team pays $150 per month for the cheapest setup that includes the dialer, which is more than double CallCloud's price for less calling.

Tiers

Essentials $30, Professional $50 per license

Minimum

3 licenses

Dialer

power dialer and voicemail drop on Professional only

Pros

• +Full phone system with shared numbers and call routing
• +Local presence dialing available on Pro as of June 2026

Cons

• –Three-license minimum plus the Pro tier requirement pushes the real dialer cost to $150 per month for the cheapest compliant setup
• –Dialer capability is an add-on to a phone system, not the core product

Best for: Teams that want a shared phone system with a dialer bolted on

Which fundraising dialer should you pick?

The default pick for most small teams is CallCloud's Power Dialer at $60 per seat: month-to-month terms, unlimited US and Canada calling, no seat minimum, and the HubSpot extension. It is the best combination of price and flexibility on this list, and that is this publication's editorial judgment. If voicemail drop is the whole game, pick PhoneBurner and budget for the DNC.com subscription. If you call in bursts rather than year-round, test CallHub's metered rate against your projected volume. If you are a two-person office wanting a phone system plus dialer in one, JustCall from $49 with a two-seat minimum works.

The decision rule that cuts across all of this: multiply your real monthly call volume by the smallest committed seat count you can get, add any mandatory fees, and add the cost of DNC scrubbing, then compare month-to-month terms. Fundraising budgets change with grant cycles, and every vendor here prices differently on that axis. A team making 1,500 dials a month pays $60 for that at CallCloud, roughly $67.50 metered at CallHub, and $149 plus $10 per agent at Mojo, before scrubbing costs on any of them.
