LYBUNT and SYBUNT Strategies to Reactivate Donors

Donor acquisition gets a lot of attention, but many nonprofits are sitting on a major growth opportunity they already own: lapsed donors.
If someone gave to your organization before, they have already crossed one of the biggest hurdles in fundraising. They know your mission, they trusted you enough to contribute, and at some point they believed their gift would make a difference. That makes them far more valuable than a completely cold prospect.
Two of the most useful tools for reactivation are LYBUNT and SYBUNT lists. These simple fundraising segments help nonprofits identify donors who have stopped giving and decide who to contact first, how urgently to reach out, and what kind of message is most likely to bring them back.
For nonprofit professionals trying to improve retention, stabilize revenue, and reduce overreliance on new donor acquisition, LYBUNT and SYBUNT strategies are practical, measurable, and highly effective.
What LYBUNT and SYBUNT mean
LYBUNT stands for Last Year But Unfortunately Not This. These are donors who gave last year but have not yet given this year.
SYBUNT stands for Some Year But Unfortunately Not This. These are donors who gave in a previous year, but not last year and not yet this year.
In plain terms:
- LYBUNT donors are recently lapsed donors
- SYBUNT donors are longer-lapsed donors
This distinction matters because recency is one of the strongest indicators of whether someone will give again. A donor who gave 10 months ago usually needs a different message than a donor who last gave three years ago.
Why LYBUNT and SYBUNT matter for donor retention
Many nonprofits know they have lapsed donors, but they do not always organize outreach in a disciplined way. A general "we miss you" email to everyone in the database rarely performs as well as a segmented campaign based on giving history.
LYBUNT and SYBUNT strategies help your team:
- Prioritize the donors most likely to renew
- Personalize messaging by lapse stage
- Forecast revenue more accurately
- Reduce donor attrition over time
- Improve fundraising ROI by focusing on warm audiences
This matters because retention is often more cost-effective than acquisition. Sector data consistently shows that keeping current donors engaged is essential for sustainable fundraising. Resources from organizations like Candid and industry publications such as Nonprofit Quarterly regularly highlight the operational and financial value of long-term donor relationships.
The difference between LYBUNT and SYBUNT strategy
While both lists are used for reactivation, they should not be treated the same way.
LYBUNT strategy: act quickly and specifically
LYBUNT donors are your highest-priority reactivation audience because:
- They gave recently
- Your organization may still be top of mind
- They may have intended to renew but forgot
- A simple, timely reminder can work
With LYBUNT donors, the goal is usually to:
- Remind them of their previous support
- Show recent impact
- Make it easy to give again
- Create urgency before the current giving cycle ends
SYBUNT strategy: rebuild connection and trust
SYBUNT donors usually need more context and more cultivation because:
- More time has passed since their last gift
- They may have changed priorities
- They may no longer recognize your recent work
- Their lapse may reflect disengagement, not forgetfulness
With SYBUNT donors, the goal is often to:
- Reintroduce your organization
- Share proof of relevance and momentum
- Invite low-friction re-engagement
- Ask for a renewed gift only after rebuilding interest
How to build LYBUNT and SYBUNT lists correctly
A strong reactivation campaign starts with clean segmentation.
Start with accurate donor data
Before pulling lists, make sure your donor records are updated and standardized. Review:
- Gift dates
- Gift amounts
- Recurring gift status
- Preferred communication channels
- Email deliverability
- Mailing address accuracy
- Notes from previous donor interactions
If your donor database is messy, your reactivation campaign will be too. Good donor management technology makes this easier by centralizing records, communication history, and reporting. If your team is evaluating systems, explore GiveRise features to see how streamlined donor data can support better segmentation.
Define your LYBUNT and SYBUNT timeframes
Most organizations use calendar-year or fiscal-year logic. For example:
- LYBUNT: gave in the prior fiscal year, but not in the current fiscal year
- SYBUNT: gave before the prior fiscal year, but not since
You can also create more refined segments, such as:
- LYBUNT under 6 months lapsed
- LYBUNT major donors
- SYBUNT 2 to 3 years lapsed
- SYBUNT 4+ years lapsed
- LYBUNT former recurring donors
- SYBUNT event donors only
The more your list reflects donor behavior, the more relevant your outreach can be.
