A telephone appeal, often still called a telethon, is a structured calling campaign in which a team of trained callers, frequently your own students or younger alumni, phones supporters to reconnect, share news and invite them to give. It is one of the oldest tools in the fundraising handbook, and one a surprising number of organisations have written off too soon. Done badly, it is an intrusive cold call read off a card. Done well, it is the warmest, most human moment in your whole programme: a real conversation, with consent, between someone who cares about your cause and someone who has every reason to.

That distinction matters more than ever. In a world of one-way email and social feeds, a phone call is one of the few channels where the supporter gets to talk back. They can ask about the project, share a memory, tell you what they think, and decide on the spot whether and how much to give. A well-run appeal asks first and listens hard: supporters get the chance to opt out before any call is made, and callers are trained to recognise when not to ask. The result is not a script delivered at someone, but a genuine exchange that strengthens the relationship whether or not a gift follows.

This guide sets out how to plan and run such an appeal, with a particular focus on bringing one in-house. It draws on best practice from Hubbub's consultants and on a candid account from Katie, philanthropy officer at Benenden School, an independent girls' boarding school in the heart of Kent, who has described moving a long-running calling campaign in-house. Her experience runs through the practical sections below, because the questions she faced, how to find and train callers, what to do about a script, how to take a gift over the phone, are exactly the ones you will face too.

Why a telephone appeal still works

The case for the telephone is the case for human contact. At its best, an appeal does three things at once that few other channels manage together: it re-engages lapsed and quiet supporters, it acquires new donors, and it gathers intelligence you cannot get any other way. In Benenden's first fundraising year, callers spoke with 462 supporters and secured 108 gifts, a conversion rate of around 23 per cent of those they actually reached, and brought in an immediate pledge total of just over £39,000, rising to around £72,000 across a five-year giving cycle. The single largest gift came from a previous non-donor who pledged over £21,000, exactly the kind of person a mass email would never have surfaced.

The channel also rewards patience. Benenden's very first campaign was not a fundraising exercise at all. It was a round of "affinity calls", reaching out to alumni in the isolation of the pandemic simply to check in, with no ask made. As Katie put it, these "weren't fundraising calls but affinity calls designed to provide an emotional touch point". The goodwill that built, along with the case studies and warm feedback it produced, was what won the internal argument for a fundraising campaign the following year. If your supporters have not heard from you by phone in years, a relationship-first call can be the right way to start.

Deciding whether to run it in-house

The first strategic question is not how to run an appeal, but how much of it to run yourself. The traditional model is a fully managed campaign in which a consultancy supplies the software, employs and trains the callers, sets the ask amounts and supervises the calls. It works, and for a first campaign it is often the right choice. The trade-off is cost: a managed campaign can consume a large share of the income it raises, especially at the smaller and mid-level gift range where many telephone gifts sit.

Katie's director captured the choice with an analogy worth borrowing. A fully managed campaign, he told her, "has been the kind of chauffeur driven Rolls-Royce experience of telephone campaigns and in reality we really need to be driving a Ford Fiesta ourselves instead." His point was not that managed support is bad. It was that once a team has run a campaign or two and absorbed the know-how, it no longer needs every module. A frank cost-benefit analysis at Benenden found that monthly direct debits were "taking over two years of monthly payments to offset our consultancy costs", which made the fully managed model unsustainable for the income it produced.

The sensible path is rarely all-or-nothing. Most teams move in-house gradually, keeping specialist support for the parts that genuinely need it, such as training, call supervision and ask-setting, and bringing the rest under their own control as their confidence grows. By its fourth year Benenden ran the campaign largely in-house with a core team of one or two people, retaining external support only for caller training, and saved around £12,000 in consultancy costs in a single year. The reassuring message for small teams is that it is doable: "if you are from a small development team, it's doable, we did it, we're proof."

