What did last year's gift actually pay for, and does your donor know? A renewal letter is not a new appeal. It is a report and an invitation to the same person who already said yes, and AI Donor Renewal Letter helps you write that letter with the numbers and the ask that fit this donor and this year.
Short answer: AI Donor Renewal Letter drafts a personal, mid length renewal letter that ties last year's gift to a specific outcome, names this year's specific need, and closes with a clear ask, so lapsing donors have a reason to renew instead of a generic appeal to ignore.
What is AI Donor Renewal Letter?
AI Donor Renewal Letter is a free web tool that writes a renewal letter to an existing supporter. You pass in the donor's name, the size and date of last year's gift, the program it funded, and the outcome it helped produce, plus this year's need and the amount you are asking for. The tool returns a letter with a subject line, a warm opening, the bridge from last year to this year, the ask, and a P.S.
The whole point is a letter that reads like it was written for one person. AI Donor Renewal Letter is not a mass appeal generator. It is the sit down at the desk and write back kind of letter, drafted quickly so you can send more of them.
Honesty matters more than polish. The numbers and the impact must be true. The tool writes the sentences; you supply the facts and check them before the envelope goes out.
Why Use AI Donor Renewal Letter?
Renewal rates rise when a donor sees a straight line from their money to a result. Generic year end letters do not draw that line. They talk about the mission in the abstract and hope the ask lands.
AI Donor Renewal Letter is built to draw the line every time. Last year you gave $250 to the after school program. That gift covered eight weeks of snacks and homework help for one child. This year we need to cover a second child, and your renewal at $250 closes the gap. That is the shape that renews.
The other win is time. Teams that write every letter from scratch send fewer of them. AI Donor Renewal Letter puts a solid draft in front of you in seconds, and you spend your minutes on the parts only you know.
Solicitation rules apply Charitable solicitation is regulated in most US states and in many countries. Verify the gift amount, the date, the program, and any impact figure against your CRM before you mail. Tax receipt and deductibility wording is regulated too, and this tool does not draft it. Your finance team or auditor writes that line, not AI Donor Renewal Letter.
How Does AI Donor Renewal Letter Work?
The interface sits on one screen. You start in the prompt box, where you paste the donor's details, the gift you are asking them to renew, and the story you want the letter to tell.
Above the settings you pick the writing engine. AI Donor Renewal Letter runs on your choice of models, including MSB AI, OpenAI ChatGPT, Anthropic Claude AI, Google Gemini, and DeepSeek. Warmer voice on one, tighter phrasing on another; if the first draft is not right, try another model.
Open the advanced options accordion to set Tone, Length, Formality, and Recipient, plus the toggles for a formal greeting, a formal sign off, contact information, and an enclosures note. The Assertiveness slider decides how firmly the ask lands. Hit Generate and the output card returns the letter with a live word count.
Every result carries Copy, Listen, Reuse, and Download, plus export to DOC, TXT, or HTML for your letterhead template. The activity history panel holds the drafts from your session, so you can line up the version for a lapsed monthly donor next to the version for a first time renewer without starting over.
| What you enter | Where it lands in the letter |
|---|---|
| Donor's name and salutation | The greeting and the personal opener |
| Last year's gift and program | The line that says what their money did |
| The specific outcome | The concrete impact paragraph |
| This year's need and amount | The ask and the P.S. |

Best Use Cases
The tool earns its keep any time you are writing back to a supporter who has already given.
| Situation | What to lead with | Suggested Length |
|---|---|---|
| Annual renewal at the same level | The outcome their last gift funded | Medium (300-450w) |
| Upgrade ask, small step | What the extra dollars would add | Medium (300-450w) |
| Lapsed donor (12 to 24 months) | An honest we miss you and one recent win | Short (150-250w) |
| Major donor personal letter | A named program and the executive director's voice | Long (500-700w) |
Setting Tone, Length, Formality, And Recipient
These four dropdowns and the toggles below them shape the whole letter. The Formality control is what changes the salutation and the sign off; the Recipient control changes the pronouns and the framing when you are writing to a company, a family foundation, or a partner nonprofit instead of an individual.
| Option | What it controls | When to change it | Suggested starting point |
|---|---|---|---|
| Tone | The feeling: Formal, Semi-formal, Friendly, Firm, Warm, Grateful, Assertive, Diplomatic | Match the relationship you have with this donor | Grateful, gratitude is the honest opener for a renewal |
| Length | Word budget: 1 paragraph, Short (150-250w), Medium (300-450w), Long (500-700w) | Longer for major donors, shorter for a mail merge | Medium (300-450w), fits one page cleanly |
| Formality | Register: Business, Casual, Legal, Personal, Diplomatic | Personal for individuals, Business for corporate donors | Personal, most individual donors prefer it |
| Recipient | Who receives it: Individual, Company, Government, Nonprofit, Group | Switch to Company for CSR contacts, Group for a family fund | Individual, the default for annual renewals |
| Include Formal Greeting | Adds Dear Ms. Surname style salutation | Off for donors on first name terms, On for new contacts | On, safer for a mailed letter |
| Include Formal Sign-off | Adds Sincerely, and a printed name and title | On for print, Off if you want a handwritten close | On, matches most letterhead templates |
| Include Contact Info | Adds a return phone and email under the signature | On for annual appeals, Off if the letterhead already carries it | Off, most letterhead already prints it |
| Include Enclosures Note | Adds an Enclosures line for the reply device | On when you mail a reply envelope or a giving form | On, most renewal packs include one |
| Assertiveness | Slider from 1 to 100 for how directly the ask is stated | Lower for lapsed donors, higher for engaged monthly givers | Around 55, firm but not pushy |
| Custom Instructions | Free text for the details only you know | Paste the donor name, last gift, program funded, outcome, and this year's need | Fill it in every time; the letter is only as specific as the brief |
Writing the Renewal Ask
A renewal ask has three moving parts: the retrospective sentence that says what the donor's last gift did, the current need that says what your organisation is doing next, and the specific amount you are asking for, tied to a specific outcome.
