TL;DR: The best dialer for nonprofits is decided by how you bill, not by whose feature list is longest, because the two platform families price on opposite axes. Campaign dialers charge per dial and let unlimited volunteers log in free, so as of November 7, 2026 Scale to Win runs 4 cents per outbound dial with no charge for callers or connected minutes and GetThru ThruTalk runs 4.5 cents per dial plus a one-time $300 setup fee, which puts a 30-volunteer, 20,000-dial Giving Tuesday phone bank at roughly $800 instead of a four-figure seat bill. Business phone platforms charge per seat and bundle the inbound line, texting, recording and CRM logging the same people use the other eleven months, so PhoneBurner lists $140 per user per month billed annually (Standard) up to $183 (Premium), Aircall advertises a 50 percent nonprofit discount on standard user rates valid only on an annual contract, and Kixie sells three tiers (Professional, Single-Line PowerDialer, Multi-Line PowerDialer) with unlimited US and Canada minutes, a 7-day free trial and no credit card required. Watch the caps that kill a phone bank: CallHub Essential is $0.045 per dial but stops at 10,000 contacts and 10 agents, and its Scale tier carries a $2,500 minimum commitment. On the rules, 16 CFR 310.6(a) puts charitable solicitation calls outside the national do-not-call registry provision, but 16 CFR 310.4(b)(1)(iii)(A) still binds your own entity-specific do-not-call list, 310.4(c) still holds you to 8:00 a.m. through 9:00 p.m. local time at the called party, 310.4(e) still requires the caller to name the charity and say the call is asking for a contribution, and 47 CFR 64.1200(a)(2) still requires prior express consent before an autodialer or prerecorded voice reaches a cell phone even for a tax-exempt nonprofit. Predictive dialing is where nonprofits get hurt, so if you use it, the safe harbor rule at 310.4(b)(4) caps abandonment at 3 percent of calls answered by a person. Kixie’s PowerDialer runs one line per rep at a 1:1 ratio or up to 4 lines in parallel with AI Human Voice Detection, which is a power dialer rather than a predictive dialer, so there is no abandonment rate to manage.

Most “best dialer for nonprofits” lists rank the same seven products and never ask the one question that changes the answer. How many people are calling, and for how long?

That is not a soft preference. It is the billing axis. A development director running a year-end phone bank with 30 volunteers for two weeks and a development director running six paid staff on donor calls every week of the year are not buying the same product, and the price gap between the right pick and the wrong one is not 10 percent. It is multiples.

So before the vendor demos, write down two numbers: how many humans will be logged in at once, and how many dials they will place in a year. Everything below sorts itself around those two numbers.

What nonprofit calling actually looks like

Nonprofit outbound calling comes in two shapes, and almost every organization runs one of them clearly and the other badly.

The seasonal phone bank. Giving Tuesday, a year-end push, a membership renewal drive, a get-out-the-vote style volunteer night. Headcount spikes from four to forty. The callers are volunteers who get fifteen minutes of training and may never log in again. Call volume is enormous and compressed into days. Nobody is taking inbound calls. The list comes out of the CRM as a one-time export and the dispositions go back in as a one-time import.

The year-round development desk. Four to ten paid staff. Major-donor stewardship, lapsed-donor reactivation, pledge follow-up, grant relationship calls. They also answer the phone when a donor calls back, text a donor about an event, and need every one of those touches written to the constituent record without anyone retyping it. Volume per person is modest. Continuity is the whole point.

The failure mode is predictable. An organization buys per-seat software because the development desk needs a phone system, then tries to run the November volunteer night on it and discovers that onboarding 30 volunteers means paying for 30 seats. Or it buys a per-dial campaign tool because the phone bank was cheap, then asks the development desk to live in a tool with no inbound line and no CRM write-back, and the donor history quietly stops being accurate.

You are allowed to buy both. A lot of organizations should. What you are not allowed to do is pick one and pretend it covers the other.

The rules that shape a nonprofit dialer shortlist

This section is operational information, not legal advice. Run your program past counsel before launch. But you cannot evaluate a dialer against rules you have not read, so here is what the two federal rulebooks actually say about charitable calling.