Planning and timeline

Treat the appeal as a project with a clear runway. Benenden's in-house campaign ran on a three-month timeline, from planning in late May to the final follow-up communications in early August, mapped out as a Gantt chart that listed "every single task from the pre-call to shortlisting applicants for recruitment". Front-loading that planning is what keeps delivery calm: decide your segments, your ask strategy and your caller numbers before recruitment opens, not while it is under way.

Two planning decisions repay early attention. The first is the pre-call mailing. Send a letter or email well in advance, around a month ahead, telling supporters the campaign is coming and, crucially, offering them the chance to opt out. This is both good practice and good fundraising: it removes the unwilling from your calling pool and leaves you with a warmer, more receptive audience. The second is your timetable for calling shifts. Build it around the realities of your callers and your audience, including time zones if your community is national or international. One of the quiet advantages of running in-house is exactly this flexibility: the freedom to let an experienced caller join for one week rather than two, or to schedule overseas calling for the weekend.

Data selection and segmentation

Your data does more to determine the result than almost anything else, so segment it deliberately. A mature appeal will call several distinct groups, and each needs its own framing: alumni, former parents who have given before, long-standing former staff, and within each of those the split between existing donors and non-donors, and between local and overseas supporters. Benenden built what the team called a "mega spreadsheet" as a low-cost alternative to specialist telethon software, with restricted access so callers could see only the people they were allocated and the relevant details about them.

Set realistic expectations from the data rather than from last year's headline figure. By its fourth year, Benenden's income was around half its early peak, not because the campaign was worse but because many of the people being called had already been phoned in previous years and were a naturally less engaged pool. As Katie noted, you "can't look at our results in comparison to the last two years and see that as we've not done as well, it's our data". Judge the campaign against the segment you are actually working, not against an unrepeatable first run.

Segmentation also opens up the single most valuable call you can make to an existing donor: the uplift ask. Asking current monthly donors to increase their gift "really needed a very detailed amount of tailoring", and Benenden put only its "most experienced and emotionally intelligent callers on that shift", briefing them one-to-one on each donor's history and current gift. The tone has to thank first and never demean the existing gift. Handled with that care, around 60 per cent of those asked to uplift gave more, and the call doubled as stewardship.

Recruiting and training callers

Your callers are the campaign. For schools and universities the natural pool is current students and recent leavers, and the most reliable way to recruit them is personal, not a mass email. Benenden's team presented in person to senior students, sat former callers on a panel to answer questions, and worked through tutors and boarding-house staff to reach students in the settings where they actually listen. Word of mouth and the chance to work alongside friends over the summer did much of the rest. Incentives help at the margins: voucher rewards, and a refer-a-friend scheme that pays out when a recommended applicant is appointed.

Two recruitment dividends are easy to underrate. The first is caller retention: a returning caller is worth far more than a new one, because in training they "took that kind of leadership role when going into the role plays", reassuring nervous first-timers with real examples. Benenden had five former callers return in its first in-house year. The second is who your callers are. Having scholarship recipients themselves on the phones was, in Katie's words, hugely valuable: "nothing was more valuable than a direct recipient of the award talking to alumni down the phone about how much of an impact" their education had had. If you run in a school, factor in the practicalities early: background and working-with-children checks, contracts and safeguarding briefings for whoever sits on the interview panel and makes the calls, and bring HR in from the start.

Training is the part most worth doing properly, and the part most teams keep external support for even after going in-house. Benenden retained Hubbub's consultancy for an in-depth, two-day training programme covering mock calls, strategies for handling objections, and setting the right tone for asking. The division of labour is a useful template: the institution briefs on its own context, the campaign, the safeguarding and the expectations of callers, while the consultant brings the fundraising craft, "how to make the successful calls" and the structure of a good conversation. Role play with experienced callers, repeated until the conversation feels familiar, is what turns an anxious student into a confident one.