Layer in additional segmentation
Do not stop at LYBUNT versus SYBUNT. Add filters like:
- Last gift amount
- Lifetime giving total
- Number of gifts
- Campaign or program affinity
- Volunteer history
- Event attendance
- Recurring giving history
- Donor acquisition source
For example, a donor who gave $25 once at an event should not receive the same reactivation sequence as a donor who gave $1,000 annually for five years.
Best practices for reactivating LYBUNT donors
LYBUNT donors are often your easiest win. Treat them like valued supporters who may simply need a relevant nudge.
1. Reach out before they drift further away
Timing matters. If a donor usually gives in spring and it is already early summer, do not wait until year-end to contact them. Build reports that flag donors shortly after their usual renewal window passes.
A practical schedule might look like this:
- 30 days after usual renewal window: friendly reminder email
- 45 to 60 days: impact-focused follow-up
- 60 to 90 days: phone call or personal note for higher-value donors
- Before year-end: stronger urgency message
2. Reference their past support
Specificity improves response. Instead of sending a generic appeal, acknowledge that they gave before.
For example:
- "Last year, your gift helped provide 200 meals during our summer outreach campaign."
- "You supported our scholarship fund last fall, and students are benefiting from that investment today."
This reminds donors that their giving mattered and reinforces identity: they are someone who supports your mission.
3. Emphasize recent impact
Show donors what has happened since their last gift. Use concise, credible outcomes such as:
- Number of people served
- Program expansion milestones
- Waitlist reductions
- New partnerships
- Urgent current needs
Be concrete. Impact statements like "your support changes lives" are less persuasive than "gifts from donors like you helped us place 47 families in temporary housing this quarter."
4. Make the next gift easy
Reduce friction in every channel. Include:
- A direct donation link
- Suggested giving amounts
- Mobile-friendly forms
- Clear recurring giving options
- Pre-filled or simplified donor information where possible
If donors have to search for your form or re-enter too much information, some will drop off.
5. Use multichannel follow-up
Do not rely on a single email. LYBUNT campaigns often perform best when they combine:
- Direct mail
- Phone outreach
- Text, where appropriate and permission-based
- Retargeting or digital reminders for larger campaigns
Even a simple two-channel strategy, such as email plus direct mail, can significantly increase the chance that your message is seen.
Best practices for reactivating SYBUNT donors
SYBUNT donors usually require a slower, more relational approach.
1. Reintroduce your mission
Do not assume they remember your current programs or priorities. Start with a concise reintroduction:
- Who you serve n- What has changed since they last gave
- Why your work is urgent now
This is especially important if your organization has evolved, expanded programs, or shifted strategy.
2. Start with engagement, not always an immediate ask
For donors who have been inactive for years, a non-ask touch can work well before a solicitation. Examples include:
- A short impact update
- An invitation to an event or webinar
- A program success story
- A survey asking what issues matter most to them
- A volunteer opportunity
This can help you identify who is still interested before launching a formal fundraising ask.
3. Test messaging by lapse length
A donor who lapsed 18 months ago may respond to a direct ask. A donor who has been inactive for five years may need more cultivation first.
Try segmenting SYBUNT donors by recency:
- 13 to 24 months lapsed
- 25 to 48 months lapsed
- 49+ months lapsed
Then vary your message, cadence, and ask size accordingly.
4. Update your assumptions about capacity and interest
Some SYBUNT donors may have greater giving potential today than when they last contributed. Others may have disengaged completely. Use wealth indicators, engagement history, and recent interactions to prioritize outreach thoughtfully rather than treating the entire list the same.
5. Clean your file as you go
Reactivation work is also database maintenance. As you contact SYBUNT donors, track:
- Invalid email addresses
- Returned mail
- Do-not-contact preferences
- Changes in donor interests
- Deceased records
For tax-deductible gifts and receipting standards, always make sure your acknowledgment practices follow current requirements from the IRS.
Messaging examples for LYBUNT and SYBUNT donors
Here is how the tone often differs.
LYBUNT example
Subject: You made a difference last year
Hi Maria,
Last year, you helped fund after-school arts programming for local students. Because of support from donors like you, 85 young people completed our spring workshops this year.
We noticed we have not yet received your annual gift, and we would be honored to have your support again. A gift of $50 today can help provide supplies for one student for the next session.
[Give now]
Thank you for all you made possible.