The national do-not-call registry does not reach your fundraising calls. 16 CFR 310.6(a) states plainly that solicitations to induce charitable contributions via outbound telephone calls are not covered by 310.4(b)(1)(iii)(B), which is the registry provision. The parallel FCC definition agrees: 47 CFR 64.1200(f)(15)(iii) excludes a call made by or on behalf of a tax-exempt nonprofit organization from the term “telephone solicitation.” That is the carve-out people mean when they say nonprofits are exempt.

Your own suppression list still binds you. 16 CFR 310.4(b)(1)(iii)(A) prohibits calling a person who has previously said they do not wish to receive a call made on behalf of the charitable organization for which a contribution is being solicited. And 310.4(b)(1)(ii) forbids interfering with that request in any way, including hanging up on the person, assessing a fee, requiring them to listen to a pitch first, or making them call a different number to opt out. So the dialer has to let a caller mark a record do-not-call mid-call, and the next campaign has to actually read that field.

Calling hours are 8:00 a.m. to 9:00 p.m. 16 CFR 310.4(c) sets that window by local time at the called person’s location, not yours. If your list crosses time zones and your dialer cannot schedule by the contact’s area code, your evening shift is calling someone’s house at 10 p.m.

You must identify the charity and the ask, promptly. 16 CFR 310.4(e) requires the caller to disclose truthfully, promptly and in a clear and conspicuous manner both the identity of the charitable organization and that the purpose of the call is to solicit a charitable contribution. That is a script requirement, and it belongs in the first fifteen seconds, not the last.

Cell phones still need consent for automated calls. 47 CFR 64.1200(a)(2) requires prior express written consent for an autodialer or artificial or prerecorded voice call that constitutes telemarketing, and it lowers the bar to prior express consent when the call is made by or on behalf of a tax-exempt nonprofit. Lower bar, not no bar. A live volunteer dialing manually is a different fact pattern from an automated system placing the call, so ask each vendor in writing which one their product is.

Prerecorded calls to landlines get three per 30 days. 47 CFR 64.1200(a)(3)(iv) permits a prerecorded call to a residential line by or on behalf of a tax-exempt nonprofit with no consent, provided the caller makes no more than three calls in any consecutive 30-day period to that line and honors opt-out requests. Three. Not three per campaign.

If you go predictive, the abandonment ceiling is 3 percent. A call is abandoned under 16 CFR 310.4(b)(1)(iv) when a person answers and the telemarketer does not connect them to a representative within two seconds of their completed greeting. The safe harbor at 310.4(b)(4) requires technology that holds abandonment to no more than 3 percent of all calls answered by a person, measured over a single campaign under 30 days or over each successive 30-day period, plus ringing for at least 15 seconds or four rings and retaining the records that prove it. Note that 47 CFR 64.1200(a)(7)(iv) says the FCC’s abandoned-call paragraph does not cover calls made by or on behalf of tax-exempt nonprofits, which is exactly the kind of split that makes “are we exempt” the wrong question to ask a salesperson.

Here is the practical read. Predictive dialing is the only dialing mode on this page that creates an abandonment problem. If you do not need it, not buying it removes a whole compliance workstream. Most nonprofit calling does not need it.

Best dialer for nonprofits by how you call

Every price below was read from that vendor’s own pricing page on November 7, 2026. Pricing changes, so get a written quote before you commit. The links are in the Sources section at the bottom rather than in this prose.

Scale to Win Dialer, for the big volunteer phone bank

Four cents per outbound dial as of November 7, 2026, and the page is explicit that there is no charge for the number of callers or for connected minutes. Automatic voicemail drop is listed at 1.5 cents. For a one-night phone bank that is the whole argument: you can put forty volunteers on it and pay nothing for the forty.

Run the arithmetic on a real campaign. Thirty volunteers, 20,000 dials over two weeks. At 4 cents per dial that is $800, full stop. Price the same campaign on a per-seat platform at $140 per user per month and you are at $4,200 for a single month of seats you will cancel in December.