The conversation and a good script

The most important lesson in this guide runs against instinct. The script is the bread and butter of a traditional telethon, but a word-for-word script is the wrong tool. Benenden's callers had been told, more than once in earlier years, "you're just reading from a script aren't you", which is the sound of a campaign failing in real time. On Hubbub's advice the team rebuilt the script as what the consultant called a "conversation guide and a safety blanket": the same clear stages as before, but guide questions rather than exact wording.

Keep the structure, lose the rigidity. A good call moves through recognisable stages: a warm introduction; a genuine conversation about the supporter's career, their memories and what they care about; news of the project or campaign you are raising for; the ask; and a soft close, whatever the answer. Letting callers find their own words at each stage is what makes the conversation "sound much more authentic" and lets the caller's genuine interest come through. Build the guide so it branches by segment, so the words flexibly fit whether the caller is speaking to an alumna, a former parent or a past donor. You do not need bespoke telethon software to do this: Benenden used Microsoft Forms, with answers merged back into its spreadsheet, and a tool like SurveyMonkey would serve as well.

To supervise the calls you need some form of call-room technology so a manager can listen in, offer real-time feedback and, where the tool allows, "whisper" advice to a caller mid-call without the supporter hearing. Benenden replaced a specialist phone app with Zoom's VoIP service. It was not perfect, carrying a three-month minimum licence for one month's use, but it came in cheaper than the alternative and did the essential jobs of monitoring, feedback and ringing the callers.

Making the ask and handling objections

The ask is where training earns its keep. The goal is an ask that "felt natural and not pushy". Callers should be taught a small ladder of asks and the fallbacks that follow, including the trade-down: dropping to a lower suggested amount or a different gift type when the first ask does not land. The trade-down works, and Benenden secured gifts through it. But the more important skill is judgement, training callers to recognise "when not to ask" and when not to be pushy. A supporter who has had a warm conversation and politely declined is still a supporter you have strengthened, and pressing them risks the relationship for a gift you were never going to get.

Structure the shifts so that confidence builds before stakes rise. Let callers warm up on more straightforward conversations before they approach higher-capacity prospects, "making sure they really felt comfortable with the ask process" first. And protect morale through the inevitable runs of voicemails and refusals. Benenden ran short pep talks before each shift, brought in guest speakers, including a scholarship recipient and a regular donor, to remind callers why the work matters, and turned the grind into games: bingo and voucher prizes that "turned a negative experience into a positive one" so a caller could win even after twenty voicemails in a row.

Tax-efficient giving

Tax-efficient giving is one of the simplest ways to add value to a telephone gift, and it belongs in the conversation rather than as an afterthought. The mechanics vary by country, so make sure your callers know the rules where your supporters are. In Canada, registered charities issue official donation receipts that donors use to claim a charitable tax credit. In Australia, gifts to organisations endorsed as deductible gift recipients (DGRs) are tax-deductible. In New Zealand, donations to approved donee organisations qualify for a donation tax credit. A telephone appeal is an ideal moment to capture the details you need for the right receipt or acknowledgment: the caller can give a plain one-line explanation, confirm the donor's contact details, and reassure them that the documentation will follow. On a five-year pledge, getting that right matters, so train your callers to handle it well every time.

Integrating with digital, regular giving and a Giving Day

A telephone appeal should never sit on its own. Its real power is as the human layer in a wider regular giving programme, and it works best when it feeds and is fed by your other channels. Most telephone gifts are best taken as a regular monthly gift, which is what builds the predictable, multi-year income a programme depends on, and the uplift ask described above only exists because previous phone pledges created donors to go back to.

The phone also pairs naturally with digital. Where a gift cannot be completed on the call, typically a single gift needing sensitive card details, the call becomes the warm introduction and a digital follow-up closes it. Benenden took regular gifts over the phone but, for overseas single gifts it could not process live, followed up through a donor engagement platform: callers recorded a short personal video with a button that took the donor straight to a donation form. Conversion on that route was harder, an honest reminder to make digital fulfilment as frictionless as you can, but the personal video clearly helped those who did complete.

