Writing a sponsor appreciation letter is an important way to thank those individuals and organizations who have supported your cause or project. It’s also an effective way to build relationships with a sponsor for future collaborations.

The process of writing a sponsorship appreciation letter can be daunting, but it doesn’t have to be! In this blog, we’ll provide tips on how to craft the perfect sponsor appreciation letter, as well as seven easily customizable, thank you letter templates that you can use as starting points. With these tools in hand, you’ll be able to easily create heartfelt messages of thanks that will make those who offer you a sponsorship feel appreciated and valued.

What is a sponsor appreciation letter?

A sponsor appreciation letter is exactly what it sounds like – it is a letter that you, as a non-profit organization, send to a sponsor or donor. A thanking letter to a sponsor can be sent for a litany of reasons – gratitude for a large donation, thanking them for being a long-term, recurring donor, or other reasons.

Many non-profits struggle to understand the benefits of consistently reaching out to donors and thanking them for their investment of time and money. Similarly, many also struggle to craft well-written, concise letters.

So, let’s break down these points one by one, starting with the importance of thanking your sponsors for their donations.

Why it’s important to thank sponsors

As a nonprofit, odds are high that you rely on the financial resources and support of donors in order to move your organization forward and to have the impact on the world that you hope and strive to. Due to this, having good relationships with all of your sponsors is crucial.

By leaving a positive impression on those who you interact with, whether it’s thanking them for a generous monetary donation, or just expressing that you are grateful for them investing their time and money into you, they will be extremely thankful for the fact that you took the time to reach out to them and thank them.

Not only will this build a bit of comradery between you and your sponsors, but it will also make them more likely to be a sponsor in the future. If you can build long-term relationships with those who are supporting your cause, you lower overall costs incurred within your business.

More specifically, it’s a well-known fact that retention is significantly cheaper than garnering a new customer or donor. When you try to acquire a new donor, there is a litany of costs incurred that you do not have to deal with when you retain donors.

Brand loyalty

Imagine you are choosing between two brands of toilet paper. Brand A is the brand you’ve historically chosen. It’s plush, absorbent, and feels nice. You know a bit about the backstory of the brand, and they’re a humanitarian organization that donates part of its profits to homeless children.

Brand B, on the other hand, is a cheaper toilet paper that you’ve never used, and know nothing about.

Most of you reading would pick Brand A to keep purchasing – you know the product, the brand, and you feel comfortable in sticking with the company and their product, even though it is a more expensive option. The same fundamental rules apply to the non-profit industry.

If you, for example, as a non-profit, have done your due diligence and have spread your brand’s message far and wide, and have simultaneously taken good care of your current donors, you can be sure that the same result will happen in your favor.

More resources

This one should be a bit simpler to understand.

When you’ve already acquired a sponsor, there are minimal things that you need to do to retain them. If you keep the sponsor informed about where their donations are going, thank them for their generous support, and ask them for feedback, most people will tend to stay with your organization.

But to get a new donor? First, you have to build out lead-finding campaigns, whether that’s through Google Ads, hiring a specialist, or creating posts on social media. Then, you have to contact those leads through a variety of various contact methods – email, social media, handwritten nonprofit direct mail – and hope that one of those methods will grab their attention. Once you have their attention, you need a person with sales experience to convince the potential sponsor that your project and your brand is the one they should be donating to. Even still, there are tons of different types of people who may donate to your cause, and trying to market to all of them is a very difficult task.

At the end of the day, it should be quite intuitive to understand that getting a new person to sign up to provide a donation is a lot more difficult than having someone who has already donated do so again.

Marketing and advertising

This slightly ties into our last point, but any sort of marketing or advertising that you conduct has zero effect on those who have already donated to your brand. The point of setting up a social media campaign is to reach a wider audience, to get new customers and sponsors, not to re-engage with old ones.

If you invest a bit of time and effort into creating a better customer experience for people who have already donated, you can worry less about setting up perfect marketing and advertising campaigns since there is a higher return on investment for returning donors.

How to write an effective thanking letter to sponsor

Writing a thanking letter to sponsors in the non-profit industry is a key element in building a strong foundation of support.

An effective letter should be personalized and include details to show that their donation is greatly appreciated. Expressing gratitude immediately by addressing the donor’s name helps create an emotional connection with the reader.

In addition, provide specific examples of how the sponsor’s contributions have resulted in positive outcomes for your organization’s mission. In these situations, directly establishing what their donation was used for and how it aided your organization’s mission is crucial. Remember, people do not donate to a non-profit organization for the fun of it – they typically do so because it is a mission that they can stand behind.

Lastly, it is important to extend an invitation for future involvement, such as volunteering or providing additional donations. The idea here is to baby-step those donors you reach out to through the process of feeling appreciated, being told where their donation is going or has already gone, and following up by saying “Here are some actionable next steps to take that can help us even more”.

Following these steps will help create a successful thank you letter that will cultivate loyalty and appreciation from sponsors in the non-profit industry.

Gratitude doesn’t always have to be expressed through generic thank you cards or notes.

There are many other creative ways to show appreciation and demonstrate how much someone means to you. You can arrange a special event, such as treating your friends or family to a night out at the movies or planning an unforgettable picnic in the park. If you want something more permanent, there’s nothing wrong with buying a small present that not only has traction but also serves as a reminder of your appreciation long after the event itself.