Where it stops. It is a campaign tool. There is no bundled business phone system, no inbound desk line, no year-round CRM presence. Also check the texting side separately: Scale to Win Text is 1.5 cents per outbound SMS segment on a long code, and the short code option adds a $500 per month flat rental fee.

GetThru ThruTalk, for repeat nonprofit phone banks

GetThru publishes a dedicated nonprofit rate card. As of November 7, 2026 ThruTalk is 4.5 cents per dial with no charge for connected minutes, and ThruText is 3.5 cents per segment and 6 cents per MMS. There is a one-time $300 setup fee on all plans, and discounts appear at a $10,000 minimum commitment.

Half a cent per dial over Scale to Win sounds like nothing and mostly is. At 60,000 dials a year it is a $300 difference, which the setup fee roughly doubles. Pick between them on the texting side and on whether you want their managed sending, which the page lists at an additional 5 cents per message.

Where it stops. Same shape as Scale to Win. Campaign infrastructure, not a phone system.

CallHub, for mixed calling and texting campaigns, with a cap to watch

As of November 7, 2026 CallHub Essential is pay-as-you-go at $0.045 per dial, $0.019 per SMS segment, $0.048 per MMS message, $0.046 per minute of voice broadcast, and $0.026 per minute of inbound calling, with $6 in free credits to start. Essential also includes automated litigator and cellphone scrub, which is a genuinely useful thing to get at the entry tier.

Read the Essential limits before you plan the phone bank. Up to 10,000 contacts, up to 10 agents, no sub-accounts. A 30-volunteer night does not fit. Moving to Scale lifts contacts, agents and sub-accounts to unlimited and adds Dynamic Caller ID and a dedicated success manager, but the page states a $2,500 minimum commitment and quotes custom volume rates from there. That is a real number to put in the budget conversation, not a footnote.

Kixie, for the development desk that calls all year

Kixie is a sales engagement and business calling and texting platform, and that is the reason to shortlist it here rather than for a one-night phone bank. It sells three tiers: Professional, Single-Line PowerDialer, and Multi-Line PowerDialer. All three include business phone service, bi-directional CRM integration, text messaging, SMS templates, Voicemail Drop, Live Call Coaching, call recording, IVR auto-attendant, ring groups, call queues, rule-based routing, a developer API, and unlimited minutes for calls in the US and Canada. The trial is 7 days with no credit card required.

The dialing mode matters for the compliance section above. Kixie’s PowerDialer is a power dialer, not a predictive dialer. Kixie’s own feature page describes a 1:1 ratio where the system waits for the current call to finish before dialing the next number, and the Multi-Line tier dials up to 4 numbers in parallel with AI Human Voice Detection. No algorithm is guessing when a caller will be free, so there is no abandonment percentage to measure and no 310.4(b)(4) safe harbor to document.

Two other pieces earn their place on a nonprofit shortlist. The DNC add-on supports checks against the National Do Not Call Registry and your internal suppression lists, which is the 310.4(b)(1)(iii)(A) obligation above and which runs on its own refresh clock, and Kixie’s own page is clear that customers remain responsible for their calling practices and legal review. ConnectionBoost combines local presence, number monitoring and progressive caller ID to help manage outbound number reputation and pickup rates, which matters when a donor list has been dialed by three vendors before you. The rules on displaying a local number are worth reading before you switch it on for donor calls.

Where it stops. It is priced per seat. Thirty volunteers for one night means thirty seats for one month, and that is the wrong instrument for that job. Kixie does not publish a nonprofit discount on its pricing page, so if you need one, ask for it in writing rather than assuming it. And like every platform here, it is calling and texting infrastructure, not a donor database, so your CRM stays the system of record.

PhoneBurner, for a single-line Salesforce-shaped desk

Published per-seat pricing, which is rarer than it should be. As of November 7, 2026 Standard is $140 per user per month billed annually or $165 billed monthly. Professional is $165 annually or $195 monthly and adds softphone dialing, live call monitoring and coaching, and an open API. Premium is $183 annually or $215 monthly and adds a PhoneBurner number, custom inbound routing, in-app callback answering, call transcription, and SMS messaging subject to carrier approval. SMS beyond the plan’s monthly outbound limit is an additional $15 per 1,000 messages.