A telephone appeal also sits well alongside a Giving Day. A Giving Day creates a burst of energy, urgency and match funding around a fixed window; a telephone appeal is the slower, deeper conversation that converts that attention into committed, regular donors and re-engages the supporters a Giving Day's digital push will always miss. Run in sequence, a call can thank and upgrade the donors a Giving Day acquired, while a Giving Day can re-energise the wider file the phones cannot reach in the time available.

Thanking and stewardship

Stewardship begins on the call and never really ends. The warmth that made the gift possible has to be honoured immediately: a prompt, personal thank-you confirming the pledge, the receipt or acknowledgment and what the gift will do. Remember that the uplift call is itself a stewardship act, thanking the donor and showing the impact of their support before ever raising the question of giving more.

Look after your callers with the same care. They are donors of their time, and their experience shapes both this campaign and the next. Survey them at the end, offer returning roles, and recognise the effort, not just the totals. That retention compounds: returning callers become the people who train and reassure the next intake, and the most experienced can step up into a senior caller role running the games, monitoring calls and taking the admin a one-person team cannot carry alone. A single experienced senior caller, paid a little more per hour, can be the difference between a manageable campaign and an overwhelming one.

Measuring results

Measure the appeal on more than the headline total. Track the number of supporters spoken with, the conversion rate among those you actually reached, the immediate pledge value and the full multi-year value across the giving cycle, the proportion of new donors acquired, and the uplift take-up rate among existing donors. Set these targets against the specific data you are working, not against an unrepeatable first year, and weigh them against cost: the honest measure of an in-house campaign is return on investment, not gross income. Benenden's fourth-year total of around £41,000 over five years looked smaller than its early peak, but came from a harder, much-called segment, at a fraction of the cost, with the team's own skills permanently upgraded. Capture the qualitative return too: the donor intelligence, the re-engaged supporters, and the development office's raised profile across the community are real results, even though they never show up in the income line.

Frequently asked questions

Is it worth running a telephone appeal in-house, or should we use a consultancy? For a first campaign, managed support is often the right call: it supplies the software, callers, training and supervision while you learn. As your team absorbs the know-how, you can move modules in-house to improve return on investment, typically keeping external help for training and supervision longest. Benenden saved around £12,000 in a single year by going largely in-house in its fourth year.

Should callers use a script? Keep the structure, not the script. A rigid, word-for-word script makes callers sound like they are reading, and supporters notice. Build a conversation guide instead: the same stages, introduction, conversation, project, ask, close, with guide questions rather than fixed wording, so the call sounds authentic and the caller's genuine interest comes through.

Who should make the calls? Current students and recent leavers are an ideal pool for schools and universities. Recruit them personally rather than by mass email, prioritise returning callers who can mentor newcomers, and, where you can, include people with a direct stake in the cause, such as scholarship recipients, whose own stories are powerful on the phone.

Can we offer tax-efficient giving over the phone? Yes, though the mechanics vary by country. In Canada, registered charities issue official donation receipts for a charitable tax credit; in Australia, gifts to DGR-endorsed organisations are tax-deductible; in New Zealand, donations to approved donees qualify for a donation tax credit. Capture the donor's details on the call and send the right documentation in your written follow-up, which matters over a multi-year pledge.

How does a telephone appeal fit with a Giving Day? They complement each other. A Giving Day creates urgency, match funding and a burst of digital giving; a telephone appeal converts that attention into committed regular donors and reaches the supporters a digital push misses. Run in sequence, calls can thank and upgrade Giving Day donors, while a Giving Day re-energises the wider file.

What results should we expect? It depends entirely on your data and your asks. As a guide, expect a meaningful conversion rate among supporters you actually speak to, around 23 per cent in Benenden's first fundraising year, strong new-donor acquisition, and uplift take-up of roughly 60 per cent when you ask existing donors well. Measure full multi-year pledge value and return on investment, not just the immediate total.
