5 Must-Dos for Engaging Fundraising Appeal Letters [+ Samples]

Writing a fundraising appeal letter that engages your audience and effectively raises critical donations can be daunting. Where do you even start?

Let’s back up – what do we mean by ‘fundraising appeal letter’?

In this article, we’re talking about mailed appeal letters, also known as direct mail. These letters are sent directly to potential donors on a specified mailing list, and the end goal of each is typically to raise funds for an organization’s mission. Although, you can apply many of the tips here to email appeals as well.

And, no, direct mail isn’t dead. In fact, it’s still one of the most effective ways to fundraise. Direct mail actually has an average response rate of 5.3% – compare that to the average 0.1% response rate of email appeals.

But to get to that level of response for your nonprofit, there are several key things to keep in mind. Read on for our top five must-dos when writing fundraising appeal letters!


1. Be a Friend

First up in our list of must-dos is to approach writing your fundraising appeal letter as if you are writing to a friend. You want your potential donors to feel as if they are hearing from a trusted contact, not an entire organization.


1.1 Personalize your letter

Whenever possible, include your reader’s first name, especially in the salutation. ‘Hello, Joe’ will come across a lot friendlier and establish a better relationship than ‘Dear Donor’ ever will.

You can also use more variable fields throughout your letter to restate the recipient’s name, or include details about previous gifts. Your printer can help you set up these fields.


1.2 Write with an approachable tone

This isn’t the time to pull out your dictionary or formal writing skills. Avoid jargon at all times, and write as if you are speaking to someone who knows nothing about your mission or industry. Remember, you aren’t addressing board members or staff, you’re writing to those outside of your organization.


1.3 Avoid the use of heavy design and photography

Think about it – would you include a large photo with text wrapped around it in a letter to your friend? It’s been proven that fundraising appeal letters perform better without photos because these images can make the letters feel more like a piece of marketing material than an urgent and personal ask for donations.

Save those amazing photos for places where they will have the desired impact, such as in your newsletters, annual reports, email appeals, social media posts, and website.


2. Know Your Audience

Next up, you must know and understand your audience. This will help you further personalize your fundraising appeal letter to ensure it speaks directly to your potential donors’ wants and needs.


2.1 Segment your audience

Then, create a unique letter for each segment. There are many ways to segment your contacts, including

  • Demographics (location, age, gender, etc.).
  • Giving history to your organization (amount, frequency, and favored methods of giving).
  • Preferred programs to support.

And more! On Donorbox, you can add simple as well as advanced filters to your donor data to segment them into various categories as per your need.

2.2 Target each segmented group differently

Here are a few examples of how you can best engage your different audience groups –

  • Donors who have primarily given to your food pantry in the past will likely respond best to a letter focused on the impact of that food pantry.
  • Younger donors may be more likely to respond to lower ask amounts as well as impact stories about people their age and younger.
  • Those who gave last year but unfortunately not this year (also known as LYBUNTs) will need to be targeted with a re-engagement strategy.

Donorbox reporting templates help you quickly create LYBUNT and other reports on donor data, as shown below.

2.3 Offer your audience multiple ways to give

This will ensure that each donor can make a gift in the way that is easiest for them. If you know their favored method of giving, you can highlight that method in your letter, but it’s still best to offer a variety of options, including

  • A QR code and a URL pointing to your online giving form.
  • Remittance envelops for checks or cash.
  • Phone number to call with donations or questions.

3. Engage the Reader

In order for your potential donors to read your message and, eventually, give to your cause, they must first be engaged by your fundraising appeal letter.

Start on the outside – what will get your audience to open the direct mail piece?


3.1 Design your envelope

It should catch the eye and not get tossed in the trash. Consider using a font that looks handwritten for your contacts’ addresses and be sure to include your logo.

You could also use a non-legal size envelope to draw more attention to your letter in a stack of mail, and add a quick message that hints at the contents of the letter.

Perhaps, “Open now to ensure no child goes hungry.”


3.2 Use donor-centered language

This means that you want to focus on what the recipient can do for those your nonprofit serves, instead of all that your organization accomplishes.

Make sure to balance the use of ‘you’ and ‘we’ to show that it is your donors that make the difference. “You save the lives of hundreds of area dogs with your gifts,” will resonate better than, “Our organization saved 100 dogs this month thanks to the work we put in.”

The use of bold, underlining, and italics will also keep your letter recipients engaged by moving them through the piece while drawing attention to the most important sections.

Test it out by only reading the content you highlight – will a skimmer get the whole story if they never read the entire letter? Plus, if your highlighted portions are engaging enough, someone who usually only skims may be enticed to read it all!


4. Show Impact

One of the most important things to remember when it comes to any type of fundraising is that the majority of people give to people (or animals, or places), not organizations. That’s why it is vital that you show the real impact your donors can have on the lives of others.

Let’s be honest – no one outside of your nonprofit really cares if you meet your fundraising goal or not. They want to know how meeting this goal will help those you serve.

Use storytelling to show your potential donors exactly how their gifts will make a difference. Write about a child who received critical medical care because of donations, a family that found shelter and food through your programs, or a cat that was recently adopted by her forever family.

Just make sure your stories are real and that they evoke powerful emotions – the more connected the reader feels to the story, the more likely they are to give to ensure similar stories can come true for others.

Pro tip: Some organizations are tempted to use statistics and data to show their impact in a fundraising appeal letter. We suggest sending these numbers in a separate impact report or annual report instead so that the focus of the letter can be on the story and the ask.


5. Make the Ask (More than Once)

This must-do is a big one – you must make the ask!

Too many nonprofits are uncomfortable putting a straightforward ask in their fundraising appeal letters. But your readers won’t know what you want them to do unless you tell them.

You can see the difference here:

  • “You can make a difference this giving season. Thank you for your generosity.”
  • “Your gift of $50 today ensures no child goes hungry this summer.”

Which one sounds better? If you think it’s the second one, you are correct! Your ask should be specific and actionable. Including an ask amount as well as a deadline makes it even more powerful.

Pro tip #1: Include variations of the ask multiple times throughout the appeal letter – at least two to three times – so that you are really driving the message home.

And make sure to include an ask in a P.S. Many studies have found that one of the first things an appeal recipient reads is the signer of the letter, followed immediately by the P.S. So, don’t forget to include it!

The P.S. should be a brief summary of the ask and should tell the reader exactly what the purpose of the letter is, even if they don’t read anything else.

Pro tip #2: Start by developing a case statement – also known as a case for support – targeted to your appeal, or the campaign that surrounds it. This will help you better explain your impact and purpose, as well as formulate that all-important ask.


Bonus Must-Do: Syndicate Your Content

And we have a bonus must-do – don’t stop at a fundraising appeal letter! Each appeal you write should be part of an overarching, multi-channel campaign.

It can take anywhere from 7 to 12 touchpoints before a donor decides to give. With a multi-channel campaign, your message is delivered through several different outlets, including your appeal letter, social media, email, and your website – and beyond. It ensures your donors see your message more than once and in more than one place.

The best part? You don’t have to recreate the wheel. Start by writing your fundraising appeal letter using the tips above. Then, take the best nuggets and repurpose them for use throughout your campaign’s channels.

Adjust each piece for the channel and its audience. Don’t just copy and paste. And you’re well on your way to a full-fledged fundraising campaign.
