Before you grab your copy, let’s break down why thank-you letters matter so much, what makes them great, and how Julep makes sending them easier than ever.

Why Thank You Letters Still Matter (And Always Will)

In a world full of pings, dings, and notifications, a genuine thank-you still stands out. Studies show that timely, thoughtful thank-yous help increase donor retention and inspire people to give again.

“A donor thank-you letter should go out within 48 hours of receiving a gift. It should include the exact donation amount for tax purposes, and clearly show how the gift will be used,” says Sofia Borden, Julep’s Chief Experience Officer. “That’s standard best practice in the nonprofit world, and it’s exactly what Julep helps you do more easily.”

Here’s the thing: your donors aren’t just giving money. They’re showing trust in your mission. And they deserve more than a canned response or a line-item receipt. Your thank-you should feel personal.

Unfortunately, many nonprofits fall into the trap of being too generic.

“The biggest mistake we see? Sending the same thank-you for a $25 donation and a $2,500 donation,” Borden adds. “Donors notice those details.”

The trend across the sector is clear: the best thank-you letters don’t just confirm the gift, they continue the conversation. Whether it’s a handwritten note, a quick phone call, or even a short video, the thank-you that makes someone smile is the one they remember.

Gratitude isn’t just nice. It’s strategic.

We’ve put together a full set of plug-and-play thank-you letter templates for all kinds of giving moments:

• First-time donor thank-you

“Every thank-you letter should include three things for tax compliance,” Borden explains. “Your EIN, the donation details, and a statement confirming no goods or services were exchanged.”

Personalization at Scale: Make Gratitude Smarter

You don’t have to choose between being efficient and being personal. With Julep, you can do both. Our CRM lets you tailor your thank-you messages using real donor data, like donor history, gift size, communication preferences, involvement with your organization, interests, family and friend connections, and more.

So instead of sending a generic “thank you for your donation,” you can send:

• A message that references the exact program the donor supported

• An email that goes out minutes after the gift is received

• A note using the donor’s preferred name and tone

Here’s a quick look at what Julep’s Donor Profile view gives you access to:

It’s everything you need to send thank-yous that are:

• More relevant

• More timely

• More strategic

Segment Like a Stewardship Pro

Want to send a handwritten letter to a major donor but an email to a recurring one? Easy. With Julep, you can segment your thank-yous based on:

• Gift size (think email vs. phone call vs. mailed letter)

• Gift type (one-time, recurring, event, in-kind)

• Donor stage (new, lapsed, loyal, or major giver)

This kind of segmentation helps your supporters feel seen and appreciated, not just lumped into a list that was exported into a mail merge in Word.

Want Better Retention? Test Your Gratitude

Not sure if a heartfelt story works better than a quick stat? You don’t have to guess. With Julep’s integrations with platforms like Constant Contact and MailChimp, you can run A/B tests on your thank-you emails to see what really resonates.

Try testing:

• Subject lines: “You made a difference, Jane” vs. “Your tax receipt from [Org Name]”

• Tone: Friendly and conversational vs. formal and polished

• Content format: Video thank-you vs. short written note

With every test, you learn what your donors respond to—and build stronger, more effective stewardship strategies.

Track Every Thank-You, Every Time

Keeping track of who’s been thanked (and how) can be a nightmare. But not with Julep. We have tools such as Thank You Notes Needed, which tell you who needs to be thanked. You can also track your last communications and what’s needed through Moves Management, and assign tasks like phone call follow-ups through Tasks.

Additionally, Julep helps you keep a full record of:

• When the thank-you was sent

• What format it was (email, phone call, mailed letter)

• Who sent it

• Whether it was opened, clicked, or ignored

No more guessing. Just smart, trackable gratitude.
