    How it works

    You write the appeal. We make it ask better.

    You know your cause and your donors. What we know is what makes people give, and we mark up your draft until every line is doing that job.

    01

    You send your draft

    The fundraising email, letter or donation page you're about to send, or the last one you sent. Paste it or attach it. No briefing call needed.

    02

    We review it in 48 hours

    A senior expert fundraiser reviews it against our proven direct-response principles and marks every place it loses gifts.

    Sample review

    This is what comes back to you.

    A year-end email from a regional food bank, reviewed before sending. The problems are the ones we see most often.

    Note: the organisation is invented.

    Year-end appeal, 2 December

    Regional food bank · 38,000 emails
    Wonderaise review
    Subject line
    Our Year-End Campaign 2026 has started
    Before the 31st, one thing I need from you

    Why: a personal line with a date and an open question gets opened. A campaign announcement gets filed.

    First sentence
    For fifteen years, our food bank has served families across the region with dignity, through the generosity of people like you…
    On 2 January the schools reopen and 640 children in our district go back to the one meal a day they can count on. I need €42 from you before the 31st, and I'll tell you exactly where it goes.

    Why: the rewrite opens with the date, the number, the amount and a promise to explain.

    The ask
    Please consider supporting our work with a gift of €10, €25, €50, €100, €250 or €500.
    Your €42 fills one school breakfast crate: 60 breakfasts, one classroom, one week in January.

    Why: one amount, set by what this list actually gives, buying one countable thing by one date.

    P.S.
    P.S. Thank you for your continued support.
    P.S. The crates go out on 2 January. Anything that reaches me after the 31st is too late to pack.

    Why: many donors read the P.S. first. It has to carry the deadline and the ask on its own.

    The method

    The expert method behind the world's biggest fundraising programmes.

    Our fundraisers are experts in American direct response, the method refined over decades and proven on millions of appeals by the organisations that raise the most. Most donors decide in four places: the subject line, the first sentence, the ask and the P.S. That's where we start. A few of the principles we apply to every review:

    Questions

    Before you send anything.

    Do you write our appeals for us?

    No. You write the draft, because you know your cause, your donors and what's happening on the ground. We review it, annotate it and rewrite the parts that decide whether people give: the subject line, the opening, the ask and the P.S.

    What can we send?

    Fundraising is our speciality: year-end, emergency, monthly-giving, renewal and launch appeals, as emails, letters or donation pages. But we're not limited to fundraising. We also review the emails you send to get people to act or engage: petitions and campaign actions, event invitations, welcome series, newsletters and supporter updates. Send the draft before it goes out, or the last one you sent so the next one does better. Reviews come back in the language you send.

    Is our copy kept confidential?

    Yes. Your copy is used only for your review and is never shared or reused. We don't need your donor list or any donor data to do the work.