The mistake most letters make is skipping the middle part. They thank the donor, then jump straight to please renew today. AI Donor Renewal Letter is built to hold that middle beat: here is what we are doing next, and this is what your gift closes.
One outcome, one number A renewal letter is not the place to list every program. Pick one outcome that matches the donor's last gift and one number for this year's ask. The P.S. can point to something else if you must, but the body of the letter carries a single story from start to finish.
Example Inputs
Give AI Donor Renewal Letter the real details, not placeholders. The Custom Instructions field takes best to a brief that follows this order.
- Donor name, salutation, and the relationship you have with them.
- Last year's gift: amount, date, and the program it funded.
- The specific outcome that gift produced, in one sentence.
- This year's need and the exact amount you are asking for.
- The signer's name and title, plus any P.S. detail worth including.
Example Outputs
With a brief for donor Ms. Patel set to Grateful tone, Medium length, Personal formality, and Assertiveness around 55, AI Donor Renewal Letter returns something like this.
Subject: Ms. Patel, your gift kept one reader turning pages this year.
Dear Ms. Patel,
Last November you gave $250 to our After School Reading program. That gift bought eight weeks of snacks and one on one reading help for a nine year old named Micah. His teacher told us he moved up a full reading level between October and February.
This spring we are opening a second site, and one more child is on the waitlist for the same eight weeks of help. A gift of $250 from you closes that gap. It is the same amount you gave last year, and it does exactly what it did last year, for one more child.
If you can renew today, the reply card and envelope are enclosed. Thank you for reading with us. Sincerely, Priya Shah, Executive Director.
P.S. If you would like to hear how Micah is doing at year end, tick the box on the reply card and our program lead will write in June.
Tips and Common Mistakes
What works well
- Naming a specific outcome, not just the program.
- Anchoring the ask to a matching, believable number.
- Keeping the letter to one page for mailed appeals.
- Using the P.S. to open the door to a follow up, not to hide a second ask.
Where to stay careful
- The tool cannot check that your CRM number for last year's gift is right.
- It will happily invent an outcome if you do not name a real one.
- Legal and tax receipt language must come from your finance team.
- A too high Assertiveness setting can read as pressure to a lapsed donor.
Run this quick check before you print or send.
- ✅ The donor name and salutation match your CRM record.
- ✅ Last year's gift amount, date, and program are verified.
- ✅ The impact claim is one you can back up.
- ✅ This year's ask amount and any restricted use are approved internally.
- ✅ Required disclosures for your state or country are in the reply pack.
Segment before you generate Set up two or three donor segments (renewing at the same level, upgrade candidates, lapsed 12 to 24 months) and generate a version for each with AI Donor Renewal Letter. The activity history holds all three, so you can copy each into the right merge template.
Comparison Table
| Method | Speed | Personal feel |
|---|---|---|
| Reuse last year's letter | Immediate | Low |
| Write from scratch | Slow | High, fewer sent |
| Generic mail merge | Fast | Low |
| AI Donor Renewal Letter with a per donor brief | Fast | High |

Frequently Asked Questions
Do I need an account to use AI Donor Renewal Letter?
No. AI Donor Renewal Letter runs in your browser with no login, no card, and no credit meter. Paste the donor brief, pick a model, and generate; the letter is ready in seconds.
Can it write a letter for a corporate or foundation donor?
Yes. Change Recipient to Company or Group and set Formality to Business. The salutation and closing shift to fit a corporate contact or a family fund.
Will the tool draft the tax receipt language for me?
No, and it should not. Tax deductibility, receipt wording, and state disclosures vary by jurisdiction and are regulated. Have your finance team draft that line and keep it in a template you paste in separately.
How do I stop the letter from sounding generic?
Fill in the Custom Instructions field with a real name, a real last gift, a real program, and one specific outcome. AI Donor Renewal Letter is only as personal as the brief you feed it.
What Length should I pick for a mailed one page letter?
Medium (300-450w) is the safe default. It fits on one page with room for the letterhead and the signature, and it holds enough space for the retrospective, the ask, and the P.S.
How do I handle a lapsed donor who has not given for over a year?
Lower the Assertiveness slider, set Tone to Warm, and lead with an honest we miss you plus one recent win. Ask for the same amount they gave last, not more.
Can I export the letter straight into our mail merge?
Yes. Use Export DOC for a Word merge or Export HTML for an email platform. The output card also has a Copy button if you would rather paste it into your existing letterhead.
A renewal letter is the closest thing a nonprofit has to a private conversation with a supporter, and AI Donor Renewal Letter helps you have that conversation more often without dropping the specificity that makes donors say yes again. Thanks for the work you do on the other side of that envelope.