The honest comparison against Kixie is the line count. PhoneBurner’s published plans are single-line dialing. If your constraint is caller time rather than list size, parallel lines are the lever, and that is a Multi-Line PowerDialer conversation.

Aircall, for the nonprofit that wants the discount in writing

Aircall runs a dedicated nonprofit program and, as of November 7, 2026, states that eligible nonprofit organizations receive a 50 percent discount on standard user rates. The footnote on that page is the part to read: the program is valid only for an annual contract. So the discount is real and the commitment is real, and a seasonal program that wants to switch off in January is paying for twelve months either way.

Pricing math for the best dialer for nonprofits

The comparison everyone botches is per-dial against per-seat, because they are not measuring the same thing.

Per-dial pricing buys you dials. Scale: 60,000 dials a year at GetThru’s 4.5 cents is $2,700, plus the $300 setup, so $3,000. Six seats on a $140 per user per month annual plan is $10,080 for the same year. On dial cost alone, per-dial wins and it is not close.

Per-seat pricing buys you a phone system. That $10,080 also covers the inbound line the donor calls back on, the texting the same staff use for event reminders, the recordings a manager reviews, and the CRM write-back that keeps the constituent record accurate without anyone retyping a disposition. Price those separately on the campaign tool and the gap closes fast, because you are now buying two products.

So the rule is simple. If the callers are temporary and the only output is a disposition, buy dials. If the callers are staff who also answer the phone, text donors, and need every touch logged, buy a phone system. If you genuinely do both, buy both and stop trying to make one tool carry the other.

One more number to put in the model: the dormant seat. Ask every per-seat vendor what happens to a seat in the eight months you are not running a phone bank, and get the answer in the quote rather than from a sales call.

A donor call script that satisfies the disclosure rule

The 310.4(e) disclosure is not a legal footnote you bolt on at the end. It is the opening of the call. Here is the shape, with the required elements marked.

Opening, first fifteen seconds. “Hi, is this [Donor first name]? My name is [Caller first name] and I’m calling from [full legal name of the charitable organization]. I’m calling today to ask for your support for [specific program or campaign]. Do you have two minutes?”

That single opening carries both required disclosures: the identity of the charitable organization, and that the purpose of the call is to solicit a charitable contribution. Volunteers skip the second half constantly because it feels blunt. Keep it. It is the part the rule names.

If the donor says now is not a good time. “No problem at all. Is there a better time this week, or would you rather I send you the details by email?” Log the callback time as a field, not as a note, so the next campaign can schedule against it.

If the donor asks to stop being called. “Absolutely, I’ll take you off our calling list right now.” Mark the do-not-call field before you hang up. Do not ask why, do not pitch once more, do not route them to another number. 310.4(b)(1)(ii) names every one of those as interference with the request.

Lapsed-donor variation, for someone who gave two years ago and not since. “Hi [Donor first name], this is [Caller first name] from [organization]. You supported [program] back in [year] and I’m calling to ask if you’d consider renewing that support this year. Before I do, can I ask what made you give the first time?” The question is doing real work. A lapsed donor who tells you why they gave has just handed the next caller a better opening than any script would.

Volunteer shift confirmation, which is not a solicitation. “Hi [Name], it’s [Caller] from [organization], just confirming you’re still good for the [day] shift at [location]. Anything you need from us before then?” If the call does not ask for a contribution, the 310.4(e) solicitation disclosure is not the operative requirement, but keep the organization identification anyway. People hang up on callers who will not say where they are from.

Text follow-up after a pledge, with opt-out. “Thanks for your pledge of $[amount] to [organization], [first name]. Here’s the link to complete it: [link]. Reply STOP to opt out of texts.” The STOP line is not decoration. Honor it in the same field your dialer reads, so a donor who opts out of texts does not get called by the next campaign under a different suppression list.

Running a nonprofit calling campaign in Kixie

If Kixie is the pick for your development desk, the setup follows the workflow above rather than the feature list.