SYBUNT example
Subject: See what your past support helped start
Hi James,
A few years ago, you supported our community health outreach work, and we are grateful. Since then, our services have expanded to three new neighborhoods, helping more families access screenings and follow-up care.
We would love to share a quick update on where the program is today and what comes next. If you are still passionate about equitable access to care, we invite you to reconnect with our work.
[Read the update] [Support the next phase]
This kind of framing respects the donor relationship without assuming immediate readiness to give.

Week 4: Send follow-up email with urgency or matching opportunity
Week 5-6: Mail postcard or letter
Week 6-8: Staff or board calls to top-tier donors
Week 10-12: Final reminder before campaign deadline
For SYBUNT donors
Week 1: Pull and clean list
Week 2: Send re-engagement message or impact update
Week 4: Invite event attendance, survey completion, or story engagement
Week 6: Send tailored ask to engaged responders
Week 8-10: Follow up with selected donors by phone or mail
Week 12: Review reactivation, suppression, and stewardship next steps
Metrics to track in LYBUNT and SYBUNT campaigns
If you want to improve over time, track more than total dollars raised.
Key metrics include:
- Reactivation rate
- Revenue recovered
- Average reactivated gift size
- Cost to reactivate per donor
- Email open and click rates
- Response by segment
- Percentage converted to recurring donors
- Percentage marked inactive or undeliverable
You should also compare:
- LYBUNT versus SYBUNT response rate
- Personalized versus generic messaging performance
- Email-only versus multichannel results
Over time, these insights help you build a repeatable reactivation system rather than running one-off win-back campaigns.
Common mistakes to avoid
Even experienced fundraising teams can reduce results by making a few preventable errors.
Treating all lapsed donors the same
A single blanket appeal ignores recency, giving level, and donor motivation. Segment first.
Waiting too long to follow up
The longer a donor goes without hearing from you, the harder reactivation becomes. LYBUNT outreach should happen early.
Focusing only on the ask
If every message is a solicitation, SYBUNT donors especially may ignore you. Rebuild connection first when needed.
Ignoring donor experience after reactivation
Winning a donor back is only half the job. Once they give again, move them into a stewardship plan with prompt thanks, impact reporting, and future retention touches.
Overlooking technology and reporting gaps
If your team cannot easily identify LYBUNT and SYBUNT lists, track outreach, and measure results, you are working harder than necessary. The right platform can make donor segmentation and campaign follow-up much simpler. If you are comparing tools, review GiveRise pricing to see what fits your team and budget.

Conclusion
LYBUNT and SYBUNT strategies give nonprofits a practical framework for one of the most important fundraising priorities: reactivating donors who already know and trust your mission.
LYBUNT donors often respond to timely reminders, personalized impact, and easy renewal paths. SYBUNT donors typically need more intentional re-engagement, clearer storytelling, and a stronger case for why your work matters to them now. In both cases, success comes from using donor data wisely, segmenting thoughtfully, and following up consistently.
If your organization wants to improve donor retention without constantly chasing new names, a smart reactivation strategy is one of the highest-value places to start.

Frequently asked questions
What is the difference between LYBUNT and SYBUNT?
LYBUNT refers to donors who gave last year but not this year, while SYBUNT refers to donors who gave some previous year but not last year or this year. LYBUNT donors are usually more recent and often easier to reactivate.
Which donor group should nonprofits prioritize first?
Most nonprofits should prioritize LYBUNT donors first because they have given more recently and are generally more likely to renew with a timely, personalized reminder.
How often should nonprofits run LYBUNT and SYBUNT reports?
At minimum, run these reports monthly during active fundraising periods and quarterly year-round. More frequent reporting helps your team catch lapsed donors before they become harder to win back.
What channels work best for donor reactivation?
Email is often the fastest starting point, but reactivation usually performs better with a multichannel approach that may include direct mail, phone calls, text messaging, and personalized outreach for higher-value donors.
Should SYBUNT donors always receive a fundraising ask right away?
Not always. For longer-lapsed donors, it can be more effective to begin with an impact update, event invitation, or engagement touch before sending a direct solicitation.
How can donor management software help with LYBUNT and SYBUNT campaigns?
Donor management software helps nonprofits identify lapsed donors quickly, segment by recency and giving history, track outreach, automate follow-ups, and measure which reactivation efforts generate the best results.