Start with the list, not the dialer. Export from the CRM with the suppression field already applied, because a scrub you run inside the calling tool only protects the campaign you are running right now. Kixie’s DNC add-on supports checks against the National Do Not Call Registry and your internal suppression lists, and your CRM keeps the authoritative version of who asked you to stop.

Build the calling session next. Single-Line PowerDialer advances one record at a time, which is the mode for major-donor and stewardship calls where the caller needs to read the history before the line connects. Multi-Line PowerDialer dials up to 4 numbers in parallel with AI Human Voice Detection, which is the mode for high-volume renewal or reactivation lists where the constraint is caller time rather than preparation.

Record the Voicemail Drop in the actual caller’s voice, not a generic one. A donor who has spoken to the same development officer twice will notice, and dropping a prerecorded message after an unanswered live dial is a different thing from an automated prerecorded campaign under 64.1200(a)(3). Keep that distinction straight with counsel before you scale it.

Set the dispositions before the first call block, not after. Pledged, declined, callback requested, wrong number, do-not-call. Five fields a volunteer can pick in two seconds beat twenty a volunteer will guess at. Calls, texts, outcomes and recordings log to the CRM automatically, so the value of the disposition list is entirely in whether someone designed it.

Then inspect the right number. Not dials. Look at the ratio of live conversations to dials, the median time between a callback request and the actual callback, and how many records closed out as no-response with only one attempt. That last one is where most nonprofit calling programs are losing money, and no dialer fixes it for you.

Nonprofit dialer questions

What is the best dialer for nonprofits on a small budget

If the calling is seasonal and volunteer-driven, a per-dial campaign tool is almost always cheaper, because you pay for dials rather than for people. As of November 7, 2026 Scale to Win lists 4 cents per outbound dial with no per-caller charge and GetThru ThruTalk lists 4.5 cents plus a one-time $300 setup. If the calling is year-round and the same staff answer inbound calls, the per-seat phone system is the cheaper total because you are not also paying for a separate phone line.

Are nonprofits exempt from the national do-not-call registry

For their own charitable solicitation calls, largely yes. 16 CFR 310.6(a) states that solicitations to induce charitable contributions by outbound telephone call are not covered by the registry provision at 310.4(b)(1)(iii)(B), and 47 CFR 64.1200(f)(15)(iii) excludes calls by or on behalf of a tax-exempt nonprofit from the definition of telephone solicitation. The entity-specific do-not-call obligation at 310.4(b)(1)(iii)(A) is separate and still applies, so your own suppression list is not optional. Confirm the analysis for your organization with counsel, and note that state charitable solicitation rules sit on top of the federal ones.

For an autodialed or prerecorded call, yes. 47 CFR 64.1200(a)(2) requires prior express written consent for a telemarketing call using an automatic telephone dialing system or an artificial or prerecorded voice, and reduces that to prior express consent when the call is made by or on behalf of a tax-exempt nonprofit. The exemption changes the form of the consent, not the need for it. The wider consent and opt-out rules moved in 2026, so check the current text rather than an old summary. Whether a given product is an autodialer within the rule is a question for counsel and for the vendor in writing.

Can a nonprofit use a predictive dialer for donor calls

It can, and it takes on an obligation by doing so. The safe harbor at 16 CFR 310.4(b)(4) requires technology that holds abandonment to no more than 3 percent of calls answered by a person, at least 15 seconds or four rings before disconnecting, a recorded identification message when no representative is free within two seconds, and retained records proving all of it. A power dialer running one line per caller has no abandonment rate to manage, which is why most nonprofit programs that do the math stay with power dialing.

Which dialer works with nonprofit CRMs like Raiser’s Edge or Bloomerang

Do not take the logo wall as proof. Ask each vendor which specific objects and fields sync, in which direction, how often, and who configures it, then test the round trip with ten real records before you sign. A marketplace listing tells you a connection exists. It does not tell you whether a disposition written on the call lands on the constituent record your gift officer reads tomorrow.

How many dials should one caller place per hour

Set the target from your own first campaign rather than from a vendor’s number. Run a short block, count live conversations against dials, and use that ratio to size the next one. Any figure a salesperson quotes is from a list, a time zone and a caller profile that are not yours.
